  • System and method for fast fill of accumulator for automatic transmissions
    Patent number: 9771955
    Abstract: A system and method for fast fill of a hydraulic accumulator used in an automatic transmission includes providing an active fast fill mechanism fluidly connected to a hydraulic accumulator and a hydraulic system of the automatic transmission, providing an electronic control module in communication with the active fast fill mechanism, activating, by the electronic control module, the active fast fill mechanism to allow the hydraulic accumulator to fill with fluid from the hydraulic system, filling, by the active fast fill mechanism, the hydraulic accumulator with fluid, and de-activating, by the electronic control module, the active fast fill mechanism to stop filling the hydraulic accumulator with fluid from the hydraulic system during stop/start engine events of a vehicle.
