Method for changing from a coasting or free-rolling mode of a motor vehicle to a fuel cut-off mode


The invention relates to a method and device for changing from a coasting or free-rolling mode of a motor vehicle with an internal combustion engine and an automatic clutch, which is disengaged during the coasting or free-rolling mode, to a fuel cut-off mode, in which the clutch is engaged, wherein before engagement of the clutch the internal combustion engine is brought to a revolution rate at which the engagement of the clutch induces no or only small changes in revolution rate in the drive train, and whereby the fuel supply to the internal combustion engine is reduced following engagement of the clutch. Under one or more predetermined conditions the increase of the drag torque of the internal combustion engine acting on the motor vehicle during the changeover from coasting or free-rolling mode to fuel cut-off mode takes place so slowly that the change is not usually noticed by the driver..
