The invention relates to a vehicle active safety control method and device and a vehicle. The device includes a memory and a processor, the processor is to execute instructions stored in the memory bycalculating estimated collision time of a running vehicle and a target object in front of the running vehicle, and judging whether the estimated collision time is less than a set first collision timethreshold value or not, if YES, entering an active safety mode, calculating the motor feedback torque, and performing braking according to the calculated motor feedback torque. The situation that thebraking force is not matched with the current vehicle running speed is avoided, and the problem that the braking feeling is poor due to the fact that the running braking force is not matched with thevehicle speed when an existing vehicle conducts active safety control is solved.

    本发明涉及了一种车辆主动安全控制方法及装置、车辆,装置包括存储器和处理器,处理器用于执行存储在存储器中的指令以实现如下方法:计算行驶车辆与该行驶车辆前端目标物的预计碰撞时间,并判断预计碰撞时间是否小于设定第一碰撞时间阈值:若碰撞时间小于设定第一碰撞时间阈值,则进入主动安全模式:计算电机回馈转矩,根据计算出的电机回馈转矩来进行制动。避免了制动力与当前车辆行驶速度不匹配的情况,解决了现有车辆在进行主动安全控制时行车制动力与车辆速度不匹配而造成的制动感受较差的问题。
