The invention discloses a control method for automatic wheel diameter calibration of a motor train unit. Aiming at the change of a wheel diameter actual value and a wheel diameter storage value in a control system caused by abrasion or other reasons of the motor train unit, a control system automatically performs wheel diameter calibration and automatically stores the wheel diameter after calibration is completed, so that manual control and manual new wheel diameter input are not needed, and the problems that wheel diameter data is distorted and cannot be automatically updated after being lostare solved. The method comprises the following steps: 1) monitoring the running state of a rail vehicle in real time according to a TCMS, and determining whether to execute automatic wheel diameter calibration or not; 2) enabling a traction control system to detect and confirm the error speed of the GPS, and to execute the automatic wheel diameter calibration after confirming that the speed of the GPS is normal; 3) selecting different calibration speeds according to different difference values between the actual measurement speed and the GPS speed; 4) performing integral calculation on a difference value between the vehicle speed provided by the GPS and the actually measured vehicle speed of the speed sensor, and adding the calibrated wheel diameter difference value and the existing stored wheel diameter to obtain a calibrated wheel diameter value, and 5) storing the calibrated wheel diameter value within an allowable range after the shortest calibration duration is executed.

    本发明所述动车组自动轮径校准的控制方法,针对动车组由于磨耗或其它原因导致轮径实际值与控制系统内的轮径存储值发生变化,控制系统自动进行轮径校准,校准完成后自动存储,从而无需人工控制、手动输入新轮径,解决轮径数据失真、丢失后无法自动更新的问题。包括以下步骤:1)根据TCMS实时监控轨道车辆的运行状态,判断是否执行轮径自动校准;2)牵引控制系统检测并确认GPS的误差速度,在确认GPS速度正常后,执行自动轮径校准;3)根据实测速度与GPS速度差值的不同,选择不同的校准速度;4)对GPS提供的车辆速度与速度传感器实测车辆速度的差值进行积分计算,校准后的轮径差值与既有存储的轮径相加后,得出校准后的轮径值。5)在执行完最短校准持续时间后,将校准后在允许范围内的轮径值保存。
