In the never-ending quest of increased productivity, new methods of controlling gear and directional shifts in power-shift transmission-equipped vehicles are becoming desirable. Due to increased vehicle engine power, increased vehicle speeds, increased loads and shorter cycle times, currently used clutch shift modulation devices are not able to provide optimum clutch engagements under the variety of vehicle operational conditions encountered.This paper describes an electronic system developed for providing optimum clutch engagement control under any given vehicle operational condition. A description of clutch hardware, valving, torque and speed transducer, together with measuring and display devices monitoring vehicle performance, and representative test data are included.
