Abstract
Official abstract text for this publication.
In a case of engagement when a clutch K 0 disposed between an engine 12 and a motor generator MG is engaged during EV running while a release instruction for the clutch K 0 is output, drive of the engine 12 is changed such that a rotation speed N E of the engine 12 approaches a rotation speed N MG of the motor generator MG and, therefore, a drag torque of the engine 12 can be suppressed regardless of an engagement state of the clutch K 0 , and generation of longitudinal acceleration can be suppressed by reducing a slip time of the clutch K 0 . Therefore, a control device of a hybrid vehicle 10 can be provided that reduces a driver's uncomfortable feeling in a simplified manner in a case of wrong engagement of the clutch K 0.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control device of a hybrid vehicle having a clutch in a power transmission path between an engine and a motor generator, the clutch controlling power transmission through the power transmission path depending on an engagement state, the control device interrupting the power transmission through the power transmission path by releasing the clutch during motor running, only the motor generator being used as a drive source for running in the motor runnin…
