The invention discloses a rail transit vehicle and a bogie attitude detection method thereof, when the rail vehicle is static, zero position calibration is carried out on a straight road, and a calibrated bogie and vehicle body transverse relative displacement initial measurement value A0 and/or a calibrated bogie and vehicle body vertical relative displacement initial measurement value B0 are/is obtained; two horizontal range finders are installed on the side face of the vehicle body, two vertical range finders are installed on the bottom face of the vehicle body, and the horizontal deflection angle alpha and the transverse displacement A of the bogie are obtained according to the distance measured by the two horizontal range finders and the initial measurement value A0 of the transverse relative displacement of the vehicle body; and the vertical deflection angle beta and the vertical displacement B of the bogie are obtained by using the distance measured by the two vertical range finders and the initial measurement value B0 of the vertical relative displacement of the vehicle body. According to the invention, the bogie attitude detection difficulty is reduced, and the accurate detection of the bogie attitude is realized on the premise of as few detection points and as few sensor types as possible.

    本发明公开了一种轨道交通车辆及其转向架姿态检测方法,当轨道车辆静止时,在平直道上进行零位标定,获得标定后转向架与车体横向相对位移初始测量值A0,和/或标定后转向架与车体垂向相对位移初始测量值B0;在车体侧面安装两个水平测距仪,在车体底面安装两个垂直测距仪,利用两个水平测距仪测得的距离以及车体横向相对位移初始测量值A0,获得转向架的水平偏转角α和横向位移A;利用两个垂直测距仪测得的距离以及车体垂向相对位移初始测量值B0,获得转向架的垂直偏转角β和垂向位移B。本发明降低了转向架姿态检测难度,在尽量少的检测点和尽量少的传感器种类前提下,实现了转向架姿态的准确检测。
