Abstract
A hybrid electric vehicle is arranged such that a driving force of an engine and a driving force of an electric motor can be transmitted to driving wheels through a transmission and that the engine and the transmission can be mechanically connected and disconnected by means of a clutch. When an upper limit decelerating torque generable by the electric motor is equal to or greater than a requested decelerating torque, a vehicle ECU disengages the clutch and controls the electric motor to generate the requested decelerating torque. Meanwhile, when the upper limit decelerating torque is smaller than the requested decelerating torque, the vehicle ECU engages the clutch and controls the engine and the electric motor so that the sum of a decelerating torque generated by the engine and a decelerating torque generated by the electric motor is equal to the requested decelerating torque.
