The embodiment of the invention discloses a torque dragging control exit method and device, electronic equipment and a storage medium. The method comprises the steps that the current vehicle speed and the current wheel speed of a controlled vehicle are obtained, and the current slippage amount of the controlled vehicle is determined based on the vehicle speed and the wheel speed; under the condition that the current slip amount is smaller than a preset torque dragging control exit threshold, the proportional control amount and the integral control amount of feedback control are determined based on the current slip amount, the slip amount of the last cycle and the preset target slip amount; and a torque request is determined according to the proportional control quantity and the integral control quantity, and the torque request is sent to an electric control system of the controlled vehicle so as to control the vehicle slip amount in the torque dragging control quit process. On the basis, closed-loop feedback control is achieved by means of the slip amount under the condition that torque dragging quit needs to be conducted, it is guaranteed that in the torque dragging control quit process, the slip amount of the vehicle is controlled to be in a stable state, and the stability of the vehicle is improved.
本申请实施例公开了一种扭矩拖拽控制退出方法、装置、电子设备及存储介质。该方法包括:获取受控车辆当前的车速和轮速,并基于车速和轮速确定受控车辆当前的滑移量;在当前的滑移量小于预设的扭矩拖拽控制退出门限的情况下,基于当前的滑移量、上一循环的滑移量、预设目标滑移量确定反馈控制的比例控制量和积分控制量;根据比例控制量和积分控制量确定扭矩请求,并将扭矩请求发送给受控车辆的电控系统,以控制扭矩拖拽控制退出过程中的车辆滑移量。基于此,本申请利用滑移量,在需要进行扭矩拖拽退出的情况下,实现闭环的反馈控制,保证,在扭矩拖拽控制退出过程中,控制车辆的滑移量处于稳定的状态,提高车辆的稳定性。
