Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary HD map formats are used by different HD map providers, then each provider can maintain its own quality-of-service requirements and data structure, but autonomous vehicles cannot utilize HD map information from non-subscribed providers, resulting in limited coverage and interoperability issues
Solution Approach 1:
The patent introduces a universal HD map data structure as an intermediary format that enables data exchange between proprietary HD map providers and autonomous vehicles. This universal structure acts as a mediator that preserves the quality-of-service requirements of proprietary formats while enabling interoperability across different providers, allowing vehicles to utilize HD map information from any subscribed or non-subscribed provider.
Solution Approach 2:
The patent creates a universal HD map data structure that serves multiple functions: it maintains compatibility with proprietary formats, enables cross-provider interoperability, and supports both subscribed and non-subscribed vehicles. This universal structure allows a single HD map data format to fulfill multiple roles across different ecosystems and providers.
2Reliability
If proprietary HD map solutions are implemented, then HD map data can be provided with specific quality-of-service guarantees, but crowdsourcing becomes difficult as communication protocols are unknown to non-subscribed autonomous vehicles
Solution Approach 1:
The universal HD map data structure serves as an intermediary that enables crowdsourcing communication between autonomous vehicles and HD map providers. Non-subscribed vehicles can contribute sensor data and map updates using this universal format, even without knowledge of proprietary communication protocols, thereby facilitating crowdsourcing while maintaining quality-of-service guarantees.
3Reliability
If multiple proprietary HD map formats are used by different providers, then each provider can optimize for its specific requirements, but the overall HD map coverage is limited as different providers cover different areas
Solution Approach 1:
The universal HD map data structure enables HD map coverage expansion by allowing autonomous vehicles to access and integrate map data from multiple proprietary providers. This universal format acts as a common denominator that consolidates coverage areas from different providers, creating a more comprehensive global HD map coverage while preserving each provider's optimized data structure for their specific regions.

AI summary
Technologies for managing interoperable high definition (HD) maps for autonomous vehicles includes a HD map server to distribute interoperable HD map tiles to various autonomous vehicles, each of which may be configured to utilize proprietary HD map tiles of different propriety formats. As such, each of the autonomous vehicles is configured to translate the interoperable HD map tile to the proprietary format used by that particular vehicle. Additionally, each autonomous vehicle may submit crowd-sourced sensor data to the interoperable HD map server using a universal data set by converting the sensor data to a universal data structure.
