Vehicle Passenger Information Interface for Driver Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems primarily focus on informing the driver, leaving co-drivers and passengers without sufficient information about the driver's awareness and the traffic situation, which can lead to discomfort and reduced confidence during vehicle operations, especially in semi-autonomous driving scenarios.
Innovation Solution
A vehicle system equipped with an estimation unit to assess driver parameters and traffic situation parameters, generating relevant information for co-drivers and passengers through a dedicated interface, allowing them to gauge the driver's capability to handle the current situation, including awareness, attention, and preparedness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If driver interface is positioned for optimal driver viewing, then driver distraction is reduced, but passenger visibility of driving information deteriorates
Solution Approach 1:
The visual information system is segmented into two separate display units: a driver display positioned at the dashboard for optimal driver viewing with reduced distraction, and a passenger display positioned where passengers can view simplified information. This segmentation allows each user to have optimized visibility without compromising the other.
Solution Approach 2:
Different visual qualities and information depths are provided at different locations: the driver display shows comprehensive, detailed information optimized for driving tasks, while the passenger display shows simplified awareness information optimized for passenger viewing. This resolves the contradiction by providing location-appropriate information quality.
2Reliability
If driver assistance systems focus on driver task support, then driving safety is improved, but passenger confidence and comfort deteriorate
Solution Approach 1:
The system segments information delivery into two functional streams: one focused on driving safety support for the driver, and another focused on awareness and confidence building for passengers. This segmentation allows the system to maintain its primary safety function while simultaneously addressing passenger confidence needs.
Solution Approach 2:
The passenger interface acts as an intermediary that translates complex driver assistance system operations into simplified awareness information for passengers. This intermediary function allows passengers to gain confidence without interfering with the driver's safety-critical information processing.
Data Source
AI summary
The invention is related to a method and vehicle comprising a driver seat and at least one passenger seat for providing a co-driver and/or fellow passenger with information on a currently experienced driving situation. In an estimating unit at least one driver parameter is estimated. The driver parameter describes at least one aspect of current driving action performed by the driver of the vehicle. Furthermore, in the estimating unit at least one traffic situation parameter is estimated describing at least an aspect of the traffic situation encountered by the vehicle. From the at least one driver parameter and/or from the at least one traffic situation parameter then information that is related to the currently experienced driving situation is generated. This information is then output to a co-driver and/or fellow passenger via a dedicated interface unit.
