Vehicle Control Device Lane Change Display Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated driving systems, occupants feel uncomfortable due to the inability to determine the appropriate lane for the vehicle to travel on, leading to a lack of security and confidence during lane changes.
Innovation Solution
A vehicle control device and method that includes a display to show the current lane and a reference lane, allowing the system to switch driving modes and control speed and steering to facilitate lane changes based on user input and predetermined conditions, such as entering a highway, while displaying the road layout to inform the occupant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated driving control is implemented without lane change information display, then driving automation is achieved, but occupant security and confidence deteriorate due to inability to ascertain the determined lane
Solution Approach 1:
The system provides visual feedback to the occupant by displaying the determined reference lane on the display device. The display controller causes the display to show a first image depicting the current lane and a second image depicting the reference lane, allowing the occupant to verify the automated system's lane determination and maintain confidence in the automated driving control.
Solution Approach 2:
The display device acts as an intermediary between the automated driving controller and the occupant. It translates the internal lane determination data into visual representations (first image of current lane, second image of reference lane) that the occupant can understand, bridging the gap between automated control and human awareness.
2Reliability
If lane change information is displayed to improve occupant awareness, then occupant security is enhanced, but device complexity increases due to additional display control functions
Solution Approach 1:
The display controller is designed to perform multiple functions: it controls the display of the first image (current lane), the second image (reference lane), and various text messages (lane change prompts, determination results). This multi-functionality reduces the need for separate dedicated display components for each type of information, thereby managing complexity while providing comprehensive lane change information.
3Loss of information
If the system determines reference lane and displays it during automated driving, then occupant awareness is improved, but information processing complexity increases
Solution Approach 1:
The information display is segmented into distinct components: a first image showing the current lane, a second image showing the reference lane, and separate text message areas for lane change prompts and determination results. This segmentation allows the determiner to process and output different types of lane information independently, reducing the complexity of integrated information processing while ensuring complete occupant awareness.

AI summary
A vehicle control device includes a display configured to display information, an inputter to which a user's operation is input, a driving controller configured to control at least one of a speed and steering of a vehicle, a determiner configured to determine a lane in which the vehicle is present when a first operation that allows a lane change by the vehicle is input to the inputter as a reference lane, and a display controller that is configured to cause the display to display a first image depicting a road on which the vehicle is present and a second image depicting the reference lane which are superimposed.
