Towing-State Display Control for Vehicle Surrounding Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies for vehicles do not adequately account for the change in detection state of surrounding information when towing a towed object, failing to provide clear visual cues to occupants about the presence of the towed object and associated changes in driving conditions.
Innovation Solution
A display control device that adjusts the display mode based on the presence of a towed object, including displaying a towed object image, shifting the vehicle image in the travel direction, indicating non-execution of specific driving assist functions, and showing changes in acceleration performance, thereby enhancing the occupant's understanding of the towing state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display unit shows standard vehicle images without modification, then the display is simple and clear, but the occupant cannot grasp the change in detection state when towing a towed object
Solution Approach 1:
The patent applies color changes to the detection state display to indicate towing conditions. When a towed object is detected, the system changes the color or visual appearance of the detection state indicators on the display unit, allowing occupants to immediately grasp the altered detection state without complex additional interfaces or controls
Solution Approach 2:
The patent segments the display information into distinct components: vehicle image, detection state indicators, and towing state indicators. This segmentation allows the system to present multiple types of information clearly and separately, enabling occupants to understand both the standard vehicle status and the special towing conditions without information overload
2Loss of information
If the display unit shows towed object image and shifted vehicle image, then the occupant can grasp the towing state clearly, but the display layout becomes more complex
Solution Approach 1:
The patent superimposes the towed object image and shifted vehicle image on the existing display layout rather than adding separate physical displays or controls. This dimensional overlay approach allows multiple information layers to coexist on the same display plane, conveying towing state information without significantly increasing physical display complexity

AI summary
The display control device includes a control unit configured to display, on a display unit, a detection state of a vehicle image indicating the vehicle when viewed from a virtual viewpoint and a detection state of the surrounding information based on surrounding information of a vehicle surroundings detectable by the vehicle, and to change a display mode of the detection state when the vehicle is in a towing state in which the vehicle is towing a towed object.
