Sensor-V2V Fusion for Detecting Non-Connected Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular communication systems are ineffective in detecting vehicles without vehicle-to-vehicle (V2V) capability, as they rely on V2V communication to provide accurate position information and safety warnings, which not all vehicles possess.
Innovation Solution
An electronic control unit in an ego vehicle is configured to obtain sensor data from on-board sensors, determine if a target vehicle lacks V2V capability by comparing sensor data with V2V system output, and transmit fusion data representing the target vehicle's position, direction, and speed to a traffic information collecting center for accurate detection and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If V2V communication is used for vehicle detection, then detection accuracy for equipped vehicles is improved, but detection capability for non-V2V vehicles deteriorates
Solution Approach 1:
The patent introduces sensor data as an intermediary detection mechanism. When V2V communication fails to detect a vehicle (indicating the target lacks V2V capability), the system activates sensor-based detection to capture and process visual or physical data about the non-V2V vehicle, thereby maintaining detection accuracy across all vehicle types regardless of their communication capabilities
Solution Approach 2:
The system implements a multi-functional detection approach that combines both V2V communication and sensor-based detection methods. This universal detection system can adaptively switch between or combine both methods depending on the target vehicle's capabilities, ensuring comprehensive detection coverage for both V2V-equipped and non-V2V vehicles
2Productivity
If only V2V communication is used for vehicle detection, then communication efficiency is improved, but detection coverage deteriorates
Solution Approach 1:
The system employs sensor-based detection as a supplementary partial action that activates specifically when V2V communication detection is insufficient or fails. This partial action ensures comprehensive detection coverage by capturing non-V2V vehicles that would otherwise be missed, while maintaining the efficiency of V2V communication for equipped vehicles

The method comprises obtaining sensor data from at least one on-board sensor of an ego vehicle. The sensor data indicates presence of the target vehicle within sensing range of the at least one on-board sensor. The method comprises determining that the target vehicle is without V2V capability by comparing the sensor data to output data from a V2V system of the ego vehicle. The method comprises determining, based on the sensor data and on current positioning data of the ego vehicle, fusion data representing at least one of current position, current direction and current speed of the target vehicle. The method comprises wirelessly transmitting the fusion data of the target vehicle.
