Abstract
A method hands-on-wheel detection includes receiving a handwheel angle signal from a sensor associated with a handwheel of a vehicle and generating, based on a handwheel angle indicated by the handwheel angle signal, a handwheel speed signal and a handwheel acceleration signal. The method also includes synchronizing the handwheel speed signal and the handwheel acceleration signal by generating a delayed handwheel speed signal and a delayed handwheel acceleration signal. The method also includes generating an operator torque estimation signal based on, at least, the delayed handwheel speed signal and the delayed handwheel acceleration signal. The method also includes determining whether hands of an operator of the vehicle are on the handwheel based on the operator torque estimation signal.
