Automated Driving Display Distinguishing Lane and Trajectory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving technologies face challenges in intuitively conveying the driving assist state to vehicle occupants, making it difficult to distinguish between the recommended route and trajectory, especially in scenarios involving nearby vehicles.
Innovation Solution
A display system that includes a first display unit showing the driving assist state, a second display unit showing the road on which the vehicle travels, and a display control unit that highlights the recommended lane in a specific color and displays the target trajectory in a narrower region, allowing occupants to visually recognize the driving assist state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the displayed route is shown without visual distinction between recommended lane and trajectory, then the display is simple, but it is difficult to determine whether the displayed route is a route for reaching a destination or a trajectory in consideration of nearby vehicles
Solution Approach 1:
The patent applies local quality by using different visual properties (color, line style, width) for different parts of the displayed route. The recommended lane is displayed with one visual style while the trajectory is displayed with another, allowing occupants to distinguish between the two without adding overall system complexity.
Solution Approach 2:
The patent uses color changes to differentiate between the recommended lane and the trajectory. By assigning distinct colors to each route element, the system provides clear visual information about the driving assist state without requiring complex additional display mechanisms.
2Ease of operation
If the recommended lane and target trajectory are displayed with the same visual properties, then the display is simple, but it is difficult to understand a driving assist state for the host vehicle from displayed content
Solution Approach 1:
The patent makes different parts of the displayed route have different visual properties. The recommended lane and trajectory are distinguished through variations in color, line style, or width, enabling occupants to easily recognize the driving assist state while maintaining display simplicity.
Solution Approach 2:
The patent segments the displayed route into distinct components (recommended lane and trajectory) with different visual characteristics. This segmentation allows occupants to understand the driving assist state by visually distinguishing between the destination route and the trajectory considering nearby vehicles.

AI summary
A display system includes: a first display unit (400) that displays an image indicating a driving assist state of a vehicle which includes an automated driving state; a second display unit (400) that displays an image that resembles a road on which the vehicle travels; and a display control unit (120) that allows the second display unit to display approximately the entire region of a region corresponding to a recommended lane applied to a control unit that performs the automated driving in a predetermined color, and allows a target trajectory generated by the control unit that performs the automated driving to be displayed in a region narrower than the recommended lane.
