摘要： A method for controlling PTO clutch engagement includes determining a first change in clutch speed based on an inertial load of a PTO implement. The method also includes determining a second change in clutch speed based on a threshold amount of energy of a PTO clutch. The method further includes determining a third change in clutch speed between the first change in clutch speed and the second change in clutch speed. The method also includes adjusting a clutch current based on the third change in clutch speed.

摘要： A system includes an engine, a transmission driven by the engine, and a controller. The controller is configured to receive a speed input, receive feedback indicative of a load of the engine at a current engine speed, compare the load to a predetermined load threshold at the current engine speed, determine an expected engine speed based at least on the current engine speed, a current gear ratio, and an expected gear ratio, determine an estimated engine power at the expected engine speed and a current engine power at the current engine speed, and command a gear downshift when the load is greater than or equal to the predetermined load threshold and when the estimated engine power is greater than the current engine power.

摘要： A steady voltage is generated which is proportional to the quotient of the rotational rates of the two members for which it is desired to determine the slip rate. The apparatus may be used to effect coupling of the two members when the slip rate falls to or very near zero, particularly in a motor vehicle transmission. The control voltage is generated by first generating, through electrical sensors and circuits, a train of pulses having a repetition rate proportional to the rotational rate of one of the members and having a pulse width inversely proportional to the rotational rate of the other of the members, and then integrating the pulse train to provide a steady control voltage.
