Abstract
A method and apparatus for rapidly detecting acceleration variations in a moving object by monitoring the instantaneous velocity of the object. A signal representative of instantaneous velocity is operated on to derive signals representative of average acceleration, instantaneous acceleration and predicted velocity. The average acceleration and instantaneous acceleration signals are compared to determine acceleration changes. In a preferred embodiment the invention is applied as a wheel slip/slide detector in a traction vehicle and a signal generated when the instantaneous acceleration deviates from the average acceleration by a predetermined magnitude is utilized as a wheel slip/slide signal to implement corrective action to the power control system of the vehicle. Upon generation of the wheel slip/slide signal, calculation of average acceleration is inhibited to prevent its influence by the sudden acceleration change. The predicted velocity signal, which is dependent upon the average acceleration signal, is compared with the instantaneous velocity signal to determine when the vehicle has recovered from the wheel slip/slide condition.
