  • Shift energy management through repetitive garage shift detection
    Patent number: 11933395
    Abstract: Techniques for controlling an automatic transmission of a vehicle include receiving a set of operating parameters each relating to a rock cycling maneuver of the vehicle, the rock cycling maneuver comprising a plurality of consecutive garage shifts of the transmission, determining whether the set of operating parameters satisfy a set of entry or exit criteria to/from a rock cycling mode of the transmission and enter/exit the rock cycling mode based on the determination, while not in the rock cycling mode, controlling the transmission based on a first set of calibrations for the transmission, the first set of calibrations being optimized for normal garage shifts of the transmission, and while in the rock cycling mode, controlling the transmission based on a different second set of calibrations for the transmission, the second set of calibrations being optimized for the rock cycling maneuver.
