摘要： Transmissions, control systems for transmissions, and methods of operating transmissions are disclosed. A transmission includes an input shaft, an output shaft, one or more clutches, and a control system. The input shaft is configured to receive rotational power supplied by a drive unit. The output shaft is coupled to the input shaft and configured to provide rotational power supplied to the input shaft to a load. The one or more clutches are coupled between the input shaft and the output shaft to selectively transmit rotational power between the input shaft and the output shaft in one or more operating modes of the transmission. Each of the one or more clutches is selectively engageable in response to one or more fluid pressures applied thereto. The control system is configured to control operation of the one or more clutches to select the one or more operating modes of the transmission.

摘要： The present invention provides a method of selecting and implementing a shift schedule for a transmission in a vehicle that includes an output speed sensor and a controller. The method includes measuring output speed with the output speed sensor and comparing the measured output speed to an output speed threshold. The controller receives throttle percentage and compares the throttle percentage to a throttle threshold. The method also includes calculating output acceleration and transmission gear ratio with the controller. The shift schedule is selected based on the measured output speed, calculated output acceleration, calculated transmission gear ratio, and throttle percentage.

摘要： The present disclosure provides a method for increasing a volume of hydraulic fluid in a reservoir of a transmission. The method includes providing a retarder mounted to the transmission, an accumulator including an internal cavity, a piston disposed in the internal cavity of the accumulator, a solenoid, a valve, and a controller. The method also includes enabling the solenoid from an off state to an on state, transferring fluid pressure from the valve to the piston, and moving the piston from a first position to a second position in the internal cavity. The method further includes discharging an amount of hydraulic fluid from the internal cavity of the accumulator to the reservoir and increasing the volume of hydraulic fluid in the reservoir.
