The invention discloses a trailer head deflection angle measuring method and system, and the method comprises the steps: 1, employing a short-distance laser range finder as a distance measuring device, and enabling the laser range finder to be installed on a carriage or a trailer base; 2, when the steering wheel of the automobile is 0 degree, 0-degree position calibration is triggered, and the current distance value d0 measured by the laser range finder is recorded; 3, the deflection angle is calculated, when the vehicle head turns to the long-distance side, the measured value of the laser range finder is d, and the calculation formula of the deflection angle of the vehicle head is as follows: # imgabs0 #; when the vehicle head turns to one side of a close distance, the measured value of the laser range finder is d, and the calculation formula of the deflection angle of the vehicle head is # imgabs1 #; and 4, after the deflection angle is calculated in the step 3, smooth filtering processing is carried out, and anti-shake processing is carried out on slight shake of the measured value.
本发明公开一种拖挂车车头偏转角度的测量方法及系统,1、测距装置使用近距离激光测距仪,激光测距仪安装在车箱上或安装在拖挂车底座上;2、在汽车方向盘为0度时,触发0度位置校准,记录下当前的激光测距仪测得的距离值d0;3、计算偏转角度:当车头转向远距离一侧时,激光测距仪测量值为d,车头偏转角计算公式如下:#imgabs0#;当车头转向近距离一侧时,激光测距仪测量值为d,车头偏转角计算公式如下:#imgabs1#;4、步骤3中计算出偏转角后,进行平滑滤波处理,对测量值的轻微抖动进行防抖处理。
