Document Type and Number:
Japanese Patent JP7183924
Kind Code:
B2
Abstract:
When a learning condition is satisfied, an ECU starts learning processing and controls opening of a throttle valve in accordance with a first map. The ECU calculates a difference between an actual rotation speed and a target rotation speed of the engine at the current time. When magnitude of the difference is equal to or larger than a prescribed value, the ECU performs second learning processing. In second learning processing, the ECU controls a first MG to set a rotation speed of the engine to an idle rotation speed by using output torque from the first MG. How much the throttle valve's opening is corrected is calculated based on torque of the first MG required for setting the rotation speed of the engine to the idle rotation speed, and opening of the throttle valve is updated. The first map is updated based on updated opening of the throttle valve.
