摘　　要：为了提高汽车的驾驶体验,适应汽车节能与环保的发展需求,对各类传统车载终端进行功能整合与扩展,设计一款涵盖导航娱乐、上网、蓝牙通话、行驶记录、远程诊断与控制的新型车载终端。同时,通过硬件上的器件选型与电路设计、软件上的工作模式管理与任务处理机制设计,提出了具有3种工作模式的功耗管理方案,很大程度降低了系统运行功耗,休眠模式功耗小于0.1 W。装车试验表明,设计的车载终端不仅提高了汽车的增值服务,还大大延长了汽车电平的使用寿命。In order to improve the driving experience of the car and meet the development need of the energy saving and environmental protection, a new vehicle terminal is designed with the functions of navigation, entertainment, Internet,bluetooth phone, driving record, remote diagnosis and control. At the same time,devices select methods,hardware circuit design methods, working modes management and tasks processing mechanism are used to reduce the power consumption of system. The power consumption in sleep mode is less than 0.1 W. As a result, the vehicle terminal improves the service of the car and the car battery can work more longer.
