Lane Information Database Using Multi-Vehicle Driving Statistics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Establishing lane information for a network of intricately connected roads across a national scale is inefficient, requiring vehicles equipped with various sensors and GPS systems to drive on every lane, making it impractical to implement.
Innovation Solution
An apparatus and method that collect and compile driving information from multiple vehicles using mobile communication, which includes a map information storing unit, a driving information collecting unit, an accumulating and compiling statistics unit, and a controlling unit to generate lane information based on digital map data and vehicle statistics, allowing for the creation of a lane information database without needing to drive on every road.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles equipped with sensors and GPS drive on every lane to establish lane information, then lane information coverage is improved, but implementation efficiency and cost are worsened
Solution Approach 1:
The patent merges driving information from multiple vehicles into a unified database. Instead of requiring one vehicle to cover all lanes, the system combines data from many vehicles, each contributing information from their respective driving paths, thereby achieving complete lane coverage efficiently
Solution Approach 2:
The lane information database serves multiple functions: it stores lane positions, lane widths, road network connections, and can be used for navigation, route planning, and various value-added services. This multi-functional database reduces the need for separate data collection efforts
2Measurement precision
If vehicles equipped with high-cost equipment are used to collect lane information, then measurement precision is improved, but device complexity and cost are worsened
Solution Approach 1:
The system uses copies of lane information from multiple vehicles rather than requiring one vehicle to directly measure all lanes. Each vehicle captures lane information as a copy from its perspective, and these copies are integrated to form complete lane data, reducing the need for expensive comprehensive measurement equipment
Solution Approach 2:
The patent replaces the mechanical approach of physically driving vehicles on every lane with an information processing system that collects, accumulates, and compiles data from multiple sources. This substitution of mechanical data collection with informational compilation reduces equipment requirements
3Reliability
If lane information is established by driving on all roads nationally, then lane information completeness is improved, but time consumption and cost are worsened
Solution Approach 1:
The system performs preliminary data collection during normal vehicle operations. As vehicles drive on various roads performing their regular functions, their driving information is collected and stored in advance, so that lane information is already prepared when needed for navigation or other applications
Solution Approach 2:
The data collection process continues continuously as vehicles operate on the roads. Instead of dedicated survey trips, the system continuously accumulates driving information from vehicles during their normal operations, making the data collection process ongoing and efficient
Data Source
AI summary
An apparatus for establishing lane information using driving information of a vehicle is provided. The apparatus comprises a map information storing unit storing digital map information and a driving information collecting unit collecting driving information from a plurality of vehicles. An accumulating and compiling statistics unit accumulates the driving information of each vehicle collected by the driving collecting unit and then compiles statistics on the accumulated driving information. A controlling unit generates lane information based on a statistics result of the accumulating and compiling statistics unit and the digital map information. A lane information database stores the lane information generated by the controlling unit.
