Vehicle Rut Tracking System for Curve Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively address road wear in the form of ruts caused by heavy goods traffic, which can lead to reduced driving safety and stability, especially when navigating curves.
Innovation Solution
A vehicle tracking system with a rut following mode that uses sensors and actuators to guide the vehicle's wheels into detected ruts, improving stability and adherence to optimal driving trajectories by influencing lane guidance based on rut detection signals, and adjusting for environmental parameters like wet road conditions.

Engineering Contradiction Analysis
1Stability of the object's composition
If vehicles drive uniformly on lanes without considering existing ruts, then road wear is distributed evenly, but driving stability is reduced when negotiating curves
Solution Approach 1:
The patent converts the harmful road defect (ruts) into a beneficial guidance feature. Instead of avoiding ruts as road damage, the system detects them and uses their longitudinal grooves to actively guide vehicle wheels, improving stability during curve negotiation and converting a negative road condition into a positive safety feature.
Solution Approach 2:
The patent inverts the conventional approach to lane guidance. Rather than guiding vehicles to drive uniformly in the center of lanes (avoiding ruts), the system inverts the strategy by deliberately guiding wheels to follow rut paths, transforming the guidance objective from 'avoid road defects' to 'exploit road features for stability'.
2Reliability
If the lane guidance system follows detected ruts by bringing wheels into overlap with them, then driving stability is improved, but the system complexity increases
Solution Approach 1:
The patent makes the lane guidance system multi-functional by enabling it to perform both conventional lane keeping (following lane markings) and rut following (following detected road grooves). The control device selects between these modes based on detected conditions, allowing a single system to handle multiple guidance scenarios without requiring separate dedicated systems for each function.
Solution Approach 2:
The patent introduces dynamic adaptability to the lane guidance system by enabling real-time switching between different guidance modes (conventional lane following vs. rut following). The system dynamically adjusts its behavior based on detected road conditions, making the guidance approach flexible rather than fixed, thereby managing complexity through adaptive intelligence.

AI summary
The invention relates to a method for the automatic lane guidance of a vehicle (100), which has at least two wheels on each side of the vehicle and a lane guidance system (4) with which at least one rut (10, 11) within a lane (2, 3) can be detected, wherein the lane guidance of the vehicle (100) can be influenced depending on the detection of at least one rut (10, 11), wherein the lane guidance system (4) has a rut-following mode in which, in the event that at least one rut (10, 11) has been detected, the lane guidance of the vehicle (100) is influenced by the lane guidance system (4) such that the vehicle (100) follows the at least one detected rut (10, 11) by bringing at least two wheels on at least one side of the vehicle into overlap with the at least one detected rut (10, 11).This is intended to achieve better driving stability of the vehicle (100) by guiding the wheels of the vehicle (100) through the grooves (10, 11), especially when driving through curves.
