ABSTRACT:
A system for correctively controlling the turning movement of a vehicle, including a device for correcting the turning movement of the vehicle, a sensor for detecting the steering angle of a steering wheel of the vehicle, a steering angle hysteresis storage device for storing the hysteresis of the steering angle, and a reference value arithmetic device for determining a reference value of a physical quantity generated during a turning movement of the vehicle, on the basis of the hysteresis of the steering angle. The system also includes a detector for detecting an actual value of the physical quantity during the turning movement, a calculator for determining a deviation between the reference value and actual value of the physical quantity and a polarity of the deviation, and a control-quantity determining device for determining a control-quantity for the turning movement correcting device on the basis of the deviation obtained in the calculator. A device is included for determining a control-direction of correction of the turning movement on the basis of the polarity of the deviation. This system permits the turning movement of the vehicle to be automatically corrected.
