Claim 10:
11. A method for operating a spoiler apparatus according to claim 1, the method comprising:
controlling the spoiler apparatus with a control and regulating unit in accordance with system parameters that are designed in such a way that an adjustment of the spoiler blade is carried out both in a speed-dependent manner and in accordance with a degree of retardation of the vehicle, and adjusting the spoiler blade in defined steps, with at least one step for a driving operation of the vehicle and a further step in a case of a maximum retardation of the vehicle, and thereby:
adjusting the spoiler blade between steps, including from a higher step to a lower step and from a lower step to a higher step, only when a relevant speed range has been maintained for a predefined time of at least 5 seconds;
when the vehicle enters into an emergency braking situation with a maximum retardation, adjusting the spoiler blade directly into a further step that is associated with a maximum adjusting angle and a maximum air resistance, independently of a current step to be recorded of the spoiler blade.
