Abstract
Automated calibration of an automatic transmission design generates upshift scheduling curves in a throttle level/transmission output speed plane based upon laboratory-generated data and user generated drivability data. Downshift scheduling curves and torque converter lock-up and unlock curves are then generated as offsets from breakpoints on corresponding upshift curves, the offsets determined principally from the drivability data.
