Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous vehicle technologies face challenges in recognizing peripheral obstacles and accurately estimating the arrival distance of communication signals, particularly in varying environments like downtown areas, leading to increased accident risks due to signal congestion and interference.
Innovation Solution
An electronic device for vehicles that processes sensor data to estimate the arrival distance of V2X communication signals, calculates a time to prepare for potential dangers based on vehicle speed, and generates control signals to adjust speed accordingly, reducing false alarms and enhancing safety by classifying danger levels and displaying them to the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2X communication is used to supplement sensor functions, then the ability to recognize peripheral obstacles is improved, but the reliability deteriorates when communication signal arrival distance varies abruptly in downtown areas with obstacles
Solution Approach 1:
The patent introduces a mediator system that combines V2X communication data with sensor data (lidar, radar, camera) to cross-validate and correct communication signal arrival distance estimates. When obstacles block direct line-of-sight, the sensor data serves as an intermediary to verify or adjust the V2X signal interpretation, preventing false distance estimates while maintaining the benefits of V2X communication for obstacle recognition.
2Adaptability or versatility
If V2X communication signals are used in downtown areas with many obstacles, then information exchange capability is improved, but the reliability deteriorates due to signal congestion and interference
Solution Approach 1:
The patent implements feedback mechanisms where the vehicle continuously monitors communication signal quality and sensor detection results, then adjusts its interpretation of V2X messages accordingly. When sensor data indicates obstacles that should block signals, the system feeds this information back to filter or discount corresponding V2X communications, maintaining adaptability for information exchange while ensuring reliability through continuous verification.
3Productivity
If the vehicle travels at high speed, then productivity is improved, but the time to prepare for danger deteriorates when communication signal arrival distance is underestimated
Solution Approach 1:
The patent applies preliminary action by using V2X communication to provide advance warning of potential hazards before they are detected by onboard sensors. The system processes communication signals about distant obstacles, pedestrians, or traffic conditions and prepares danger assessment in advance, giving the vehicle more time to react even at high speeds. This preliminary information allows the system to begin safety preparations earlier than traditional sensor-only systems could achieve.
