摘要： A road surface slope estimating device includes a forward/backward sensor that outputs a detected forward/backward of a vehicle, a forward/backward estimator that calculates an estimated forward/backward of the vehicle, and a road surface slope estimating device that calculates an estimated road surface slope value using the detected forward/backward and the estimated forward/backward. The road surface slope estimating device implements a momentarily rough terrain determination step to determine whether the vehicle is traveling on momentarily rough terrain or continuously rough terrain. When it is determined that the vehicle is traveling on momentarily rough terrain, the road surface slope estimating device fixes the estimated road surface slope value to an estimated road surface slope value obtained immediately before the determination is made.

摘要： In an internal combustion engine, fuel injection is stopped to automatically stop the engine when automatic stop conditions are met. The engine is started in response to a request to restart the engine while an engine speed is decreasing due to an automatic stoppage by resuming fuel injection if the engine speed is equal to or greater than a combustion recoverable rotational speed threshold, and by using an electric motor if the engine speed is less than the combustion recoverable rotational speed threshold. When the engine speed of the internal combustion engine falls below the combustion recoverable rotational speed threshold while the engine speed is decreasing due to an automatic stoppage, an amount of air entering cylinders is reduced to be less than before the engine speed fell below the combustion recoverable rotational speed threshold.

摘要： In an internal combustion engine, fuel injection is stopped to automatically stop the engine when automatic stop conditions are met. When there is a request to restart the engine while an engine speed is decreasing due to automatic stoppage, the engine is started by resuming fuel injection if the engine speed is equal to or greater than a combustion recoverable rotational speed threshold, at which restarting is possible only by fuel injection. When there is a request to restart the engine while an engine speed is decreasing due to automatic stoppage, the engine is started using a starter motor if the engine speed is less than the combustion recoverable rotational speed threshold. When there is a request to restart the engine in a brake ON state, the engine is not started by resuming fuel injection, but rotated and started using the starter motor.

摘要： If an internal combustion engine that has been automatically stopped is to be restarted under a decreased engine speed, a control unit of the internal combustion engine starts cranking when a crank angle of a cylinder in compression stroke of the internal combustion engine is closer to bottom dead center than a threshold value set in advance. More specifically, if an engine speed of the internal combustion engine is in forward rotation, the cranking is begun when the crank angle of the cylinder in compression stroke is closer to the bottom dead center than a threshold value set in advance. If the engine speed of the internal combustion engine is in backward rotation, the cranking is begun when the crank angle of the cylinder in compression stroke is closer to the bottom dead center than another threshold value set in advance.
