The invention relates to a vehicle slope parking control method and device, a new energy vehicle and a storage medium. The method comprises the steps that under the condition that a motor hill-holding function of a vehicle is activated, a hill-holding torque initial value and a hill-holding torque dynamic value corresponding to a vehicle motor are determined; determining a slope-holding torque correction value based on the slope-holding torque initial value and the slope-holding torque dynamic value; the recorded clamping torque of the vehicle in the slope parking process is obtained, and a slope parking torque target value is determined based on the clamping torque and the slope parking torque correction value; and controlling a vehicle motor based on the hill-holding torque target value so that the vehicle is held on the slope. By means of the method, more accurate vehicle slope parking can be achieved, slope parking failure caused by the fact that the slope parking torque target value is too large or too small is avoided, and then driving safety is guaranteed.

    本申请涉及一种车辆驻坡控制方法、装置、新能源汽车和存储介质。该方法包括:在车辆的电机驻坡功能激活的情况下,确定车辆电机对应的驻坡扭矩初始值和驻坡扭矩动态值;基于驻坡扭矩初始值和驻坡扭矩动态值,确定驻坡扭矩修正值;获取针对车辆已记录的驻坡过程中的夹紧力矩,并基于夹紧力矩和驻坡扭矩修正值,确定驻坡扭矩目标值;基于驻坡扭矩目标值控制车辆电机,以使车辆驻坡。采用本方法能够实现更为精准的车辆驻坡、避免因驻坡扭矩目标值过大或过小而导致驻坡失败,进而保证驾驶安全。
