Automobile anti-theft device

摘要

The anti-theft device has a security control device (11) for operating a vehicle disabling device and/or an alarm and coupled to a car telephone for automatic transmission of an emergency signal via the radio telephone network when an unauthorised attempt is made to remove the vehicle. The security control device provides a blocking signal for the car telephone when the vehicle is at a standstill and the anti-theft device is switched into operation, to prevent reception of an incoming call.
