Toyota City, Japan, —Toyota Motor Corporation announced that it has developed a Pre-collision System (PCS) with collision avoidance assist that is effective in helping mitigate high-speed collisions.
The newly developed PCS uses millimeter-wave radar to detect the risk of a rear-end collision with a preceding vehicle, with the system warning the driver via sound and display alerts to prompt braking when such a risk is detected. When the driver applies the brakes, PCS enables a reduction in speed of up to 60 km/h by greatly increasing the braking force up to twice that of the average force applied by drivers. If the brakes are not applied, automatic reduction in speed of 15 km/h to approximately 30 km/h is possible.
More than 90 per cent of rear-end collisions occur when the difference in speed between the preceding and following vehicle is within 60 km/h. TMC aimed to develop a system based on real-world collision data, and has, with its newly developed system, achieved rear-end-collision reducing-effects at the highest level in the industry. The new PCS was developed to be used in a wide variety of models, and is to be rolled out starting with soon-to-be-launched models.
To contribute to the elimination of traffic accident fatalities and injuries—the ultimate goal of a society that values mobility—TMC is conducting research and development on individual onboard safety devices and systems based on its Integrated Safety Management Concept, an approach that gives direction to safety technology and vehicle development. TMC is pressing forward with the development of safer vehicles and technologies and is intensifying its wide-ranging traffic-safety initiatives by participating in the development of traffic environments and conducting educational traffic-safety activities.
