Vehicle Wireless Communication Source Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current car-2-car communication methods fail to provide targeted and immediate assistance to drivers in complex traffic situations, particularly in understanding hazardous locations and overtaking maneuvers, as they do not specifically identify the source vehicle or provide relevant information to the driver.
Innovation Solution
A method where a first vehicle identifies a second vehicle in front of it using sensors or GPS, receives and processes driving information, and outputs it to the driver via output means, including optical, acoustic, or haptic signals, to assist in navigating traffic situations and overtaking processes, utilizing a wireless decentralized ad hoc network like WLAN for communication.

Engineering Contradiction Analysis
1Speed
If wireless car-2-car communication is used to transmit information between vehicles, then information about hazardous locations can be transmitted quickly, but the receiving vehicle cannot identify the source vehicle or determine whether the information is relevant to its specific situation
Solution Approach 1:
The patent uses registration plate recognition technology to create a visual copy/image of the source vehicle's identification. The receiving vehicle captures an image of the transmitting vehicle's registration plate, processes it to extract identification information, and uses this to attribute the transmitted hazard information to a specific source vehicle. This allows the receiving vehicle to know exactly which vehicle is providing the warning information.
Solution Approach 2:
The patent introduces an intermediary processing system that bridges the gap between wireless communication and driver understanding. This intermediary system includes: (1) a registration plate recognition module that identifies the source vehicle, (2) a relevance determination module that assesses whether the hazard information applies to the receiving vehicle's situation, and (3) a selective output module that presents only relevant information to the driver. This intermediary layer preserves the speed of wireless transmission while adding crucial contextual information.
2Loss of information
If all received wireless information is processed and displayed to the driver, then complete information is provided, but the driver is overwhelmed with irrelevant information in complex traffic situations
Solution Approach 1:
The patent applies local quality by making different parts of the information processing system perform different functions. The registration plate recognition module handles source identification, the relevance determination module filters information based on the receiving vehicle's specific context (such as its position, speed, and surrounding traffic conditions), and the output module presents only the most relevant information to the driver. This selective processing ensures that the driver receives complete but not overwhelming information.
Solution Approach 2:
The patent uses partial action by selectively processing and displaying only the portion of received information that is relevant to the receiving vehicle's current situation. Rather than displaying all received hazard information, the system evaluates each piece of information against the receiving vehicle's context and displays only those that apply. This partial processing approach prevents information overload while maintaining completeness of relevant information.
3Measurement precision
If registration plate recognition is used to identify the second vehicle, then unambiguous identification of information source is achieved, but additional processing time and computational resources are required
Solution Approach 1:
The patent applies preliminary action by having vehicles continuously capture and pre-process images of surrounding vehicles' registration plates even before wireless communication occurs. When a transmitting vehicle sends hazard information, the receiving vehicle already has pre-processed identification data ready, eliminating the need for real-time image processing during the critical response moment. This preliminary preparation maintains high identification precision while minimizing additional processing time.
