Vehicle speed regulating method, involves accelerating vehicle again in optimized consumption over upper threshold value for speed in roll-out phase, when vehicle attains lower threshold value

摘要

The method involves accelerating a vehicle for an upper threshold value higher than nominal speed, in an acceleration phase. The vehicle is again accelerated in optimized consumption over the upper threshold value for speed, in a roll-out phase when the vehicle attains a lower threshold value. An internal combustion engine is deactivated if the vehicle has an electric motor, in the roll-out phase.
