HIGH-JACKED CARS RADIO SEARCH METHOD Russian patent published in 2008 - IPC B60R25/10 G08B25/08 

FIELD: transport engineering.

SUBSTANCE: invention relates to radio search technologies used in finding of high-jacked vehicles and designed for operative searching of cars. Car is furnished with mobile cellular communication network terminal containing SIM card. In case of high-jacking, message is sent from mobile telephone of car User of from tracking center.

Said bearings are used for locating high jacked vehicle. Design peculiarities of method come to recording and storing of message stating fact of high jacking sent from mobile telephone of car User or from tracking center in mobile cellular communication network. Car module is kept n duty with supply disconnected. O-duty mode is switched on in preset moments of time required for setting two-side communication with base stations. Message stating fact of high jacking kept in memory of mobile cellular communication network is sent, said message is received by terminal after which car module change-over to on-duty mode is prohibited. Operator of dispatcher center, car user or tracking center operator receiver message stating fact of car high jacking.
