Abstract
In an automotive transmission, a method for determining whether an upshift should be enabled or disabled determines the predetermined upshift vehicle speed at which the upshift is scheduled to occur with reference to current throttle position and vehicle speed. The method employs the difference between upshift vehicle speed and current vehicle speed, the current vehicle acceleration, an empirically determined upshift vehicle acceleration referenced to current vehicle speed and the speed difference. If the current vehicle acceleration is equal to or greater than upshift vehicle acceleration, the upshift is enabled; otherwise, the scheduled upshift is disabled.
