Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles without imaging devices or radar sensors cannot utilize advanced driving assistance systems due to the high cost and limited availability of these technologies, restricting their access to features like lane change assistance and collision prevention.
Innovation Solution
A vehicle control system utilizing V2X communication to receive surrounding information, including lane information, from other vehicles or infrastructure, convert this information into a format relevant to the subject vehicle, and perform control operations such as lane keeping assistance and lane change control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If imaging devices or radar sensors are installed in vehicles to enable driving assistance systems, then driving safety and control capabilities are improved, but vehicle cost increases and accessibility decreases
Solution Approach 1:
The patent introduces V2X communication as an intermediary mechanism that allows vehicles without imaging devices or radar sensors to receive surrounding information from other vehicles. This mediator enables driving assistance functionality through information exchange rather than direct sensing, resolving the contradiction between safety and cost by providing an alternative technical path.
Solution Approach 2:
The patent enables vehicles without expensive sensors to copy the surrounding information capabilities of vehicles equipped with imaging devices and radar sensors by receiving data through V2X communication. This copying approach allows lower-cost vehicles to access the same driving assistance functionality without physically installing the expensive sensing hardware.
2Adaptability or versatility
If V2X communication is used to receive surrounding information from other vehicles, then driving assistance capabilities become accessible to lower-cost vehicles, but information accuracy and reliability may be affected
Solution Approach 1:
The patent merges information from multiple sources including V2X communication data and the subject vehicle's own sensors (camera, microphone, etc.) to create a comprehensive surrounding information picture. This combination approach compensates for potential inaccuracies in V2X data by cross-validating with other information sources, thereby maintaining measurement precision while preserving system accessibility.
Solution Approach 2:
The patent implements feedback mechanisms where the subject vehicle's sensors continuously verify and correct the surrounding information received through V2X communication. This feedback loop ensures that information accuracy is maintained by comparing externally received data with locally sensed data, adjusting for discrepancies in real-time.
