摘要： A system and method for providing TCC control and/or transmission gear shift control by considering the rate of change of the accelerator pedal or throttle position. The method determines whether the rate of change of the throttle position exceeds a predetermined positive rate of change or a predetermined negative rate of change and, if so, releases the TCC to provide TCC control. Alternatively, or additionally, the method can provide a transmission gear down-shift or up-shift depending on which direction the throttle position is changing. Once the TCC and/or gear shift control has been initiated, the method can start a timer and then return to normal TCC and/or gear shift control after the timer has expired. The TCC and/or gear shift control can also return to normal if the rate of change of the throttle position indicates that the throttle is being returned to its previous position.
