The invention relates to an abrupt slope slow descent control method, system and device, a storage medium and a vehicle control unit. The method comprises the steps that the safe slow descent speed of a vehicle is determined according to the vertical load of each wheel of the vehicle; determining a target braking torque according to the safe slow descent vehicle speed; distributing a front axle braking torque and a rear axle braking torque of the vehicle according to the target braking torque; and distributing the brake torque of each wheel of the vehicle according to the front axle brake torque and the rear axle brake torque. According to the embodiment of the invention, the safe slow descent speed of the vehicle can be determined according to the vertical load of each wheel of the vehicle, and the brake torque of each wheel can be distributed and adjusted according to the safe slow descent speed, so that the method can adapt to complex road conditions with large vertical load changes of the wheels; and the stability and the safety of the vehicle slowly descending on the abrupt slope under the complex road condition are improved.

    本公开涉及一种陡坡缓降控制方法、系统、装置、存储介质及整车控制器,所述方法包括:根据所述车辆的各个车轮的垂直载荷确定所述车辆的安全缓降车速;根据所述安全缓降车速确定目标制动扭矩;根据所述目标制动扭矩分配所述车辆的前轴制动扭矩和后轴制动扭矩;根据所述前轴制动扭矩和所述后轴制动扭矩分配所述车辆各个车轮的制动扭矩。本公开实施例可以根据车辆的各个车轮的垂直载荷确定所述车辆的安全缓降车速,以及根据安全缓降车速分配调整各个车轮的制动扭矩,从而能够适应车轮垂直载荷变化较大的复杂路况,提高车辆在此类复杂路况陡坡缓降的平稳性和安全性。
