Abstract

In accordance with various exemplary embodiments, the present disclosure describes methods and systems for detecting steering wheel contact by a user. A test signal may be transmitted to a power assisted steering system of a vehicle, where the test signal may apply torque to the steering wheel of the vehicle. A torque sensor may then receive measurements signals indicative of steering wheel torque. The torque indicated by the measurement signals may be compared to an expected torque. Based on the comparison, it may be determined whether the user is in contact with the steering wheel.
