[Means for Solution] About each registered sensor ID, the unreceived malfunction judging portion 56 outputs a malfunction signal to the notification controller 53, when an unreceived period exceeds first setup time Tref1. The total unreceived period calculation portion 57 outputs a self-vehicle ID discrimination initiation instruction to ID discrimination/rewriting portion, when the sum total unreceived period Ttotal which is the sum total of the unreceived period of each registered sensor ID is calculated and the sum total unreceived period Ttotal exceeds second setup time Tref2. Before an unreceived period exceeds first setup time Tref1, registered sensor ID is rewritten and it can avoid reporting unreceived malfunction to a driver by this.
