A method and system of detecting power hop of a vehicle involves generating signals, including a current signal and a previous signal, indicative of the current longitudinal acceleration of the vehicle, calculating the period and amplitude of the signals, determining if the combined period and amplitude of the current signal exceeds a first predetermined value, and determining whether the combined period and amplitude of the current signal exceeds a second predetermined value greater than the first predetermined value. The method may also involve determining if the amplitude of the current signal exceeds a predetermined percentage of the amplitude of the previous signal. Power hop is detected when the combined period and amplitude of the current signal exceeds the first predetermined value as well as the second predetermined value, and possibly also when the amplitude of the current signal exceeds the predetermined percentage of the amplitude of the previous signal.
