Abstract

A vehicle-mounted malfunction notification apparatus having a communication malfunction notification unit that notifies a vehicle operator of a communications malfunction when a malfunction occurring in a communications device persists for a specified period of time, includes a maintenance operation checking unit and a maintenance operation processing unit. The maintenance operation checking unit determines whether a maintenance operation for the communications device is being performed. The maintenance operation processing unit notifies the vehicle operator that the maintenance operation is being performed when the maintenance operation checking unit determines that the maintenance operation is being performed.

Claims

1. A vehicle-mounted malfunction notification apparatus that includes a communication malfunction notification unit to inform a vehicle operator of a communications malfunction when the communications malfunction is detected to persist for a specified period of time, the apparatus comprising:

a maintenance operation checking unit that determines whether a maintenance operation for the communications device or related parts of the communications device is being performed; and

a maintenance operation processing unit that performs a process for informing the vehicle operator that the maintenance operation is being performed when the maintenance operation checking unit determines that the maintenance operation is being performed.

2. The vehicle-mounted malfunction notification apparatus according to claim 1, wherein the maintenance operation processing unit includes a maintenance operation notification unit that notifies the vehicle operator that the maintenance operation is being performed when the maintenance operation checking unit determines that the maintenance operation is being performed.

3. The vehicle-mounted malfunction notification apparatus according to claim 2, wherein when the communications device is detected to be operating normally after starting the notification that the maintenance operation is being performed, the maintenance operation notification unit discontinues notifying the vehicle operator that the maintenance operation is being performed.

4. The vehicle-mounted malfunction notification apparatus according to claim 1, wherein the maintenance operation processing unit includes a communication malfunction persistence-period reducing unit that shortens the specified period of time comparatively when the maintenance operation checking unit determines that the maintenance operation is

5. The vehicle-mounted malfunction notification apparatus according to any one of claims 1 to 4, wherein when a communications malfunction occurs between transmitters and a receiver of a system that detects tire air pressures of the vehicle persists for the specified period of time, the communication malfunction notification unit turns on or blinks an indicator lamp installed in an instrument cluster to notify the vehicle operator of the communications malfunction.

6. The vehicle-mounted malfunction notification apparatus according to claim 5, wherein, the maintenance operation notification unit turns on or blinks the indicator lamp to inform the vehicle operator that the maintenance operation is being performed.

7. A vehicle-mounted malfunction notification method that informs a vehicle operator of a communications malfunction when the communications malfunction of a communications device persists for a specified period of time, the method comprising:

determining whether a maintenance operation for the communications device, or related parts of the communications device, is being performed; and

performing a process, when it is determined that the maintenance operation is being performed, to notify the vehicle operator that the maintenance operation is being performed.

8. The vehicle-mounted malfunction notification method according to claim 7, wherein the process for notifying the vehicle operator that the maintenance operation is being performed includes giving an indication to the vehicle operator to notify that the maintenance operation is being performed.

9. The vehicle-mounted malfunction notification method according to claim 8, wherein when the communications device is detected to be operating normally after starting the notification that the maintenance operation is being performed, the notification to the vehicle operator that the maintenance operation is being performed is discontinued.

10. The vehicle-mounted malfunction notification according to any one of claims 7 to 9, wherein the specified period of time is set to a shorter period of time when process for notifying the vehicle operator that the maintenance operation is being performed.

11. The vehicle-mounted malfunction notification method according to any one of claims 7 to 10, wherein when the communications malfunction between transmitters and a receiver of a system that detects tire air pressures of the vehicle persists for the specified period of time, an indicator lamp installed in an instrument cluster is turned on or blinked to inform the vehicle operator of the communications malfunction.

12. The vehicle-mounted malfunction notification method according to claim 11, wherein the indicator lamp is turned on or blinked to notify the vehicle operator that the maintenance operation is being performed.
