Abstract:
A wheel slip/slide correction system for a vehicle having at least one driven wheel, the system comprising:means for providing a first signal and a second signal representative, respectively, of actual vehicle velocity and vehicle acceleration;means for providing a third and a fourth signal representative, respectively, of measured wheel velocity and wheel acceleration of the at least one driven wheel;means for converting said first and second signals to equivalent wheel velocity and acceleration;means for comparing said equivalent wheel velocity to said measured wheel velocity and for obtaining at least one velocity error signal representative of the difference therebetween;means for comparing said at least one velocity error signal to at least one velocity threshold value and for generating a slip/slide signal when said at least one velocity error signal exceeds said threshold value;means responsive to said slip/slide signal for developing an acceleration error signal representative of any difference between said equivalent wheel acceleration and said measured wheel acceleration; andmeans for applying said acceleration error signal to adjust power to the driven wheel in a manner to reduce said velocity error signal below said threshold value.
