Abstract: A lubricant management system is provided for a work vehicle transmission. The system includes a balance piston contained in a balance piston cavity configured to receive fluid under pressure and provided between a clutch piston and a balance piston; a cooling fluid shutoff piston mounted in a passageway of the clutch piston; a valve configured to control pressure of fluid flow into the clutch piston cavity; and a controller, having processing and memory architecture, operatively coupled to the valve and configured to command the valve to adjust the pressure of the fluid flowing into the clutch piston cavity during operation of the clutch assembly. The passageway has a lubrication supply opening that is closed by the cooling fluid shutoff piston when a first pressure is within the clutch piston cavity.

Abstract: A hybrid vehicle controller for controlling a hybrid vehicle including a hybrid system is provided. The hybrid system includes an engine, a motor generator, a battery configured to supply power with the motor generator, a clutch configured to connect the engine to the motor generator, and a relay configured to connect the motor generator to the battery. The hybrid vehicle controller includes processing circuitry. The processing circuitry is configured to execute, when an operation requesting opening of the relay is performed, a process that releases the clutch, a negative torque application process that applies a negative torque, which is a torque for lowering a rotational speed of the motor generator, to the motor generator, after releasing the clutch, and a process that releases the relay when the rotational speed of the motor generator becomes less than a threshold.

Abstract: A method for calibrating engine clutch delivery torque of a hybrid vehicle includes: determining an engagement control amount of an engine clutch which connects an engine with a driving motor or disconnects the engine from the driving motor based on a difference between speeds of the engine and the driving motor; determining a current delivery torque corresponding to the engagement control amount of the engine clutch that controls the engine clutch to be in a lock-up state and a temperature of the engine clutch; extracting a previous delivery torque that corresponds to the engagement control amount that controls the engine clutch to be in the lock-up state and the temperature and is included in a map table; and applying a weighted value to each of the extracted previous delivery torque and the determined current delivery torque to calibrate the delivery torque included in the map table.

Abstract: Apparatus (control device) and a method for controlling a torque transmitting device such as a brake, wet clutch, dry clutch (10) during a filling and slip phase is provided, e.g. for coupling a first shaft (12) to a second shaft (14) via the wet clutch (10). A reference profile (52) for a control variable is provided, wherein the chronological progress of said control variable influences the position of a piston (22) for actuating clutch elements (16, 18). Each clutch element (16, 18) is connected to the first shaft (12) or the second shaft (14), with respect to a cylinder (20) of the wet clutch (10), and the control variable is determined during each coupling and a valve (38) for applying a pressure source to the piston (22) is operated, wherein the valve (38) is controlled during each coupling by means of a feed forward closed loop control (54) such that the control variable follows the reference profile (52). Due to the increased control quality by considering non-linear effects by means of the reference profile (52) for the feed forward closed loop control (54) at every coupling through learning, the coupling time can be shortened without increasing the risk of an uncomfortable coupling behavior.
