    摘要： A method of calibrating a hydraulically operated park brake of a continuously variable transmission of a vehicle. With the vehicle moving at a set, slow speed within a specified range, and the park brake off, a search technique is used, wherein the brake hydraulic pressure is reduced by application of a control signal of a selected test value to apply the brake. When the selected test value is reached, it is held constant, and a condition in a HSU of the transmission is monitored for a change indicative of engagement of the park brake. This will expectedly be in the form of a pressure change and more particularly an increase indicating initial contact between the plates of the brake, and if the HSU change is not detected, the step will time out and another control signal value will be tested.

    摘要： The method of estimating and controlling driveline torque in a continuously variable hydro-mechanical transmission uses pressure data and other metrics of a hydrostatic power unit of the transmission in lieu of actual driveline torque data. A mechanical efficiency of the transmission is determined as a function of whether the power unit is operating in a power generation or regeneration mode, and the torque output of the power unit is estimated from that and other hydrostatic parameters. This is used to estimate a torque output of a planetary power unit of the transmission, and the torque on an output member of the driveline is then estimated using that value, and appropriate corrective action taken.

    摘要： A parking brake is controlled in concert with operation of a hydrostatic power unit of a continuously variable transmission, particularly when engaging, disengaging and shuttle shifting the transmission, to provide advantages, particularly when on hills. When particular commands are received, such as shifting to a non-moving position, the parking brake is automatically engaged to hold the vehicle position. A swash plate of the hydrostatic unit can be automatically positioned to anticipate the next command. If that command is received, the brake is automatically gradually or proportionally released and the transmission engaged to effect the commanded movement of the vehicle. If a different command is received, the brake remains engaged as the transmission is configured for the commanded movement, such that no machine movement results. Then the brake is automatically gradually or proportionally released and the transmission engaged to effect that commanded movement.
