The invention relates to a torque control method and device, electronic equipment, a vehicle and a storage medium, and relates to the field of new energy vehicles, and the method comprises the steps that under the condition that an electronic hydraulic braking (EHB) system of the vehicle is in an activated state and the vehicle starts to quit energy recovery, the torque control right of the EHB system on a motor of the vehicle is kept, and the motor of the vehicle is started to quit energy recovery; the method comprises the following steps of: acquiring a VCU request torque indicated by a vehicle controller VCU of a vehicle, adjusting the EHB torque of the EHB system according to a set rate by taking the VCU request torque as a target value, and transferring the torque control right of the motor to the VCU from the EHB system under the condition that the EHB torque is greater than or equal to the VCU request torque. And when the vehicle quits energy recovery, through a torque return control strategy, stable switching of torque control is achieved, motor fluctuation in the switching process is reduced, and the problem that the whole vehicle shakes is avoided.

    本公开涉及一种扭矩控制方法、装置、电子设备、车辆及存储介质,涉及新能源车辆领域,该方法包括:在该车辆的电子液压制动EHB系统处于激活状态,且该车辆开始退出能量回收的情况下,保持该EHB系统对该车辆的电机的扭矩控制权,并获取该车辆的车辆控制器VCU指示的VCU请求扭矩,再以该VCU请求扭矩为目标值,按照设定速率对该EHB系统的EHB扭矩进行调节,在该EHB扭矩大于或等于该VCU请求扭矩的情况下,将该电机的扭矩控制权由该EHB系统移交至该VCU。在车辆退出能量回收时通过扭矩归还的控制策略,实现扭矩控制平稳切换,减小切换过程中的电机波动,避免产生整车抖动的问题。
