Vehicular Display Marker for Adaptive Cruise Control Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular display devices struggle to inform drivers whether adaptive cruise control is active when the preceding vehicle moves outside the limited display area, making it difficult for drivers to determine if the control is being maintained during curved road navigation.
Innovation Solution
A vehicular display device with a preceding vehicle detector, determiner, and display processor that continuously displays a marker image in the peripheral area of the vehicle's widthwise side edge where the preceding vehicle is located, adjusting the image's size, shape, color, and frequency based on its position relative to the display area to ensure the driver is aware of the adaptive cruise control status.

Engineering Contradiction Analysis
1Loss of information
If the marker image is displayed only within the limited display area, then the display remains clear and uncluttered, but the driver cannot determine whether adaptive cruise control is active when the preceding vehicle moves outside the display area
Solution Approach 1:
The patent extends the display from the traditional two-dimensional display area onto the three-dimensional windshield surface. When the preceding vehicle moves outside the display area, the marker image is projected onto the windshield in the spatial direction corresponding to the vehicle's position, allowing continuous visualization beyond the original display boundaries without adding complex additional components
Solution Approach 2:
The windshield serves as an intermediary medium between the display system and the driver. By projecting the marker image onto the windshield when the preceding vehicle is outside the display area, the system uses the windshield's transparent properties to maintain driver awareness without obstructing the view of the actual preceding vehicle

AI summary
A vehicular display device detects the position of a preceding vehicle which a vehicle is following while traveling, and displays a marker image corresponding to the detected position of the preceding vehicle in a display area. The vehicular display device determines whether the preceding vehicle is located on an inner side of vehicle widthwise side edges of the display area or on outer sides of the vehicle widthwise side edges, based on the position of the preceding vehicle. When the preceding vehicle is located on the outer side of one of the vehicle widthwise side edges of the display area, the vehicular display device continues to display the marker image in a peripheral portion of the side edge on the outer side of which the preceding vehicle is located.
