Method and control device for operating a motor vehicle having multiple air-guiding devices
First Claim
1. A method for operating a motor vehicle having multiple air-guiding devices that include at least having a rear diffuser and a rear spoiler, the method comprising:
- selecting one of an economical driving mode where air resistance of the motor vehicle is minimized, a performance driving mode in which an optimum lift balance in terms of driving dynamics is set at the front axle and rear axle and a sport driving mode where a front-axle downforce and a rear-axle downforce of the motor vehicle are maximized;
transferring the rear-end diffuser into a first deployed rear diffuser position and substantially simultaneously transferring the rear spoiler into a first deployed rear spoiler position when the economical driving mode is selected;
transferring the rear diffuser into a second deployed rear diffuser position and transferring the rear spoiler is into a second deployed rear spoiler position when the performance driving mode is selected; and
transferring the rear diffuser into a retracted rear diffuser position and transferring the rear spoiler into a third deployed rear spoiler position when the sport driving mode is selected.

Abstract
A method for operating a motor vehicle (10) includes selecting one of an economical driving mode in which an air resistance is minimized, a performance driving mode in which an optimum lift balance is set at the front and rear axles, and a sport driving mode in which front and rear axle downforces are maximized. The rear diffuser (12) and the rear spoiler (12) are transferred into first deployed positions when the economical driving mode is selected. The rear diffuser (12) and the rear spoiler (13) are transferred into second deployed positions when the performance driving mode is selected. The rear diffuser (12) is transferred into a retracted rear diffuser position and the rear spoiler (13) is transferred into a third deployed rear spoiler position when the sport driving mode is selected.
