Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce generation of jackknifing, lateral swing out, spinning out and the like by computing each parameter, each condition estimation quantity, each reference model from each signal measured in a tractor and feeding a hitch angle and hitch angle rate to a controller together with each signal. SOLUTION: On the basis of an appropriate reference model of a vehicle combination, stable torque for a tractor unit is computed, and this computing is operated at an actual time by means of an on-vehicle computer, and information is collected only from the tractor unit. For example, on the basis of information about a pneumatic pressure of a brake cylinder, a pressure difference in respective rear axle air bags, a steering angle, a yawing rate, lateral acceleration, and wheel speed (in a tractor) and the appropriate model, a hitch angle and its derived function are evaluated. By means of one side braking of rear axles of the tractor, a stabilizing action works for behavior in the hitch point also in the towed unit.
