An electrified drivetrain for a vehicle includes a first electric machine, a second electric machine, a clutch, an HVAC compressor, and a controller. The second electric machine is rotatably coupled to a geartrain, the first electric machine is rotatably coupled to the HVAC compressor, and is rotatably couplable to the geartrain via the clutch, and the clutch is operative in a first state and a second state. The first electric machine is rotatably coupled to the geartrain when the clutch is controlled to the first state, and is decoupled from the geartrain when the clutch is controlled to the second state. The controller is operatively connected to the first and second electric machines, the clutch, and the HVAC compressor to control operation of the electrified drivetrain. The first electric machine can be used as a heater element and to provide mechanical power to the drivetrain.
Description
technical field [0001] The present invention relates to electrified powertrains for vehicles. Background technique [0002] Vehicles employing electrified powertrains require on-board devices that provide auxiliary functions, such as HVAC (Heating Ventilation Air Conditioning, ie, Heating-Ventilation-Air Conditioning) devices including air-conditioning compressors and heater cores. On vehicles with an internal combustion engine, such functions are provided by an accessory device driven by an accessory belt drive and by a coolant circulation system including a radiator and other heat exchangers. On electrified vehicles, coolant circulation systems and accessory belt drive systems may not be available and such functions may be provided by separate systems including, for example, separate electric motors that drive the air conditioner compressor and electric radiant heat generators. Such stand-alone systems consume packaging space, add complexity to the wiring harness, add wei...
