VEHICLE-MOUNTED DEVICE CONTROL SYSTEM

WIPO Patent Application WO/2010/084760

A1

A vehicle-mounted device control system, wherein the collation of a portable machine (200) is carried out by performing intercommunication in which the portable machine (200) returns a response signal in response to the request signal transmitted by a vehicle-side unit (100) mounted in a vehicle, and vehicle-mounted devices are controlled according to the result of the collation. If the collation is not established, communication frequencies are so switched as to perform the intercommunication, and the collation is carried out again. When a door lock sensor (140) is operated by a user, the vehicle-side unit (100) firstly performs the vehicle exterior collation, and if the collation is established, the vehicle-side unit (100) stores a communication frequency at the time when the collation was established in a memory (112) (S10 to S13), and sets the communication frequency stored in the memory (112) as a communication frequency to be designated for the portable machine (200) at the next time when the vehicle-side unit (100) performs the vehicle interior collation (S16).
