2001 Toyota Sat Nav Press Kit



Toyota and Lexus will offer satellite navigation on 12 models before the end of 2001.
The TMC satellite navigation system has breakthrough DVD data storage, for faster route calculation and re-calculation.

A single DVD contains all the road-map data for Australia.

The DVD-based navigation process provides significantly faster processing time than CD-ROM - and hence faster route selection, map scrolling and re-routing.

Eleven of the 12 Sat Nav models will have exclusive touch-screen menu selection and scrolling.

First to be launched with satellite navigation will be Lexus IS 300 and upgraded IS 200 Sports Option.

They will be followed a month later by Toyota Celica, Tarago, RAV4 and Prius, and Lexus LS 430, SC 430, GS 300 and ES 300.

By year's end, Sat Nav will also be available on Toyota Avalon, Corolla and Avensis Verso.

LandCruiser 100 Series, LandCruiser Prado, Lexus LX 470 and Camry will be offered with Sat Nav in late 2002.

The Sat Nav system for most Toyota vehicles and Lexus ES 300 will have an audio replacement unit with radio/cassette, single CD, fold-down screen and touch-screen menu selection.

Flagship Lexus LS 430, Lexus GS 300 and new Lexus SC 430 will have a fully-integrated electro-multi vision (EMV) system with touch-screen control.

Lexus IS 300 and IS 200 Sports Option have the option of a remote control type system, with a pop-up screen out of centre dashboard and a remote control built into the centre console.

The Toyota system's dual maps can be tailored to suit the individual user - in both map scale and heading.

Either or both maps on the dual-map screen can be oriented north ~up~ or heading ~up~.

When using the dual-map mode, the system will - on turn approach - automatically ~flip~ the right-hand map to show an intersection diagram.

The dual-map function can provide both a route overview and a close up of the turns.

The system also has a unique route preview function.

Toyota's Sat Nav system provides for multi-destination input.

Additional destinations can be added to the route at any time while the vehicle is stationary.

As well as adding destinations, the user can re-order the destinations/waypoints.

• Toyota Motor Corporation's new in-car navigation system uses 28 satellites which are the property of the US Department of Defence.
• Between six and 12 GPS satellites are in view over Australia at any time.

• US President Ronald Reagan made the US-military developed GPS commercially available and President Bill Clinton introduced his May 2000 protocol which removed selective availability and increased the accuracy to plus/minus 10 metres.

• GPS is so accurate it is used to warn of earthquakes by monitoring movement of the earth's tectonic plates.

• Toyota Motor Corporation's Sat Nav system is the first implementation in Australia of digital map data on a DVD.

• In an Australian first, map data supplier Pacific Access is locally manufacturing the map DVD.

• Military and civilian cartographers took 30 years to create the first full map coverage of Australia.

• Pacific Access took four years to develop its electronic mapping techniques and to map metropolitan Melbourne. It then mapped metropolitan Sydney in 12 months.

• Major Sir Thomas Mitchell was responsible for surveying much of the eastern part of Australia in the period 1831-45. The NSW Surveyor-General's method for measuring distance was to count the strokes of his horse's hoof. Mitchell reckoned 950 paces equaled a mile. At the completion of each mile he would take a new compass bearing and re-start the count.

Toyota has released a car in Japan which uses satellite navigation to read the road ahead and automatically change down gears for a corner.
Navi-A1-Shift is fitted to the newly launched Verossa sports sedan.

The DVD-based navigation system interfaces with on-board ECUs to gauge speed and throttle opening and to access a memory of the driver's acceleration and braking patterns.

It may then decide to drop the car down into fourth or third gear for the upcoming corner.

The new feature is part of Toyota's commitment to Advanced ITS (Intelligent Transport System).

Within Japan, Toyota is already working with FM Multiplex broadcasts which allow the car to receive and react to real time navigational advice.

Voice actuation is already in use.

The driver can command the car's air-conditioning, audio and navigational systems.

Features of the developments are candidates for inclusion in Australian vehicles where applicable in future models.

Intelligent transport systems are regarded by Toyota as the future for the automobile.

It includes under the heading "Wired Transport" innovations like Mayday calls, traffic information advice and electronic toll collection.

On board electronics have already made significant safety advances.

Vehicle Stability Control (VSC) introduced on Lexus combines ABS (anti-lock brakes) and TRC (traction control) to automatically correct the car if it goes into a slide.

Enthusiastic drivers can switch off the system.

Toyota and Lexus have made a significant commitment to satellite navigation systems in Australia.
The new Denso developed system employs fast response DVD storage and touch screen actuation - both for the first time in this market.

The commitment by Toyota provides the potential for up to 50 percent of the 150,000 vehicles it delivers annually to now be fitted with Navi.

In reality initial take up is likely to be no more than 2.5 percent.

Toyota has been at the forefront of mass market introduction of new automotive technology.

In the second half of the 1980s it adopted Twin Cam Multi-valve technology in its volume models, and in the 1990s it made a near universal commitment to ABS, anti-lock braking.

Other makers had introduced both Twin Cam and ABS previously but Toyota's commitment on a much larger scale drove acceptance up and price down.

Four Lexus models and two Toyota models will now be fitted as standard with Navi.

Another seven Toyotas and two Lexus will offer Navi as an option.

~It's possible to foresee the time when on-board Intelligent Transportation Systems such as Navi will be as near standard a feature as a car radio,~ Toyota senior executive vice-president John Conomos said.

~Toyota has wisely waited to introduce a Sat Nav system until it has been able to simplify its operation and streamline its response.~

Satellite Navigation systems were in a fledging state in Australia.

It is estimated no more than 15,000 cars of all makes are currently fitted with Sat Nav.

~Toyota alone will put around 25 percent on that volume in the next twelve months,~ Mr Conomos said.

~Like cellular phones, Sat Nav will initially be sought by early adopters, but their enthusiastic response will drive a far larger market response.~

The production of a national grid by Pacific Access enables each town and locality to be mapped in great detail.

Current mapping ability encompasses major capitals and primary national road networks as well as offering some coverage of regional cities.

The on-board DVD storage system developed by Denso for Lexus and Toyota provides capacity great enough to capture all Australia and to provide value added customer services.

~DVD Navi is a great opportunity for Lexus in particular to build on its reputation for providing its customers with services they cannot easily access elsewhere,~ Mr Conomos said.

Toyota and Lexus view satellite navigation as an aid to driver safety.
Fast response made possible by DVD and timely voice guidance will help achieve the safety objective.

~Without doubt Sat Nav is a big step forward from a hard copy street directory,~ Toyota senior executive vice-president John Conomos said.

~But it is only so when it offers near instantaneous response - and that requires at the very least DVD technology.

~It is highly desirable to have a voice guidance system, ensuring that drivers can keep their eyes on the road.~

And only the Toyota/Lexus system offers DVD actuation.

Mr Conomos said engineers would face the challenge of balancing the need to impart information and preventing it becoming a distraction.

~There must be a point at which the driver could potentially become overloaded with information,~ he said.

~It's for that reason Toyota elected to enter the satellite navigation market only when it could guarantee fast delivery and easy communication.~

Touch screen technology, currently unique to the Toyota/Lexus system would do a lot to simplify the use of Sat Nav.

~Some units require a degree of computer literacy - and that is not particularly friendly in an in-car environment,~ Mr Conomos said.

~We learnt some time ago with car audio systems the necessity to simplify operation.

~It is a significant safety factor.~

Toyota also points out that the satellite navigation system does not remove from drivers the ultimate responsibility for making their own careful decisions about safety on the road.

Toyota Motor Corporation has developed three satellite navigation systems, for Toyota and Lexus models.
All three systems use a TMC-specific operating system.

Flagship Lexus LS 430 and Lexus GS 300 will have as standard equipment a fully integrated electro-multi vision (EMV) system with touch-screen control for the heater/ventilation system and audio as well as navigation.

New Lexus SC 430 will have a similar EMV-type system.

The EMV-type system will be optionally available on Toyota Prius.

Standard equipment on Lexus ES 300 and Toyota Avalon Grande will be an audio replacement AVX-type (audio-visual and external navigation) system, with radio/cassette, single CD, fold-down screen and touch-screen menu selection.

The AVX-type will also be optionally available on Toyota Celica, Tarago, RAV4, new generation Corolla and new Avensis Verso.

Lexus IS 300 and IS 200 Luxury Sports Option have the option of a remote-control type system, with a pop-up screen out of the centre of the dashboard controlled by a pad on the console.

Lexus developed this system specifically for the IS model - where it was deemed for safety reasons that the screen was too far away for easy use.

TMC's new satellite navigation system has Australia's first DVD map data storage.
The DVD in TMC's Sat Nav system can store approximately five times as much data as a single CD-ROM, based on a CD-ROM with maximum storage of 800Mb.

A single DVD contains all the road-map data currently available for Australia.

TMC's DVD-based navigation process provides significantly faster processing time than CD-ROM - and hence faster route selection, map scrolling and re-routing.

The DVD uses a smaller laser beam than a Compact Disc (CD).

It can therefore handle pits (or signal grooves) at a higher density.

A 12cm single-layer Digital Versatile Disc (DVD) can store 3.95 gigabytes of signal data - five times the data of a CD-ROM.

The system can accept a dual-layer DVD ROM (which provides a maximum possible storage of 8.5 gigabytes) should future data storage requirements demand it.

back to top 


TMC's unique DVD-based satellite navigation system consists of six dedicated components.
The components are a GPS antenna, display screen, DVD-ROM, navigation electronic control unit, GPS receiver and a gyro sensor.

The GPS receiver and gyro sensor are contained in the navigation ECU unit.

The gyro sensor provides information on yaw rate (turning rate) of the vehicle.

The GPS antenna is positioned inside the windscreen or rear window (depending on model).

The navigation ECU is positioned under the front passenger's seat or in the boot (depending on model).

A touch display screen will be standard equipment for 11 of the 12 Lexus and Toyota models offered with satellite navigation.

In addition to its dedicated components, the TMC Sat Nav system uses the vehicle's speed sensor and reversing lamp signal.

The Sat Nav voice instructions are transmitted through the main speaker in the driver's door.

Information from the gyro sensor, speed sensor and reverse signal allows the system to provide continuous navigation information during periods when the GPS antenna is out of ~sight~ of the GPS satellites.

The Sat Nav system continues to function when the vehicle passes under a bridge or is in a tunnel.

Toyota Motor Corporation is the only manufacturer to offer touch-screen control for its satellite navigation systems in Australia.
It has developed three DVD-based Sat Nav systems for Lexus and Toyota models.

Two of the three systems have touch-screen operation.

Touch screen provides a key pad to input destination address or points of interest, and for the Toyota Sat Nav system's Calendar & Memo function.

A directory function assists with spelling of street and location names.

The touch screen also provides zoom in/zoom out and scroll functions at a finger touch.

TMC's leading-edge satellite navigation is the combined product of Toyota, Denso, Pacific Access and various audio product suppliers such as Fujitsu Ten, Panasonic and Pioneer.
Pacific Access - a joint venture of map maker UBD and telecommunications company Telstra - provides the road map data.

Denso builds the navigation processor and developed the Toyota Sat Nav operating system.

The operating system is in the KIWI-W format.

Fujitsu Ten, Panasonic and Pioneer provide the touch-screen audio-replacement head units.

The map creation process begins at Pacific Access with the raw map data.

Pacific Access provides the road-map data for all vehicle Sat Nav systems in Australia.

The Toyota system's advantage lies in the use of the data through Toyota's employment of the KIWI-W operating system and DVD data storage.

Map information crosses the Pacific twice before it is committed to DVD.

Pacific Access produces intelligent electronic data, which goes to Denso for conversion to the KIWI-W format.

The map DVD is produced for Australia by both Pacific Access and Denso Japan.

Local Development:
Local development of Toyota satellite navigation has included three formal evaluations, a confirmation drive and more than 20 weeks of Denso evaluation driving.

Toyota Australia has had a Sat Nav equipped vehicle in each region for on-going confirmation testing since May 2001.

Many versions of the local software were written and evaluated prior to launch.

The Toyota satellite navigation system's leading-edge software provides unique features, including route preview.
The system can calculate a route from Cronulla in Sydney to Fremantle near Perth (a distance of 4200 kilometres) in approximately four seconds.

In city routes, the Toyota Sat Nav system provides quickest, shortest and alternate routes.

It calculates ideal (traffic-free) travelling time depending on road type and the average speed for the type of the road (as defined by the user).

As part of the route calculation process, the user can insert special conditions - such as to avoid toll roads, avoid motorways and avoid the use of ferries.

The Toyota system's combination of unique touch-screen control and software allows the user to input multiple destinations and re-order destinations at the touch of a button.

A unique feature is route preview, where the system will automatically scroll the selected route, by pressing the FF symbol.

In addition, the Toyota system offers a choice of three dual-map modes.

Toyota's satellite navigation system was designed for safety.
It was created as a driving aid complete with special features to minimise distraction.

Actions such as inputting a new destination must be done while the vehicle is stationary.

The system can be used with a choice of split-screen options or with voice-direction only.

There are audible warnings on approach to turns and at the turn. One tone is for approach and two for the turning point.

Auto Interior magazine recently praised the Lexus LS 430 navigation system as a safety feature, with the magazine awarding LS 430 its Interior of the Year award.

Toyota Sat Nav's speed of route re-calculation also contributes to safety.

The DVD-based system's rapid route re-calculation means that the driver is given new route directions almost immediately.

The recalculation is so rapid that often the driver isn't aware that a turn has been missed.

This reduces stress, by ensuring the driver is not left in limbo waiting for new directions.

Toyota's satellite navigation system is launched with map data covering approximately 172,000 km of roads.
Pacific Access is a leading Australian content management, publishing, location and e-business solutions company, providing print, voice and online products and services.

As a national, wholly-owned subsidiary of Telstra Corporation Limited, Pacific Access manages two of Australia's leading brands, Yellow Pages® and White Pages™, along with the interactive mapping and guidance brand, WhereiS™, and the GOeureka™ internet search machine.

Pacific Access electronically mapped the nation's highways and major urban areas to produce the software data used in satellite navigation systems.

Pacific Access has formed an alliance with Universal Press and uses, UBD™ maps to develop and create location and navigation databases.

Mark Dennis, Pacific Access' Project Manager, WhereiS™ Core Database, said the company is now a forerunner in creating location and navigation databases.

~Pacific Access is the only company in Australia doing this work,~ Mark Dennis said.

~There is a team of around 45 people in the Pacific Access Location and Navigation group working on this technology.

~We take the paper map data from UBD™ and import that into a geographical information system, to create an intelligent transport system database that can route through the road network with full turn by turn guidance.~

Mark Dennis said it took Pacific Access four years to manufacture the first intelligent map data for Melbourne.

~We had to teach ourselves the ISO standard GDF (Geographic Data File), then how to make a navigational database, as well as build the maps,~ he said.

~Then we had to build the software to manufacture a database that manufacturers could accept in the automotive industry. As we expanded our knowledge, we worked more efficiently.

~It took just 12 months to build the electronic maps of Sydney, and another 12 months to do Brisbane and the coastal strip from the Gold Coast to the Sunshine Coast.

~Next we mapped Canberra, the other State capitals, and rural New South Wales, Queensland and Western Australia. We're now mapping the State roads and regional urban areas, such as Goulburn.

~We have people out on the road up to ten hours a day, for six weeks at a time, to check the raw (paper) map data,~ Mark Dennis said.

~For each day in the field there are correspondingly many days required in the office, building the information and making it intelligent.~

Pacific Access' field vehicles are equipped with Differential GPS (Global Positioning Satellite) for location accuracy and to capture specialist data on precision video.

Specialist information added into the intelligent mapping process includes data on direction of traffic flow: one way streets, right-turn and left-turn exclusions, manoeuvres instructions and points of interest such as restaurants.

~In five years time we should have all towns with 4000 people or more on the street network,~ Mr Dennis said.

~You will then be able to have full turn-by-turn map guidance from a Brisbane suburb to a street address in Broken Hill or Albany.~

TMC's new in-car navigation system uses 28 US Department of Defence satellites.
The global positioning satellites are in orbit at points around the earth.

Between six and 12 satellites are in view over Australia at any time. Any fix of the vehicle's position requires information from three or four satellites.

The satellite navigation system calculates the position, based on the principle of three-point measurement.

Each GPS satellite has four high-precision atomic clocks - allowing the satellite to transmit continuous orbit signals and radiowave transmission time signals.

Each clock is accurate to within one second per 300 years.

The navigation ECU in the Sat Nav-equipped vehicle also has a clock, which can measure the time taken for radiowave time signals to travel from each satellite to the receiving antenna.

Each time interval is multiplied by the luminous flux (the rate of transmission of luminous energy - approximately 300,000 kilometres per second) to determine the distances from the satellites to the antenna.

The positions of the GPS satellites are known by their signals, so the navigation ECU can then determine its position relative to the satellites.

The ECU does this by rendering the receiving point (vehicle position) as the point where the four spheres of satellite transmission signals converge.

However, differences may exist between the clocks in the satellite and the clock in the vehicle navigation ECU, so the three or four spheres may not converge at a single point.

The ECU therefore uses another satellite to calculate the point at which the spheres converge at a single point and corrects its internal clock relative to the clocks in the satellites.

Other Sat Nav Systems:
GPS is one of several satellite-based navigation systems in use or under development around the world.

Russia's GLONASS system is a counterpart of GPS, with 24 satellites.

However, due to launch schedule delays, GLONASS currently has ten healthy satellites.

Experimental development on Europe's Galileo system began in 1999 and the system is due for full operation in 2007-2010.

China launched its first Beidou (Northern Dipper) navigation satellite in October 2000.

The Toyota satellite navigation system uses the United States Global Positioning System (GPS) satellite network.
Civilian GPS was, until 2000, limited in its accuracy due to selective availability.

The Clinton Protocol of May 2000 ended selective availability, which increased accuracy from 100 metres to plus or minus 10 metres.

The accuracy of GPS has created uses far beyond the military navigation, position fixing and timing needs for which it was developed.

GPS is now used to measure the movement of the earth's tectonic plates - and hence provide earthquake warnings.

It is also used in taxi dispatch, in-car navigation, emergency vehicle response, agriculture, autonomous vehicle operation in farming and mining, surveying and mapping for mining and construction, and recreational activity such as bushwalking.

The satellite-based GPS is the answer to an old navigator's wildest dream - an instantaneous, all-weather, 24-hour, worldwide positioning system accurate to within plus or minus 10 metres.
Electronic navigation had its beginnings with the use of radio beacons.

Sir Charles Kingsford Smith's pioneering 1928 Trans-Pacific flight used radio beams for guidance on sections of the Oakland-Honolulu leg.

In the 1930s, radio beacons were used to provide blind approach guides at aerodromes.

The problem of navigating aircraft at night, often in cloud, assumed great importance in World War II.

Night-time dead reckoning navigation was highly inaccurate.

Technology from radio blind-approach systems was used as the basis for the German Knickebien guidance beams.

Britain's answer to the same problem was a passive, grid-type radio navigation system known as ~Gee~. Gee consisted of three linked transmitters, each about 160km apart, transmitting a train of radar-like pulses.

The pulses created a grid, and hence the system's nickname Gee.

Bombers carried a receiver and a cathode ray tube.

The navigator identified and measured the time intervals of the pulses on his cathode ray tube, then referred to a specially colour-coded Gee chart.

Initial accuracy was two miles at range of 250 miles.

Evolutions of the Gee system were still in civilian use in the 1990s.

The United States later adopted Gee, but used it with lower frequencies to increase its range to 1000 miles.

The US system was named LORAN, for long-range navigation, and was still in use at the end of the 1990s.

Germany developed a similar long-range radio aid called Electra Sonne, using a system of linked transmitters from Bay of Biscay to Norway.

This system was still in operation at the end of the 1970s under the name Consol.

The system suited weekend yachtsmen, as it required only a simple radio receiver and a special chart.

In the 1960s, the United States developed the Omega radio navigation system.

It provided worldwide electronic navigation coverage for the first time.

The Omega system used huge radio towers positioned around the world, including one in Victoria.

Satellite navigation also began in the 1960s, with the US Navy's NAVSAT or TRANSIT system.

TRANSIT was the world's first operational satellite positioning system. However, it was not instantaneous.

TRANSIT's six satellites gave worldwide coverage every 90 minutes and accuracy to within 200 metres.

Positions were determined by measuring the Doppler shift effect of the satellite signal.

The system was in use until 1996.

TMC's new satellite navigation system has a range of unique features including touch-screen control, DVD data storage and a choice of dual-map combinations.
The Toyota system's dual maps can be tailored to suit the individual user - in both map scale and heading.

Either or both maps on the dual-map screen can be oriented north ~up~ or heading ~up~.

When using the dual-map mode, the system will - on turn approach - automatically ~flip~ the right-hand map to show an intersect diagram.

The dual-map function can provide both a route overview and a close-up of the turns.

The dual-screen choices are:
• two maps
• location map with next turn
• location map with list of next three turns.

Alternatively, the screen can be set up with a single map.

In all screen settings, the system will insert a next intersection tulip diagram on approach to turns.

A unique Toyota feature is a route preview function. This allows users to preview the whole route, simply by pressing the FF button.

Toyota's Sat Nav system provides for multi-destination input.

The user can add destinations to the route at any time and also re-order the destinations/waypoints.

For safety reasons, the destinations and other complicated functions can only be programmed while the vehicle is stationary.

Toyota's Sat Nav has two reminder functions - a calendar function, with adjustment for location and times zones, and a vehicle maintenance reminder.
