4地点检测与曲线检测确定列车在线路上的运行位置的地点检测,主要是防止撞车及进行运转控制。而即使在车体倾摆系统中,为实现正确的车体倾摆,也必须在车辆上经常地、高精度地识别车辆本身位置与曲线的相对位置。4.1国外技术动向4.1.1利用搭载在头车的摇头速率陀螺仪检测曲线欧 4 Location detection and curve detection Determine the location of the train running on the line location detection, mainly to prevent collision and operation control. Even in the vehicle body tilting system, in order to realize the correct vehicle body tilting, the relative position of the vehicle itself and the curve must be constantly recognized with high accuracy in the vehicle. 4.1 Foreign technical trends 4.1.1 The use of head shaking in the head rate gyroscope curve detection Europe
