    摘要: A vehicle includes a clutch set, a tank with fluid, an auxiliary battery, an electric fuel pump, and a controller. The electric fluid pump delivers some of the fluid from the tank to a designated oncoming clutch of the clutch set. The controller calculates a predicted flow value for the oncoming clutch during the shift event, and selectively controls the speed of the pump using the predicted flow value during the shift event. The controller controls the pump using an actual flow value when the vehicle is not executing a shift event, i.e., when holding torque. The speed of the electric fluid pump is increased to a first calculated speed determined using the predicted flow value when the shift event is initiated and before filling of the oncoming clutch commences, and is reduced to a second calculated speed determined using the actual flow value when the shift event is complete.

    摘要: A method of controlling a fluid pump to supply lubricating fluid to a plurality of fluid requiring components in a hybrid vehicle powertrain includes selecting a component-required flow rate for each respective component using a determined operating speed and torque for that respective component. Once the each component-required flow rate is selected, the system flow rate is set to the maximum component-required flow rate of the plurality of component-required flow rates. The fluid pump is then commanded to supply fluid to each of the plurality of fluid requiring components at the system flow rate.

    摘要: A fluid system includes a fluidic device, an electrically-actuated fluid pump having a pump motor, and a control system. The control system controls a speed of the pump using a commanded torque value, and calculates a feedforward torque term as a function of a set of operating values, including a desired fluid line pressure. The control system determines the speed control torque term using pump speed error, and adds the feedforward torque term to the speed control torque term to calculate the commanded torque value. The speed control torque term may be determined using an integral term of a proportional integral derivative (PID) portion of the control system. A method for controlling pump speed includes calculating the feedforward torque term, determining the speed control torque term using a pump speed error, and adding the feedforward torque term to the speed control torque term to calculate the commanded torque value.
