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

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.

摘要： A system and method for integrated electrification of vehicle accessories conventionally driven by an internal combustion engine includes an electric motor coupled to a common accessory drive that drive a plurality of accessories, such as a power steering pump, an air conditioning compressor, an air compressor, a thermodynamic heater and/or a coolant pump. The integrated electrified accessory unit preferably has the electric motor, accessory drive and accessories arranged in a common housing which is configured to be mounted to a chassis frame rail of the vehicle, the common housing including wall penetrations which facilitate rapid connection of the accessories to external lines of the vehicle.

摘要： A polygonal coupling couples torque source to a torque consumer such that input and output portions of the coupling may elastically rotate relative to one another during torque transfer to accommodate rotational speed variations in delivery of torque from the torque source. In an embodiment the torque source is an internal combustion engine with an integrated switchable coupling between the engine crankshaft and a torque transfer segment supporting a motor-generator. The polygonal coupling includes axially-overlapping polygonal-shaped male and female portions which cooperate to pass torque between the output of the integrated switchable coupling and an input of the torque transfer segment. At least one of the male and female portions includes recesses which form flexible arms adjacent to the lobes of the polygonal shape that allow the portions to rotate relative to one another over small angular displacements, and thereby improve damping of crankshaft rotational vibrations.

摘要： A system and method are provided for controlling the operation of a vehicle equipped with a hybrid electric front end motor-generator system during vehicle platooning operations to maintain a predetermined separation distance between vehicles in the vehicle platoon. The motor-generator is operated to generate vehicle acceleration and deceleration by outputting torque to an engine crankshaft to accelerate the vehicle or generating a regenerative braking load via the crankshaft on the vehicle, in place of the vehicle's internal combustion engine and braking systems, when the required vehicle accelerations and/or decelerations needed to maintain the desired vehicle separation distance are small and within the torque output or torque load capacity of the motor-generator. If the required vehicle acceleration or deceleration is greater than the motor-generator's available capacity, the motor-generator may be operated to provide a portion of the required acceleration or deceleration, as a supplement to the acceleration provided by the engine or the deceleration provided by the braking system. The use of a front end motor-generator system in this manner increases overall vehicle energy efficiency by decreasing fuel consumption and increasing the amount of electrical energy captured for storage during vehicle platooning operations.

摘要： A perimeter electric machine cooling arrangement includes a cooling conduit arranged to remove heat from an integrated housing containing an electric motor and a power inverter. The electrical connections between the electric motor and the power inverter are provided by flexible, pre-formed busbars that are arranged in pass over liquid cooling connections in the region between the electric motor and the power inverter. The integrated housing includes an intermediate cover over the electric motor and the power inverter portions of the housing, with a window through which the busbars can pass to reach the electric motor. The housing is further provided with an outer housing cover and seals that isolate the electric motor and the power inverter from the exterior environment and one another.
