The invention relates to a collision protection method and device, electronic equipment, a storage medium and a vehicle, and relates to the technical field of vehicle control, and the method comprises the steps: obtaining operation parameters and original parameters of the vehicle, the operation parameters comprise an instantaneous vehicle speed, a vehicle acceleration change value and wheel resistance, and the original parameters comprise a vehicle weight; the instantaneous vehicle speed is the vehicle speed detected at the current moment, the vehicle acceleration change value is the acceleration change value corresponding to the instantaneous vehicle speed, the vehicle state is determined according to the vehicle acceleration change value and the vehicle weight, and under the condition that the vehicle state is collision, the target reverse dragging torque is determined according to the instantaneous vehicle speed and the wheel resistance; and the vehicle driving motor is controlled according to the target reverse dragging torque, whether the vehicle is collided or not can be judged according to the vehicle acceleration change value and the vehicle weight, and the corresponding target reverse dragging torque is determined when the vehicle is collided, so that the vehicle speed can be rapidly reduced, and the collision danger of people and objects in the vehicle is reduced.

    本公开涉及一种碰撞防护方法、装置、电子设备、存储介质和车辆,涉及车辆控制技术领域,该方法包括:通过获取车辆的运行参数和原始参数,运行参数包括瞬时车速、车辆加速度变化值和车轮阻力,原始参数包括车辆重量,瞬时车速为当前时刻检测到的车辆的车速,车辆加速度变化值为瞬时车速对应的加速度变化值,并根据车辆加速度变化值和车辆重量,确定车辆状态,在车辆状态为发生碰撞的情况下,根据瞬时车速和车轮阻力,确定目标反拖扭矩,并根据目标反拖扭矩控制车辆驱动电机,能够通过车辆加速度变化值和车辆重量,判别车辆是否发生碰撞,并在车辆发生碰撞时确定对应的目标反拖扭矩,以便能够快速降低车速,降低车内人员及物品的磕碰危险。
