The invention discloses a driving control method and device, an electric vehicle, electronic equipment and a storage medium, and the method comprises the steps: determining a first torque limit value corresponding to a first accelerator signal under the condition that the first accelerator signal is received; in response to the first accelerator signal, the rotating speed value of a motor of the vehicle is controlled to be increased to a predetermined first rotating speed target value; in the process that the rotating speed value of the motor is controlled to be increased to the first rotating speed target value, a first output torque value of the vehicle is controlled according to the first torque limiting value, the current rotating speed value of the motor and the first rotating speed target value, and the first output torque value is smaller than or equal to the first torque limiting value. According to the control method, the rotating speed closed loop is performed through the predetermined rotating speed target value, and the torque limit value is determined according to the accelerator signal to limit the output torque value of the vehicle, so that the rotating speed of the motor and the output torque of the motor are effectively controlled, and wheel slipping caused by untimely torque control can be effectively avoided; and the motor overspeed fault is effectively avoided.

    本申请公开了一种驱动控制方法、装置、电动车辆、电子设备及存储介质,其中方法包括:在接收到第一油门信号的情况下,确定第一油门信号对应的第一扭矩限值;响应于第一油门信号,控制车辆的电机的转速值增大至预先确定的第一转速目标值;在控制电机的转速值增大至第一转速目标值的过程中,根据第一扭矩限值、电机的当前转速值和第一转速目标值,控制车辆的第一输出扭矩值,第一输出扭矩值小于或等于第一扭矩限值。本申请中,通过预先确定的转速目标值进行转速闭环,并根据油门信号确定扭矩限值以限制车辆的输出扭矩值,从而对电机的转速和电机输出扭矩进行有效地控制,能够有效避免因扭矩控制不及时而导致车轮打滑,以及有效避免电机超速故障。
