Anti-theft system for a motor vehicle

摘要

The system ( 10 ) comprises a control unit ( 20 ) used for selectively arming and disarming the system ( 10 ), and at least one actuator unit ( 30 ) which is remotely located within the vehicle with reference to the control unit ( 20 ). The actuator unit ( 30 ) comprises an actuator ( 32 ) capable of selectively enabling and disabling operation of a component of the vehicle required for normal operation thereof. Command signals are transmitted from the control unit ( 20 ) to the actuator unit ( 30 ) through air or in existing wires of the vehicle, thereby not requiring external wiring between them. The system ( 10 ) may further comprise a towing sensor unit ( 40 ) and an alarm unit ( 50 ). The system ( 10 ) reduces difficulties and disadvantages of the prior art by providing an anti-theft system where various units can be easily hidden throughout the vehicle.
