Vehicle Driving Support Device Prioritizing HUD and Meter Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving support devices face challenges in effectively providing critical information to drivers due to limited display space and visibility issues, particularly when information needs to be prioritized for immediate recognition during vehicle operation.
Innovation Solution
A driving support device that utilizes a combination of head-up and meter displays to prioritize critical information for immediate recognition, with the head-up display showing high-priority information and the meter display showing lower-priority information, and dynamically adjusts display content based on steering wheel operation to maintain visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If driving support information is displayed on the meter display, then the driver can recognize the information, but the driver needs to change their line of sight and the information may be hidden by the steering wheel during steering operations
Solution Approach 1:
The patent introduces a head-up display (HUD) as an intermediary device that projects driving support information onto the windshield, allowing the driver to view information without changing line of sight or removing hands from the steering wheel, thus resolving the contradiction between information visibility and operational convenience
2Ease of operation
If driving support information is displayed on the head-up display, then the driver does not need to change their line of sight, but the display space is limited and imposes strict restrictions on information provision
Solution Approach 1:
The patent segments the display system into two parts: head-up display for high-priority, critical information and meter display for detailed, non-urgent information. This segmentation allows the HUD to maintain its advantage of not requiring line of sight changes while the meter display provides additional space for comprehensive information presentation
3Adaptability or versatility
If multiple types of driving support information are provided, then the driver receives comprehensive support, but the limited display space cannot accommodate all information simultaneously
Solution Approach 1:
The patent divides driving support information into multiple categories and displays different types on different devices based on priority and detail level, enabling comprehensive information provision within limited display space
Solution Approach 2:
The patent utilizes the temporal dimension by dynamically switching display content based on driving conditions, notification priority, and driver state, allowing comprehensive information to be presented sequentially across different time points rather than requiring simultaneous display

AI summary
A limited display space provided in a vehicle is used to effectively provide driving support information to a driver. When a notification condition for driving support information is satisfied, an information processing unit generates the driving support information, and determines whether the driving support information is prioritized driving support information or non-prioritized driving support information. When the driving support information is the prioritized driving support information, the information processing unit transmits an output request for the driving support information to an HUD ECU. As a result, the driving support information is displayed on a head-up display. On the other hand, when the driving support information is the non-prioritized driving support information, the information processing unit transmits an output request for the driving support information to a meter ECU. As a result, the driving support information is displayed on a meter display.
