Control unit and data transmitting method
View Patent ↗A control unit receives a data request signal transmitted from a data recording apparatus, and then transmits a control parameter, which corresponds to the data request signal, out of control parameters used to execute control of a vehicle to the data recording apparatus. In this case, a transmission state of a transmitting section at a time of shutdown is stored as a communication history. Therefore, when the communication history is stored in a storing section, the transmission state at the time of shutdown is restored in a starting process executed after a power supply is turned ON, based on the read communication history.
1. A control unit capable of transmitting/receiving information to/from a data recording apparatus to execute control of a vehicle, comprising:
a receiving section that receives a data request signal transmitted from the data recording apparatus;
a transmitting section that transmits a control parameter, which corresponds to the data request signal, out of control parameters used to execute the control of the vehicle, to the data recording apparatus; and
a storing section that stores an operating history including an operating state of the data recording apparatus at a time of shutdown, the operating state comprising acquired contents including types of control parameters to be recorded in the data recording apparatus and at least one of acquiring conditions including a sampling rate, trigger conditions, and a recording time,
wherein, when the operating history is stored in the storing section, the transmitting section reads the operating history from the storing section in a starting process executed after a power supply is turned ON, and
wherein the transmitting section restores the operating state at the time of shutdown based on the read operating history.
2. The control unit according to claim 1 , wherein, when the receiving section receives a signal to continue the operating state from the data recording apparatus, the transmitting section restores the operating state.
3. The control unit of claim 1 , wherein operating state comprises an identification of a method of transmitting said control data to said data recording apparatus.
4. A controller that communicates control data to a data recorder in a vehicle, comprising:
a receiver that receives a data request signal from the data recorder;
a transmitter that transmits control data to the data recorder; and
a storage that stores an operating history including an operating state of the data recorder at a shutdown, the operating state comprising acquired contents including types of control parameters to be recorded in the data recorder and at least one of acquiring conditions including a sampling rate, trigger conditions, and a recording time.
5. The controller of claim 4 , wherein the transmitter reads the operating history from the storage in a starting process.
6. The controller of claim 5 , wherein the transmitter reads the operating history from the storage in a starting process in response to power being supplied to the controller.
7. The controller of claim 4 , wherein the transmitter restores the operating state based upon the operating history.
8. The controller of claim 4 , wherein the operating state comprises an identification of a method of transmitting said control data to said data recorder.
9. The controller of claim 4 , wherein the transmitter transmits control data to the data recorder in response to the receiver receiving the data request signal.
10. A controller that communicates control data to a data recorder in a vehicle, comprising:
means for receiving a data request signal from the data recorder;
means for transmitting control data to the data recorder; and
means for storing an operating history including an operating state of the data recorder at a shutdown, the operating state comprising acquired contents including types of control parameters to be recorded in the data recorder and at least one of acquiring conditions including a sampling rate, trigger conditions, and a recording time.
11. The controller of claim 10 , wherein the operating state comprises an identification of a method of transmitting said control data to said data recorder.
12. The controller of claim 10 , wherein said means for transmitting reads the operating history from the storage in a starting process.
13. The controller of claim 12 , wherein the means for transmitting reads the operating history from the storage in a starting process in response to power being supplied to the controller.
14. The controller of claim 10 , wherein the means for transmitting restores the operating state based upon the communication history.
15. The controller of claim 10 , wherein the means for transmitting transmits control data to the data recorder in response to the means for receiving the data request signal.
