摘要：A vehicle-mounted device communication controller includes a vehicle-mountedunit for communicating with ID-registered portable units, a switch-detection mechanism

for detecting pressing of an operation knob, a switch-operation restriction mechanism forrestricting the rotation of the knob, and a door-opening/closure detection mechanismfor detecting opening and closure of a door. Signals are exchanged between the vehicle-mounted unit and each portable unit, and a portable unit having succeeded in exchangingthe signals is authenticated and released from the restriction. The vehicle-mounted unitincludes a sending/receiving part, a controller, an authentication part, and an ID-storagepart. When the door-opening/closure detection mechanism detects opening and thenclosure of the door, the controller performs the search by an all search method, andonly when the latest authenticated ID is stored in the ID-storage part, performs thesearch by an urgent search method using a simple response signal which does not includean ID.
