    Abstract: Disclosed is a method for real time determination of a base torque value, representative of maximum available torque of an engine at a specified engine rpm, as a function of engine torque during predetermined engine conditions. The base torque value is used to determine shift points for an automatic transmission of an self propelled work machine.

    Abstract: A system for controlling the header speed of a windrower to a set point includes a variable displacement pump producing a variable outflow of hydraulic fluid for driving the header via two hydraulic motors, the system being characterized in that the pump is driven by a pulse width modulated (PWM) signal having a duty cycle that is dependent on the speed and the acceleration of the header. When the header speed falls outside a window or range of speeds centered at the set point, header speed is used to modify the duty cycle of the PWM signal and bring the header speed back within the window. In addition, the duty cycle of the PWM signal is decremented if the acceleration of the header exceeds a threshold and the header includes disk type cutters.

    Abstract: 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.

    Abstract: 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.
