Data Transmitter Adjusting Display Mode for Autonomous Driving Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with autonomous driving systems, drivers engaged in secondary activities may not be aware of changes in driving conditions that require their attention, as they are not alert to surroundings that necessitate a shift from level 3 to level 2 autonomous driving.
Innovation Solution
A data transmitter mounted on the vehicle determines the confidence score of object detection from area images and transmits these images to a terminal via a communication network, adjusting the display mode based on the confidence score to draw attention when the score is low, ensuring the driver is informed of potential dangers during secondary activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle operates at level 3 autonomous driving where the driver need not be alert, then the driver can engage in secondary activities, but the driver becomes unaware of dangers in the surroundings that cause changes in autonomous driving level
Solution Approach 1:
The system implements feedback by transmitting area images captured by the surrounding area sensor to the driver's terminal device. This allows the driver to view the surrounding environment on their terminal while engaged in secondary activities, providing continuous visual feedback about potential dangers and enabling awareness of conditions that may require attention without requiring constant driver alertness
Solution Approach 2:
The terminal device acts as an intermediary between the vehicle's surrounding area sensor and the driver. It receives area images from the sensor via communication networks and displays them to the driver, serving as a mediator that delivers environmental information to the driver in a convenient format without requiring the driver to directly monitor surroundings
2Reliability
If the driver is required to be alert to driving conditions, then the driver can respond to changes in autonomous driving level, but the driver cannot engage in secondary activities
Solution Approach 1:
The system provides visual feedback of the surrounding environment to the driver through the terminal device, allowing the driver to maintain awareness of dangers while engaging in secondary activities. The area images transmitted to the terminal enable the driver to monitor surroundings passively without requiring active alertness
3Reliability
If the driver repeats actions such as checking surroundings to stay alert, then the driver may become aware of dangers, but the driver's attention is repeatedly diverted from secondary activities
Solution Approach 1:
The system provides continuous visual feedback of the surrounding environment displayed on the driver's terminal device. This allows the driver to monitor dangers passively without repeatedly interrupting secondary activities to check surroundings, thereby maintaining both safety awareness and productivity in secondary tasks
Data Source
AI summary
A data transmitter is to be mounted on an autonomous driving vehicle. The data transmitter determines whether a confidence score indicating the degree of reliability of detection of the object from the area image is greater than a predetermined confidence score threshold; transmits, when the confidence score regarding the area image is greater than the confidence score threshold, the area image or a face image representing the face of a driver to a terminal, together with a first setting for displaying the area image or the face image on the terminal in first mode; and transmits, when the confidence score is less than the confidence score threshold, the area image to the terminal, together with a second setting for displaying the area image on the terminal in second mode that draws more attention of a user of the terminal than the first mode.
