Abstract:
A method of controlling torque within a vehicle differential comprising the steps of:providing a differential having first and second output shafts; determining a first speed (&ohgr;a) of said first output shaft; determining a second speed (&ohgr;b) of said second output shaft; determining a target delta (&Dgr;T) as a function of said first speed (&ohgr;a) of said first output shaft and said second speed (&ohgr;b) of said second output shaft under preselected vehicle operating conditions; determining an actual delta (&Dgr;A) as a function of said first speed (&ohgr;a) of said first output shaft and said second speed (&ohgr;b) of said second output shaft under actual vehicle operating conditions; determining a control value (CV) as a function of said actual delta (&Dgr;A) and said target delta (&Dgr;T); and comparing said control value (CV) to said target delta (&Dgr;T).
