Method and device for controlling supporting force of vehicle steering wheel, electronic equipment and medium

The invention provides a control method and device for supporting force of a vehicle steering wheel, electronic equipment and a medium. The method comprises the following steps: acquiring a current steering wheel rotation position corresponding to a current moment of a vehicle and a historical steering wheel rotation position corresponding to a preset historical moment; determining an initial motor torque value of the vehicle at the current moment based on the current steering wheel rotation position and the historical steering wheel rotation position; determining a supporting force steering wheel torque boundary value of the vehicle at the current moment, and performing constraint processing on the initial motor torque value based on the supporting force steering wheel torque boundary value to obtain a motor torque of the vehicle at the current moment; and torque-force conversion processing is conducted on the motor torque based on a preset control algorithm, and the steering wheel supporting force fed back
