Vehicle Control Device Displaying Non-Selected Traveling Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with automatic operation control, users may feel distrust when the target traveling line set by the system differs from their perceived line, leading to concerns about the validity of the automatic operation.
Innovation Solution
A vehicle control device that includes an environment recognition unit and an automatic operation control unit, which selects a target traveling line based on surrounding environment information and displays non-selected traveling lines along with the reason for their non-selection, helping users understand the validity of the chosen path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the automatic operation control unit selects a target traveling line based on surrounding environment information without displaying alternative paths, then the automatic operation control can function efficiently, but the user may feel distrust when the selected line differs from their perceived line
Solution Approach 1:
The display device provides feedback to the user by showing alternative traveling lines that were considered but not selected, along with reasons for their non-selection. This feedback mechanism allows users to understand the automatic operation control unit's decision-making process, thereby maintaining trust while preserving operational efficiency.
Solution Approach 2:
The display device acts as an intermediary between the automatic operation control unit and the user. It translates the control unit's internal decision process into visible information showing alternative paths and selection reasons, facilitating user understanding without interfering with the automatic control's efficient operation.
2Reliability
If the system displays all alternative traveling lines and selection reasons, then user trust is enhanced, but the device complexity and information processing load increase
Solution Approach 1:
The system extracts only the essential information needed to build user trust: the top alternative traveling lines and their non-selection reasons. By selecting and displaying only this relevant subset rather than all possible alternatives, the system maintains transparency without excessive complexity.
Solution Approach 2:
The display provides detailed information locally at the points where alternatives were considered, rather than uniformly displaying all information throughout the interface. This allows comprehensive transparency where needed while keeping the overall display simple and manageable.

AI summary
Provided is a vehicle control device mounted on a vehicle including an environment recognition unit and an automatic operation control unit. The environment recognition unit is configured to acquire information on surrounding environment around the vehicle, and provide the automatic operation control unit with the information on the surrounding environment. The automatic operation control unit is configured to acquire select one proposed traveling line, as a target traveling line of the vehicle, from a plurality of proposed traveling lines, on a basis of the information on the surrounding environment, and allow the vehicle to travel along the target traveling line. The vehicle control device is configured to acquire provide display of an image of one or more non-selected traveling lines other than the proposed traveling line selected as the target traveling line from the plurality of proposed traveling lines, together with display of an image of the target traveling line.
