Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous driving vehicles, drivers face difficulties in selecting and executing secondary tasks during autonomous driving states due to the inability to easily determine the conditions under which these tasks can be performed within the available time, leading to inefficient use of travel time.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle travels to a destination during autonomous driving, then the driver can perform a second task, but the driver cannot easily determine the conditions and available time for executing the second task
Solution Approach 1:
The patent segments the autonomous driving period into discrete time intervals (task possible time) during which second tasks can be executed. The second task extracting unit divides the overall autonomous driving duration into specific executable time slots, making the information structure organized and easily accessible to the driver through the user interface.
Solution Approach 2:
The system performs preliminary extraction and analysis of task possible time before the driver needs to select a second task. The second task extracting unit pre-calculates and identifies executable time windows based on route information and autonomous driving predictions, so that when the driver accesses the user interface, the information is already prepared and ready for selection.
2Reliability
If the driver selects a second task without proper time estimation, then the driver may execute inappropriate tasks, but determining task possible time requires complex analysis
Solution Approach 1:
The patent introduces a second task extracting unit as an intermediary component that bridges the gap between route information and second task selection. This unit automatically performs the complex time analysis and extracts task possible time, serving as a mediator that simplifies the interaction between the driver and the autonomous driving system while ensuring accurate time estimation.
Solution Approach 2:
The system performs self-service by automatically extracting and determining task possible time without requiring manual input or complex driver analysis. The second task extracting unit autonomously analyzes route information and autonomous driving predictions to identify executable time windows, eliminating the need for the driver to perform complex time calculations.
3Adaptability or versatility
If the system provides detailed task possible time information, then the driver can make better task selections, but the user interface becomes more complex
Solution Approach 1:
The patent extracts only the essential information (task possible time) needed for second task selection and presents it through the user interface, rather than displaying all available data. The second task extracting unit isolates and extracts the critical time window information, allowing the interface to remain simple while providing the necessary flexibility for task execution.
Data Source
AI summary
An execution of a second task of a driver is assisted in cooperation with a user interface in an autonomous driving state in which a vehicle is an execution entity of a driving task. The second task is extracted, which is properly executable within task possible time estimated as time in which the second task is executable in a route to a destination of the vehicle. The second task extracted by the second task extracting unit is suggested through the user interface.
