Motorcycle Meter Layout for Early ACC Information Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers of straddle type vehicles, such as motorcycles, face difficulties in early and correct recognition of automatic traveling information due to the short inter-vehicle distance and frequent changes in traffic environment when using Adaptive Cruise Control (ACC) functions.
Innovation Solution
A straddle type vehicle is equipped with a vehicle speed information display unit and an automatic traveling information display unit positioned on the front side of the head pipe, where the vehicle speed information display changes linearly or in a curve with speed changes, and the automatic traveling information is displayed adjacent to the speed information, enhancing visibility and recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the automatic traveling information display unit is positioned in a conventional location, then the device layout is simple, but the driver cannot early recognize automatic traveling information due to short inter-vehicle distance and frequent traffic changes
Solution Approach 1:
The automatic traveling information display unit is positioned in the upward direction (vertical dimension) relative to the speed information display unit, rather than only in horizontal directions. This vertical arrangement allows the driver to recognize automatic traveling information earlier by utilizing the upper peripheral vision area, resolving the contradiction between early recognition and layout simplicity.
2Loss of information
If multiple display units are arranged to improve information visibility, then driver recognition is enhanced, but the meter device becomes bulky
Solution Approach 1:
By arranging the automatic traveling information display unit in the upward direction relative to the speed information display unit, the patent utilizes the vertical dimension for information placement. This allows multiple information types to be displayed without increasing horizontal or lateral space, preventing the meter device from becoming bulky while maintaining excellent visibility.
Solution Approach 2:
The display units are strategically positioned in specific local areas where the driver's vision naturally falls during normal riding. The speed information is in the lower area for peripheral detection, while automatic traveling information is in the upper area for focused recognition, optimizing information delivery without expanding overall device volume.
3Measurement precision
If the display position changes linearly or in a curve with speed changes, then speed information is clearly displayed, but the automatic traveling information must be positioned precisely to remain visible
Solution Approach 1:
The automatic traveling information display unit is positioned in the upward direction relative to the speed information display unit, creating a vertical separation that maintains their relative positional relationship regardless of how the speed display position changes horizontally or radially. This resolves the contradiction by making the positioning system more robust to speed variations.
