Patent attributes
In a vehicle condition in which an engine rotation speed is likely to exceed a maximum rotation speed, since supercharging by a supercharger is curbed, it is possible to curb an increase in an engine torque. Even when the engine rotation speed exceeds the maximum rotation speed, the engine rotation speed is made less likely to increase by control of decreasing the engine torque. In a vehicle condition in which the engine rotation speed is less likely to exceed the maximum rotation speed, since a supercharging pressure becomes relatively high, it becomes easier to secure power performance. Accordingly, it is possible to curb a decrease in power performance due to curbing of supercharging and to prevent an engine from falling into a high-rotation state in which the engine rotation speed exceeds the maximum rotation speed.
