Problems solved by technology

However, this now leads to the fact that a greater steering or yaw moment cannot be achieved by braking on one side either.
Therefore, a redundant steering system configured in this way can only have a very limited effect on influencing the direction of travel

Embodiment Construction

[0040] figure 1 Shown in extremely schematic form are a rigid rear axle 1 of a motor vehicle 2 , a front steering axle 3 of the motor vehicle 2 with a first steering system 4 and a steering actuating device 5 in the form of a steering wheel 5 . Here, the two front wheels 6 are fastened to the wheel suspension 7 and connected to the steering axle 3 . The first steering system 4 is designed in the exemplary embodiment as a conventional steering system 4 , ie as a steering-knuckle steering mechanism, for example. The driving direction of the motor vehicle 2 can be influenced in a known manner by means of a conventional steering system 4 .

[0041] The invention provides that a redundant steering system is realized by adjusting the kingpin offset Rφ of the steering axle 3 (see figure 2 ), thus perpendicular to the figure 1 The component F acting in the direction of travel shown by the parallel arrows in L The conventional steering system 4 is applied in the region of at least...

Abstract

The invention relates to a method for influencing the direction of travel of a motor vehicle (2), wherein the motor vehicle (2) comprises a first steering system (4) comprising at least one steering axle with at least two wheels (6) (3) wherein the wheels (6) are connected to the steering axle (3) via wheel suspensions (7, 8) adjustable with actuators. According to the invention, a redundant steering system is realized by adjusting the kingpin offset (Rφ) of at least one of the steering axles (3), whereby in the region of at least one wheel (6) the Force component acting perpendicular to the direction of travel (F L ) is applied to the first steering system (4).

Description

technical field [0001] The invention relates to a method for influencing the driving direction of a motor vehicle according to the preamble of claim 1 . The invention also relates to a motor vehicle with a redundant steering system according to the preamble of claim 9 , and a computer program with a program code medium according to the preamble of claim 10 . Background technique [0002] Conventional steering systems for motor vehicles are well known from practice. With few exceptions, almost all motor vehicles today are equipped with so-called knuckle-type steering mechanisms. [0003] Recently, driver assistance systems have been increasingly used in motor vehicles to automate driving tasks. As examples, mention may be made of a distance control speed controller (Abstandsregeltempomat) or an adaptive cruise control system (Adaptive Cruise Control), a traffic jam assistance system (Stauassistent), a highway pilot system (Autobahnpilot) or a fully autonomous motor vehicle....
