Patent ID: 6879900

Claim:
A method of controlling an automatic transmission of a motor vehicle during a spontaneous accelerator pedal release (FastOff) by a vehicle operator, the method comprising the steps of: storing at least one shifting characteristic field in an electronic transmission control; feeding a signal proportional to a position of the accelerator pedal to the electronic transmission control; detecting the spontaneous accelerator pedal release (FastOff) when a pedal position gradient (PSTG) is smaller than a pedal gradient threshold (KF_PSTG); and activating an upshift block mode (FFO=1); and exiting the upshift block mode (FFO=1) upon detection of a traction operation when an actual engine torque (MMM) exceeds a push-pull characteristic line (KL_ZS) stored as a function of a value equivalent to an engine rotational speed (NMO) depending on a vehicle acceleration/deceleration (AIST) relative to an overall tractional resistance (GFW) and the pedal gradient threshold (KW_PSTGPOS, KW_PSTGNEG).
