Matthew James Sirovatka has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Thermal management system and method of thermal management during transmission calibration
    Patent number: 10054032
    Abstract: A controller-implemented method for controlling a fan drive of a machine having a transmission is provided. The controller-implemented method may include generating a default fan speed for controlling the fan drive based on one or more operating conditions associated with the machine, generating an override fan speed based on one or more operating conditions associated with the transmission, and controlling the fan drive according to the override fan speed at least partially during calibration of the transmission.

  • Braking reduction using transmission control
    Patent number: 10024423
    Abstract: A braking reduction and transmission control system is implemented in a vehicle or machine having a power source and an automatic transmission connected by a torque converter providing a fluid coupling between a power source output shaft and a transmission input shaft. A lock-up clutch operatively connect to the torque converter is locked when the shafts are rotating at approximately the same speed. The braking reduction and transmission control system unlocks the lock-up clutch when operating conditions of the machine indicate that a transmission downshift will occur, such as when a combination of a brake input device displacement and a machine ground speed compared to a transmission downshift schedule indicate that the downshift will occur. Prior to downshifting the transmission and unlocking the torque converter, the drivetrain assists the service brakes in slowing the machine.
