Actuation device for electromechanical functional unit in external force-operated parking brake system of motor vehicle, has locking unit holding control element after actuation in tension-free condition of device in space position

摘要

#CMT# #/CMT# The device has a control element (12) manually operated by a driver of a motor vehicle, an electronic controller (30) and a locking unit (22) that is controlled by the electronic controller. The locking unit holds the control element after actuation in the tension-free condition of the device in a space position based on the detection of the momentary actuation condition of an electromechanical functional unit (34). The locking unit holds the control element in a maximum position and in an intermediate position. #CMT#USE : #/CMT# Actuation device for an electromechanical functional unit in an external force-operated parking brake system of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The locking unit allows actuation of the control element in spatial direction in case of determined malfunctioning of actuation device, thus allowing the actuation device to improve the working reliability of the motor vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of an actuation device for an electronically controllable functional unit. 12 : Control element 18 : Handle 22 : Locking unit 30 : Electronic controller 34 : Electromechanical functional unit.
