Motor vehicle steering wheel, has conducting surface on steering wheel in common with driver's hand contact surface to form capacitor with wheel cover forming dielectric

摘要

The steering wheel (10) has a measurement arrangement for detecting contact of driver's (13) hand on the steering wheel and an evaluation circuit that controls at least one vehicle-specific device. A conducting surface is arranged on the steering wheel common with the driver's hand contact surface on the wheel to form a capacitor (14), using wheel cover to form the dielectric. A measurement signal is derived from the change in capacitance when the driver places his hand on the wheel.
