Vehicle Collision Avoidance Path Display for Driver Alert Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information display systems for vehicles become inconvenient for drivers when multiple obstacles are present, as they display alerts for all obstacles individually, overwhelming the driver.
Innovation Solution
An information display device comprising a surrounding environment detector, vehicle information acquirer, predictor, and avoidance path provider that detects surrounding objects and vehicle information, predicts potential collisions, and displays an avoidance path to mitigate collisions, reducing driver inconvenience by focusing on critical alerts rather than individual obstacle alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If alerts for all obstacles are displayed individually, then the driver is informed about all surrounding objects, but the driver becomes overwhelmed and experiences inconvenience
Solution Approach 1:
The patent segments the information display by priority levels. Instead of displaying all obstacle alerts uniformly, the system divides alerts into different segments based on collision risk: high-risk obstacles that require immediate attention are displayed prominently, while low-risk obstacles are either grouped or omitted. This segmentation allows the driver to focus on critical information without being overwhelmed by all surrounding objects.
Solution Approach 2:
The patent extracts only the most critical information from the complete set of obstacle data. By using collision risk assessment algorithms, the system extracts and displays only those obstacles that pose a genuine threat to vehicle safety, filtering out irrelevant or low-priority obstacles. This extraction principle reduces information overload while maintaining safety-critical awareness.
2Reliability
If multiple obstacle alerts are displayed, then comprehensive situational awareness is achieved, but driver attention is fragmented and reaction time is reduced
Solution Approach 1:
The patent applies local quality by providing different levels of information detail in different display regions or contexts. Critical obstacles that require immediate reaction are highlighted with prominent visual indicators in key display areas, while less critical information is placed in peripheral or less prominent positions. This spatial differentiation of information quality allows the driver to quickly identify and respond to the most urgent threats.
Solution Approach 2:
The patent performs preliminary assessment and filtering of obstacle information before presenting it to the driver. The system pre-evaluates all detected obstacles using collision risk algorithms, prediction models, and priority classification in advance of display. This preliminary action ensures that only pre-validated, high-priority obstacles are presented to the driver, reducing cognitive processing time and enabling faster reaction.
3Reliability
If all surrounding objects are monitored and alerted, then complete safety coverage is provided, but the system complexity and computational load increase
Solution Approach 1:
The patent implements partial action by monitoring all surrounding objects but providing detailed alert information only for a subset of critical obstacles. The system performs complete environmental scanning and risk assessment on all detected objects, but selectively generates detailed alerts only for obstacles exceeding predefined risk thresholds. This approach maintains comprehensive safety coverage while reducing the complexity of alert generation and information processing.

AI summary
An information display device includes a surrounding environment detector, a vehicle information acquirer, a predictor, an avoidance path provider, and an information display. The surrounding environment detector detects position relevant information related to a position of at least a surrounding object in a surrounding environment of a vehicle. The vehicle information acquirer detects vehicle information including a speed and a steering direction of the vehicle. The predictor predicts a contact of the vehicle with the surrounding object, based on the position relevant information and the vehicle information. When the predictor has predicted that there is a possibility of the contact of the vehicle with the surrounding object, the avoidance path provider assumes an avoidance path for avoiding the contact, based on the position relevant information and the vehicle information. The information display displays the avoidance path.
