Abstract
A system and method for detecting wheel lift of an automotive vehicle includes a yaw rate sensor ( ) that generates a yaw rate signal, a lateral acceleration sensor ( ) that generates a lateral acceleration signal, a roll rate sensor ( ) generating a roll rate signal, and a longitudinal acceleration sensor ( ) for generating a longitudinal acceleration signal. A controller ( ) is coupled to the yaw rate sensor ( ), the lateral acceleration sensor ( ), the roll rate sensor ( ), and the longitudinal acceleration sensor ( ). The controller determines a dynamic load transfer acting on the plurality of wheels as a function of yaw rate, lateral acceleration roll rate, and longitudinal acceleration. Normal forces for each of the plurality of wheels is determined as a function of the dynamic load transfer. Wheel lift is indicated when at least one of the normal forces for each of the plurality of wheels is less than a normal force threshold.
