Abstract: The present invention relates to a control device and a control method for an internal combustion engine including a fuel injection valve and an electric fuel pump. In stopping the internal combustion engine, the control device stops driving of the fuel pump and then fuel injection by the fuel injection valve, and increases the total amount of fuel injection by the fuel injection valve after stopping of driving of the fuel pump as the temperature of fuel in stopping the internal combustion engine decreases, thereby reducing a fuel pressure in a stop period. In this manner, fuel leakage from the fuel injection valve in the stop period can be reduced with a simple configuration.

Abstract: A vehicle control system is provided which is used in a vehicle equipped with an engine as a drive power source and works to establish engagement of a pinion of a starter motor with a ring gear mounted on a rotational axis of the engine and then actuate the starter motor to start the engine. The vehicle control system executes a preset mode to move the pinion to achieve the engagement with the ring gear when the rotation speed of the engine has dropped below a given threshold value. The threshold value is determined as a function of speed of the vehicle, thereby alleviating a driver's perception about unwanted mechanical noise arising from impact the pinion on the ring gear upon the engagement therebetween.
