Aiming at the problems of fragmented functions and single interaction mode of traditional vehicle-mounted terminals, an intelligent vehicle-mounted integrated service system based on the Android platform is designed and implemented. Taking “mobile terminal-hardware collaborative control” as the core, the system integrates six modules: vehicle status monitoring, Bluetooth communication, voice recognition, music playback, map navigation, and multi-interface collaborative management. The 51 single-chip microcomputer is adopted as the underlying control core, and full-duplex low-latency communication is realized through the Radio Frequency Communication (RFCOMM) protocol under Bluetooth. Baidu Speech Recognition Software Development Kit (SDK) and Amap SDK are integrated to construct a closed-loop interaction model of “voice command – function execution – visual feedback”. Tests indicate that the system meets the real-time requirements of vehicle-mounted scenarios in key indicators such as communication latency, recognition accuracy, and positioning precision. It achieves a low-cost and high-adaptability lightweight vehicle-mounted solution, providing an effective technical reference for human-computer interaction of intelligent connected vehicles.
