The invention discloses a method for calculating a vehicle steering transmission ratio, which solves the problems of high cost and low efficiency of the existing method for acquiring the vehicle steering transmission ratio, and specifically comprises the following steps of: 1, acquiring data; 1.1, inertial navigation equipment is installed on the vehicle, an antenna of the inertial navigation equipment is arranged on a vehicle roof, and a main antenna is arranged on the right front portion of the vehicle roof; 1.2, on the flat ground without antenna signal interference, starting vehicle inertial navigation equipment, fixing the steering angle beta of a steering wheel, driving the vehicle to advance and rotate for at least one circle, and collecting real-time position information of a main antenna; step 2, calculating a steering transmission ratio; 2.1, the collected real-time position information is fitted into a circle, the radius R'of the circle is obtained, and R 'is the turning radius of the main antenna; 2.2, the axial distance d1 from the main antenna to the rear axle of the vehicle and the distance d2 from the main antenna to the axle are obtained, and the steering transmission ratio k of the vehicle when the steering angle of the steering wheel is beta is calculated.

    本发明公开了一种车辆转向传动比的计算方法,解决了现有车辆转向传动比的获取方法成本高且效率低的问题,具体包括步骤1、采集数据;1.1、向车辆安装惯性导航设备,并将惯性导航设备的天线布置在车顶,其中的主天线设置于车顶的右前方;1.2、在无天线信号干扰的平地上,启动车辆惯性导航设备,固定方向盘转角β,驾驶车辆前行,旋转至少一周,采集主天线的实时位置信息;步骤2、转向传动比的计算;2.1、将采集到的实时位置信息拟合为圆,获取其半径R′,R′即为主天线处的转弯半径;2.2、获取主天线到车辆后轴的轴向距离d1和主天线至车轴的距离d2,计算得到车辆在方向盘转角为β时的转向传动比k。
