Safety device for electrically controlled parking brake of e.g. rail-mounted vehicle, has control device controlling safety device and detecting rolling-away of vehicle, when ignition in parked vehicle is switched-off

摘要

The device (10) has sensors (16, 18) e.g. reed-sensors or hall-sensors, for direct detection of a movement of a drive element (20) in a drive train (32). A control device (22) controls the safety device and detects rolling-away of a vehicle (14) when an ignition in the parked vehicle is switched-off. The control device closes a driving brake (24) of the vehicle. The control device deactivates the sensors and performs a monitoring function to monitor the sensors when the vehicle is moved using a drive (28) e.g. internal combustion engine. An independent claim is also included for a method for operating a safety device for an electrically controlled parking brake of a vehicle.
