Toyota Motor Corp. used statistics from the Institute for Traffic Accident Research and Data Analysis to target development of its next-generation collision avoidance system. More than 90% of rear-end collisions happen when the difference in speed between the two vehicles is within 37 miles per hour. This is the typical scenario during high-speed collisions – not necessarily a car being rear-ended out of nowhere at 70 mph, but more like the typical traffic conditions of another driver trying pass up a car in the way without taking realistic stopping maneuvers.
Toyota has developed a high-speed collision avoidance system along with a new testing facility in Japan to increase pedestrian and vehicle safety technologies, along with fuel-efficiency innovations. Toyota’s Pre-collision System has utilized real world traffic data to improve performance and safety. PCS uses millimeter-wave radar to look ahead for other vehicles, and warns the driver via sound and display alerts to apply the brakes to avoid a potential collision. The system also deploys braking assist and automatic braking. When brakes are applied, PCS can slow the vehicle by as much as around 40 miles per hour when the speed differential between the following vehicle and the vehicle ahead is about 40 mph.
How does it work? Toyota’s PCS applies twice as much braking force as what average drivers capable of doing, and will automatically apply the brakes even if the driver doesn’t under certain conditions. The automaker says PCS was developed for use in a wide variety of its automobiles, starting with soon-to-be-launched models.
