  • Power dissipation management system
    Patent number: 6986554
    Abstract: A method and apparatus for a power dissipation management system for a vehicle where a thermal condition of a plurality of driveline components is determined. The quantity of energy for each driveline component can absorb is determined based upon its thermal condition. A braking signal to one or more of the driveline components is provided based upon the quantity of energy each component can absorb.

  • Method and system for an adaptation of an engagement of an automated clutch
    Patent number: 6971971
    Abstract: A clutch is operated by an actuating pressure pressure during an engaging process of the clutch. The actuating pressure is controlled over time such that predetermined characteristics for an engagement of said clutch are approximated by starting a process for changing a rotational speed of an output shaft of the torque converter for an adaptation of the rotational speed to an actual velocity of the vehicle during engagement of the clutch. An ideal signal for the rotational speed is determined which corresponds to an estimate for an engagement of the clutch with the predetermined characteristics. An actual signal of the rotational speed of the output shaft over time is measured during said process. Deviations are determined between the actual signal and the ideal signal. Finally the signal of the actuating pressure over time is automatically changed in order to reduce the deviations between the actual signal and the ideal signal if the deviations exceed a threshold.
