The invention discloses a vehicle torque control method, device and equipment and a medium, and belongs to the technical field of vehicles. The method comprises the steps that the current speed and the current acceleration of a vehicle are obtained; calculating a target acceleration according to the current vehicle speed; and according to the vehicle speed difference between a preset target vehicle speed and the current vehicle speed and the acceleration difference between the target acceleration and the current acceleration, target torque is determined, and the torque of the vehicle is controlled to be the target torque. According to the method, the vehicle speed deviation condition can be known through the vehicle speed difference between the target vehicle speed and the current vehicle speed, the acceleration deviation condition can be known through the acceleration difference between the target acceleration and the current acceleration, the final torque of the vehicle is jointly determined according to the vehicle speed deviation and the acceleration deviation, the nodding phenomenon in the parking process is eliminated, and the dizziness feeling is reduced; and user experience is improved.

    本发明公开了一种车辆扭矩的控制方法、装置、设备及介质,属于车辆技术领域。该方法包括:获取车辆的当前车速和当前加速度;根据所述当前车速,计算目标加速度;根据预设的目标车速与所述当前车速的车速差,以及所述目标加速度与所述当前加速度的加速度差,确定目标扭矩,并控制所述车辆的扭矩为所述目标扭矩。该方法可以通过目标车速与当前车速的车速差,了解车速偏差情况,以及通过目标加速度与当前加速度的加速度差,了解加速度偏差的情况,根据车速偏差和加速度偏差共同确定最终车辆的扭矩,消除停车过程中的点头现象,减少眩晕感,提升用户体验。
