Passive wheel lift identification for an automotive vehicle using operating input torque to wheel

摘要

A control system ( 18 ) and method for an automotive vehicle ( 10 ) used for detecting lift of a wheel includes a speed sensor ( 20 ) coupled to the wheel producing a wheel speed signal and a torque control system ( 57 ) coupled to the wheel for generating an operating input torque to the wheel. A controller ( 26 ) is coupled to the torque control system ( 57 ) and the wheel speed sensor ( 20 ). The controller ( 26 ) determines a wheel response to the operating input torque and generates a wheel lift signal as a function of the operating input torque, the wheel speed signal and the wheel response.
