Abstract
A sensor system for a steering wheel of a vehicle includes a first sensor disposed within a first portion of the steering wheel to detect contact with a front left surface of the steering wheel. The sensor system includes a second sensor disposed within a second portion of the steering wheel separate from the first portion to detect contact with a front right surface of the steering wheel. The sensor system also includes a third sensor disposed within the steering wheel to detect contact with a rear surface of the steering wheel. The first, second and third sensors are configured to respectively detect touching of the front left surface, the front right, and the rear surface of the steering wheel by a hand or a non-hand part of an operator of the vehicle. The first, second and third sensors can be complex impedance sensors.
