Microcomputer Mechanical Clutch and Transmission Control 840055

AN ELECTRONIC CONTROLLED FULL AUTOMATIC TRANSMISSION has been developed. Automatically controlled dry clutch and synchromeshed gear transmission make driving easier, maintaining better fuel efficiency of a mechanical transmission. The electronic control, similar to use of manual transmission, and H-pattern floor shift type “selector lever,” only for electric input device, make it possible for the driver to choose either of two types of driving - “sporty driving” of a manual transmission and “easy driving” of an automatic transmission. In the automatic mode, the microprocessor makes it possible to have stop-and-go operation that is so troublesome with a dry clutch. Adoption of a new brake system improves safety on ascending grade starts without torque converters.
This paper describes the system, in some detail on following subjects;
  • Clutch and Transmission Actuators
  • Sensors and Electronic Control Unit
  • System Control Strategy
  • Running Data
