Abstract
A vehicle information processing apparatus provided in a vehicle is provided with a TPMS valve that includes an air pressure sensor which obtains a tire air pressure as wheel information and a wheel-side communication device that transmits the wheel information and an ID unique to that wheel-side communication device at regular intervals; an ECU which receives the wheel information from the wheel-side communication device in each TPMS valve via a vehicle body-side communication device and processes that wheel information; and an onboard battery which supplies power to the ECU. Upon receiving a command to shift into a verification mode while power is being supplied from the onboard battery, the ECU performs a predetermined verification based on a signal transmitted at regular intervals from each wheel-side communication device. After receiving the command to shift into the verification mode, the ECU remains in the verification mode until a preset condition is satisfied.
