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 is determined, and a vehicle motor is controlled based on the hill-holding torque initial value so that the vehicle can decelerate and hold a slope; in the deceleration hill-holding process, the vehicle speed change rate of the vehicle is obtained, and the corresponding torque variable quantity and the corresponding torque gradient are obtained based on the vehicle speed change rate; correcting the slope-holding torque initial value based on the torque gradient and the torque variation to obtain at least one slope-holding torque target value; and the torque output of the vehicle motor is adjusted to the slope parking torque target value so that the vehicle can be parked on the slope. The method can improve the accuracy of the vehicle parking on the slope and ensure the driving safety.
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。所述方法包括:在车辆的电机驻坡功能激活的情况下,确定驻坡扭矩初始值,并基于驻坡扭矩初始值控制车辆电机,以使车辆减速驻坡;在减速驻坡过程中,获取车辆的车速变化率,并基于车速变化率获取对应的扭矩变化量和对应的扭矩梯度;基于扭矩梯度和扭矩变化量修正驻坡扭矩初始值,得到至少一个驻坡扭矩目标值;调整车辆电机的扭矩输出至驻坡扭矩目标值,以使车辆驻坡。采用本方法能够提高车辆驻坡的准确性、保证驾驶安全。
