摘　　要：针对传统车辆短距离无线操控的缺陷,提出基于μCOS-II的车载蓝牙控制方案,通过车辆内外蓝牙信号唤醒CAN总线,以实时配置相应ECU的状态参数。设计便携设备与车载终端蓝牙无线指令收发模块BT-AM,控制车辆相关属性。实验表明,该方案不仅实现了短距离内便携设备与车载终端的无线互连互控,而且有效提升了车辆设计的人性化和安全性。For the shortcomings of conventional vehicles in short-range wireless control, p,COS-II is proposed based on Bluetooth control scheme. CAN bus is waked up by the inside and outside Bluetooth signal, so the corresponding state parameter of ECU is configured in real-time. In order to control the vehicle-related attributes, the Bluetooth wireless command transceiver module BT-AM is designed, which is based on portable devices and vehicle terminals. Experiments show that the program does not only realize the wireless connectivity and control between the vehicle terminal and portable device within a short distance, but also effectively enhance the vehicle safety and humane in design.
