Toyota has announced that it has developed a Pre-collision System (PCS) with collision avoidance assist that is effective in helping prevent even 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 deceleration of up to 37 mph 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 9 mph to approximately 18 mph is possible.
Toyota's research shows that more than 90 percent of rear-end collisions occur when the difference in speed between the preceding and following vehicle is within 18 mph. Toyota 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.
