Abstract

A TCU is provided to resolve an abnormal state while minimizing loss of convenience for a user. The TCU which communicates with a server terminal providing service for a vehicle via a mobile telephone network for receiving provision of the service, includes a main control unit, and a communication module for communicating with the mobile telephone network. The main control unit resets an operation state of the communication module when communication for receiving the service is not available.

Claims

1. A vehicle mounted communication unit which communicates with a server terminal providing service for a vehicle via a mobile communication network for receiving provision of the service, the vehicle mounted communication unit comprising:

a main control unit configured to control the vehicle mounted communication unit and including a CPU, a ROM, and a RAM; and

a communication module including a communication control unit, which includes a CPU, a ROM, and a RAM, and a communication unit performing communication through the mobile communication network under control of the communication control unit,

wherein the main control unit includes

a communication abnormality detecting unit detecting a communication abnormality of the communication via the communication module when communication connection cannot be performed at any of plural elements including the server terminal, the mobile communication network, and the communication module, and

a restoration execution unit executing restoration operation performed by resetting an operation state of the communication module at a timing when the communication abnormality is detected by the communication abnormality detecting unit, and the restoration execution unit starting the restoration operation at a different timing depending on at which element communication connection cannot be performed.

2. The vehicle mounted communication unit according to claim 1,

wherein the restoration execution unit executes the restoration operation at the timing when connection to the mobile communication network cannot be performed over a predetermined period, when communication with the server terminal is failed over a predetermined number of times, or promptly when the communication module does not respond.

3. The vehicle mounted communication unit according to claim 1,

wherein a power saving mode in which power consumption is suppressed is provided as an operation mode, and

the restoration execution unit resets the operation state of the communication module every time the operation mode is returned from the power saving mode.

4. The vehicle mounted communication unit according to claim 3,

wherein the main control unit returns the operation mode from the power saving mode when communication transmitted from the server terminal is received or when predetermined conditions in which it is determined that data is transmitted to the server terminal are satisfied.

5. The vehicle mounted communication unit according to claim 3,

wherein the main control unit makes the operation mode shift to the power saving mode when a power source of the vehicle is stopped, and

the main control unit returns the operation mode from the power saving mode and resets the operation state of the communication module when the power source is started.

6. The vehicle mounted communication unit according to claim 1, further comprising:

an interface unit connected to a vehicle mounted network provided at the vehicle,

wherein a signal is transmitted/received to/from an electric component or vehicle mounted equipment connected to the vehicle mounted network through the interface unit.

7. A service provision system comprising:

a server terminal providing service for a vehicle; and

a vehicle mounted communication unit communicating with the server terminal via a mobile communication network for receiving provision of the service,

wherein the vehicle mounted communication unit includes

a main control unit configured to control the vehicle mounted communication unit and including a CPU, a ROM, and a RAM; and

a communication module including a communication control unit, which includes a CPU, a ROM, and a RAM, and a communication unit performing communication through the mobile communication network under control of the communication control unit,

wherein the main control unit includes

a communication abnormality detecting unit detecting a communication abnormality of the communication via the communication module when communication connection cannot be performed at any of plural elements including the server terminal, the mobile communication network, and the communication module, and

a restoration execution unit executing restoration operation performed by resetting an operation state of the communication module at a timing when the communication abnormality is detected by the communication abnormality detecting unit, and the restoration execution unit starting the restoration operation at a different timing depending on at which element communication connection cannot be performed.

8. The service provision system according to claim 7,

wherein

the main control unit has a power saving mode in which power consumption is suppressed as an operation mode, and

the restoration execution unit resets an operation state of the communication module every time the operation mode is returned from the power saving mode.
