Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle control systems face challenges with large amounts of V2X data, leading to memory shortages, delayed critical information, increased communication costs, and excessive bandwidth consumption, which can affect real-time operation and reliability.
Innovation Solution
A vehicle control device and method that selectively receives and processes V2X information based on a region of interest determined by the vehicle's expected driving route, using a communication unit to request and receive pertinent data, thereby reducing unnecessary data reception and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle receives all V2X information without selection, then complete information is available for control decisions, but memory capacity is exceeded and processing becomes inefficient
Solution Approach 1:
The patent segments V2X information reception by defining a region of interest based on the expected driving route. The control unit divides the overall V2X data stream into relevant portions (within the region of interest) and irrelevant portions (outside the region), selectively receiving only the relevant data. This segmentation resolves the contradiction by maintaining reliability for critical decisions while reducing memory consumption through selective data intake.
Solution Approach 2:
The control unit extracts and extracts only the necessary V2X information that falls within the predetermined region of interest. By taking out only the relevant position data and V2X information associated with the expected driving route, the system avoids storing unnecessary data, thus resolving the memory capacity issue while maintaining the reliability needed for safe autonomous driving decisions.
2Reliability
If the vehicle receives all V2X information, then no critical information is missed, but communication bandwidth is excessively consumed
Solution Approach 1:
The system extracts only the essential V2X information within the region of interest, excluding redundant data. This extraction approach maintains accuracy for autonomous driving decisions by ensuring all relevant critical information is captured, while simultaneously reducing communication bandwidth consumption by filtering out unnecessary data transmissions.
3Reliability
If the vehicle processes all received V2X data, then comprehensive analysis is achieved, but processing time increases and real-time operation is affected
Solution Approach 1:
The patent applies segmentation by pre-defining the region of interest based on the expected driving route before data reception. This allows the control unit to segment the data processing task, analyzing only the relevant V2X information within the region rather than processing all incoming data. This resolves the contradiction by maintaining comprehensive analysis of critical data while reducing processing time to meet real-time operational requirements.
Solution Approach 2:
The system performs preliminary action by determining the expected driving route and establishing the region of interest in advance of receiving V2X information. This pre-processing step enables the control unit to quickly filter and analyze only relevant data during real-time operation, maintaining thorough analysis of necessary information while avoiding the time penalty of processing unrelated data.
4Reliability
If the vehicle requests and receives V2X information from all communication-enabled devices, then all possible data sources are utilized, but communication costs increase
Solution Approach 1:
The control unit extracts and requests V2X information only from devices whose transmitted data falls within the predetermined region of interest. This selective extraction approach ensures availability of all relevant V2X information from appropriate sources while reducing communication costs by avoiding requests for and reception of unnecessary data from devices outside the region of interest.

AI summary
A vehicle control device for a vehicle includes: a communication unit configured to receive vehicle-to-everything (V2X) information, the V2X information including position data; and a control unit configured to generate a control signal associated with driving of the vehicle based on the V2X information. The control unit generates the control signal associated with driving of the vehicle by: determining an expected driving route of the vehicle; based on the determination of the expected driving route of the vehicle, determining a region of interest; and based on the determination of the region of interest, selectively receiving first V2X information associated with the region of interest by: transmitting, through the communication unit, a request for transmission of the first V2X information associated with the region of interest to communication-enabled devices; and receiving, through the communication unit, the first V2X information transmitted by the communication-enabled devices.
