Problems solved by technology

The direction of travel is determined by an ambiguous mixing behavior; moreover, the steering control for feedback on the executed lateral guidance interventions can disturb the correlation between steering torque and steering angle, leading to inconsistent steering behavior

Embodiment Construction

[0033] figure 1 A schematic diagram illustrating the method according to the invention is shown. The driver 1 is located in the motor vehicle, wherein the driver, as known, can use a steering control device 2 , here the steering wheel, in order to influence a first transverse guidance actuator 3 , here the front axle steering. Arrows 4 pointing in both directions indicate that the steering device 2 is not only used as a means for actuating the first transverse guidance actuator 3 but also is clearly indicated by means of the steering angle of the steering device 2 , by actuating the steering device 2 In what direction and to what extent is the triggered lateral guidance intervention. This is achieved after the fact that, according to the double arrow 5 , there is a mechanical coupling between the steering device 2 and the first transverse guidance actuator 3 .

[0034] The steering device 2 and the first transverse guidance actuator 3 thus form a complete line for the transv...

Abstract

The invention relates to a method for operating a transverse guidance system (6) of a motor vehicle (13) for carrying out automatic transverse guidance interventions, said transverse guidance system comprising a first transverse guidance actuator ( 3) and a vehicle system (10) for setting a target roll angle, the first transverse guidance actuator being controlled by a steering device (2) operated by the driver, in particular a steering wheel, for performing transverse guidance interventions A second transverse guidance actuator (8), which does not act on the steering device (2) during a transverse guidance intervention, adjusts the motor vehicle ( 13) The revealed roll angle associated with at least one intervention parameter describing a lateral guidance intervention.

Description

technical field [0001] The invention relates to a method for operating a transverse guidance system of a motor vehicle for carrying out an automatic transverse guidance intervention, the transverse guidance system comprising a first transverse guidance actuator and a vehicle system for setting a target roll angle , the first transverse guidance actuator is controlled by a steering device operated by the driver, in particular a steering wheel. Furthermore, the invention relates to a motor vehicle. Background technique [0002] Known motor vehicles can be steered laterally by the driver, usually using a steering control device, in particular a steering wheel, which can be accessed by the driver. The steering wheel can be mechanically coupled directly to the transverse guidance actuator, usually the front axle steering; however, it is also possible that the input to the steering control device is measured by a steering sensor and this input is then converted into a correspondi...
