ADAS Map Generation Using Vehicle Position Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating Advanced Driver Assistance System (ADAS) maps are expensive and time-consuming, requiring manual surveying and updates, while vehicle position sensors like GPS and gyro sensors are not utilized effectively for map generation.
Innovation Solution
A system and method that collect and analyze data from vehicle position sensors, such as GPS and gyro sensors, to automatically generate ADAS maps, using a data analysis/map generation controller connected to a telematics center, which processes data in real-time to create 3D maps, reducing construction costs and enabling rapid updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual surveying and semiautomatic map construction methods are used, then map accuracy and reliability are improved, but construction cost and time consumption increase significantly
Solution Approach 1:
The patent replaces manual surveying equipment and semiautomatic processing systems with an automated system that uses vehicle-mounted position sensors (GPS, gyro sensors) to collect data and automatically generates ADAS maps through computer processing, eliminating the need for manual road surveying and significantly reducing construction time while maintaining map accuracy
Solution Approach 2:
The patent creates a virtual copy of the physical road environment by collecting position sensor data from vehicles and generating a digital ADAS map that replicates road geometry, curvature, and slope information, enabling automated map construction without physical surveying
2Loss of information
If manual surveying methods are used, then comprehensive road data can be collected, but construction cost increases significantly
Solution Approach 1:
The patent makes vehicle position sensors serve multiple functions: they are used for vehicle location guidance and simultaneously for collecting road geometry data to generate ADAS maps, eliminating the need for dedicated surveying equipment and reducing construction costs while maintaining data completeness
Solution Approach 2:
The patent enables the vehicle's own position sensor system to serve the dual purpose of navigation and map generation, where the vehicle effectively surveys the road environment during normal operation without requiring external surveying resources
3Reliability
If traditional map updating processes are used, then map accuracy is maintained, but update frequency and rapidness decrease
Solution Approach 1:
The patent implements continuous map updating by continuously collecting position sensor data from vehicles as they travel, allowing the ADAS map to be updated in real-time or near-real-time while maintaining accuracy, rather than relying on periodic manual surveying updates

AI summary
A method and a system for generating a map using data of a position sensor of a vehicle are provided which are used to generate a map by collecting data of a position sensor disposed within a vehicle. The method includes collecting, by a controller, data from the position sensor disposed within the vehicle to sense the position of the vehicle and analyzing the collected data of the position sensor. In addition, the method includes automatically generating, by the controller, the map using the analyzed data.
