Proactive Driver Assistance Voice Query System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver-assistance systems in vehicles do not effectively reduce cognitive load on drivers during automated driving modes, leading to potential distractions and safety concerns, as they often require manual interaction and visual attention for operation.
Innovation Solution
A method where a driver-assistance system monitors the driving situation and proactively provides voice-based queries and instructions to the driver, adjusting its functions autonomously based on retrieved data, allowing the driver to focus on the road while maintaining control and safety, even in ambiguous situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver-assistance system requires manual interaction and visual attention for operation, then the system can maintain control and safety, but the driver's cognitive load increases and driver distraction occurs
Solution Approach 1:
The patent replaces manual mechanical interaction and visual attention requirements with voice-based acoustic interaction. The system processes voice commands and provides voice feedback, allowing the driver to operate assistance functions without taking hands off the steering wheel or eyes off the road, thereby maintaining safety while reducing cognitive load and driver distraction
2Ease of operation
If the driver-assistance system provides proactive voice-based queries and instructions, then driver cognitive load is reduced and convenience is increased, but the system complexity increases
Solution Approach 1:
The driver-assistance system proactively monitors the driving situation and independently determines when driver input or information would be beneficial. The system initiates voice-based queries and instructions without requiring the driver to first activate functions or ask questions, thereby reducing cognitive load while the proactive monitoring and determination logic manages the underlying system complexity
3Ease of operation
If the driver-assistance system operates in automated driving modes, then driver distraction is minimized, but the driver may become disengaged and less attentive to the road
Solution Approach 1:
The system provides proactive voice-based feedback to the driver during automated driving modes, including queries about driving intentions, information about the driving situation, and requests for driver input when appropriate. This feedback mechanism keeps the driver engaged and attentive to the road while still operating in automated modes, preventing disengagement without requiring constant manual intervention

AI summary
The assistance system of a motor vehicle includes a driver-assistance system for monitoring a driving situation of the motor vehicle and a control device for determining at least one course of option resulting from the monitored driving situation, by taking into consideration data that can be retrieved by the control device independently of a user input to the assistance system. The assistance system also includes an output device for outputting a query to provide to a driver a function of the assistance system corresponding to a course of action. The assistance system also includes a detection device for detecting a response reaction of the driver. The control device provides the function of the assistance system depending on the detected response to reduce the cognitive load of the driver.
