    • In order to consider an optimum control method and an optimum mounting method needed, a UWB having a communication function and a radar function are used. For an obstacle vehicle in front, the distance between two cars is measured using the radar function, and according to this distance, a hazard warning is issued to a driver or a pre-crash operation is carried out. Moreover, by informing its own position to each other between vehicles using the communication function, the distance to a vehicle near to the own vehicle is measured regardless of clutter, and according to this distance, a hazard warning is issued to a driver or a pre-crash operation is carried out. Moreover, the operating frequency and transmission power of a radar are changed based on its own location information, thereby reducing influence to and from other wireless system.
    • 为了考虑最佳控制方法和所需的最佳安装方法,使用具有通信功能和雷达功能的UWB。 对于前方的障碍车辆,使用雷达功能测量两辆车之间的距离,并且根据该距离,对驾驶员发出危险警告或进行预碰撞操作。 此外,通过使用通信功能在车辆之间通知彼此的位置,无论杂波如何,都测量到本车辆附近的车辆的距离,并且根据该距离,向驾驶员或预先发出危险警告 - 执行碰撞操作。 此外,雷达的工作频率和发射功率根据其自己的位置信息而改变,从而减少对其他无线系统的影响。
