摘　　要：提出基于QNX的车机蓝牙无线监控系统方案,以手机端和车载端的蓝牙SPP协议为基础,设计CAN-USB模块作为车机通信枢纽,对两端蓝牙无线指令数据进行对等收发和处理;采用CAN总线实时采集和配置车辆ECU的各项性能参数。实验表明,该方案不仅能用手机对车辆运行状态进行实时监测和控制,而且有效提升了车辆操控的互联性和智能性。This paper presents vehicle and phone wireless monitoring system of Bluetooth technology based on QNX. With the mobile terminal and car-side Bluetooth SPP protocol, CAN-USB module was designed as a communications hub for both terminals, which is used to peer transceivers. Otherwise, CAN line was used to collect and eonfigure the vehicle ECU performance parameters. Experiments show that： the program can not only monitor and control the running state of the vehicle by the phone, but also can effectively enhance the vehicle interconneetivity and intelligent.
