The invention discloses an electric vehicle control method and device, an electric vehicle and a storage medium, and the electric vehicle control method comprises the steps that parking information of the electric vehicle is obtained; when it is determined that the electric vehicle is in a parking starting state according to the parking information, target torque of a driving motor of the electric vehicle is determined, the parking starting state is used for representing that the driving motor of the electric vehicle is in a torque zero-crossing state, and the target torque is smaller than preset zero-crossing torque; the preset zero-crossing torque is used for representing a torque threshold value that the driving motor generates jerking in a parking starting state; and controlling the electric vehicle to park according to the target torque. According to the method, when the electric automobile is in the parking starting state, the electric automobile is controlled to be parked according to the target torque, pause caused by too fast torque change when the driving motor is in the torque zero-crossing state can be avoided, and the parking stability of the electric automobile in the APA process is improved.

    本申请公开了一种电动汽车控制方法、控制装置、电动汽车及存储介质,电动汽车控制方法,包括:获取电动汽车的泊车信息;当根据泊车信息确定电动汽车处于泊车起步状态时,确定电动汽车的驱动电机的目标扭矩,泊车起步状态用于表征电动汽车的驱动电机处于扭矩过零状态,目标扭矩小于预设过零扭矩,预设过零扭矩用于表征驱动电机在泊车起步状态下产生顿挫的扭矩阈值;根据目标扭矩控制电动汽车进行泊车。本方法实现了在电动汽车处于泊车起步状态时,根据目标扭矩控制电动汽车进行泊车,可避免驱动电机处于扭矩过零状态时因扭矩变化太快产生顿挫,增加了电动汽车在APA过程中的泊车稳定性。
