Problems solved by technology

However, since the wheel first slips before the brakes intervene, that is, there must be slip, disadvantages in traction can occur despite the described treatment method, for example because the slipping wheel itself is buried and / or the wheel is located under the wheel. The ground is polished to further reduce the coefficient of friction between the wheels and the ground

Embodiment Construction

[0032] figure 1 A schematic diagram of a motor vehicle 1 is shown. The motor vehicle has a first axle 2 , for example a front axle, which has wheels 3 and 4 . Furthermore, motor vehicle 1 has a second axle 5 , for example a rear axle, which has wheels 6 and 7 . Wheels 3 and 4 of first axle 2 are operatively connected to one another via an axle differential 8 . Similarly, the wheels 6 and 7 of the second axle 5 are operatively connected to each other via an axle differential 9 . For example, the axle differential 8 has output shafts 10 and 11 , and the axle differential 9 has output shafts 12 and 13 . The wheels 3 are connected, preferably rigidly and / or permanently connected to the output shaft 10, the wheels 4 are connected, preferably rigidly and / or permanently connected to the output shaft 1, and the wheels 6 are connected, preferably rigidly and / or permanently is connected to the output shaft 12 and the wheel 7 is connected, preferably rigidly and / or permanently connec...

Abstract

The invention relates to a method for operating a driver assistance system of a motor vehicle (1). The method is characterized by the steps of: respectively acquiring the drive potentials of all drive wheels (3, 4) of at least one axle (3) of the motor vehicle (1); comparing these drive potentials; The power is used to actuate the braking device, so that the wheels (3) with a lower driving potential are braked.

Description

technical field [0001] The invention relates to a method for operating a driver assistance system of a motor vehicle. The invention also relates to a corresponding driver assistance system. Background technique [0002] Driver assistance systems serve to assist the driver of a motor vehicle, in particular in difficult driving and / or environmental conditions. For example, the driver assistance system is a drive slip control system or exists as such. The driver assistance system correspondingly implements a drive slip control, in which the braking device is used to brake in a targeted manner the wheels of the motor vehicle that are prone to slipping or the wheels that are slipping, by determining the load on said wheels braking force. If this wheel is operatively coupled to the other wheel via a differential gear, this braking would result in a greater drive torque being applied to the other wheel. However, since the wheel first slips before the brakes intervene, that is, ...
