Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous vehicle systems lack real-time access to comprehensive traffic, navigation, and points of interest data across vast geographic areas due to limited sensor capabilities and hardware/software functionalities, particularly in vehicles with low autonomy.
Innovation Solution
A system and method where vehicles with high autonomy transmit and convert data on traffic conditions, navigation, and points of interest into formats compatible with vehicles of lower autonomy, using various sensors and communication with management servers via a wireless network, enabling real-time data access and sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vehicles with low autonomy use conventional sensors and processing systems, then device complexity is reduced, but data access capability and measurement precision deteriorate
Solution Approach 1:
The patent introduces high autonomy vehicles as intermediaries that collect, process, and relay data to low autonomy vehicles. These high autonomy vehicles act as mediators with advanced sensors (lidar, radar, cameras) that gather comprehensive traffic, navigation, and points of interest data, then convert and transmit it to vehicles with limited capabilities through communication systems.
Solution Approach 2:
The system creates data copies from high autonomy vehicles and transmits them to low autonomy vehicles. The high autonomy vehicles capture original data using advanced sensors, then generate and share replicated data versions with vehicles that lack the hardware to collect such information directly, enabling data access without requiring each vehicle to have identical sensor suites.
2Loss of information
If vehicles with low autonomy lack advanced sensors, then manufacturing cost is reduced, but real-time data access across vast geographic areas deteriorates
Solution Approach 1:
The patent merges the data collection capabilities of high autonomy vehicles with the operational needs of low autonomy vehicles. By combining the sensor-rich platforms that can gather comprehensive real-time data with the vehicles that need this information but lack the hardware, the system creates a collaborative network where information gaps are filled through inter-vehicle communication.
Solution Approach 2:
The high autonomy vehicles serve multiple functions: they act as data collectors for themselves, as data sources for other high autonomy vehicles, and as data providers for low autonomy vehicles. This multi-functional approach allows a single vehicle with advanced sensors to benefit the entire fleet, reducing the need for every vehicle to possess identical expensive sensor configurations.
3Adaptability or versatility
If vehicles with low autonomy lack data processing functionality, then device complexity is reduced, but ability to process and utilize received data deteriorates
Solution Approach 1:
The high autonomy vehicles with advanced processing capabilities serve as intermediaries that perform data processing, format conversion, and adaptation. They receive raw data from their sensors, process it through sophisticated algorithms, convert it into appropriate formats, and transmit the processed information to low autonomy vehicles that lack the hardware to perform these functions independently.
Solution Approach 2:
The patent replaces the mechanical/sensor-based data collection system with a communication-based data transmission system. Instead of requiring low autonomy vehicles to have physical sensors and processing hardware, the system substitutes direct sensing with indirect data reception through wireless communication, allowing vehicles to access information without the corresponding hardware infrastructure.

AI summary
A method for enhancing data access capabilities of vehicles is provided. The method includes obtaining, by a first vehicle having a first level of autonomy, data in a first format, receiving, from a second vehicle having a second level of autonomy, a request for the data, converting the data from a first format to a second format based on the second level of autonomy, and transmitting the data in the second format to the second vehicle. The data in the second format is compatible with the second level of autonomy. The second level of autonomy is lower than the first level of autonomy.
