HYBRID VEHICLE RAPID DECELERATION CONTROL DEVICE

摘要

Provided is a hybrid vehicle in which a motor/generator 5 is positioned between an engine 1 and an automatic transmission 3, the engine 1 and the motor/generator 5 are connected through a first clutch 6 and a second clutch 7 is provided between the motor/generator 5 and a drive road wheel 2. In an HEV mode in which the first clutch 6 is engaged, when deceleration of a vehicle is determined to be rapid deceleration of a threshold value or greater, the first clutch 6 is released and at the same time fuel supply to the engine 1 is stopped through an engine controller 21. Even when, due to rapid decelerating, the engine speed Ne drops to an idling speed or lower due to delay in the release of the first clutch 6, there is no combustion or explosion and thus floor vibration does not occur.
