Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map data update methods result in low efficiency and safety issues for autonomous driving due to full updates based on preset frequencies, leading to outdated datasets.
Innovation Solution
A vehicle control system with an autonomous driving domain and cockpit domain that dynamically updates map datasets based on region information during navigation, enabling autonomous driving functions only when up-to-date data is available for specific geographical regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If full update is performed on map data based on preset update frequency, then map data coverage is comprehensive, but data update efficiency is low
Solution Approach 1:
The patent divides the map data update process into regional segments. Instead of updating the entire map dataset, only specific geographical regions are updated based on navigation requirements. The system segments the map data into multiple regional datasets and selectively updates only those regions that the vehicle will traverse, thereby improving update efficiency and reducing time consumption.
Solution Approach 2:
The system performs preliminary actions by pre-updating map data for specific geographical regions before the vehicle reaches them. The autonomous driving domain receives region information in advance, determines which regions need updating, and completes the updates beforehand, ensuring that current map data is available when needed without waiting for full map updates.
2Reliability
If full update is performed on map data based on preset update frequency, then all regions are covered, but autonomous driving safety is compromised due to outdated data
Solution Approach 1:
The patent applies local quality by ensuring that map data for specific geographical regions has high freshness and accuracy, while other regions may have older data. The system identifies regions where the vehicle will travel and ensures those specific areas have updated map data, rather than requiring all regions to be uniformly updated. This maintains autonomous driving safety in critical areas while improving overall update efficiency.
Solution Approach 2:
The system performs preliminary updates for regions that will be visited by the vehicle, ensuring that current and accurate map data is available before the vehicle reaches those areas. This preliminary action guarantees data freshness for safety-critical regions without requiring complete full-map updates, thereby maintaining autonomous driving safety while improving update efficiency.
3Productivity
If regional map data update is performed based on navigation path, then update efficiency is improved, but system complexity increases
Solution Approach 1:
The system implements self-service by automatically determining which regional map data needs updating based on navigation path information. The autonomous driving domain receives region information, autonomously identifies regions requiring updates, and triggers update operations without requiring complex external coordination or manual intervention. This self-service mechanism improves update efficiency while keeping system complexity manageable.

AI summary
The present application relates to the field of Internet of Vehicles and the field of intelligent transportation, and provides a map data processing method and apparatus, an electronic device, a computer readable storage medium, and a computer program product. The method comprises: in the process of a vehicle travelling on the basis of a target navigation path, an automatic driving domain receives region information sent by a cockpit domain; in a case that the vehicle is travelling in a first geographic region, when it is determined, on the basis of the region information, that the vehicle allows for automatic driving in a second geographic region and when map data of the second geographic region stored in the automatic driving domain is not map data of the latest version, obtaining the map data of the latest version of the second geographic region; and starting an automatic driving function of the vehicle on the basis of the map data of the latest version of the second geographic region.
