CONTROL SYSTEM AND METHOD FOR BREAKING VEHICLE CONSIDERING RESPONSE-PREFORMANCE OF BRAKE

摘要

The vehicle brake control system for a brake response performance according to an embodiment of the present disclosure includes a sensing unit which has a front detection sensor detecting a front object with respect to a vehicle and a vehicle speed sensor detecting a relative velocity or an absolute velocity of the vehicle with respect to the front object; a driver operating unit which has a brake reaction velocity set unit determining a brake response velocity of the vehicle and a before-crash residual distance set unit determining a distance between the vehicle and the front object when the vehicle stops; a control unit which calculates the crash risk percentage of the vehicle by using sensing value of the sensing unit; a brake unit which allows the vehicle braking according to the crash risk percentage calculated from the control unit. The brake unit adjusts a time for putting the brake on the vehicle according to a brake response velocity set in the brake reaction velocity set unit. It is possible to determine the crash risk percentage of the front object and the vehicle through the distance between the front object and the vehicle and the vehicle speed, and to put the brake on the vehicle by considering a demand deceleration designed by a designer and brake performance when the crash risk percentage is high.
