机械式自动变速器的容错技术

随车诊断系统中应增强容错功能，即当有些部件失效时，它们在系统中的功能可由系统中的其它部件完全或部分代替，使系统保持规定的性能或不丧失最基本的功能，或维持在某故障状态下，使汽车返回维修点后再维修。详细介绍了机械式自动变速器容错控制系统的组成和功能。

The paper presents the constituent and function of fault tolerant control technique of mechanicalautomatic transmission in detail. In the on vehicle diagnostic system,fault tolerant function should be strengthened,that means the function of some comPOnents being invalid in a system can be totally or partly replaced by othercomponents while the originally specified performance can be still maintained or the substantial function not belost. Or in another case,to drive the car back to maintenance station to be repaired,keeping the invalid componentin a certain permissible condition.
