Driver Assistance Moderation for Partial Automation Trust Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems in vehicles, particularly at Level 2 automation, face safety issues due to drivers building excessive trust in automation, leading to insufficient monitoring and potential inattentiveness during partially automated driving maneuvers.
Innovation Solution
A method and system that outputs moderation signals to drivers after a predetermined number of high-performance automated functions, requesting feedback or manual confirmation for subsequent functions, and adjusts signals to surroundings to prevent excessive trust, using sensors, computing apparatus, and information systems to monitor and moderate driver attentiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver assistance system operates autonomously without driver moderation, then the ease of operation is improved, but the safety deteriorates due to lack of driver oversight
Solution Approach 1:
The system applies partial automation by requiring driver confirmation only in specific cases (after predetermined number of successful operations) rather than continuously. This partial moderation maintains ease of operation for routine functions while ensuring safety through periodic driver oversight, resolving the contradiction between automation convenience and safety.
Solution Approach 2:
Driver moderation is applied periodically rather than continuously, allowing the system to operate autonomously for predetermined numbers of functions while periodically requiring driver confirmation. This periodic intervention maintains safety without significantly compromising ease of operation.
2Reliability
If the driver assistance system requires driver confirmation for every function, then the safety is improved, but the productivity deteriorates due to increased driver workload
Solution Approach 1:
Driver confirmation is required only partially - specifically after predetermined numbers of successfully performed functions rather than for every single function. This partial confirmation requirement maintains safety through periodic oversight while preserving driving efficiency by allowing uninterrupted automated operation during normal functioning.
Solution Approach 2:
The system maintains continuous automated operation for predetermined numbers of functions without interruption, ensuring productivity is preserved. Driver confirmation is only required periodically, allowing the useful automated action to continue uninterrupted while still maintaining safety through periodic driver engagement.

AI summary
Methods and systems are provided for operating a driver assistance system of a vehicle. A plurality of partially automated functions are performed using the driver assistance system during operation of the vehicle. In the partially automated functions, longitudinal guidance and/or transverse guidance of the vehicle are and/or is regulated, and/or information that describes surroundings of the vehicle is output and/or a signal is output to the surroundings using the driver assistance system. Following a predetermined number of performed partially automated functions, a moderation signal is output to a driver of the vehicle for a following function that can be performed in a partially automated manner using the driver assistance system. When the moderation signal is output, the driver is asked for feedback regarding the following function.
