Electronic Control Of Automobile Powertrain

As an innovative transmission which is more fuel/power efficient and easier to operate, several types of “automatic,” transmission or clutch have been developed by automotive manufacturers using a mechanical gear-type transmission with a dry clutch by the conbination with microcomputer-controled actuators. We have been developing, with favorable test results obtained so far, a full automatic gear-type transmission, with its production manual transmission used, by incorporating its newly designed hydraulic clutch and transmission actuators for attainment of optimum transmission function control. This paper outlines its working system and clutch control mechanism.
