摘要： The present invention comprises: a synchronization start determination unit 110 for determining a synchronization start of a synchronization device 70; a half-clutch determination unit 130 for determining whether a clutch device 20 is in a half-clutch state where the clutch device has not been switched from a connection state to a disconnection state; and a damage determination unit 140 which, when the synchronization start determination unit 110 has determined the synchronization start and if the half-cutch determination unit 130 has determined a half-clutch state, determines that damage is applied to the synchronization device 70 caused by the differential rotation between the power transmitted from a driving force source 10 side via the clutch device 20 and the power transmitted from a driving wheels 16L, 16R side.

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 method of a dual clutch transmission, a dual clutch transmission, and a vehicle equipped with the same which can reduce the load on a clutch on a start gear side to reduce the wear thereof and therefore make the clutch replacement interval longer. There are a first input shaft configured to be connected to a first clutch and a second input shaft configured to be connected to a second clutch. A set of odd-numbered gears and a set of even-numbered gears are arranged respectively across the first input shaft and second input shaft and an output shaft. When a vehicle starts, an absorbed energy Eabs by the second clutch is calculated while a start gear is partially connected to the second input shaft. The first clutch is partially connected (half clutch state) to the first input shaft, to which a support gear is synchronously engaged, when the absorbed energy exceeds a set value which is a predetermined threshold, the support gear having a gear ratio greater than that of the start gear by one speed or higher.
