The invention provides a vehicle control method and device, electronic equipment and a vehicle, and the method comprises the steps: obtaining the rotating speed of a vehicle driving motor and the current request torque, and providing a data basis for the subsequent judgment of whether the vehicle has a low adhesion phenomenon or not. And determining a motor rotating speed change rate according to the rotating speed of the driving motor, and determining a corresponding preset rotating speed change rate threshold according to the current request torque. And in response to the situation that the motor rotating speed change rate exceeds the preset rotating speed change rate threshold value, current motor rotating speed acceleration is abnormal, and a wheel low adhesion phenomenon can occur after a certain time, determining that the vehicle is in a low adhesion working condition, immediately adjusting the current request torque, improving the response speed of the vehicle out-of-trouble operation, and improving the vehicle out-of-trouble operation speed. Therefore, the vehicle can break away from the low-adhesion working condition in time, normal running of the vehicle is prevented from being affected, and the driving safety is improved.
本申请提供一种车辆控制方法、装置、电子设备及车辆,所述方法包括:获取车辆驱动电机的转速和当前请求扭矩,以为后续判断车辆是否出现低附着现象提供数据基础。根据所述驱动电机的转速确定电机转速变化率,根据所述当前请求扭矩确定对应的预设转速变化率阈值。响应于所述电机转速变化率超过所述预设转速变化率阈值,表征当前的电机转速增速异常,在一定时间后会出现车轮低附着现象,则确定所述车辆处于低附着工况,立即对当前请求扭矩进行调整,提升车辆脱困操作的响应速度,以使所述车辆及时脱离低附着工况,避免影响车辆的正常行驶,提升驾驶安全性。
