The invention discloses a motor torque control method, device and equipment and a storage medium, and the method comprises the steps: responding to the switching of a gear of a vehicle between a D gear and an R gear, and determining the current initial slope of the current motor request torque according to the current motor request torque and the current slope information of a road where the vehicle is located; determining a current slope correction coefficient according to the current motor request torque and the current vehicle speed; determining a current target slope of the current motor request torque according to the current initial slope and the current slope correction coefficient; and performing motor torque control according to the current motor request torque and the current target slope. Through the technical scheme provided by the invention, the motor request torque can be smoothed under the working condition of switching between the D gear and the R gear, and motor shaking is reduced.

    本申请公开了一种电机转矩控制方法、装置、设备及存储介质,其中,所述方法包括:响应于车辆的档位在D档和R档之间切换,根据当前电机请求转矩和所述车辆所在道路的当前坡度信息,确定所述当前电机请求转矩的当前初始斜率;根据所述当前电机请求转矩和当前车速确定当前斜率修正系数;根据所述当前初始斜率和所述当前斜率修正系数,确定所述当前电机请求转矩的当前目标斜率;根据所述当前电机请求转矩和所述当前目标斜率进行电机转矩控制。通过本申请提供的技术方案能够在D档和R档之间切换的工况下,对电机请求转矩作平滑处理,减少电机抖动。
