Vehicle Speed Regulation Using Turn Beacons Without Navigation Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed regulation systems for motor vehicles rely heavily on navigation data, which may not be accessible in all situations, such as tunnels, limiting their effectiveness in regulating vehicle speed during turns.
Innovation Solution
A system and method utilizing external beacons with communication devices and sensors to transmit information about turn configurations and conditions to the vehicle, allowing the vehicle's computer to adjust speed independently of navigation data, using signals from presence and speed sensors and additional beacons positioned along the turn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speed regulation systems use navigation data to regulate vehicle speed during turns, then speed regulation can be achieved, but the system fails when navigation data is not accessible (e.g., in tunnels)
Solution Approach 1:
The patent introduces beacons as intermediary devices positioned along the roadway that directly communicate turn configuration data to the vehicle. These beacons serve as mediators between the road infrastructure and the vehicle's speed regulation system, eliminating the need for navigation data and ensuring reliable operation in all environments including tunnels.
Solution Approach 2:
The system divides the speed regulation functionality into separate components: beacons positioned at specific locations along the roadway that transmit turn configuration data, and vehicle-based receivers that process this data. This segmentation allows the navigation system to be replaced while maintaining speed regulation capability.
2Reliability
If the system uses only navigation data for speed regulation, then the system structure is simple, but it cannot provide speed regulation when navigation data is unavailable
Solution Approach 1:
Beacons are introduced as external intermediary devices that store and transmit turn configuration data directly to vehicles. This shifts the data storage function from the vehicle's navigation system to roadside infrastructure, ensuring data availability without significantly increasing vehicle complexity.
Solution Approach 2:
The patent extracts the turn configuration data storage and transmission function from the vehicle's navigation system and places it in external beacons. This extraction allows the speed regulation system to operate independently of the navigation system while maintaining access to necessary road geometry data.
3Adaptability or versatility
If beacons store fixed turn configuration data, then the system is simple to implement, but it cannot adapt to vehicles with different speeds
Solution Approach 1:
The beacon system is enhanced with presence and speed sensors that detect approaching vehicles and dynamically adjust the transmitted turn configuration data based on vehicle speed. This dynamic adaptation allows the same beacon to provide optimized guidance for vehicles traveling at different speeds without requiring multiple fixed configuration sets.
Solution Approach 2:
The system implements feedback through sensors that detect vehicle presence and speed, then use this information to adjust the turn configuration data transmitted by the beacon. This closed-loop approach ensures that each vehicle receives appropriately tailored speed guidance based on its actual operating conditions.
