The invention discloses a vehicle acceleration method, device and system and a storage medium. The vehicle acceleration method, device and system are used for shortening the acceleration time of a vehicle in a deceleration state. The method comprises the following steps: monitoring the driving environment of a vehicle in the driving process of the vehicle; whether the vehicle needs to be accelerated or not is judged according to the driving environment of the vehicle; when the vehicle needs to be accelerated and the vehicle is currently in a deceleration state, a brake master cylinder pressure pump is controlled to rotate reversely so as to release the pressure of the master cylinder pressure pump, and the reverse rotation speed of the master cylinder pressure pump can meet the requirement that the pressure of a brake master cylinder is released to be zero before the wheel end torque of the vehicle is adjusted to be in the forward direction. By adopting the scheme provided by the invention, the pressure of the brake master cylinder is released to be 0 before the torque of the wheel end of the vehicle becomes a positive value, so that the acceleration rate is increased, and the acceleration time is shortened.

    本申请公开了一种车辆加速方法、装置、系统及存储介质,用以缩短车辆在减速状态情况下的加速时间。所述方法包括:在车辆行驶过程中,监测车辆的行驶环境;根据所述车辆的行驶环境判断所述车辆是否需要加速;当所述车辆需要加速且车辆当前处于减速状态时,控制制动主缸压力泵进行反转以释放主缸压力泵的压力,其中,所述主缸压力泵的反转速度能够满足在车辆的轮端扭矩调整为正向之前将制动主缸的压力释放为0。采用本申请所提供的方案,在车辆轮端扭矩变为正值之前将制动主缸压力释放为0,进而提高了加速速率,缩短了加速时间。
