Vehicle Control System Detecting Road Irregularities via Preceding Vehicle Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems fail to effectively address irregularities in road surfaces, which can lead to reduced driving safety and comfort by not adequately accounting for changes in road grip and vehicle control, especially at higher speeds.
Innovation Solution
A control system that uses environmental sensors, such as cameras and other technologies, to detect changes in the position of vehicles ahead, allowing for real-time adjustments in vehicle speed or settings to mitigate road surface irregularities by recognizing position changes and outputting warning signals or adjusting suspension and steering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver assistance systems monitor only lane position and basic environmental data, then the system complexity remains low, but the system cannot detect road surface irregularities that affect driving safety and comfort
Solution Approach 1:
The environmental sensor system is designed to perform multiple functions: it detects lane markings, other vehicles, and road surface irregularities using the same sensor infrastructure. The system processes environmental data to generate both lane position information and irregularity detection information, allowing one system to serve multiple safety functions without proportionally increasing complexity
Solution Approach 2:
The system uses the position changes of other vehicles as an intermediary indicator to infer road surface irregularities. Instead of directly detecting road conditions, the system observes how irregularities affect other vehicles' positions and uses this information to warn the driver, creating an indirect detection mechanism that enhances safety without requiring direct road contact sensors
2Productivity
If the vehicle speed increases, then the productivity and efficiency of transport improve, but the impact of road surface irregularities becomes more severe, reducing driving comfort and safety
Solution Approach 1:
The system performs preliminary detection of road surface irregularities by monitoring position changes of other vehicles before the own vehicle encounters them. By detecting irregularities in advance and warning the driver or adjusting vehicle settings, the system allows for preventive action to be taken, maintaining safety and comfort even at higher speeds where irregularities would otherwise have greater impact
3Measurement precision
If environmental sensors continuously monitor the area in front of the vehicle, then the detection of position changes in other vehicles improves, but the energy consumption and data processing requirements increase
Solution Approach 1:
The system maintains continuous monitoring of environmental data to detect position changes of other vehicles, which is essential for real-time irregularity detection. However, the continuous action is optimized by focusing processing only on relevant changes in environmental data that indicate position shifts, rather than processing all sensor data continuously, thereby maintaining detection precision while managing energy consumption
Data Source
AI summary
Control system, which is adapted for application in a vehicle and intended to recognize vehicles driving in front on the basis of environmental data which are obtained from at least one environmental sensor (110) disposed on the vehicle. The at least one environmental sensor (110) is adapted to provide an electronic controller (200) of the control system with the environmental data which reflect the area (115) in front of the vehicle. The control system is at least adapted and intended to detect another vehicle (alter) participating in traffic in front of the own vehicle (ego) with the at least one environmental sensor (110) during a predetermined time period or continuously and to recognize a position change of the other vehicle (alter). If a position change of the other vehicle (alter) is recognized, a signal (255) is output, which is suitable to warn a driver of the own vehicle (ego) of an irregularity in the road surface and/or to adjust a speed and/or a vehicle setting of the own vehicle (ego).
