In-Vehicle Safety Visualization Alert Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers using in-vehicle navigation systems may overlook alerts from driver assistance systems due to increased cognitive load, as their attention is diverted to the navigation display, reducing the likelihood of noticing critical warnings like blind spot or collision warnings.
Innovation Solution
A safety visualization system that coordinates driver alerts with navigation systems by displaying alerts on the navigation map, side view mirrors, and instrument clusters, using a combination of graphics, icons, and light emitting diodes to ensure alerts are noticeable, even when the driver's attention is focused on navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver alerts are displayed using traditional locations (side view mirrors, instrument clusters), then the alert system maintains simplicity and reliability, but the driver may miss alerts when attention is focused on the navigation display
Solution Approach 1:
The patent combines multiple alert display locations (navigation display, side view mirrors, instrument clusters) into an integrated alert delivery system. This merging ensures that alerts are presented across multiple channels simultaneously, increasing the probability that the driver will notice critical warnings even when attention is divided between navigation and driving tasks.
Solution Approach 2:
The patent adds a new spatial dimension for alert presentation by overlaying alerts on the navigation display, which is a different dimensional plane from traditional alert locations. This creates a multi-dimensional alert delivery strategy that expands the driver's field of view for alert detection without requiring attention shifts to separate locations.
2Loss of information
If alerts are displayed on the navigation map, then alert visibility improves when driver attention is on navigation, but the navigation interface complexity increases
Solution Approach 1:
The patent applies local quality by placing alerts in specific, strategically chosen locations on the navigation display (such as near the vehicle icon or in corners of the map). This localized approach presents alert information precisely where the driver's attention is naturally focused on the navigation interface, without requiring redesign of the entire navigation system.
Solution Approach 2:
The patent segments the alert delivery function from the navigation display function, allowing alerts to be overlaid as distinct graphical elements on top of the navigation map. This segmentation enables independent control of alert presentation parameters (such as color, size, position) without affecting the underlying navigation interface design and complexity.
3Reliability
If multiple alert display locations are used simultaneously, then alert detection reliability improves, but the system complexity and cost increase
Solution Approach 1:
The patent makes the display system multi-functional by using the same display hardware (navigation display, side view mirrors, instrument clusters) for both their original purposes and as alert presentation surfaces. This universality allows the system to deliver alerts across multiple locations without requiring separate dedicated alert display devices, thereby reducing overall system complexity and cost.

AI summary
An in-vehicle safety visualization system (100) and method for coordinating driver alerts (110) with a navigation system (102). Driver alert systems are interfaced with a display (106) that is also used for depiction of navigation system images and information, allowing driver alerts (110) to be shown at a location in which the driver's attention is likely to be directed, in addition to the locations dictated by the driver alert systems.
