Vehicle Environmental Data Fusion for Trajectory Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operation systems lack comprehensive and reliable environmental data integration, leading to safety and efficiency issues, particularly in scenarios where vehicles deviate from their trajectory due to unforeseen factors like wind or traffic density, which can result in unsafe spacing or speed changes between vehicles.
Innovation Solution
A method and apparatus that combine first environmental data from vehicle sensors with second environmental data from an external server to determine accurate environmental conditions, enabling the generation of signals for manual vehicle operation or trajectory adjustments to ensure safe and efficient travel, including detection of air flows, traffic density, and road states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If environmental data is obtained only from vehicle sensors, then the system is simple and fast, but the measurement precision and reliability are insufficient
Solution Approach 1:
The patent combines environmental data from vehicle-mounted sensors with data from external servers to create a comprehensive environmental understanding system. This merging of internal and external data sources resolves the contradiction by improving measurement precision through data fusion while managing complexity through systematic integration processes.
Solution Approach 2:
The patent introduces an intermediary data processing layer that receives environmental data from both vehicle sensors and external servers, processes and validates the information, and provides unified environmental parameters to the vehicle control system. This intermediary structure enables accurate environmental assessment without directly exposing the complexity of dual data sources to the control logic.
2Reliability
If environmental data is obtained from both vehicle sensors and external servers, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where environmental data from both vehicle sensors and external servers is continuously compared, validated, and cross-checked. The system uses feedback loops to identify discrepancies, resolve conflicts between data sources, and continuously improve the reliability of environmental assessments while maintaining manageable system complexity through structured feedback processing.
3Reliability
If comprehensive environmental data integration is implemented, then safety is enhanced, but the processing time and energy consumption increase
Solution Approach 1:
The patent applies preliminary action by pre-processing and pre-validating environmental data from both vehicle sensors and external servers before critical decision-making moments. Environmental parameters are prepared, cross-checked, and ready in advance, allowing the system to enhance safety through comprehensive data integration while minimizing processing time during actual vehicle operation through pre-computed environmental assessments.
