Abstract

An operating device for a vehicle with an automated transmission and an electrically actuated parking brake system. The device includes a mechanical actuating element for inputting operating commands from the user and a control unit for converting the operating commands into control signals for the transmission and the parking brake system. The actuating element has at least first and second successive stable positions, a neutral position and a return position. In the first stable position, an operating command is generated for the parking brake system to actuate the parking brake device and, in the second stable position, an operating command is generated for the transmission to actuate the parking lock device. The actuating element combines two different actuating elements into an operating device which enables the driver to choose whether, besides activation of the parking brake system, he wishes to additionally engage the parking lock system associated with the transmission.
