The invention discloses an electric vehicle escape method, device and equipment and a storage medium. The method includes: determining a driving mode of a target electric vehicle; when the driving mode is an out-of-trap mode, the gears, the accelerator pedal opening degree and the current vehicle speed of the target electric vehicle are determined, and the gears comprise the forward gear and the reverse gear; and according to the gear, the accelerator pedal opening degree and the current vehicle speed, the target rotating speed and the target torque limiting value of the driving motor are determined, and the target electric vehicle is controlled to get out of trouble based on the target rotating speed and the target torque limiting value. By determining the target rotating speed and the torque limiting value, the large torque can be continuously and stably output in the escape mode, excessive sliding rotation of wheels is avoided, escape operation of the electric automobile in a specific scene becomes easy, the escape capacity is improved, enough power output is guaranteed, and meanwhile the safety of the electric automobile is improved. Damage to key components such as a driving motor and a differential mechanism due to excessive output is avoided, the service life of the vehicle is prolonged, and the device can adapt to various possible escape scenes.

    本发明公开了一种电动汽车脱困方法、装置、设备及存储介质。包括:确定目标电动汽车的驾驶模式;当驾驶模式为脱困模式时,确定目标电动汽车的挡位、油门踏板开度和当前车速,其中,挡位包括前进挡和后退挡;根据挡位、油门踏板开度以及当前车速确定驱动电机的目标转速和目标扭矩限制值,基于目标转速和目标扭矩限制值控制目标电动汽车脱困。通过确定目标转速和扭矩限制值能够在脱困模式下可以持续稳定输出大扭矩并且不发生车轮过度滑转,让电动汽车在特定场景下的脱困操作变得容易而且提高了脱困能力,在保障足够动力输出的同时,避免因过度输出而对驱动电机、差速器等关键部件造成损坏,延长车辆的使用寿命,能够适应各种可能的脱困场景。
