Abstract
An anti-spin control system for wheeled vehicles having an improved steering angle compensating unit which is preferably in the form of a potentiometer having a resistive element with opposite end terminals connected to a reference potential and an intermediate terminal which is connected to receive the wheel speed signal from its respective wheel speed sensor and which is asymetrically disposed with respect to the end terminals. The potentiometer additionally has a wiping arm which is associated with a vehicle steering member so as to be movable therewith across the resistive element so as to provide a potential at the wiper arm which is determined in accordance with the position of the vehicle steering member and the asymmetrical location of the intermediate terminal. An adjusted wheel speed signal is thus provided at the wiper arm of the potentiometer which initially increases and then decreases in accordance with the position of the steering element for turns in one direction. In this manner, the speed signals of the steerable wheels of the vehicle are compensated for changes in turning radius due to changes in steering angle. Alternative embodiments which utilize the steering angle compensation unit to adjust other signals in the circuit to accomplish the same result are also disclosed.
