On-vehicle radar device and on-vehicle radar device control system

摘要

An on-vehicle radar device comprises a transceiver (101) which transmits/receives a monitoring signal at a specified frequency band and transmits a priority order signal at a frequency within the above-mentioned frequency band, and a controller (10) which switches the signals transmitted by the transceiver (101). The transceiver (101) receives a priority order signal of another radar device, and when interference with the signal of the other radar device is detected, the controller (10), based on the priority order of that other device and on the priority order of the device itself, shifts, by a specified frequency, the frequency band of the monitoring signal transmitted by the transceiver (101).
