摘　　要：介绍了RDS功能在车载音响系统中的应用与实现,并设计低功耗硬件电路以适应车载供电的要求。RDS功能采用SI473X嵌入式芯片实现,通过软件编程实现了带RDS的数字调频立体收音功能,为车载音响系统提供调频接收和RDS信息服务。通过平台测试,证明是一种廉价可行的解决方案。The application and implementation of RDS function in vehicle-mounted audio system are introduced. A low- power hardware circuit was designed to meet automotive power supply. The RDS function was implemented by DSP embedded Module SI473X. The software of RDS function and digital FM stereo radio is introduced. This design provided FM radio and RDS information services for the vehicle-mounted audio systerm It is a cheap and viable solution through a hardware platform test.
