Innovation Solution
A path providing device and method that includes a communication unit, interface unit, and processor to receive and process map information, sensing data from sensors, and vehicle status information, generating autonomous driving visibility information and transmitting it to servers or vehicle components, while utilizing an Event Data Recorder (EDR) to store and encrypt sensor data for fault determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle status information and autonomous driving visibility information are integrated and analyzed in real-time, then fault detection capability and safety are improved, but device complexity and data processing requirements increase
Solution Approach 1:
The patent embeds the Event Data Recorder (EDR) within the autonomous driving system architecture, creating a nested structure where the EDR is integrated into the overall vehicle control system. This allows the EDR to access and record vehicle status information from multiple sensors while remaining part of the autonomous driving infrastructure, thereby improving fault detection without proportionally increasing external device complexity
Solution Approach 2:
The EDR is designed to perform multiple functions: it records vehicle status information from various sensors, stores autonomous driving visibility information, and provides data for both safety analysis and incident reconstruction. This multi-functionality allows a single device to handle diverse data types and purposes, improving reliability while controlling the number of separate components needed
2Measurement precision
If multiple sensors and data sources are integrated for comprehensive visibility information, then measurement precision and fault detection accuracy are improved, but device complexity and information processing load increase
Solution Approach 1:
The patent segments information into distinct categories: vehicle status information from sensors, autonomous driving visibility information from the EDR, and map information from external sources. This segmentation allows each data type to be processed and stored separately according to its specific requirements, improving measurement precision through dedicated processing while managing device complexity through modular architecture
Solution Approach 2:
The EDR serves as an intermediary device that collects, stores, and manages data from multiple sensors and systems. It acts as a central repository that facilitates the integration of diverse data sources without requiring direct complex interactions between all sensor components, thereby improving data accessibility and analysis accuracy while simplifying the overall system architecture

AI summary
A path providing device configured to provide a path information to a vehicle includes: a communication unit configured to receive, from a server, map information including a plurality of layers of data, an interface unit configured to receive sensing information from one or more sensors disposed at the vehicle, a processor, and an event data recorder (EDR) configured to store vehicle status information including first sensor data sensed by a first sensor associated with an operation of the vehicle, and second sensor data sensed by a second sensor associated with surrounding information of the vehicle. The processor is configured to determine an optimal path for guiding the vehicle from an identified lane, generate autonomous driving visibility information, update the optimal path based on dynamic information and the autonomous driving visibility information, and include the vehicle status information stored in the EDR in the autonomous driving visibility information.
