FIELD: machine building.
SUBSTANCE: proposed device for undamaged safe locking of vehicle engine. Locking device comprises vehicle controller (1), engine parameter sensor (3) equipped with connector and connected to controller (1) by means of wire harness, and interlocking module (4) installed in wire harness break between controller (1) and connector (2) of sensor (3) connection. Locking module (4) is configured to distort parameters of signal transmitted from sensor (3) so that engine operation becomes impossible. Locking module (4) comprises current-measuring element (5) installed with possibility of measuring current flowing in sensor (3) supply circuits, and switching device (6) configured to connect load simulator (7) of sensor (3) upon disconnection thereof. Locking module (4) can be controlled wireline or wirelessly.
EFFECT: higher safety is achieved.
