摘　　要：提出基于QNX的智能车载远程3G诊断系统方案,采用QNX硬实时系统作为车载终端,通过CAN总线和GPS模块实时采集车辆状态信息,以实现对车辆运行状态的动态反馈;设计3G无线分层驱动模型实现车载终端与远程服务器通信,提高远程诊断的实时性和准确性;引入远程监控服务中心对车辆各项安全参数进行动态实时检测,进而提高运行安全系数。实验表明,该方案不仅能实时采集影响车辆安全运行的各项ECU参数,还可通过车辆远程服务中心实现对车辆的全天候跟踪监控。A program of remote 3G diagnosis system was proposed based on QNX. The hardware real-time system of QNX was used to the vehicle terminal, to capture status information of the vehicle by CAN and GPS module, so as to achieve dynamic feed-back to the running status. In order to complete communicates between the ear terminal and remote servers, design 3G Wireless layered driver model. As a result , improve the real-time and accuracy of the system. In order to improve the running safety fac-tor, a remote monitoring service center was introduced, so as to check the safe parameter in real-time. Experiments show that, this program can not only capture all the ECU parameter affected the running safety, but also can trace and monitor the vehicle by the remote service center all day.
