    摘要: An engine clutch transfer torque determining apparatus of a vehicle includes: a power source including an engine and a driving motor; an engine clutch that is located between the engine and the driving motor to selectively connect the engine to the driving motor; and a vehicle controller that controls release or engagement of the engine clutch to implement a driving mode, wherein the vehicle controller releases a clutch hydraulic pressure in the engine clutch when a running state of the vehicle satisfies a transfer torque determining advancing condition, controls a speed of the motor and a speed of the engine while maintaining a speed difference between the motor and the engine in a predetermined relative speed range, and determines a transfer torque of the engine clutch based on a clutch hydraulic pressure and a clutch input torque when the engine clutch slips.

    摘要: A vehicle transmission includes a plurality of oncoming clutches that are hydraulically-actuated. A controller is operatively connected to the plurality of oncoming clutches. An algorithm stored on and executable by the controller causes the controller to determine if at least one predefined coast condition is met and identify the plurality of oncoming clutches configured to be engageable during a downshift event from an initial gear ratio to respective other gear ratios. The initial gear ratio is greater than each of the respective other gear ratios. The algorithm causes the controller to generate a first pressure command to at least partially pressurize a first one of the oncoming clutches to a first staging pressure (PS1) if the at least one predefined coast condition is met prior to the downshift event. The first staging pressure (PS1) is defined as a first return spring pressure (PR1) minus a first variable correction factor (CF1).

    摘要: A control system for the transmission of an agricultural vehicle or an industrial off-highway vehicle, wherein the system comprises a controller of the clutch, connected thereto to supply an operating signal, a plurality of sensors suitable for measuring a plurality of characteristic quantities of the transmission and connected to the controller to supply a plurality of signals proportional to the quantities, a torque processor suitable for calculating a reference torque and connected to the controller to supply thereto a signal proportional to the reference torque, and a thermal load managing device suitable for receiving at least some of the plurality of quantities and for receiving the reference torque in order to calculate at least one operative datum on which the thermal power exchanged in the clutch is dependent. The control system is suited to process the operative datum to operate the transmission so as to limit the temperature in the clutch.
