Automated Driving Mode Activation Delay to Avoid Unavailable Mode Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems in vehicles often display error messages when an unavailable automated driving mode is selected, causing inconvenience to the driver.
Innovation Solution
A driving assistance system that includes a user interface and a processor unit to postpone the activation of selected automated driving modes based on their availability, using different time intervals for available and unavailable modes, allowing the user to select another mode before attempting activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the system immediately attempts to activate the selected automated driving mode, then the response speed is improved, but error messages occur when the mode is unavailable
Solution Approach 1:
The system checks the availability of the selected automated driving mode before attempting activation. This preliminary check prevents activation attempts when the mode is unavailable, thereby avoiding error messages while maintaining responsive user experience.
2Reliability
If the system waits longer before attempting activation, then error messages are reduced, but the response time increases
Solution Approach 1:
The system performs a preliminary availability check immediately upon mode selection, eliminating the need for delayed activation attempts. This approach reduces error messages without introducing unnecessary delays, as the check occurs before the user completes the selection process.
3Loss of information
If the system provides immediate feedback on mode availability, then user awareness is improved, but the complexity of the system increases
Solution Approach 1:
The system provides immediate feedback to the user about the availability of the selected automated driving mode through the user interface. This feedback mechanism informs users when their selected mode cannot be activated, allowing them to choose a different mode without causing error messages.
Data Source
AI summary
Methods, systems, and apparatuses for a driving assistance system of a vehicle are provided. A user input is received to select an automated driving mode from two or more different automated driving modes. A determination is made as to whether the selected automated driving mode is available when selected by the user input. If the selected automated driving mode is available when selected by the user input, activating the selected automated driving mode is postponed for a first time interval. Alternatively, if the selected automated driving mode is unavailable when selected by the user input, attempting to activate the selected automated driving mode is postponed for a second time interval that is longer than the first time interval.
