Abstract
An MG1 torque at a time of decreasing an engine speed of an engine is made larger when a turbocharging pressure by a turbocharger is higher than when the turbocharging pressure is lower. In this way, even if the losses of pumps of the engine differ due to the remaining turbocharging pressure during a transition of stopping the engine in turbocharging, it is possible to appropriately reduce the engine speed. Therefore, when the engine is being brought to a stop, it is possible to appropriately suppress vibration generated in the vehicle.
Claims7
A control device for a hybrid vehicle including an engine with a turbocharger and a rotating machine that is able to adjust an engine speed of the engine, the control device comprising an engine stop controller configured to stop fuel supply to the engine and control an output torque of the rotating machine to apply a torque for reducing the engine speed of the engine to the engine, when the engine is being brought to a stop,
- wherein the engine stop controller is configured to make the output torque of the rotating machine at a time of decreasing the engine speed of the engine larger when a turbocharging pressure by the turbocharger is higher than when the turbocharging pressure is lower.
