TOYOTA REVEALS NEXT-GENERATION INTEGRATED SAFETY TECHNOLOGY
- Vehicle-to-infrastructure and vehicle-to-vehicle communications for safer manoeuvres and hazard alerts
- Vehicle-to-vehicle communications for smarter, safer and more efficient cruise control driving
- Better night-time illumination with new adaptive LED headlight arrays
- New technologies to be rolled out from 2015, together with advanced active safety packages for new models
Toyota has today revealed some of the smart new technologies and systems it will be featuring in future models to make driving safer. True to the company’s Integrated Safety Management Concept, these have been designed from the start to work together to help cut the number of road accidents.
The new features, announced at a safety seminar in Toyota City, will be rolled out in new models from 2015. Toyota is also creating Safety Sense active safety packages, tailored to suit different size vehicles that will be made available worldwide by the end of 2017.
Vehicle-infrastructure and vehicle-vehicle communications
When you pull up to a blind junction, sometimes even the best on-board cameras and sensors can’t give you clear warning of the potential hazards. Toyota has worked to eliminate the risk with new vehicle-to-infrastructure and vehicle-to-vehicle communications, using a wireless frequency reserved for ITS – Integrated Traffic System – services.
For example, when you arrive at junction with no clear view, sensors above the road will detect on-coming traffic or pedestrians crossing the road and send the information to your car – the vehicle-to-infrastructure system.
Vehicles approaching the intersection will signal their presence using the vehicle-to-vehicle link, activating visual and audio driver warnings when necessary to help prevent an accident.
Toyota has also developed a new Communicating Radar Cruise Control that uses vehicle-to-vehicle communication to make it easier for preceding and following vehicles to keep a safe distance apart. It uses a forward-facing millimetre-wave radar to monitor the distance between your vehicle and the one ahead, their relative speed and the acceleration/deceleration of the car in front. This significantly improves tracking performance in traffic, being safer and more fuel-efficient, and helping avoid one of the common causes of congestion.
Toyota develops its ITS-compatible systems working in collaboration with government bodies, agencies and private companies, with the aim of launching them as soon as practically possible. In 2013, Toyota participated in the ITS Green Safety public-private collaborative demonstration project to assess the social effects of such systems. It will also be participating in the ITS Connect Promotion Consortium to support the development of environments for the smooth introduction of such systems and their widespread adoption.
LED Array Adaptive High Beam
Toyota has already made important advances in automatic high beam and adaptive lighting systems. Now its next-generation system is ready to deliver even better night-time illumination – the LED Array Adaptive High Beam.
This system uses multiple, independently controlled LEDs arranged in a single row. This gives a wider illumination without dazzling drivers of on-coming or preceding vehicles. It can light up the gaps between vehicles ahead and those approaching, making it easier to spot pedestrians; light distribution is also linked to use of the steering wheel, giving better visibility as you turn into a bend.
Toyota’s development of next-generation illumination technologies is part of the company’s efforts to help prevent accidents at night. The new Toyota Safety Sense active safety package (details below) will include an automatic high beam function.
Toyota active safety packages
From 2015, Toyota will launch a new set of active safety technologies design to help prevent or mitigate collisions across a wide range of vehicle speeds. They will be offered in two Toyota Safety Sense packages, initially in Japan and subsequently in the USA and Europe, by the end of 2017.
The two packages – designated C and P for mid-size and larger vehicles respectively – bring together several of Toyota’s existing active safety technologies, including the Pre-Crash Safety system, Lane Keep Assist and automatic high beam. The C package uses a laser radar and the P package a millimetre-wave radar, each combined with a camera to secure high performance and reliability.
A separate active safety package, Lexus Safety System+, will be marketed for Lexus models, including a new Road Sign Assist function. This recognises speed limits and road signs when travelling overseas, presenting the information on the driver’s instrument display.
Toyota to Roll Out Brand New Active Safety Packages from 2015
Toyota City, Japan, November 26, 2014?Next year, Toyota Motor Corporation will launch a newly-developed set of active safety technologies designed to help prevent or mitigate collisions across a wide range of vehicle speeds. These technologies will be offered in the form of two “Toyota Safety Sense” packages, to be launched in 2015 and rolled out across most passenger models and grades*1 in Japan, North America and Europe by the end of 2017. Both packages will be made available at price levels chosen to encourage widespread use.
Two packages will be available depending on vehicle type?a “C” package for compact cars and a “P” package for mid-sized and high-end cars. Toyota Safety Sense C integrates several of Toyota’s existing active safety technologies: the Pre-Collision System (PCS) helps prevent and mitigate collisions; Lane Departure Alert (LDA) helps prevent vehicles from departing from their lanes; and Automatic High Beam (AHB) helps ensure optimal forward visibility during nighttime driving. As part of a multi-faceted approach to active safety, Toyota Safety Sense packages combine laser radar (C package) or millimeter-wave radar (P package) with a camera, achieving high reliability and performance.
Toyota Safety Sense C
The Toyota Safety Sense C package features three proprietary active safety technologies, and combines a camera and laser radar for outstanding performance and reliability. The package helps prevent or mitigate collisions even at high speeds.
Pre-collision System (PCS)
PCS uses a camera and laser radar to detect objects ahead of the vehicle, and when there is a possibility of collision it prompts the driver to brake with an audio and visual alert. When the driver notices the hazard and brakes, the system provides additional braking force. If the driver fails to brake in time, the system automatically applies the brakes, reducing speed by approximately 30 km/h*2 in order to prevent or mitigate the collision. The operational range of PCS covers speeds at which at least 80 percent of rear-end collisions occur (i.e. relative speeds of between approximately 10 km/h and 80 km/h).
Lane Departure Alert (LDA)
LDA uses a camera to detect white and yellow lane markings. If the vehicle starts to deviate from the lane, LDA alerts the driver with an audio and visual alert.
Automatic High Beam (AHB)
AHB helps ensure excellent forward visibility during nighttime driving. It uses a camera to detect the headlights of oncoming vehicles and the tail lights of vehicles ahead, and then automatically switches between high beams and low beams so as not to dazzle other drivers.
Toyota Safety Sense P
Toyota Safety Sense P combines a camera and millimeter-wave radar for outstanding performance and reliability. In addition to the three active safety technologies included in the Toyota Safety Sense C package, the Pre-collision System offered with this package also includes a pedestrian detection function. In addition, Toyota Safety Sense P offers Radar Cruise Control functionality.
Pre-collision System with pedestrian detection function
This system uses millimeter-wave radar and a camera to detect pedestrians in addition to vehicles. To help prevent or mitigate collisions, the system activates an audio and visual alert in addition to brake assist, followed by automated braking if the driver does not brake in time. Automated braking operates at relative speeds of between 10 to 80 km/h for potential collisions with pedestrians, and can reduce speed by approximately 30 km/h*2. For potential collisions with vehicles, the enhanced PCS system included with the Toyota Safety Sense P package operates at relative speeds of between 10 km/h and the vehicle’s top speed, reducing speed by approximately 40 km/h*3.
Radar Cruise Control
On highways, Radar Cruise Control uses millimeter-wave radar to detect preceding vehicles and determine their speed. It then adjusts vehicle speed (within a set range) to ensure that there is a safe distance between vehicles. By using a forward-facing camera and millimeter-wave radar to monitor vehicles merging into or out of the lane, Radar Cruise Control helps maintain smooth acceleration and deceleration while driving.
Toyota believes that the ultimate goal of a society that values mobility is to eliminate traffic fatalities and injuries. Toyota’s Integrated Safety Management Concept sets the direction for safety technology development and vehicle development, and covers all aspects of driving by integrating individual vehicle safety technologies and systems rather than viewing them as independently functioning units. This approach is reflected in R&D focusing on safety devices and systems.
Toyota is firmly committed to a wide range of initiatives addressing traffic safety, ranging from the development of ever-safer vehicles and technologies to helping create a safe traffic environment and engaging in educational activities.
