Motor vehicle security system has evaluation and control system to operate mechanical clamping actuator in keyless go mode

摘要

The vehicle use authorisation system operates in a key or keyless mode, with an electronic ignition immobiliser (10), a vehicle bus system (50,52) and an evaluating and control (30) receiving data from the immobiliser via the bus. The evaluation and control evaluates the operating condition of a mechanical actuator (22) to selectively actuate the actuator for operating a clamping system in the keyless go mode.
