  • Model-based torque converter control
    Patent number: 7752021
    Abstract: A method of controlling hydraulic pressure to a torque converter is provided. The method includes: determining a slip error from a target slip value and a measured slip; integrating said slip error; determining a state space feedback control matrix for said measured slip; determining a state space feedback control matrix for said integrated slip error; and controlling pressure based on said state space feedback control matrix for said measured slip and said state space feedback control matrix for said integrated slip error.
    Type: Grant
