Steering wheel with key elements for operating electrically controlled devices in a motor vehicle uses piezoelectric pressure sensors acting as key elements.

摘要

Piezoelectric pressure sensors (3,5,6) act as key elements. One part of the pressure sensors (5,6) is located in an activating area, while the other sensors (3) form a control area that is distinctly set apart from the activating area. Activating the pressure sensors (5,6) in the activating area assigns different control functions to the pressure sensors (3) in the control area.
