Abstract:
1. A method of detecting power hop of a vehicle, comprising: obtaining a plurality of successive signals indicative of a longitudinal acceleration of the vehicle, including a current signal and a preceding signal that precedes the current signal, the vehicle including an engine connected to an electronic control unit, the electronic control unit controlling engine torque produced by the engine; calculating a period and an amplitude of the successive signals; determining if a combination of the period and amplitude of each of the successive signals exceeds a first predetermined value; determining if the combination of the period and amplitude of the current signal exceeds a second predetermined value that is greater than the first predetermined value; determining existence of a power hop condition when both the combination of the period and amplitude of the current signal exceeds the first predetermined value, and the combination of the period and amplitude of the current signal exceeds the second predetermined value; and reducing the engine torque of the engine through control by the electronic control unit when the power hop condition is determined to exist.
