ABSTRACT:
The control apparatus eliminates the adverse effects upon a moving vehicle caused by interference between two control operations taking place at the same time. For example, the control of torque applied to the wheels simultaneously subjected to wheel slip control can cause competing contradictory instructions to be issued to control the rotation of the wheel. When a wheel undergoing slip control is instructed by the torque split control to increase torque, the torque split control is cancelled. When the torque split control decreases the torque applied to a wheel and the wheel continues to slip, the wheel is subjected to slip control and the torque applied is reduced to prevent slip. When a wheel undergoing slip control has increased torque applied, the slip of the wheel is monitored and the torque is reudced to bring the slip below a predetermined limit.
