- Title: Artificial Intelligence in the Automated Design of
- Automobile Power Transmissions:
- A Collaborative Research Project with Ford Motor Co.
- Time: Wednesday, November 25, 1992, at 2:00pm
- Place: MC 320
- Abstracts:
- This talk describes our system called TRANS-FORM for automating
- the process of designing automobile power transmissions. The work
- is being conducted in collaboration with the Ford Motor Company
- Advanced Transmission Design Department in Livonia, Michigan.
- Our current focus is on the design of the mechanical subsystem, but
- we anticipate extending this later to the electrical and hydraulic
- subsystems also.
-
- TRANS-FORM uses Constraint-Directed Reasoning to perform
- transmission design in a hierarchy of abstraction levels. These levels
- will ultimately include the functional, abstract state, kinematic,
- topological, stick-diagram, geometric and gearset levels. Design at
- three of these levels, kinematic, topological and gearset, has so far
- been implemented and will be described in this talk.
-
- TRANS-FORM has been able to rediscover all known transmission
- of the type explored, including the well-known Axod, HydraMatic
- 700 and Jatco transmissions as well as an extended version of the
- well-known Simpson transmission. These are built from two
- planetary gearsets and have four forward speeds and one reverse
- speed. Future generalizations will allow transmissions
- with three and four gearsets and an arbitrary number of speeds.
- Such transmissions are relatively little- explored, and the
- corresponding extensions to TRANS-FORM should allow it to be
- generating patentable new designs in the near future.
