Vehicle Sensor Network for Dynamic Road Condition Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems lack efficient means to provide real-time, dynamic road condition updates to drivers, particularly in situations where bandwidth is limited, and fail to effectively integrate sensor data from vehicles to improve route recommendations based on environmental and dynamic road conditions.
Innovation Solution
A vehicle communication system that utilizes sensors and transceivers to detect and share road conditions, such as traffic lights and construction, with other vehicles, using a threshold-based confirmation mechanism to ensure accuracy, and integrates this data into navigation maps to recommend alternative routes, enhancing driver awareness and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time traffic information is shared across the network, then navigation accuracy and driver awareness are improved, but communication bandwidth is consumed and system complexity increases
Solution Approach 1:
The patent extracts only the essential traffic information elements needed for navigation decisions, filtering out redundant data. The system identifies and transmits only critical parameters such as traffic light states, construction zones, and speed limit changes, rather than sharing all possible traffic data, thus reducing communication overhead while maintaining navigation accuracy.
Solution Approach 2:
The traffic information is segmented into different priority levels and categories. Critical safety-related information (e.g., red traffic lights, construction zones) is separated from less important data. This segmentation allows the system to prioritize transmission of essential information, reducing overall communication bandwidth requirements while ensuring critical data is always available.
2Loss of information
If all traffic information is transmitted to the network, then comprehensive route optimization is achieved, but communication bandwidth is exceeded
Solution Approach 1:
The system extracts only the most relevant traffic information parameters that directly impact route optimization and driver safety. By filtering out redundant and less critical data, the patent reduces the volume of transmitted information while maintaining the quality and usefulness of navigation recommendations.
Solution Approach 2:
Instead of transmitting complete and exhaustive traffic information, the system transmits a partial set of critical parameters sufficient for effective navigation decisions. This partial action approach provides adequate route optimization without overwhelming the communication bandwidth, achieving a practical balance between information completeness and transmission efficiency.
3Reliability
If dynamic road condition updates are provided continuously, then driver safety is enhanced, but energy consumption increases
Solution Approach 1:
The navigation system updates dynamic road condition information at periodic intervals rather than continuously. This periodic action reduces energy consumption by the sensor and processing components while still providing timely updates on traffic lights, construction zones, and speed limit changes, maintaining driver safety without excessive power usage.
Solution Approach 2:
The system dynamically adjusts the update frequency based on the criticality of road conditions and current driving context. For normal conditions, updates occur at standard intervals to conserve energy. When critical conditions are detected, the update frequency increases automatically, ensuring safety is maintained while minimizing overall energy consumption during stable periods.

AI summary
Systems, methods, and apparatuses related to vehicle navigation systems are described. A first vehicle may encounter an environmental condition. The first vehicle may be in communication with a second vehicle having a route that is proximate the proximate condition. The first vehicle may detect an environmental condition using a sensor on the first vehicle and determine certainty of the environmental condition above a threshold. The second vehicle may be notified about the environmental condition detected by the first vehicle based on an expectation that the second vehicle may encounter the environmental condition. The second vehicle may re-route in response to the environmental condition, and/or integrate the environmental condition in the navigation map.
