Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle environment data transmission methods face challenges with continuous data collection and transmission, particularly due to limited storage capacity and sporadic availability of high-bandwidth networks, leading to inefficient data management and potential loss of critical information.
Innovation Solution
A control device and method that dynamically adjust data transmission modes between vehicles and servers based on three modes: monitoring, urgency, and efficiency, allowing for continuous data monitoring, increased data transmission in urgent situations, and selective data storage and transmission using multiple standards, optimizing data handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If continuous monitoring and transmission of vehicle environment data is performed, then comprehensive data coverage is achieved, but storage capacity is exceeded and transmission efficiency decreases
Solution Approach 1:
The patent applies local quality by differentiating data transmission strategies based on urgency levels. Critical data (high urgency) is transmitted immediately with high priority, while non-critical data (low urgency) is transmitted when resources are available. This selective approach ensures comprehensive data coverage for critical events while managing storage capacity constraints by not treating all data equally.
Solution Approach 2:
The system changes transmission parameters dynamically based on urgency levels and resource availability. Transmission priority, frequency, and data volume are adjusted as parameters according to the urgency classification of different data types, allowing the system to maintain comprehensive monitoring coverage while adapting to varying storage and bandwidth constraints.
2Loss of information
If increased amount of data is transmitted in urgency mode, then critical information is preserved, but storage capacity is consumed faster
Solution Approach 1:
The patent implements local quality by assigning different transmission priorities to different data based on their urgency classification. Critical information receives high-priority transmission ensuring it is preserved and sent to the server promptly, while non-critical data receives lower priority. This differentiated approach preserves critical information without unnecessarily consuming storage capacity for all data types equally.
Solution Approach 2:
The system uses feedback mechanisms where the server communicates back to the vehicle about data reception status and resource availability. This feedback allows the vehicle to adjust its data retention and transmission strategies, preserving critical information while managing storage capacity consumption based on actual server needs and current resource states.
3Productivity
If data is stored selectively and transmitted based on multiple standards, then transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing data into distinct urgency categories (high, medium, low) and applying different transmission strategies to each segment. This segmentation simplifies the control logic compared to treating all data uniformly, as each segment has predefined transmission rules. The system achieves improved transmission efficiency by transmitting high-urgency data immediately while scheduling low-urgency data for later transmission when resources are available.
Solution Approach 2:
The system implements dynamic transmission strategies that adapt to current resource conditions and data characteristics. Transmission parameters such as priority, timing, and protocol selection are dynamically adjusted based on urgency levels and available bandwidth, improving transmission efficiency while the dynamic nature allows the system to handle complexity through adaptive rather than static rules.
4Adaptability or versatility
If multiple data transmission standards are used, then transmission flexibility is improved, but ease of operation decreases
Solution Approach 1:
The patent uses segmentation to associate different transmission standards with specific data urgency segments. Each urgency level has predefined transmission protocol requirements, which simplifies operation within each segment. The system maintains transmission flexibility by selecting appropriate standards for different data types while reducing operational complexity through standardized rules for each segment rather than requiring complex real-time decisions.
Solution Approach 2:
The system implements self-service by automatically selecting and applying the appropriate transmission standard based on the data's urgency classification and current resource conditions. This automated standard selection improves transmission flexibility to handle various data types appropriately while maintaining ease of operation by eliminating the need for manual intervention in standard selection, allowing the system to operate itself according to predefined rules.

AI summary
A technology of controlling vehicle environment data transmission between a vehicle and a server is configured to receive mode information determining a mode among a monitoring mode, an urgency mode, or an efficiency mode. When determined to be operated in the monitoring mode, a control command for instructing the vehicle to perform a continuous monitoring or a regular monitoring of an environment of the vehicle is generated. When determined to be operated in the urgency mode, a control command for instructing the vehicle to transmit an increased amount of the vehicle environment data from the vehicle to the server is generated. When determined to be operated in the efficiency mode, a control command for instructing the vehicle to store the vehicle environment data and to selectively transmit the vehicle environment data based on at least two different data transmission standards is generated.
