Example Embodiment

[0019] If the road section 1 has no rutting (Spurrille), or only rutting without changing the predetermined trajectory T, the direction control system not shown here is within a certain period of time-here the period t 0 To t 1 Representation-Directional control of vehicles such as trucks in the usual way. That is to say, the direction control system then controls the wheels of the vehicle in a usual manner to be a constant distance along the road section shown by dashes without obvious rutting, for example, a predetermined trajectory T that defines the center of the road.

[0020] If from time t 1 Since the obvious or deep ruts 2 and 3 (respectively limited by the side limit lines 2a, 2b or 3a, 3b) that are shown by solid lines appear on the road section 1, the direction control system of the present invention is Intervention: Specifically, for example, the sensor device of the direction control system on the vehicle side is used to detect or obtain significant changes in the rot...

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...
