FIELD: vehicle security systems.
SUBSTANCE: engine unauthorized start detection system comprises an assembly of electronic modules for immobilization and de-immobilization of cargo vehicles, consisting of electronic interlocking system containing electronic module M, protected by self-destruction system. Module M represents two separate modules - engine speed sensor module M1 and phase sensor module M2, each of which is connected to ECU. Control module R accommodates in its circuit an integrated circuit in a password and counter-password system connected to the vehicle ignition system, in which, in case of replacement of modules M1 and M2 with original sensors of the vehicle, in order to perform fraudulent actions, when the engine is on, such unauthorized start of the engine is recorded by the monitoring center of the insurance company, in which sending of important information on engine rpm and voltage to control module R is interrupted.
EFFECT: reduced probability of theft.
