摘　　要：正确的发动机数据对电控机械式自动变速器(AMT)性能具有决定性影响。错误的数据会造成AMT错误的估算整车质量和道路坡道等,导致AMT换挡时发动机升速、换挡后冲击大等,错误的整车质量或坡道会导致换挡混乱、油耗高等。传统的方法在传动轴上贴应变片测量发动机扭矩复杂且昂贵。本文提出了一种方法"扭矩确认法"。该方法经过具体操作,验证该方法操作简单,测试结果可靠。the right of electronically controlled engine data automatic mechanical transmission（AMT） is crucial to performance.Wrong data can cause AMT error estimation of vehicle mass and road slope and so on,cause the AMT shift when the engine up and shift shock after the big error of the mass or the ramp will lead to shift chaos and high fuel consumption.Traditional method of strain gauge measuring the engine torque transmission shaft with complex and expensive.This paper proposes a method ＂torque confirm method＂.The method after a specific operation,verify that the method is simple,reliable test results.
