The system comprises a unit 10 for mounting in a vehicle and first and second remote control devices 11,21. The vehicle unit 10 comprises a receiver 13 for receiving wireless control signals directly from the remote control devices 11,21 and means 15 for immobilising the vehicle in response thereto. Remote control device 11 transmits a predetermined control signal which is unique to the receiver 13 while remote control device 21 comprises means 16 for selecting the predetermined control signal to be transmitted. In use, remote control device 11 is kept by the vehicle's owner, so that the vehicle can be immobilised each time it is left unattended. Remote control 21 device is kept by the police and in the event of a car theft, the police identify the vehicle, select an appropriate control signal and then transmit the control signal, either from a pursuit vehicle or from the roadside, to immobilise the vehicle. The system is essentially a conventional vehicle immobilisation system with the added facility that it can be activated by the police. Thus the cost of the system is kept low. |
