本发明属于汽车驾驶主动预警技术领域,公开了一种高速公路自车周围车流量实时监测预警装置及方法;所述装置包括:4个毫米波雷达、车速传感器、车载CAN总线、CAN总线转换器、微处理器和闪光蜂鸣器;每个毫米波雷达的信号输出端、车速传感器的信号输出端分别与车载CAN总线电连接,车载CAN总线还与CAN总线转换器的信号输入端电连接,CAN总线转换器的信号输出端与微处理器的I/O输入端连接,微处理器的I/O输出端与闪光蜂鸣器的控制端电连接;能够检测自车所处交通环境中的车流量,判断是否存在车速较高且车流量超出阈值的危险状况,以警示驾驶员采取换道或加速等操作时要谨慎,降低驾驶员操作错误的可能性。

    The invention belongs to the technical field of automobile driving active early-warning and discloses anearly-warning device and method for nearby vehicle flow real-time monitoring for a vehicle on the highway. The device includes four millimeter wave radars, a vehicle speed sensor, a vehicle-mounted CAN bus, a CAN bus converter, a microprocessor and a flash buzzer; the signal output end of each millimeter wave radar and the signal output end of the vehicle speed sensor are electrically connected with the vehicle-mounted CAN bus respectively, the vehicle-mounted CAN bus is also electrically connected with the signal input end of the CAN bus converter, the signal output end of the CAN bus converter is connected with an I/O input end of the microprocessor, and the I/O output end of the microprocessor is electrically connected with a control end of the flash buzzer. The device can detect the vehicle flow in an traffic environment in which the vehicle is, determines whether such danger conditions that the vehicle speed is relatively high and the vehicle flow exceeds a threshold value exist or not so as to alert a driver to be careful to change tracks or increase speeds, and reduces the possibility of operation errors of the driver.
