The invention relates to the technical field of vehicle emergency braking auxiliary control, in particular to a vehicle snowfield scene emergency braking auxiliary control system and method. According to the control system, through cooperation of an input signal processing module, a collision early warning module, a braking feedback processing module, a snub braking module and an output signal processing module, the emergency braking performance of a vehicle on a low-adhesion road surface can be effectively improved, and tires are prevented from being locked and slipping; according to the control method, the friction factor of a current road is calculated according to the braking deceleration response condition of the vehicle after snub braking early warning, the snub braking opportunity and the braking factor of the vehicle are determined according to the friction factor, and finally snub braking deceleration control and snub braking interval time control are executed according to the braking factor and the friction factor. Accuracy and control efficiency of vehicle emergency braking auxiliary control can be effectively improved, the sideslip instability phenomenon caused by emergency braking is prevented, and it is guaranteed that the vehicle is braked and stopped in time to avoid collision.

    本发明涉及车辆紧急制动辅助控制技术领域,具体涉及一种车辆雪地场景紧急制动辅助控制系统及控制方法。所述控制系统通过输入信号处理模块、碰撞预警模块、制动反馈处理模块、点刹制动模块和输出信号处理模块相配合,能够有效提升车辆在低附路面的紧急制动性能,防止轮胎抱死打滑;所述控制方法,通过点刹预警后车辆的制动减速响应情况计算当前道路的摩擦因子,并根据摩擦因子确定车辆点刹制动时机和制动因子,最后根据制动因子和摩擦因子执行点刹制动减速度控制和点刹间隔时间控制,能够有效提高车辆紧急制动辅助控制的准确性和控制效率,防止因紧急制动而导致的侧滑失稳现象,并保证车辆及时刹停避撞。
