The invention discloses a control method for avoiding vehicle braking scream, which comprises the following steps of: presetting a speed interval of vehicle driving, and controlling the vehicle to brake in the speed interval; a braking pressure control interval and an SP curve algorithm of a braking controller are preset; in the pressure control interval, through control of a brake controller, front and rear shaft brake pressure is automatically distributed, and front and rear shaft pressure differential brake control is carried out; executing pressure control according to an SP curve algorithm preset by the brake controller when the brake controller is out of the pressure control interval; according to the brake torque equivalence principle, the brake pressure of the front and rear shafts can be automatically distributed, the pressure interval where brake noise is likely to be generated is avoided by conducting pressure differential brake control on the front and rear shafts, and the brake comfort of the vehicle is improved.
本发明公开了一种避免车辆制动尖叫的控制方法,包括预设车辆行驶的速度区间,控制车辆在所述速度区间制动;预设制动的压力控制区间以及制动控制器的SP曲线算法;在压力控制区间内时,通过制动控制器的控制,自动分配前后轴制动压力,进行前后轴压力差动制动控制;在压力控制区间外时,按照所述制动控制器预设的SP曲线算法执行压力控制;本发明可以根据制动力矩等效原则,自动分配前后轴制动压力,并通过对前后轴进行压力差动制动控制避开容易产生制动噪声的压力区间,提升车辆的制动舒适性。
