Zusammenfassung: | The invention provides an electric motor car differential steeling control method based on slip rate control. The method comprises the following steps of: (1) measuring the back wheel speed of the electric motor car, the actual output torque of a drive motor and the side speed of the car according to a wheel sped sensor; and (2) calculating the side speed and the heading angle peed of the electric motor car according to two freedom steering models, and then calculating the slip angles of four wheels, thereby calculating the rotational speed of the four wheels; and using a special arithmetic to realize the control on the electric differential steeling of a hub electric motor car. The electric motor car differential steeling control method based on slip rate control combines the calculation of torque distribution with the slip rate of the wheels to lead a designed electric differential steeling mechanism to have the effect of differential lock simultaneously when having the differential and also have the functi |
