<p>A vehicle immobilisation system has an electronically controlled locking mechanism (10) which requires an electrical supply to be switched between a locked state and an unlocked state, the locking mechanism (10) remaining in the state to which it is switched when disconnected from the electrical supply. The immobilisation system includes control means (30,32,40) which operates to connect the locking mechanism (10) to the electrical supply to switch it from one state to the other, and to disconnect the locking mechanism (10) from the electrical supply when the vehicle engine is running or the vehicle is moving. The immobilisation system also including means (40) to prevent cranking of the engine when the locking mechanism (10) is in it's locked state. <IMAGE></p> |
