  • Patent number: 10476962
    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.

  • Patent number: 9596656
    Abstract: A vehicular wireless transmission apparatus includes a memory that stores (i) a default adjustment value relative to a default vehicle model, (ii) a default vehicle model data indicating the default vehicle model, and (iii) a correction value table for correcting the default adjustment value to be compliant with each of different vehicle models different from the default vehicle model. When a host vehicle model data read from a different ECU does not match with the default vehicle model data stored in the memory, it is determined that the vehicular wireless transmission apparatus is presently mounted in a host vehicle model indicated by the host vehicle model data read from the different ECU. The default adjustment value is then corrected by retrieving a correction value corresponding to the host vehicle model data from the correction value table.

  • Patent number: 9549369
    Abstract: A communication device has an information transmission setting process that obtains state information indicative of a self-vehicle state, and determines whether the state information satisfies a transmission stop condition for stopping a transmission of position information. Further, based on the obtained state information, the process determines whether the self-vehicle is in an abnormal state indicative of an abnormality of the self-vehicle. Then, if the preset transmission stop condition is satisfied and the abnormal state is not detected, the process stops the transmission of the position information. If the preset transmission stop condition is satisfied and the abnormal state is already detected, the process allows a periodic transmission of the position information.
