  • Clutch controls for electric vehicle transmission with modular actuation system
    Patent number: 12146535
    Abstract: A vehicle includes a transmission that performs a method of operating a clutch of a vehicle. The vehicle includes the clutch, an actuator device and a processor. The actuator device includes a piston movable to operate the clutch. The processor is configured to receive a pressure signal indicative of a selected fluid pressure for operating the clutch, determine a position for the piston in the actuator device from the pressure signal, and move the piston to the position to operate the clutch at the selected fluid pressure.
    Type: Grant

  • Method and system for full cycle error correction of inductor current measurement for switching regulators
    Patent number: 11867788
    Abstract: Example implementations include a method of generating a ramp down compensation voltage based at least partially on the a current sense voltage and an inductor voltage of an inductor at an inductor node, applying the ramp down compensation voltage to the inductor node, and in accordance with a first determination that the valley current sense voltage and the inductor voltage are not equal, modifying a predetermined capacitance of a system capacitor operatively coupled to the inductor node to a first modified capacitance.
