Transmission control for a hybrid electric vehicle with regenerative braking
Abstract:
The present invention provide a hybrid vehicle comprising a first and a second transmission mechanisms, an electric motor connected to the first transmission mechanism, an internal combustion engine, a motor control unit and a transmission control unit. The transmission control unit changes, when the motor control unit executes a decelerating regeneration in response to a braking request of a driver, and when a braking request amount of the braking request is decreased by a predetermined amount while a predetermined shift range attained by the first transmission mechanism is selected, a shift range to a shift range on a lower-speed side than the predetermined shift range, which is attained by the first transmission mechanism, and to maintain the predetermined shift range when the braking request amount is not decreased.
