Abstract: A hybrid electric vehicle includes an engine, a motor, a battery, a coupling mechanism, an electric power generating mechanism, and a vehicle controller. The engine and motor drive driving wheels. The battery supplies electric power for running to the motor. The coupling mechanism switches coupling of the engine and the driving wheels between direct coupling and buffering coupling. The electric power generating mechanism generates electric power. The vehicle controller switches a running mode of the hybrid electric vehicle between a first running mode and a second running mode with higher running performance. The vehicle controller limits the electric power generation under a first condition when the buffering coupling is applied during the first running mode and limits the electric power generation under a second condition less limited than the first condition when the buffering coupling is applied during the second running mode.

Abstract: A vehicle control device configured to be capable of executing idle stop control to automatically stop an engine when a predetermined automatic stop condition is satisfied and restart the engine when a predetermined restart condition is satisfied during the automatic stop of the engine, the vehicle control device includes: a start request detector, a shift position detector, and a delay time setting module. A start request detector detects a driver operation indicating a request for starting the engine by a driver. A shift position detector detects a shift position of a shift changer. A delay time setting module sets, on a basis of presence or absence of the driver operation and the shift position, a delay time from when the engine is restarted until when an automatic stop of the engine is permitted.

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.
