The system integrates 4G full Netcom, Bluetooth, cloud platform and single-chip microcomputer control technology to intelligently transform household electric vehicles and realize the remote unlocking and starting of the vehicle by mobile phone APP. With STM32 microcontroller as the main control chip, 4G full Netcom and Bluetooth as the communication bridge, and Alibaba Cloud as the server, the keyless unlocking function of the vehicle is realized through relay control. On the premise of not replacing the original lock, the system ensures the availability of the weak network environment through the 4G + Bluetooth dual communication mode. After testing, the average response time of 4G remote unlocking is 1.2 s, Bluetooth is 0.5 s, and the transmission success rate exceeds 98%, providing a cost-effective solution for the intelligent upgrade of traditional electric vehicles.
