Motor torque correction method and device of electric power steering system, medium and product

The invention discloses an electric power steering system motor torque correction method and device, a medium and a product, and relates to the technical field of automobile motor torque correction.The method comprises the steps that the motor rotor angular speed of an automobile steering motor of a target automobile is obtained, and differential operation is conducted on the motor rotor angular speed to obtain rotor angular acceleration; the final number of tremors is calculated according to the real-time amplitude of the rotor angular acceleration; when the driving state of the target automobile is a normal driving state, determining a reduction assistance coefficient according to the final tremor times; according to the reduced assisting power coefficient and the motor assisting power torque, the corrected assisting power torque is obtained through calculation; the corrected power-assisted torque is used for being input into a steering system so as to eliminate the tremor phenomenon.
