| 摘 要： | 分析了某款液力机械式自动变速器液压系统的工作原理及其电磁阀特性,设计制作了变速器电控单元(TCU),制定上下位机CAN通信协议,编写下位机flash控制代码,开发了基于LabVIEW的标定系统上位机软件,并以15％油门开度下1挡升2挡标定为例进行了实车试验.结果表明,该变速器换挡最大冲击度降到了8.34 m/s,相对标定前降低了约63％,从而验证了标定系统的正确性.

| Abstract: | Operating principle and its solenoid valve characteristic of a hydraulic AMT hydraulic system are analyzed,and a TCU is designed.Then,based on the communication protocol of CAN,a flash operation code of the lower computer is made and an upper computer calibration program is edited in LabVIEW.Finally,an onboard test is conducted to 1-2 shifting with 15% throttle opening.The test results show that the maximum shifting impact strength of this transmission drops to 8.34m/s,approx.63% lower than that before calibration,thus proving correctness of the calibration system. |
