A second communication control part 14B controls the transmission part 20 so that, when the signal received by the first receiving part 16 is a measurement signal that is transmitted when an obstacle is detected, it stops transmission of the image data to the vehicle. A transmission control part of a vehicle controls the transmission part so as to transmit the vehicle discrimination signal, after an engine of the vehicle is started and before the vehicle starts traveling, and control the transmission part so as to transmit the measurement signal when the vehicle starts traveling.</p> |
