Network Device Control System for Shared Motor Vehicles

The patent introduces a server as an intermediary between the mobile device and the motor vehicle. The server receives control requests from the mobile device via WiFi/Bluetooth, processes them securely, and then executes the corresponding actions on the motor vehicle. This intermediary architecture allows convenient wireless communication while centralizing security management and reducing direct attack surfaces between user devices and vehicle controls.

The patent implements automated leasing and returning functions where the system automatically determines parking points, manages vehicle availability, and processes leasing transactions without requiring manual intervention. The motor vehicle and mobile device automatically communicate leasing status, parking location, and returning confirmation, enabling the system to serve itself and significantly improving utilization rate while maintaining operational flexibility through programmable rules.

The patent makes the parking point assignment dynamic rather than fixed. The system automatically determines parking points based on real-time factors such as vehicle location, user preferences, available spaces, and traffic conditions. This dynamic assignment allows unmanned management to function while providing users with flexible parking options and multiple possible returning locations, thereby maintaining convenience despite automation.

The patent implements a mechanism where security patches and software updates are prepared in advance on the server side. When security vulnerabilities are detected or patches are developed, they are pre-processed, validated, and staged for deployment. The motor vehicle then receives these pre-prepared security updates through the existing communication channel, allowing security to be updated in real time without requiring system restructuring that would compromise stability.
