Embodiment Construction

[0016] figure 1 A motor vehicle 1 is shown in a simplified top view, with a drive 2 and a braking system 3 .

[0017] The drive mechanism 2 has a drive shaft 4 with two drive wheels 5 , 6 , which are operatively connected to each other via a differential gear 7 . According to another exemplary embodiment not shown here, it can also be provided that the drive mechanism 2 can be decoupled from the drive shaft 4 by means of a clutch or the like. Furthermore, the differential gear 7 is coupled to an electric drive 8 .

[0018] Brake system 3 has wheel brakes 9 , 10 which are each assigned to one of drive wheels 5 , 6 . In particular, wheel brakes 9 , 10 can be actuated hydraulically. For this purpose, the brake system 3 has an antilock brake system 11 hydraulically connected to the wheel brakes 9 , 10 in order to hydraulically actuate the wheel brakes to generate a braking force. The antilock braking system 11 is designed here as an ABS braking system, which actuates the wheel...

Abstract

A method for operating a motor vehicle (1), which has at least one electric drive motor (8), which is connected / connectible to at least one drive axle (4) having two drive wheels (5, 6), wheel brakes (9, 10) assigned to the drive wheels (5, 6) being controlled by an anti-lock braking system (11) for building up respectively one ABS braking force for a braking process. The invention provides for varying an ABS braking force buildup on one of the drive wheels when the other of the drive wheels (5, 6) of the drive axle (4) exhibits a critical slip.

Description

technical field [0001] The invention relates to a method for operating a motor vehicle having at least one electric drive which is connected / connectable to at least one drive shaft with two drive wheels, wherein for For the braking process, the wheel brakes assigned to the drive wheels are actuated by an antilock braking system for correspondingly forming the ABS braking force. [0002] Furthermore, the invention relates to a device for such a motor vehicle and a corresponding motor vehicle. Background technique [0003] Methods, devices and motor vehicles of the type mentioned at the outset are already known from the prior art. Increased electrification of the drive train of a motor vehicle requires that the same safety systems as in conventional drive trains with a combustion engine also function in motor vehicles with an electric drive. Conventional safety systems, such as in particular anti-lock braking systems (ABS), are therefore used even in drives with electric dri...
