Toyota Collision Avoidance Assist System
Toyota Motor Corporation (TMC) announces that it has developed a Pre-collision System (PCS) with collision avoidance assist that is effective in helping mitigate even high-speed collisions. Research has shown that a speed of 40 km/h to 60 km/h at the time of a rear-end collision is the range in which the number of fatal and injury-causing accidents increases.
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 deceleration of up to 60 km/h (when the driver’s car is traveling at 80 km/h and the preceding car is traveling at 20 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 deceleration of 15 km/h to approximately 30 km/h (when the driver’s car is traveling at 50 km/h and the preceding car is traveling at 20 km/h) is possible.
More than 90 percent of rear-end collisions occur when the difference in speed between the preceding and following vehicle is within 60 km/h (preliminary calculations from traffic accident statistics from the Institute for Traffic Accident Research and Data Analysis – ITARDA). 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.
