Vehicle Driving Assistance for Lane-Level Path Recommendation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving assistance systems cannot determine a lane-level location of a vehicle using GPS location information and are limited in displaying a lane-level path, as they can only provide road-level precision, which restricts their ability to offer detailed navigation and communication efficiency.
Innovation Solution
A driving assistance apparatus that performs V2X communication to receive data from other vehicles, utilizing GPS location information and surrounding image information to determine a lane-level location and set a lane-level recommended path, thereby enhancing navigation precision and reducing communication load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS location information is used to determine vehicle location, then the system can determine road-level location, but it cannot determine lane-level location
Solution Approach 1:
The patent introduces other vehicles as intermediaries that transmit their precise location information and surrounding image data. These other vehicles act as mobile sensors that can determine lane-level locations, and they share this information with the host vehicle through V2V communication, thereby indirectly providing lane-level location capability without requiring the host vehicle to have direct lane-level sensing capability.
Solution Approach 2:
The system copies location and environmental information from other vehicles that have captured it. Instead of each vehicle independently determining lane-level location, the host vehicle receives and utilizes location data, image information, and lane determination results from other vehicles, effectively copying their sensing and processing capabilities.
2Loss of information
If data from all received vehicles is processed, then more location information is available, but communication load increases
Solution Approach 1:
The system extracts and processes only the relevant data from received V2V messages. Instead of processing all incoming data from all vehicles, it selectively processes data from vehicles located on the set path, extracting only the necessary location information, image data, and lane determination results while discarding irrelevant information from other vehicles.
Solution Approach 2:
The system applies different processing quality to different data sources based on their relevance. Data from vehicles on the set path receives full processing attention for lane-level determination, while data from other vehicles is either discarded or processed at a lower level, optimizing computational resources for the most critical information.

AI summary
Disclosed is a driving assistance apparatus for a vehicle, including: a communication apparatus configured to perform V2X communication with an external device outside of the vehicle; and a processor which is configured to: acquire information about a set path for the vehicle; receive V2V data from one or more other vehicles through the communication apparatus; based on the information about the set path and the one or more V2V data, select, from among the one or more V2V data, data of interest which is V2V data transmitted by a vehicle of interest which is a other vehicle located on the set path; and set a recommended path for the vehicle based on the data of interest.
