Vehicle Data Prioritization for Service-Critical Information Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing log collection systems prioritize information transmission based on potential attacks, leading to deterioration in the quality of services or functions provided when communication is disrupted, as they fail to transmit essential information necessary for service provision.
Innovation Solution
An information collection device that acquires and prioritizes information based on the services or functions used by the driver, selecting and transmitting only the necessary information to the server device, thereby preventing service quality deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all collected information is transmitted to the server device, then the completeness of information is improved, but communication bandwidth consumption increases and congestion occurs
Solution Approach 1:
The patent extracts and transmits only the necessary information for service provision from the collected information set. The determination unit identifies and selects only those information items required for the driver's services, excluding redundant data, thereby reducing communication bandwidth consumption while maintaining service quality.
Solution Approach 2:
The patent applies different selection criteria to different types of information based on their relevance to specific services. Each information item is evaluated individually for its necessity to the driver's services, allowing selective transmission of high-value information while filtering out low-value data.
2Reliability
If information is prioritized based on attack detection, then security analysis capability is improved, but service provision quality deteriorates
Solution Approach 1:
The patent inverts the priority determination logic: instead of prioritizing information based on potential attacks (server-side perspective), it prioritizes information based on service provision needs (client-side perspective). The determination unit in the information collection device identifies necessary information before transmission, ensuring service quality is maintained.
Solution Approach 2:
The information collection device performs self-service by autonomously determining which information is necessary for service provision without requiring server-side attack analysis instructions. This enables the system to maintain service quality independently of security analysis priorities.
3Loss of information
If storage capacity is increased to store all information during communication disruption, then information availability is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts only the necessary information items for service provision before storing them during communication disruptions. By pre-identifying and selecting only essential information, the storage capacity requirement is significantly reduced while maintaining information availability for critical services.
Solution Approach 2:
The determination unit performs preliminary identification of necessary information before communication disruption occurs. This advance selection ensures that only essential information is stored in limited capacity memory, enabling the system to maintain service provision quality even during extended communication outages.

AI summary
An acquisition unit acquires pieces of information including information related to a vehicle, information related to the environment inside and outside the vehicle, and information related to a driver on board the vehicle. A determination unit determines priorities of the pieces of information acquired by the acquisition unit on the basis of a service or the like used by the driver among services or the likes provided using information accumulated in a server device. A selection unit selects a piece of information to be transmitted to the server device from among the pieces of information acquired by the acquisition unit on the basis of the priorities determined by the determination unit. A communication unit transmits the piece of information selected by the selection unit to the server device.
