Vehicle Message Presentation Control for Driver Distraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information systems can distract drivers by presenting messages and control requests during critical driving situations, particularly affecting inexperienced or inattentive drivers, leading to hazardous conditions.
Innovation Solution
An information system that evaluates messages and control requests based on the current driving situation and driver status to determine their relevance and potential for distraction, adjusting presentation timing and method to minimize driver distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If messages and control requests are presented to the driver during driving, then the driver receives necessary information and can control the vehicle, but the driver becomes distracted and hazardous situations arise
Solution Approach 1:
The system dynamically adapts the presentation of messages and control requests based on the current driving situation and detected driver status. When the driver is in a critical driving task or showing signs of distraction, the system modifies or delays message presentation. When the driver is attentive and the driving situation is stable, the system presents messages normally, thus resolving the contradiction between information delivery and driver distraction.
Solution Approach 2:
The system continuously monitors driver status through sensors (eye tracking, attention detection) and driving situation through vehicle sensors, using this feedback to dynamically adjust message presentation. This closed-loop feedback mechanism allows the system to adapt to real-time conditions, presenting information only when it will not cause distraction, thereby resolving the contradiction between keeping the driver informed and preventing distraction.
2Quantity of substance
If multiple messages are presented simultaneously to the driver, then comprehensive information is provided, but the complexity of vehicle control increases and driver distraction worsens
Solution Approach 1:
Instead of presenting all messages simultaneously, the system selectively presents only the most relevant messages based on current driving context and driver status. This partial action approach ensures that critical information is delivered while avoiding information overload, thus reducing control complexity and driver distraction while maintaining comprehensive information delivery for critical matters.
Solution Approach 2:
The system segments messages by priority and relevance, presenting them in a sequential manner rather than all at once. Critical safety-related messages are presented immediately, while less urgent messages are delayed or omitted, breaking down the complex information stream into manageable segments that the driver can process without becoming overwhelmed.
3Loss of time
If messages are presented immediately without evaluation, then response time is reduced, but driver distraction and hazardous situations increase
Solution Approach 1:
The system performs preliminary evaluation of messages and driving situations before presenting information to the driver. By pre-assessing whether the current driving context can tolerate message presentation, the system avoids immediate presentation during critical moments, thus preventing hazardous situations while maintaining timely information delivery when safe.

AI summary
An information system for a vehicle includes a processor configured to: determine system information representing one or more than one message relating to an occupant of the vehicle and/or the vehicle and/or an environment of the vehicle; determine a current driving task of the vehicle; determine, using sensor data representing a state of the driver of the vehicle, driver information representing a physical and/or mental state of the driver; determine, using the current driving task and the driver information, message presentation information indicating, for each of the one or more than one message, whether the message is to be presented to the driver and/or how the message is to be presented to the driver and/or at what time the message is to be presented to the driver; and generate control instructions to control at least one component of the vehicle according to the message presentation information.
