Abstract
To control the turning direction of a vehicle having wheels with fixed axles or tracks at the respective sides of the vehicle, a steering wheel (1) is coupled to a wheel position transducer (11); a direction control lever (2) is coupled to a position transducer (12), providing forward and reverse (F-REV) driving direction signals. The signals are so arranged that, for turning in respectively opposite directions, signals of positive or negative polarity, with a level varying with the turning radius, are provided; for forward or reverse, respectively, signals of varying polarity are provided. The turning direction signal and the driving direction signal are processed including addition and subtraction, to control independent drive motors (4, 6; 5, 7) at the respective right and left (R-L) sides of the vehicle such that the motor at the inside of the curve will receive a signal which has a lesser algebraic value than the driving direction signal, and the motor at the outside of the curve will receive only the driving direction signal, to cause the wheel at the inside of the curve to rotate slower, or with reverse direction of rotation than that at the outside of the turning circle.
