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 A rigid rear axle 1 of a motor vehicle 2 , a front steering axle 3 of a motor vehicle 2 with a first steering system 4 and a steering device 5 in the form of a steering wheel 5 are shown in very schematic form. In this case, the two front wheels 6 are fastened to a wheel suspension 7 and connected to the steering axle 3 . In the exemplary embodiment, the first steering system 4 is designed as a conventional steering system 4 , ie, for example, a knuckle steering. The direction of travel of the motor vehicle 2 can be influenced in a known manner by means of a conventional steering system 4 .

[0041] The present invention stipulates: realize the redundant steering system in the following manner: adjust the kingpin offset Rφ of the steering axle 3 (see figure 2 ), and accordingly perpendicular to the figure 1 The force component F acting in the direction of travel indicated by the parallel arrows in L It is applied to a conventional steering system 4 in the ...

Abstract

The invention relates to a method for influencing the direction of travel of motor vehicles (2), the motor vehicle (2) comprising a first steering system (4) which in turn comprises at least one steering axle (3) with at least two wheels (6), the wheels (6) being connected to the steering axle (3) by wheel suspensions (7, 8) that can be adjusted by actuators. According to the invention, a redundant steering system is produced by adjusting a steering roller radius (R[phi]) of at least one of the steering axles (3), whereafter a force component (FL) acting orthogonally to the direction of travelis applied to the first steering system (4) in the region of at least one wheel (6).

Description

technical field [0001] The invention relates to a method for influencing the direction of travel 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 sufficiently known from practice. With few exceptions, almost all motor vehicles today are equipped with so-called knuckle steering. [0003] Recently, driver assistance systems are increasingly used in motor vehicles to automate the driving task. As examples, mention may be made of distance-regulating speed controllers (Abstandsregel tempomat) or adaptive cruise control systems (Adaptive Cruise Control), traffic jam assistance (Stau assist), highway pilot systems (Autobahnpilot) or fully autonomous motor vehicles. The higher the degree...
