Abstract
A receiving unit receives a signal in a frequency band used in vehicle-to-vehicle communications or shared by vehicle-to-vehicle communications and road-to-vehicle communications. A demodulation unit demodulates the signal received with the receiving unit. A received signal strength detection unit detects a received signal strength of the signal received with the receiving unit. A demodulation state determination unit determines whether the signal, which is received with the receiving unit, is demodulated successfully. A notification processing unit notifies a driver of a possibility of existence of another vehicle in a condition where the demodulation state determination unit determines that the signal is not demodulated successfully and where the received signal strength is greater than or equal to a predetermined strength threshold, which is for determining whether signals sent from multiple other vehicles collide against each other.
