Automated Driving Image Display System for Driver Anxiety Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated driving systems, drivers experience anxiety due to a lack of clarity about the vehicle's present state and future behavior, as they do not visually perceive how the vehicle recognizes its surroundings and predicts its future actions during automatic steering and acceleration/deceleration control.
Innovation Solution
An image display system comprising a first processor, a second processor, and a comparator that generates and displays present and future position information of a vehicle and its surroundings, using behavior estimation results and real-time data from sensors, allowing a display device to show both current and predicted states side by side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated driving control is implemented without visual feedback, then automation level is improved, but driver anxiety increases due to lack of clarity about vehicle behavior
Solution Approach 1:
The patent creates visual copies (images) of the vehicle's present state and future predicted state, displaying them on a screen to provide the driver with visual feedback about automated driving behavior without interfering with the automation itself
Solution Approach 2:
The image display system acts as an intermediary between the automated driving control system and the driver, translating internal vehicle state data and future behavior predictions into visual representations that the driver can understand
2Loss of information
If present state information is displayed without future behavior prediction, then driver awareness of current state is improved, but driver anxiety persists due to inability to predict future actions
Solution Approach 1:
The system performs preliminary visualization of future vehicle behavior and surrounding object positions before the actual future moment occurs, allowing the driver to anticipate upcoming actions and reduce anxiety about unpredictable automated decisions
3Reliability
If detailed visual information about future behavior is provided, then driver confidence is improved, but system complexity increases
Solution Approach 1:
The patent segments the complex information about future vehicle behavior into distinct visual elements: future vehicle position, future positions of surrounding objects, and temporal comparison between present and future states, making the information more digestible for the driver

AI summary
An image display system includes a first processor, a second processor, and a comparator. The first processor acquires a behavior estimation result of a vehicle, and generates future position information after a predetermined time passes of the vehicle based on the behavior estimation result. The second processor acquires present information about the vehicle, and generates present position information on the vehicle and a peripheral object based on the acquired information. The comparator compares the future position information on the vehicle and the present position information on the vehicle and the peripheral object, and generates present image data indicating present positions of the vehicle and the peripheral object and future image data indicating future positions of the vehicle and the peripheral object. Further, the comparator allows a notification device to display a present image based on the present image data and a future image based on the future image data together.
