  • Patent number: 9376970
    Abstract: In a vehicle control device for performing control to stop and start an engine according to a traveling state of a vehicle regardless of an operation of stopping and starting the engine by a driver, the stopping of the engine is limited based on a starting endurance ability of the engine. Thus, an endurance number of years of a starter can be ensured. If a contribution degree in improving a fuel economy by the stopping of the engine at the time of parking is high, the effect of improving the fuel economy can be suppressed from reducing by prohibiting the automatic stopping of the engine 4 during traveling. The effect of improving the fuel economy by stopping the engine can be enhanced by ensuring the endurance number of years of the starter.

  • Publication number: 20130244834
    Abstract: In a vehicle brake system, which starts an engine-for recovering a brake negative pressure of a servo unit connected to an intake pathway of the engine, a valve opening of a throttle valve of the engine is controlled in an opening direction when the engine is started for recovering the brake negative pressure during running. It is desired that recovery control of the brake negative pressure by valve opening control of the throttle valve is performed during brake pressing operation by a driver.

  • Patent number: 8521394
    Abstract: A main ECU (71) for generating an actual acceleration/deceleration running pattern based on a current running situation of a vehicle, generating a corrected acceleration/deceleration running pattern obtained by elongating an actual acceleration/deceleration period of the actual acceleration/deceleration running pattern when an actual acceleration/deceleration period (T1) in the actual acceleration/deceleration running pattern is shorter than a reference acceleration/deceleration period (T0) set in advance, and setting the actual acceleration/deceleration running pattern as a best acceleration/deceleration running pattern when the corrected acceleration/deceleration running pattern is not generated and setting the corrected acceleration/deceleration running pattern as the best acceleration/deceleration running pattern when the corrected acceleration/deceleration running pattern is generated, is provided.
