Abstract: This disclosure details cooling systems for cooling electric components, such as electric machines, within electrified vehicles. Exemplary cooling systems may include a spray bar positioned relative to a rear face of a stator of the electric machine. In some embodiments, the spray bar may be positioned axially between the rear face of the stator and a torque converter housing. One or more nozzles of the spray bar are configured to direct a coolant between adjacent back irons of the stator, onto end windings of the stator, or both. Actively cooling the stator allows the electric machine to operate at higher torques and speeds, thereby increasing performance.

Abstract: Methods and systems for an electric motor-generator in a vehicle are provided. In one example, an electric motor-generator is provided that includes an engine interface configured to rotationally couple to a first engine, a transmission interface configured to rotationally couple to a first transmission of the first engine, and a rotor with a plurality of magnets at least partially surrounding a stator including a plurality of coils. The rotor is rotationally coupled to the engine interface and the transmission interface.

Abstract: A vehicle includes a planetary gear set, a gearbox, an electric machine, and an engine. The planetary gear set has a sun gear, a carrier, and a ring gear. The gearbox is configured to transmit power from the ring gear to vehicle wheels. The electric machine is fixedly coupled to the sun gear. The engine is selectively coupled to the ring gear via a first selectable one-way clutch and selectively coupled to the carrier via a second selectable one-way clutch.

Abstract: A vehicle including a continuously variable transmission including a gear selectively locked to an output shaft via a clutch actuated by an electric coil. The vehicle also includes a controller configured to, in response to wheel hop being detected, energize the coil to disengage the clutch allowing the gear and the output shaft to rotate independently of each other.
