  • Operating method for a hydraulic system of an automatic transmission
    Patent number: 11143292
    Abstract: A method for operating a hydraulic system for an automatic transmission includes determining a defined primary pressure value (p_PE) to be adjusted based on a measurement of an input current (I_22) of an electric motor and also includes adjusting a secondary flow rate (Q_SZ) to be adjusted based on calculation and adjustment of a target speed (n_Z) of the electric motor.
    Type: Grant
    Filed: June 1, 2018
    Date of Patent: October 12, 2021
    Assignee: ZF FRIEDRICHSHAFEN AG

  • Method to determine leakage of a hydraulic pump
    Patent number: 10774927
    Abstract: A method for detecting an oil leakage of a main pump during a stopping process of an internal combustion engine, where the oil leakage is caused by a reversal of a direction of rotation of a crankshaft of a vehicle including an electric auxiliary pump and the main pump, where the main pump is driven by the internal combustion engine of the vehicle. The method includes determining whether a rotational speed of the electric auxiliary pump exceeds a predefined threshold value, and when the rotational speed of the electric auxiliary pump exceeds the predefined threshold value for the rotational speed, detecting that the main pump is leaking, recording an error in an error memory of the vehicle, and demanding an engine start.
