Automated Driving Control Modes for Safe Feedback Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems for automated driving and parking lack the ability to effectively acquire data on system performance and user feedback, leading to potential disadvantages and risks during the introduction of new functionalities.
Innovation Solution
A vehicle system designed with a first and second operating mode, where the second mode decouples the effectiveness of interventions from vehicle guidance to acquire operating and feedback data, allowing for data collection without causing flawed or unexpected actions, and enabling data utilization for further development and optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a vehicle system executes automated driving functionalities with full intervention effectiveness, then the driving automation performance is improved, but the risk of flawed or unexpected actions increases
Solution Approach 1:
The system performs preliminary data collection in a second operating mode before full automated driving deployment. Sensor data, operating data, and user feedback are gathered in advance to identify and correct system flaws before they can cause harmful interventions in actual automated driving operations.
Solution Approach 2:
The system implements continuous feedback loops where user feedback and operating data from the second mode are collected and used to improve the automated driving system. This feedback mechanism allows the system to learn from real-world operations and reduce the risk of unexpected actions in the first operating mode.
2Adaptability or versatility
If the vehicle system collects comprehensive data on system performance and user feedback, then the development and optimization capability is improved, but the system complexity increases
Solution Approach 1:
The data collection system is segmented into distinct operational modes. The second operating mode is specifically dedicated to data collection for development purposes, while the first mode handles actual automated driving. This segmentation allows comprehensive data gathering without complicating the core automated driving functionality.
Solution Approach 2:
The vehicle system is designed with multi-functionality, where the same sensor infrastructure and processing units serve both automated driving operations and data collection for development. This universal design avoids duplicating hardware and reduces overall system complexity while enabling comprehensive data gathering.
3Loss of information
If the vehicle system operates in a second mode with decoupled intervention effectiveness, then the data acquisition capability is improved, but the operational efficiency decreases
Solution Approach 1:
The system maintains continuous operation in both modes, with the second operating mode running parallel data collection activities alongside or between first mode operations. This ensures that data acquisition is an ongoing process rather than an intermittent interruption, minimizing impact on overall operational efficiency.
Solution Approach 2:
The second operating mode creates a virtual copy of the automated driving system that operates with decoupled intervention effectiveness. This copy processes sensor data and generates the same operational outputs without actually executing physical interventions, allowing comprehensive data collection without sacrificing real driving productivity.

AI summary
A vehicle system has a first operating mode and a second operating mode. The first operating mode is configured to execute a functionality of the vehicle system in driving mode based on acquired sensor signals and to operate the vehicle in an at least partially automated manner through interventions in vehicle guidance based on the result of the executed functionality. The second operating mode is configured to change a degree of the effectiveness of the interventions in the driving mode and/or a degree of the effectiveness of an operation decoupled from the vehicle guidance, and, when executing a functionality of the vehicle system with a changed degree of the effectiveness of an intervention in the vehicle guidance and/or a changed degree of the effectiveness of an operation decoupled from the vehicle guidance, to acquire operating data of the vehicle and/or feedback data from the user of the vehicle.
