deriving, as a function of the characteristic value, a travel speed at which the spoiler unit is to be moved between the first position and the second position; and transferring the spoiler unit between the first position and the second position at the derived travel speed. ### Claim 2 (depends on 1) The method of claim 1, wherein an increased positional difference results in an increased derived travel speed. ### Claim 3 (depends on 1) The method of claim 1, wherein the positional difference is determined from at least one travel distance between the first position and the second position and/or at least one travel angle between the first position and the second position. ### Claim 4 (depends on 1) The method of claim 1, wherein the transferring the spoiler unit between the first position and the second position at the derived travel speed includes: transferring, in an initial range between the first position and the second position, the spoiler unit one or more initial travel speeds, and transferring, in a central range between the first position and the second position, the spoiler unit at one or more central travels speeds, wherein the one or more initial travel speeds are lower than the one or more central travel speeds. ### Claim 5 (depends on 1) The method of claim 1, wherein the transferring the spoiler unit between the first position and the second position at the derived travel speed includes: transferring, in a central range between the first position and the second position, the spoiler unit at one or more central travels speeds, and transferring, in an end range between the first position and the second position, the spoiler unit at one or more end travel speeds, wherein the one or more end travel speeds are lower than the one or more central travel speeds. ### Claim 6 (depends on 1) The method of claim 1, wherein the transferring the spoiler unit between the first position and the second position at the derived travel speed includes transferring, in a central range between the first position and the second position, the spoiler unit at the derived travel speed. ### Claim 7 (depends on 1) The method of claim 1, wherein the transferring the spoiler unit between the first position and the second position at the derived travel speed includes: transferring, in an initial range between the first position and the second position, the spoiler unit one or more initial travel speeds, and transferring, in an end range between the first position and the second position, the spoiler unit at one or more end travel speeds, wherein the one or more initial travel speeds and the one or more end travel speeds are higher than a minimum speed. ### Claim 8 (depends on 1) The method of claim 1, wherein the transferring the spoiler unit between the first position and the second position at the derived travel speed includes setting a current travel speed by pulse width modulation. ### Claim 9 (depends on 1) The method of claim 1, wherein the transferring the spoiler unit between the first position and the second position at the derived travel speed includes: initially transferring the spoiler unit at a minimum speed, and continuously changing the travel speed from minimum speed to the derived travel speed. ### Claim 10 (depends on 1) The method of claim 1, further comprising periodically determining a current position of the spoiler unit. ### Claim 11 (depends on 1) The method of claim 1, wherein an end range between the first position and the second position includes a braking section. ### Claim 12 (depends on 11) The method of claim 11, wherein the braking section has a predefined positional difference. ### Claim 13 A spoiler device for a motor vehicle, comprising: at least one spoiler unit; at least one sensor device configured to measure a current position of the spoiler unit; an assigned control device configured to: actuate the drive device, determine a characteristic value for a positional difference between the current position of the spoiler unit and a second position, and derive, as a function of the characteristic value, a travel speed at which the spoiler unit is to be moved between the current position and the second position; and at least one drive device configured to transfer the spoiler unit between the current position and the second position at the derived travel speed. ### Claim 14 (depends on 7) The method according to claim 7, wherein the one or more initial travel speeds and the one or more end travel speeds are less than the derived travel speed. ### Claim 15 (depends on 1) The method according to claim 1, wherein the transferring the spoiler unit between the first position and the second position at the derived travel speed includes transferring the spoiler unit in an initial range between the first position and the second position at a time-varying initial travel speed, wherein the time-varying initial travel speed increases from zero to the derived travel speed. ### Claim 16 (depends on 1) The method according to claim 1, wherein the transferring the spoiler unit between the first position and the second position at the derived travel speed includes transferring the spoiler unit in an end range between the first position and the second position at a time-varying end travel speed, wherein the time-varying end travel speed decreases from the derived travel speed to zero. ### Claim 17 (depends on 15) The method according to claim 15, wherein the time-varying initial travel speed increases directly from zero to a minimum travel speed and then increases continuously from the minimum travel speed to the derived travel speed. ### Claim 18 (depends on 16) The method according to claim 16, wherein the time-varying end travel speed decreases from the derived travel speed to a minimum travel speed and then decreases directly to zero when the second position is reached.
