IPC: F16D48/02
Filed: 2019-03-11
Abstract: To resolve the problem in which: when the centroid of an engine side revolving body and the centroid of a motor side revolving body are near in the circumferential direction when viewed from the direction of a rotation center axis, the centroid of a drive shaft that consists of the engine side revolving body and the motor side revolving body deviates greatly from the rotation center axis; and when the centroid of the whole drive shaft deviates, vibration or noises are more likely to occur when components of the drive shaft rotate.SOLUTION: When an internal combustion engine and a motor generator are both stopped, a clutch is in an open state. In this state, an engine side revolving body is stopped so that the centroid is in a lower section of a vehicle. During balance control, the clutch is first brought into a slip state and the engine side revolving body and a motor side revolving body are relatively rotated. Next, the clutch is switched to a direct-coupled state when the centroid position of the engine side revolving body and the centroid position of the motor side revolving body are separated circumferentially by 180 degrees from when the clutch is brought into the slip state.SELECTED DRAWING: Figure 3
