Autonomous Driving Control in Restricted Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In restricted areas, such as military or security zones, the lack of map data due to security policies prevents the generation of driving plans for autonomous vehicles, making it impossible to apply existing autonomous driving methods or systems effectively.
Innovation Solution
An autonomous driving control method and system that converts the vehicle's driving mode into a restricted area autonomous driving mode, where memory access, communication, and information acquisition are restricted, by transmitting a destination and authentication key to a restricted area management server, which generates and encrypts a global path, and the vehicle decrypts and follows this path within the restricted area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing autonomous driving methods are applied in restricted areas, then autonomous driving functionality is maintained, but map data cannot be generated due to security policies
Solution Approach 1:
The patent segments the autonomous driving system into multiple components: a server that generates and encrypts map data, a vehicle terminal that receives and decrypts the data, and a restricted area management system. This segmentation allows map data to be generated externally and securely transmitted to the vehicle without requiring the vehicle to access restricted area databases directly, thus resolving the contradiction between maintaining autonomous driving capability and adhering to security policies.
Solution Approach 2:
The patent introduces an intermediary encryption/decryption mechanism between the map data generation system and the vehicle system. The server encrypts map data before transmission, and the vehicle terminal decrypts it for local use. This intermediary cryptographic layer enables the vehicle to access and use map data in restricted areas without directly accessing the restricted database, thereby maintaining autonomous driving functionality while complying with security restrictions.
2Ease of operation
If map data is accessed in restricted areas, then route generation is enabled, but security policies are violated
Solution Approach 1:
The patent implements preliminary action by having the server generate and encrypt map data before the vehicle enters the restricted area. The encrypted data is transmitted to the vehicle in advance, allowing route generation to occur using pre-acquired data rather than real-time access to restricted databases. This approach enables route generation functionality while preventing security violations by eliminating the need for the vehicle to access restricted area databases during operation.
Solution Approach 2:
The patent creates a copy of the map data on the server side, encrypts it, and transmits it to the vehicle terminal. The vehicle receives and stores a decrypted copy of the map data locally, which can then be used for route generation without accessing the original restricted database. This copying mechanism enables route generation while maintaining security by separating the vehicle's data access from the restricted database.
3Reliability
If communication is restricted in the vehicle, then information security is improved, but data transmission capability is reduced
Solution Approach 1:
The patent implements dynamic communication control where the vehicle terminal can switch between different communication modes based on location. When entering a restricted area, the system automatically restricts communication channels and activates local decrypted map data for route generation. When outside restricted areas, normal communication capabilities are restored. This dynamic adjustment maintains information security within restricted zones while preserving data transmission capability when security concerns are not applicable.

AI summary
An autonomous driving control method for a vehicle includes: converting a driving mode into a restricted area autonomous driving mode in which memory access, communication with a network, and information acquisition are restricted in a restricted area; transmitting a destination in the restricted area and an authentication key to a server by an autonomous driving system; checking validity of the authentication key, and generating a global path to the destination in the restricted area when the authentication key is valid, by the server; encrypting the global path and transmitting it with a decryption key to the autonomous driving system by the server; and restoring the encrypted global path using the decryption key by the autonomous driving system.
