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.

Abstract: A method for generating an acceleration profile for a valve operating cam of an internal combustion engine varies an adjustment point of an initial draft acceleration profile curve such that a determinant of a set of equations defining valve motion constraints and scaling factors is forced to zero. The equations may then be solved for values of the scaling factors which are applied to the initial draft acceleration profile curve to generate a desired profile which satisfies valve motion constraints.
