During the starting operation attendant with the starting device driving the vehicle this drive is also effected by energizing a clutch which connects the combustion engine via a transmission to the wheels L of the vehicle. By utilizing the starting device for the starting operation also for meanwhile driving the vehicle and/or accelerating same, a faster and/or more gradual drive/acceleration of the vehicle is realized. ## Claims ### Claim 1 A starting method for starting a combustion engine and/or driving wheels of a vehicle, the starting methods comprising the steps of: providing a starting device; connecting the combustion engine to an output shaft connected via a clutch to a transmission and/or wheels of the vehicle; connecting the starting device to the output shaft of the combustion engine between the combustion engine and the clutch; accelerating the output shaft by the starting device with the clutch open; closing the clutch before starting the engine, such that the wheels are driven by the starting device prior to the engine starting; and starting the engine so that the engine drives the wheels. ### Claim 2 (depends on 1) The starting method as claimed in claim 1, wherein the clutch is energized for driving or accelerating the vehicle prior to fuel being injected into the combustion engine. ### Claim 3 (depends on 1) The starting method as claimed in claim 1, wherein the clutch is energized for driving or accelerating the vehicle prior to the first combustion stage in the combustion engine being initiated. ### Claim 4 (depends on 1) The starting method as claimed in claim 1, wherein the starting device comprises a flywheel as well as a further clutch which is positioned between the flywheel and the output shaft of the combustion engine, wherein while the further clutch is being energized for starting the combustion engine by means of the flywheel, the clutch is also energized for driving or accelerating the vehicle. ### Claim 5 (depends on 4) The starting method as claimed in claim 4, wherein an auxiliary electromotor is connected to the flywheel, and wherein the auxiliary electromotor spins up the flywheel or maintains the flywheel at a correct number of revolutions before the further clutch is energized. ### Claim 6 (depends on 4) The starting method as claimed in claim 4, wherein the flywheel is spun up or maintained at a correct number of revolutions by energizing the further clutch while the combustion engine is running. ### Claim 7 (depends on 4) The starting method as claimed in claim 4, wherein there is a reduction gear present between the further clutch and the output shaft and an auxiliary clutch is present between the reduction gear and the output shaft, wherein during the revving up of the combustion engine the drive from the combustion engine to the reduction gear is interrupted by the auxiliary clutch.
