Driver Display Lane Highlighting for Autonomous Route Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems fail to adequately present recommended lanes during autonomous driving, lacking sufficient guidance for the vehicle's travel path.
Innovation Solution
A display control device that displays a host vehicle image and lane images, distinguishing recommended lanes from others using different display modes, and adjusts vehicle images and route indications based on travel mode and congestion information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional navigation displays are used, then the system is simple, but the recommended lane information is insufficient and unclear
Solution Approach 1:
The display screen is divided into multiple regions: a first region displaying the recommended lane with enhanced visual characteristics, and a second region displaying other lanes with standard visual characteristics. This segmentation allows the system to highlight critical information (recommended lane) without completely redesigning the entire display system.
Solution Approach 2:
Different display regions are assigned different visual qualities to convey different levels of importance. The first region (recommended lane) uses distinctive visual characteristics such as different colors, brightness, or patterns compared to the second region (other lanes), enabling drivers to quickly identify the recommended path without overwhelming the entire display.
2Ease of operation
If multiple display regions with different visual characteristics are used, then lane recommendation clarity is improved, but the display system becomes more complex
Solution Approach 1:
The display system dynamically adjusts visual characteristics of different regions based on real-time driving conditions, travel modes, and congestion levels. The display control unit modifies the appearance of vehicle images and lane markings according to the current situation, allowing the system to adapt without requiring multiple fixed display configurations.
Solution Approach 2:
The system changes display parameters such as color, brightness, size, and position of visual elements based on travel mode and congestion information. For example, vehicle images in congested areas may be displayed with different characteristics, and the recommended lane may be highlighted more prominently during certain travel modes, enabling flexible control without hardware changes.
3Measurement precision
If detailed congestion information is displayed for each lane, then travel guidance accuracy is improved, but information overload may occur
Solution Approach 1:
The system extracts and highlights only the most critical congestion information related to the recommended lane and alternative lanes. Rather than displaying all available data, the display control unit selectively presents congestion levels, travel times, and other relevant metrics only for lanes that affect the driver's routing decision, reducing information overload while maintaining guidance accuracy.
Solution Approach 2:
The system provides detailed congestion information selectively - full detail for the recommended lane and partially detailed or summarized information for other lanes. This partial action approach ensures that critical information is complete and accurate while avoiding the presentation of all possible data points that would create information overload.

AI summary
The display control device includes a display control unit that displays, on a display unit provided around a driver's seat of the host vehicle, a host vehicle image imitating the host vehicle and a lane image imitating a lane on which the host vehicle can travel, and displays, in a different manner, a first region including the lane image indicating a recommended lane on which the host vehicle is recommended to travel among the lanes, and a second region including the lane image indicating the lane other than the recommended lane.
