Abstract

A state judgment unit (21) of an on-vehicle terminal (20) judges whether the vehicle is in operation by using outputs of the operation state of a mobile terminal (10), a key insert switch (32), an ignition switch (33), and a courtesy switch (34). A theft detection unit (22) includes a diagnosis processing unit (22a) and a monitoring processing unit (22b). When the vehicle is in operation, the diagnosis processing unit (22a) executes diagnosis of a human body sensor (41), a vibration sensor (42), and a microphone (43). When the vehicle is not in operation state, the monitoring processing unit (22b) monitors presence/absence of theft action by using the outputs of the human body sensor (41), the vibration sensor (42), and the microphone (43).

Claims

1-15. -15. (canceled)

16. A vehicle control apparatus that performs a monitoring control of a vehicle in a non-driving state based on a sensor that collects information for the monitoring control, the vehicle control apparatus comprising:

a driving-state determining unit that determines a driving state of the vehicle; and

a fault diagnosis unit that performs a fault diagnosis of the sensor upon the driving-state determining unit determining that the vehicle is in a driving state.

17. The vehicle control apparatus according to claim 16, wherein if the sensor is normal, an output from the sensor is changed while the vehicle is in the driving state.

18. The vehicle control apparatus according to claim 16, wherein

the sensor is a human detecting sensor that detects a human body with at least one of ultrasonic wave and radio wave, and

the monitoring control is to monitor an intrusion of a person into the vehicle based on an output from the human detecting sensor.

19. The vehicle control apparatus according to claim 16, wherein

the sensor is a vibration detecting sensor that detects a vibration of the vehicle, and

the monitoring control is to monitor a vehicle theft based on an output from the vibration detecting sensor.

20. The vehicle control apparatus according to claim 16, wherein

the sensor is an impact-sound sensor that detects an impact sound, and

the monitoring control is to monitor an occurrence of an impact on at least one of a body and a glass of the vehicle.

21. the vehicle control apparatus according to claim 16, wherein when the vehicle is in the driving state, and when the sensor outputs what is supposed to be output along with a driving operation, the fault diagnosis unit diagnoses that the sensor is normal.

22. The vehicle control apparatus according to claim 16, wherein when the vehicle is in the driving state, and when the sensor dose not output what is supposed to be output along with a driving operation, the fault diagnosis unit diagnoses that the sensor has a fault.

23. The vehicle control apparatus according to claim 22, wherein when the vehicle is in the driving state, and if the sensor dose not output what is supposed to be output along with the driving operation for a predetermined time, the fault diagnosis unit diagnoses that the sensor has a fault.

24. The vehicle control apparatus according to claim 22, wherein the fault diagnosis unit performs the fault diagnosis during one trip from a beginning of driving to an end of driving, and if the fault diagnosis unit diagnoses that the sensor is faulty across a plurality of trips, the fault diagnosis unit diagnoses that the sensor has a fault.

25. The vehicle control apparatus according to claim 16, wherein the fault diagnosis unit makes a notification of a result of the fault diagnosis after a vehicle driving is ended.

26. The vehicle control apparatus according to claim 16, wherein when an ignition switch is turned ON, the driving-state determining unit determines that the vehicle is in the driving state.

27. The vehicle control apparatus according to claim 16, wherein when an engine is in operation, the driving-state determining unit determines that the vehicle is in the driving state.

28. The vehicle control apparatus according to claim 16, wherein when the vehicle is running at a predetermined speed or faster, the driving-state determining unit determines that the vehicle is in the driving state.

29. The vehicle control apparatus according to claim 16, further comprising a power managing unit that manages a power supply to the sensor, wherein

the power managing unit selectively performs the power supply to the sensor when the monitoring control is performed using the sensor and when the fault diagnosis of the sensor is performed.

30. A vehicle control method of performing a monitoring control of a vehicle in a non-driving state based on a sensor that collects information for the monitoring control, the vehicle control method comprising:

determining a driving state of the vehicle; and

performing a fault diagnosis of the sensor when it is determined that the vehicle is in a driving state.
