Vehicle Display Control for Driving Support Level Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems struggle to accurately convey the level of driving support to occupants, leading to potential misinterpretation of displayed images, as they often overlap and fail to distinguish between the system's support level and requests for occupant action.
Innovation Solution
A vehicle control system that includes a display unit to show distinct images representing the degree of driving support and requested actions, using separate positions and animations to clearly indicate the current support level and requested operations, such as steering wheel and foot positions for manual driving tasks.

Engineering Contradiction Analysis
1Area of stationary object
If images indicating driving support level and requested actions are displayed in contact with each other, then the display is compact and space-efficient, but the occupant cannot clearly distinguish between system support level and action requests, leading to incorrect recognition
Solution Approach 1:
The display is segmented into distinct regions: a first display region for showing the driving support level (with images of operational units and human parts) and a second display region for showing requested actions (with icons and text). This spatial segmentation prevents confusion between system status and action requests while maintaining compact overall display.
2Device complexity
If the same display position is used for both driving support level images and action request images, then the display is simple and easy to implement, but the occupant cannot determine whether the image represents current support level or a request for action
Solution Approach 1:
The solution adds a spatial dimension to the display by creating separate display regions (first display region for support level, second display region for action requests). This dimensional separation allows the system to convey multiple types of information simultaneously without confusion, improving reliability while maintaining relatively simple control logic.
3Ease of manufacture
If images of operational units and human parts are displayed without clear separation, then the display design is simple, but it is difficult to distinguish whether an operation by the occupant is permitted or being requested
Solution Approach 1:
Different regions of the display are assigned different functions and visual characteristics. The first display region uses images of operational units and human parts to indicate driving support level, while the second display region uses distinct icons and text to indicate requested actions. This local differentiation ensures that each region's purpose is clear, making it easy for occupants to understand what is permitted versus what is requested.

AI summary
A vehicle control system includes a display unit configured to display an image, a vehicle control unit configured to perform a driving support by different degrees, and a display control unit configured to display an image indicating an action requested for an occupant at a display position corresponding to an image related to the degree of the driving support on the display unit.
