摘　　要：根据自动机械变速器(Automated Mechanical Transmission,AMT)的原理和特点,应用信号分析和解析冗余处理方法,研究和设计了AMT转速故障诊断及容错策略,并在Matlab/Simulink软件环境下搭建了某轮式车辆AMT转速故障诊断与容错系统控制模型,试验结果表明故障容错策略能有效地实现故障诊断和信号重构功能,大大提高了AMT系统的可靠性.The rotational speed signal of the Automated Mechanical Transmission （AMT） is researched based on the principles and characteristics of the AMT by the way of the signal analysis and the analytical redundancy method. The control model of the AMT rotational speed fault diagnosis and tolerance is constructed by the Matlab/Simulink platform. The test results indicate that the strategy of fault diagnosis and tolerance can realize the function of fault diagnosis and signal reconstruction, and effectively improve the driving ability of the AMT system under the fault condition.
