훨속 신호를 이용한 급제동 경보 시스템 개발

Automotive manufactures keep trying to make more safe vehicles to reduce accident using pre-crash warning system. One of pre-crash prevention and crash mitigation methods is ESS system which is alert device to following vehicle. The Emergency Stop Signal function is warning hazard situation to the following vehicles using rapid flashing brake lamps or hazard lamps when the vehicle get into emergency stopping. The controller operation is determinate by vehicle longitudinal deceleration. To operate system, the deceleration is estimated using wheel speed and, which is not necessary an acceleration sensor from idea using TRIZ method, and the control logic is integrated to ABS (Anti-lock Brake System) or ESP(Electric Stability Program). The optimized control logic is tested with the cooperation under HMC leading. And the system is applied to the controllers of mass production vehicles.
