Abstract
A vehicle includes an internal combustion engine that is variably connected, for example, via a mechanical clutch, to a drive train including a transmission. The vehicle also has a functional device operated by a torque generated by the internal combustion engine. A load applied by the functional device on the internal combustion engine when the drive train and the engine are engaged during deceleration of the vehicle and a speed of the internal combustion engine is lower than a predetermined value is controlled such that the load is reduced to a first value lower than a second value of the load applied to the engine when the speed of the internal combustion engine is equal to or higher than the predetermined value.
