Problems solved by technology

This kind of directional control further seriously exacerbates the aforementioned unfavorable control characteristics, resulting in continuous control intervention, resulting in very unstable driving, which makes the driver feel uncomfortable
Moreover, this directional control can cause serious damage to the tires

Embodiment Construction

[0019] If the road section 1 has no ruts (Spurrilles), or only ruts without changing the predetermined trajectory T, the steering control system, not shown here 0 to t 1 Presentation - Steering control of a vehicle, such as a truck, in the usual manner. That is to say, the directional control system then steers the wheels of the vehicle at a constant distance from a predetermined trajectory T which defines, for example, the center of the road along the section of the road shown here with a dash without significant ruts in the usual manner.

[0020] If from time t 1 From the appearance of obvious, i.e. deeper, ruts 2, 3 (delimited by lateral delimiting lines 2a, 2b or 3a, 3b respectively) shown here with solid lines on the road section 1, the directional control system of the present invention is To intervene: specifically, for example, with the sensor system of the vehicle-side directional control system, a significant change in the angle of rotation and / or wheel restoring f...

Abstract

The invention relates to a lane guidance method for a vehicle, in particular for a commercial vehicle. The vehicle is equipped with a direction control system which actively performs direction control. The vehicle moves inside a lane of a predetermined track which is predetermined on the basis of detected lane parameters. According to the invention, the direction control system respectively summates the predetermined track or detects at least one specified track parameter as a track real value and compares the track real value with at least one predetermined track reference value. When there is a deviation between the track real value and the track reference value, the predetermined track is changed to make the wheels of the vehicle basically travel inside the tracks (2,3) of the lane. An independent claim is also included for a tracking system for executing the method.

Description

technical field [0001] The invention relates to a method for directional control of a vehicle, in particular a truck, according to the preamble of claim 1 . The invention also relates to a directional control system according to the preamble of claim 8 . Background technique [0002] Steering control systems are known from the prior art which keep the vehicle within the lane by means of continuous steering interventions. In this case, the lateral position within the lane can be adapted as a function of the road conditions (Straβenverlauf) or the surrounding traffic situation (Umgebungsverkehr). [0003] A method and a device for controlling the direction of a vehicle are known, for example, from DE 130 16 413 A1, in which lateral lane-defining markings are detected and evaluated in order to correct the direction of motion of the vehicle. In particular, a braking intervention is performed on at least one vehicle wheel in order to correct the direction of motion of the vehic...
