Abstract:
1. An automatic locking system for vehicles that communicates with an electronic key in a predetermined range outside a vehicle cabin as a communication area and comprises an outside-cabin comparing unit for comparing an ID code included in a signal transmitted from the electronic key with an ID code registered in advance, the automatic locking system locking all entry-and-exit doors of a vehicle when a comparison result of the outside-cabin comparing unit has changed from OK to NG in a case where all of the entry-and-exit doors are closed; wherein the outside-cabin comparing unit communicates with the electronic key when a right-side entry-and-exit door is opened/closed to compare the ID code included in the signal transmitted from the electronic key with the ID code registered in advance, and communicates with the electronic key when a left-side entry-and-exit door is opened/closed to compare the ID code included in the signal transmitted from the electronic key with the ID code registered in advance; the automatic locking system further comprises a comparison history storing unit that, when either one of the right-side entry-and-exit door and the left-side entry-and-exit door is opened/closed, stores comparison history in a memory when the comparison result of the outside-cabin comparing unit has changed from OK to NG in a case where not all of the entry-and-exit doors are closed; and all of the entry-and-exit doors are locked in a case where the comparison history has been stored in the memory when all of the entry-and-exit doors are closed.
