摘要： A hydraulic excavator (1) includes a hydraulic pump (22) driven by an engine (20), an electromagnetic proportional valve (24) for hydraulic pump that adjusts pump torque of the hydraulic pump (22) in response to a pump torque target value (Tp), a hydraulic actuator operated by a delivery pressure of the hydraulic pump (22), a motor generator (30) connected to the engine (20), and a controller (26) configured to calculate the pump torque target value (Tp). The controller (26) acquires a pump torque adjustment amount (Qadj) based on a deviation (ΔAH) between a current integrating value (AH1) acquired by integrating a value of a current flowing into the motor generator (30) when the hydraulic actuator is driven and a current integrating reference value (AH0).

摘要： A system and method are provided for hybrid electric internal combustion engine applications in which a motor-generator, a narrow switchable coupling and a torque transfer unit therebetween are arranged and positioned in the constrained environment at the front of an engine in applications such as commercial vehicles, off-road vehicles and stationary engine installations. The motor-generator is preferably positioned laterally offset from the switchable coupling, which is co-axially-arranged with the front end of the engine crankshaft. The switchable coupling is an integrated unit in which a crankshaft vibration damper, an engine accessory drive pulley and a disengageable clutch overlap such that the axial depth of the clutch-pulley-damper unit is nearly the same as a conventional belt drive pulley and engine damper. The front end motor-generator system includes an electrical energy store that receives electrical energy generated by the motor-generator when the coupling is engaged. When the coupling is disengaged, the motor-generator may drive the pulley portion of the clutch-pulley-damper to drive the engine accessories using energy returned from the energy store, independent of the engine crankshaft.
