Vehicle Display Control for Traffic Regulation Range Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display control systems fail to accurately recognize the end position of a valid range indicated by traffic regulation marks, leading to continuous display of regulation information even after the vehicle has left the valid range.
Innovation Solution
A vehicle display control device and method that recognizes traffic regulation marks, specifies valid regulation ranges, and controls a display to switch information presentation based on predetermined conditions, ensuring appropriate display of regulations information even when the valid range cannot be specified.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system displays regulations information continuously, then the driver can always see the regulation content, but the display cannot be switched off when the vehicle leaves the valid range because the end position cannot be recognized
Solution Approach 1:
The system performs preliminary actions by specifying the valid range of regulation before the vehicle actually leaves it. By predicting or pre-determining the end position of the valid range based on map data or other information, the system can prepare to switch off the display at the appropriate moment, preventing the information from being displayed inappropriately after the vehicle has left the regulation area.
2Ease of operation
If the system switches off display based on estimated valid range, then the display can be appropriately controlled, but the display may be switched off prematurely or too late if the valid range is not accurately specified
Solution Approach 1:
The system introduces an intermediary mechanism by using map data or external information sources as a mediator between the vehicle position and the regulation validity determination. This intermediary allows the system to estimate the valid range when direct measurement is not available, enabling display control while acknowledging the limitation in precision. The intermediary data helps bridge the gap between incomplete direct measurement and the need for accurate display timing.
Data Source
AI summary
A vehicle display control device includes a memory and a processor coupled to the memory. The processor is configured to: recognize a traffic regulation mark provided on a traveling path of a car, the traffic regulation mark indicating traffic regulation; specify a valid regulation range used as a valid range of regulation indicated by the traffic regulation mark based on the recognized traffic regulation mark; and control a display device mounted on the car to display regulations information on a display area, the regulations information including contents of regulation indicated by the recognized traffic regulation mark. The processor is configured to switch displaying the regulations information into another upon satisfying a predetermined condition in a case where the valid regulation range is not specified.
