VEHICLE SECURITY DEVICE

摘要

The present application concerns a vehicle security device with particular use in the recovery of a stolen vehicle. In one aspect, the invention is a vehicle key suppressor for inhibiting communication between an electronic start key (including, for example, a conventional coded ignition key as well as an advanced key system, a remote keyless system, and a fingerprint and/or eye recognition system) and an engine control unit ("ECU") in a vehicle comprising a vehicle tracking system. When activated by an activating signal from the tracking system, the suppressor sends an inhibitory signal which inhibits communication between the start key and the EMU, thereby preventing the vehicle engine from being started or restarted.
