    Abstract: An apparatus for calculating torque of a variable capacity compressor is provided. The compressor includes a suction chamber, a cylinder bore, a discharge chamber, a piston to draw coolant from the suction chamber into the cylinder bore, compress the drawn coolant, and discharge the compressed coolant into the discharge chamber, and a torque calculator. The compressor includes a clutch configured to be turned on to transmit driving force from a driving source to the piston so that the piston operates and to be turned off to disconnect the driving force of the driving source from the piston so that the piston stops. The apparatus comprises a pressure adjuster adjusting a back pressure introduced from the discharge chamber to the back of the piston and thereby adjust a stroke of the piston, and a capacity controller including a start-torque-calculate adminicle configured to provide the pressure adjuster with an external control signal for at least a predetermined time after the clutch is turned off, the external control signal being identical to a maximum capacity signal to establish a full piston stroke. The torque calculator has a start torque calculator configured to calculate a start torque of the compressor when the clutch is turned on.

    Abstract: A pump enable system includes a variable-displacement piston pump (10, 110) having a displacement control device (22, 122). The displacement control device (22, 122) controls displacement of pistons in the pump (10, 110) based on a position thereof, and a position control system (24, 26, 28, 124, 126) in the pump (10, 110) controls a position of the displacement control device (22, 122) based on a load on the pump (10, 110). An over-ride system (52, 152) selectively over-rides the position control system (24, 26, 28, 124, 126) such that the displacement control device (22, 122) assumes a position which reduces displacement of the pistons in the pump (10, 110).

    Abstract: Methods and systems for a variable displacement bent axis piston motor are described. In one example, a variable displacement bent axis piston motor comprises a bent axis unit (BAU) rotary group including a cylinder block coupled to a drive shaft of the bent axis piston motor, and an electric actuator coupled to a servo piston of the bent axis piston motor, wherein a displacement of the BAU rotary group is controlled by an inclination angle between the drive shaft and a valve plate of the BAU rotary group coupled to the cylinder block, the inclination angle controlled by the servo piston, the servo piston controlled by the electric actuator. The servo piston is controlled by the electric actuator based a feedback control system, which may switch between various control strategies for adjusting the inclination angle based on different driving scenarios.

    Abstract: A method controls the start-up of an oil pump of a gearbox by a brushless electric motor that has no position sensor. The stator coils are powered from the off mode in a constant-current open-loop control sequence until the pump reaches a speed threshold at which speed regulation switches over to closed-loop control on a setpoint corresponding to the lubrication flow rate required to ensure the reliability of the gearbox, but without in so doing exceeding a current threshold indicative of pump seizure, at which point motor control switches back over to the constant-current open-loop control sequence. The open-loop current setpoint is higher than the threshold for switching over to closed-loop control so that in the open-loop control mode the motor torque available at the pump is higher than in the closed-loop control mode.
