Abstract
A motor vehicle can have multiple drive modes, for example rear wheel drive, four wheel drive, front wheel drive. Here, an active chassis device is used to make different adjustments, for example with respect to the toe-in angle and the camber angle, of a wheel or else with respect to wheel loads as a function of the drive load. As a result, the driving behaviour can be matched in each case in an optimum way to the drive mode, or conversely can be configured in such a way that changing the drive mode does not have a perceptible effect for the driver.

A method for operating a motor vehicle, which is drivable in one of at least two drive modes, which differ from one another with regard to at least one wheel of the motor vehicle regarding whether the at least one wheel it is driven or not, comprising:
- automatically changing a setting of a chassis device of the motor vehicle in response to changing the drive mode so that a variable which describes a self-steering behavior of the motor vehicle corresponds to a predetermined value, said predetermined value being a function of the drive mode.
A motor vehicle which is drivable in one of at least two drive modes, which differ from one another with regard to at least one wheel of the motor vehicle regarding whether the wheel is driven or not, comprising:
- a chassis device;
- and
- a control device which automatically changes at least one setting at the chassis device in response to a change of the drive mode, so that a variable which describes a self-steering behavior of the motor vehicle corresponds to a predetermined value, said predetermined value being a function of the drive mode.
