ABSTRACT:
A down-shift acceleration resistance and a down-shift target acceleration are compared, and only when a deceleration intent by the driver is detected, is a down-shift to a gear ratio which is one step higher than a gear ratio which will produce deceleration in excess of that indicated necessary by the comparison, permitted. In the absence of any detected deceleration intent by the driver, a forcible downshifting is inhibited. The shifting is controlled through computation which does not rely on large amounts of prestored table data.
