If the system detects an accident and the driver brakes, but not hard enough to avoid the accident, DBS automatically supplements the driver's braking to avoid an accident. If the system detects an accident but the driver does not brake at all, CIB automatically applies the vehicle's brakes to slow or stop the car, thereby preventing the accident or reducing its severity.
Extensive research into this technology and relevant performance measures has shown that a number of AEB systems currently available on the market are capable of avoiding or reducing the severity of rear-end collisions in certain situations.
