PROBLEM TO BE SOLVED: To further improve fuel consumption by controlling consumption of a battery when connecting a clutch device to switch to the HEV travel in a hybrid vehicle which improves the fuel consumption by interrupting the clutch device at EV travel and separating a first motor generator.SOLUTION: While a clutch CL is connected without rotation synchronization control in high vehicle speed (V>Vs) in which consumption of a battery according to the rotation synchronization control of a first motor generator MG 1 is large, and is generous comparatively to the vibration and shock, the clutch CL is smoothly connected by doing the rotation synchronization control in low vehicle speed (V≤Vs) in which consumption of the battery according to the rotation synchronization control of a first motor generator MG 1 is small. As a result, the fuel consumption can be improved further by reducing the consumption of the battery while controlling a vibration and shock. |
