Vehicle anti-theft matching system

摘要

In a vehicle anti-theft matching system, password matching is effected only when a mismatch between a current vehicle position acquired from a car navigation system 1 and an authorized storage area registered in a position registration section 11 beforehand has existed for a period of time exceeding a given period. When the vehicle is returned to the authorized storage area within a given period of time, the vehicle is deemed to remain unstolen. Thus, password matching is not performed. Labor imposed on an authorized owner when his/her vehicle is driven in a normal state can be mitigated as compared with the case of a related-art system which always performs matching for identifying an authorized owner.
