Mobile Device Display Shielding for Autonomous Driving Takeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers may not notice alarms during autonomous driving if they are concentrating on their mobile devices, potentially due to wearing earphones, and existing systems fail to effectively redirect their attention back to driving.
Innovation Solution
An autonomous driving system with a mobile device case that includes a display cover capable of switching between visible and shielded states, either through an opening and closing mechanism or a variable transmittance screen, to obscure the mobile device display when the driver is requested to take over driving, ensuring attention is redirected to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver concentrates on operating the mobile device during autonomous driving, then the driver can use the mobile device functions, but the driver may not notice alarms or take over driving when needed
Solution Approach 1:
The system preemptively obscures the mobile device display when it detects that the driver needs to take over driving or when an alarm is issued. This preliminary action prevents the driver from being distracted by the mobile device at critical moments, thereby maintaining driving safety while allowing mobile device usage during normal autonomous operation
Solution Approach 2:
The mobile device case acts as an intermediary between the driver and the mobile device. It provides a physical barrier (display cover) that can block the display while still allowing the driver to hold and operate the mobile device. This intermediary mechanism enables the system to control information visibility without preventing mobile device functionality
2Ease of operation
If the driver is wearing earphones, then the driver can listen to audio content, but the driver may not notice alarm sounds from the vehicle
Solution Approach 1:
The system preemptively obscures the mobile device display when it detects that the driver needs to take over driving or when an alarm is issued. This preliminary action prevents the driver from being distracted by the mobile device at critical moments, thereby maintaining driving safety while allowing mobile device usage during normal autonomous operation
Solution Approach 2:
The system uses detection mechanisms (such as cameras or sensors) to monitor whether the driver is wearing earphones or appears distracted. Based on this feedback, the system automatically adjusts the display visibility by opening or closing the display cover, creating a closed-loop control system that adapts to the driver's state
3Loss of information
If the mobile device display remains visible during autonomous driving, then the driver can monitor mobile device information, but the driver's attention may be diverted from the vehicle
Solution Approach 1:
The display cover is designed to be dynamically adjustable, transitioning between open and closed states based on driving conditions. The system opens the display cover during normal autonomous operation to allow mobile device visibility, and closes it when the driver needs to take over or when alarms are issued, creating a dynamic adaptation to operational needs
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively redirects the driver's attention to the driving task by obscuring the mobile device display, ensuring prompt attention to vehicle operations during autonomous driving transitions, and prevents initiation of autonomous driving without the mobile device case attachment.
Implementation Method 1
The display cover may include a variable transmittance screen covering the display of the mobile device. The display is switched from the visible state to the shielded state by changing a transmittance of the variable transmittance screen.
Data Source
AI summary
An autonomous driving system connected communicably to a mobile device of a driver or to a mobile device case attached to the mobile device, and configured to perform autonomous driving control. the autonomous driving system comprises a display cover of the mobile device case, capable of switching a display of the mobile device between a visible state and a shielded state. The display of the mobile device is switched from the visible state to the shielded state by controlling the mobile device or the mobile device case, when the driver is requested to perform a driving operation of a vehicle during the autonomous driving control.
