Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for creating virtual reality road images for vehicle training do not effectively allow drivers to anticipate how vehicle control systems, including drive assistance and autonomous driving, will operate in various road situations, lacking a method to provide advance warning of potential operational discrepancies.
Innovation Solution
A display apparatus and method for vehicles that generates a trial course based on map information and virtual destinations, calculates trial results for vehicle control operations, and displays alert information to occupants, enabling them to recognize how vehicle control will operate in different road scenarios through a trial image and notification images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If vehicle control systems execute autonomous driving control based on road situations, then the vehicle can operate without conforming to occupant intention, but the occupant cannot anticipate or understand how the vehicle control will operate in various road situations
Solution Approach 1:
The system performs preliminary actions by generating trial courses and calculating trial results before actual autonomous driving. The trial course generation unit creates virtual trial courses based on map information, and the trial result calculation unit computes how the vehicle control would operate on these courses. This preliminary simulation allows the occupant to understand the vehicle control's intended operations before they occur in real driving, thereby preventing information loss about control behavior.
Solution Approach 2:
The system introduces an intermediary mechanism - the trial image display system - that mediates between the autonomous vehicle control system and the occupant. The trial course generation unit, trial result calculation unit, and image generation unit work together to create visual representations (trial images) that show the occupant how the vehicle control will operate. This intermediary translates complex control decisions into understandable visual information, bridging the gap between automated control and occupant comprehension.
2Loss of information
If the system provides detailed information about vehicle control operations to the occupant, then the occupant can understand control behavior, but the system complexity increases
Solution Approach 1:
The system creates simplified copies of the actual driving scenario through trial courses. Instead of showing the occupant raw control data or complex system operations, the system generates trial courses that are simplified representations of the road situation, and trial images that copy the essential visual information about control operations. This copying approach provides necessary information to the occupant while keeping the system relatively simple by using standardized visualization methods.
Solution Approach 2:
The system segments the information provision process into distinct functional units: the trial course generation unit handles course creation, the trial result calculation unit computes control operations, and the image generation unit creates visual displays. This segmentation allows each unit to perform its specific function efficiently without requiring the entire system to become overly complex. The modular structure enables information provision while maintaining system manageability.

AI summary
A display apparatus for vehicle is provided in a vehicle capable of executing vehicle control including drive assistance control and autonomous driving control. The display apparatus includes an ECU configured to: generate a trial course for the vehicle control based on map information and a virtual destination of the vehicle; acquire statistical information regarding a past operation of the vehicle control in which past operation information of the vehicle control and a position on a map are stored in association with each other; calculate a trial result regarding an operation of the vehicle control according to a trial setting value regarding the vehicle control when the vehicle is caused to virtually travel along the trial course; generate a trial image for causing an occupant of the vehicle to recognize alert information of the statistical information in advance; and cause a display unit of the vehicle to display the trial image.
