Abstract
A method of adaptively scheduling an upshift. The method determines whether the vehicle can maintain speed in a high gear and, if it cannot, to inhibit the lower to higher gear upshift. This is accomplished by observing vehicle acceleration in the lower gear, determining whether the vehicle will be capable of providing a predetermined value of acceleration after an upshift of the gear assembly to a higher gear. If the vehicle will not be capable of providing the predetermined value of acceleration, then the upshift will be prevented.
