Abstract
A deceleration control apparatus for a hybrid electric vehicle in which an electric motor conducts regenerative braking when the vehicle is to be decelerated comprises a braking unit for applying a braking force on a drive member transmitting drive power converted by a parallel axes-type automatic transmission to wheels, and a control unit for controlling the braking unit to apply a braking force on the drive member while a downshift is being conducted in the automatic transmission in the process of deceleration of the vehicle.
Claims4
A deceleration control apparatus for a hybrid electric vehicle having an engine;
- an electric motor acting as a motor by being supplied with electric power from a battery;
- and a parallel axes-type automatic transmission for transmitting drive power from the engine and/or the electric motor, converted by using a set of gear wheels corresponding to a selected gear, to drive wheels via a drive member, the electric motor being capable of acting as a generator to conduct regenerative braking and store generated electric power in the battery when the vehicle is to be decelerated,
- the deceleration control apparatus comprising:
- a braking unit for applying a braking force on the drive member;
- and
- a control unit for controlling the braking unit to apply a braking force on the drive member while a downshift is being conducted in the automatic transmission in the process of deceleration of the vehicle.
