Problems solved by technology

[0004] This indirect acquisition of wheel dimensions, including snow chains if necessary, is costly and imprecise
Manual input directly via the on-board computer is also costly and error-prone

Embodiment Construction

[0025] figure 1 A steering mechanism of a passenger car according to an embodiment of the invention is shown schematically with two wheels 1 steered by means of racks 3 and accommodated in wheel housings 5 ​​. In order to move the rack 3, the electric motor 2 of the steering drive is engaged with it, and the electric motor 2 assists in supporting the steering action of the steering rod (not shown) operatively connected to the steering wheel, or disengages it from the steering wheel according to the acquired steering operation of the steering wheel. The racks move independently.

[0026] In addition to a steering drive in the form of an electric motor 2 , the steering mechanism includes in particular a controller 4 to which it is signal-connected. The controller 4 turns on the motor 2 and obtains from the motor 2 in particular information about the current adjustment stroke, such as the position of the rack 3 or the angle of rotation of the motor 2, and the magnitude or amount...

Abstract

The invention relates to a wheeled vehicle with a controller (4), and relates to an electrical limitation of a travel of a steering device (1-4), in particular of a passenger car. The method includes (S10) reading-in of a stored vehicle configuration into the controller (4) of the steering device (1-4), and (S20) deriving an adjusting value limitation from the read-in vehicle configuration. The method includes electrically limiting travel (40) of the steering device through the controller (4) based on the derived adjusting value limitation.

Description

technical field [0001] The invention relates to a method for electrically limiting the adjustment stroke of a steering mechanism of a wheeled vehicle, especially a car, and a steering mechanism for implementing the method. Background technique [0002] The free space of the wheel in the wheel housing limits the possible degree of steering of the steered wheels, in particular to avoid contact of the steered wheel with the wheel housing, thus limiting the degree of steering of the steered wheels. [0003] A steering mechanism for a motor vehicle is known from DE 10 2008 055 900 A1, in which the maximum steering angle of the steering wheels can be adjusted electrically. According to the detected external boundary conditions, the maximum steering degree of the steering wheel can be automatically matched. For this purpose, the control / regulation unit uses the Electronic Stability Program (ESP) to determine whether to use snow chains or not depending on the slipping situation. W...
