Toyota has revealed some of the smart new technologies and systems it will be featuring in future models to make driving safer.
To be integrated in the company’s Integrated Safety Management Concept, Toyota said these have been designed from the start to work together to help cut the number of road accidents.
The new features were announced at a safety seminar in Toyota City and will be rolled out in new models starting in 2015.
Toyota added it 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.
All these new technologies can be found under three umbrellas: Vehicle-infrastructure (V2X) and vehicle-vehicle communications (V2V), LED Array Adaptive High Beam and Toyota active safety packages.
V2X and V2V communications
Driving up to a blind junction, even the best on-board cameras and sensors can’t always give you clear warning of the potential hazards.
Toyota explained it 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, arriving 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.
Of course, this will work well only when and if the proper sensor infrastructure is set in place.
Toyota added it 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. The new system uses a forward-facing millimeter-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. According to Toyota, this significantly improves tracking performance in traffic, being safer and more fuel-efficient, and helping avoid one of the common causes of congestion.
Toyota added it developed 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 claims its next-generation automatic high beam and adaptive lighting system is ready to deliver even better night-time illumination. The company calls the new system the LED Array Adaptive High Beam.
Toyota explained this system uses multiple, independently controlled LEDs arranged in a single row, giving 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 active safety packages
For 2015, Toyota stated it will launch a new set of active safety technologies design to help prevent or mitigate collisions across a wide range of vehicle speeds. Per Toyota, they will be offered in two Toyota Safety Sense packages, initially in Japan and subsequently in the U.S. and Europe, by the end of 2017.
The two packages – designated C and P for mid-size and larger vehicles respectively – are said to 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 millimeter-wave radar, each combined with a camera.
Toyota added a separate active safety package, to be called Lexus Safety System+, will be marketed for Lexus models, including a new Road Sign Assist function.
This last function will recognize speed limits and road signs, at home and when traveling overseas, presenting the information on the driver’s instrument display.
