The invention relates to the technical field of vehicle control, in particular to a brake control method for improving the vehicle maneuverability. A vehicle speed and a steering wheel angle signal are obtained, and a hydraulic control unit of the vehicle is started to brake rear inner wheels of the vehicle when the steering wheel angle is larger than a set angle and the vehicle speed is not higher than the set speed; and the speed change conditions of the rear inner wheel and the rear outer wheel of the vehicle after the rear inner wheel is braked are obtained, and the brake force of the rearinner wheel is controlled according to the change conditions. By collecting the rotating speed conditions of the rear inner wheel and the rear outer wheel of the vehicle, the brake force of the rearinner wheel is controlled, so that the purpose of accurately controlling the brake force of the rear inner wheel is achieved, the turning radius of the vehicle is ensured to be reduced, the risk thata front axle slides towards the inner side is not increased, and the driving comfort is improved.

    本发明涉及汽车控制技术领域,具体地指一种提高车辆机动性的制动控制方法。获取汽车车速以及方向盘转角信号,当方向盘转角大于设定转角且车速不高于设定车速时,启动车辆的液压控制单元,对车辆的后内车轮进行制动;获取汽车后内车轮和后外车轮在对后内车轮进行制动后的速度变化情况,根据该变化情况对后内车轮的制动力进行控制。本发明通过采集汽车后内车轮和后外车轮的转速情况,对后内车轮的制动力大小进行控制,以达到精确控制后内车轮制动力大小的目的,确保减小汽车的转弯半径,并且不会增加前桥向内侧滑移的风险,提高了驾驶舒适性。
