| 20100312460 | ECO-RUN CONTROL DEVICE AND ECO-RUN CONTROL METHOD - An eco-run control unit performs an eco-run control of stopping an engine mounted on a vehicle automatically on the basis of stop conditions and of restarting the engine automatically on the basis of restart conditions while the engine is stopped automatically by the eco-run control. An acquiring unit acquires information for identifying a vehicle type of the vehicle on which the eco-run control device is mounted. A determining unit determines whether the identified vehicle type is coincident with any of vehicle types stored in a storage unit. A setting unit sets the eco-run control to a specific control depending on one of the vehicle types when the determining unit determines that the identified vehicle type is coincident with the one of the stored vehicle types. The setting unit sets the eco-run control to a default control corresponding to a default vehicle type and permit the eco-run control unit to stop the engine automatically until a determination of the determination unit is completed. The setting unit prohibits the eco-run control unit from stopping the engine automatically when the determining unit determines that the identified vehicle type is different from any of the stored vehicle types. | 12-09-2010 |

A prohibiting unit is configured to prohibit the control unit from performing the eco-run control when the test unit determines that the starter driving unit is out of order. The prohibiting unit prohibits the control unit from performing the eco-run control in a case where the nullifying unit nullifies the failure test by the test unit during a test period in which the test unit performs the failure test. | 01-06-2011 |
| 20110098904 | DATA WRITE DEVICE AND DATA WRITE METHOD - A data write device receives power supply from a first system guided from a power source and writes data in a nonvolatile first storage unit. A request generation unit generates a write request to write data in the first storage unit under a predetermined condition. A receiving unit receives the write request from a user. A second storage unit receives power supply from a second system guided from the power source and is able to store data. A first write unit writes target data to be written, which is stored in the second storage unit, in the first storage unit in response to the write request. A second write unit writes the target data which is stored in the second storage unit, in the first storage unit if the power supply from the first system is stopped and then restarted at the time of writing by the first write unit. A display control unit causes a display device which carries out predetermined initial display when the power supply from the first system is stopped and then restarted, to display a write result of the target data in the first storage unit. The second write unit is activated when the request generation unit generates the write request and is not activated when receiving the write request from the user. | 04-28-2011 |
