The invention discloses a vehicle speed determination method and device, equipment and a storage medium, and the method comprises the steps: obtaining a driving mode of a vehicle when the vehicle speed of an anti-lock braking system (ABS) is determined to be incredible, the driving mode comprising only driving of a rear motor controller or simultaneous driving of the rear motor controller and a front motor controller; acquiring the running state of the motor controller in the driving mode, and determining a target motor controller according to the running state; and the rotating speed of a motor associated with the target motor controller is obtained, and the vehicle speed is determined according to the rotating speed. When the ABS speed is determined to be incredible, the target motor controller is determined through the driving mode of the vehicle, and the vehicle speed is calculated according to the motor rotating speed associated with the target motor controller, so that even if the ABS speed is determined to be incredible, replacement can be performed based on the vehicle speed calculated based on the accurate motor rotating speed; therefore, the accuracy of the vehicle speed is ensured, and the driving safety is improved.

    本发明公开了一种车辆速度的确定方法、装置、设备及存储介质,包括:当确定防抱死制动系统ABS车速不可信时,获取车辆的驱动模式,其中,驱动模式包括仅后电机控制器驱动或者后电机控制器和前电机控制器同时驱动;在驱动模式下获取电机控制器的运行状态,并根据运行状态确定出目标电机控制器;获取目标电机控制器所关联的电机的转速,并根据转速确定车辆速度。当确定ABS车速不可信的情况下,通过车辆的驱动模式确定出目标电机控制器,并根据目标电机控制器所关联的电机转速计算出车辆速度,从而即使当ABS车速不可信的情况下,也可以基于精准的电机转速所计算的车辆速度进行替换,从而保证车辆速度的准确性,以提高驾驶的安全性。
