CIRCUIT ARRANGEMENT FOR MONITORING A VEHICLE SECURITY DEVICE

摘要

The invention relates to a circuit arrangement, for monitoring a vehicle security device (10), comprising a controller (12), embodied for controlling the security device (10), dependent on at least one input signal (52, 54, 56, 58) and a monitoring unit (18), embodied for checking the controller (12). According to the invention, the monitoring unit (18) is also embodied for controlling the security device (10), dependent on at least one input signal (52, 54, 56, 58) and, furthermore, activating means (26, 28, 30, 32) are provided, for activating at least one actuator (40, 42, 44, 46, 48, 50) on the security device (10), depending on a connection of at least one control signal from the controller (12) and at least one control signal from the monitoring unit (18).
