Overtaking Assistance Using Lead Vehicle Route Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively prevent risky overtaking maneuvers, particularly on country and federal roads, as they do not account for the intentions of the lead vehicle to change lanes or routes, leading to potential traffic accidents.
Innovation Solution
A method and driver assistance device that utilize route information from the lead vehicle to recommend or advise against overtaking maneuvers based on its expected route changes, using wireless communication and self-learning observation modules to determine if the lead vehicle intends to leave the route, thereby avoiding unnecessary and dangerous overtaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing overtaking assistance systems provide recommendations based only on road geometry and static map data, then the system complexity remains low, but the reliability of overtaking recommendations deteriorates because the systems cannot detect lead vehicle intentions to change lanes or routes
Solution Approach 1:
The patent introduces route information from the lead vehicle's navigation system as an intermediary element that mediates between the follower vehicle's overtaking decision and the lead vehicle's actual behavior. This route information serves as a predictor of the lead vehicle's future lane changes or route deviations, allowing the overtaking assistance system to make more reliable recommendations without directly monitoring the lead vehicle's sensors or communication systems.
Solution Approach 2:
The system performs preliminary analysis of the lead vehicle's planned route before an overtaking maneuver is initiated. By evaluating the route information in advance, the system can predict whether the lead vehicle will change lanes or deviate from the current route, allowing the follower vehicle's driver to make informed overtaking decisions before committing to the maneuver, thereby improving reliability without requiring complex real-time monitoring.
2Reliability
If the system continuously monitors and processes route information from the lead vehicle to provide accurate overtaking recommendations, then the reliability improves, but the loss of time for processing information and providing recommendations increases
Solution Approach 1:
The system applies partial monitoring by selectively evaluating route information based on specific trigger conditions rather than continuously processing all data. The overtaking assistance system activates detailed route analysis only when the follower vehicle approaches within a certain distance of the lead vehicle and when an overtaking maneuver is being considered, reducing processing time while maintaining accuracy for critical decision moments.
Solution Approach 2:
The system performs preliminary evaluation of route information in advance when the follower vehicle is still at a distance from the lead vehicle. By assessing the lead vehicle's planned route early, the system prepares overtaking recommendations ahead of time, reducing the processing time required when the actual overtaking decision needs to be made, thus balancing accuracy with response time.
3Productivity
If the system provides detailed route information and overtaking recommendations to the follower vehicle driver, then the productivity of traffic flow improves by reducing unnecessary overtaking attempts, but the device complexity increases due to additional communication and processing requirements
Solution Approach 1:
The patent extracts only the essential route information needed for overtaking decisions from the lead vehicle's navigation system, rather than transmitting or processing complete navigation data. The overtaking assistance system selectively extracts relevant parameters such as planned lane changes, route deviations, and timing information, reducing communication and processing requirements while maintaining the ability to improve traffic flow efficiency by preventing unnecessary overtaking attempts.
