Problems solved by technology

[0007] It should be avoided that the vehicle driver is not used to the driving behavior of the motor vehicle and is in a dangerous situation due to such a changeover of the driving mode or feels that the driving of the motor vehicle is uncomfortable, for example, feels unsafe

Embodiment Construction

[0032] By "starting the vehicle" in step S10, the driver of the vehicle or the vehicle control system determines in step S12 in which drive mode the drive should start. The drive mode may be, for example, rear-wheel drive, front-wheel drive or all-wheel drive. In principle, any two drive modes differ in whether or not at least one wheel of the motor vehicle is driven. In this case, the motor vehicle should be able to implement at least two of the above-mentioned driving modes. Adapted to the driving mode, the track and camber are set in step S14, and the wheel loads on the wheels are set according to step S16, for example by means of so-called stabilizers—that is to say on both sides of the vehicle with the wheels On springs coupled to each other - set the stiffness accordingly.

[0033] It is then checked in step S18 whether the drive mode has changed. Said changes may be caused by the driver or by the automatic control system.

[0034] If the drive mode has not changed, ...

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.

Description

technical field [0001] The invention relates to a method for operating a motor vehicle with the characteristic that it can be driven in at least two drive modes, wherein the modes differ from one another with regard to whether at least one wheel of the motor vehicle is driven. The invention also relates to a motor vehicle. Background technique [0002] It is known that the drive mode is, for example, "front-wheel drive", "rear-wheel drive" or "all-wheel drive". [0003] Furthermore, for the motor vehicle it is assumed that the motor vehicle has a so-called active chassis, ie adjustments can be made on the chassis system during continuous operation of the motor vehicle. [0004] In order for a motor vehicle driver to be able to drive a motor vehicle safely, the driver must expand his sense of vehicle and his driving characteristics to the motor vehicle. It is important, for example, for the driver of the vehicle to be aware of the so-called inherent steering behavior of the...
