Vehicle Curb Sensing and Prediction for Parking Availability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GPS systems cannot provide information on curb availability at a destination, making it difficult for vehicles to find available parking spaces as the number of vehicles increases.
Innovation Solution
A curb management system equipped with sensors, an electronic controller, and a wireless communication system that detects parked vehicles along a curb, determines curb management information, and transmits this data to a remote server for predicting curb availability, which is then shared with requesting vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS systems are used to provide geographical location information, then location accuracy is improved, but curb availability information is not provided
Solution Approach 1:
The patent combines GPS location functionality with curb availability detection by integrating sensors (cameras, LIDAR, ultrasonic sensors) with the existing GPS system. The sensor system detects parked vehicles and curb status, merging spatial location data with real-time curb occupancy information into a unified navigation system that provides both location accuracy and parking availability guidance.
Solution Approach 2:
The navigation system is enhanced to perform multiple functions: traditional GPS location tracking, real-time curb availability detection through various sensors, data transmission to remote servers, and receiving predictive curb availability information. This multi-functional system eliminates the need for separate dedicated curb detection systems.
2Productivity
If the number of vehicles traveling increases, then transportation capacity is improved, but finding curb availability becomes more difficult
Solution Approach 1:
The system performs preliminary detection of curb availability by continuously monitoring and transmitting real-time sensor data about parked vehicles and curb status to remote servers. This advance detection and data accumulation allows the system to predict future curb availability, enabling vehicles to plan routes and arrive at optimal parking locations before curbs become occupied.
Solution Approach 2:
The patent implements a feedback mechanism where sensor data from detecting vehicles is transmitted to remote servers, which analyze the data and send back predictive information about curb availability to requesting vehicles. This closed-loop feedback system continuously improves parking guidance accuracy as more data is collected, helping vehicles efficiently find available curbs even as traffic volume increases.
3Measurement precision
If real-time curb management information is transmitted to remote servers, then curb availability prediction accuracy is improved, but data transmission requirements increase
Solution Approach 1:
The system transmits data selectively rather than continuously - sending curb management information to remote servers based on detected changes in curb status or at optimized intervals. This partial transmission approach maintains prediction accuracy by reporting relevant updates while reducing overall data transmission volume and associated energy consumption compared to continuous streaming of all sensor data.

AI summary
A curb management system for a host vehicle includes a sensor, an electronic controller, and a wireless communication system. The sensor is configured to detect information relating to a presence of a parked vehicle along a curb of a road. The electronic controller is configured to determine curb management information based on the information detected by the sensor. The wireless communication system is configured to transmit the curb management information to a remote server and to receive a predicted curb availability from the remote server.
