The engine includes an output. The motor includes a rotor and a stator. The transmission includes an input that is rotatably coupled to the rotor. The transmission is configured to receive power from the engine and the motor. The electronically controlled one-way clutch has an inner race that is secured to the output of the engine and an outer race that is secured to the rotor. The electronically controlled one-way clutch is configured to rotatably couple the output to the rotor. ## Claims ### Claim 1 A vehicle comprising: an engine having an output; a motor having a rotor and a stator; a transmission having an input rotatably coupled to the rotor and configured to receive power from the engine and motor; and an electronically controlled one-way clutch having an inner race that is secured to the output and an outer race that is secured to rotor. ### Claim 2 (depends on 1) The vehicle of claim 1, wherein the electronically controlled one-way clutch includes a first set of rockers secured to the inner race that are configured to engage a first set of notches in the outer race to rotatably couple the output to the rotor in a first direction of rotation. ### Claim 3 (depends on 2) The vehicle of claim 2, wherein the electronically controlled one-way clutch includes a first coil that energizes and de-energizes to transition the first set of rockers between a first extended position to engage the first set of notches and a first retracted position to disengage the first set of notches. ### Claim 4 (depends on 3) The vehicle of claim 3, wherein the electronically controlled one-way clutch includes a second set of rockers secured to the inner race that are configured to engage a second set of notches in the outer race to rotatably couple the output to the rotor in a second direction of rotation opposite of the first direction of rotation. ### Claim 5 (depends on 4) The vehicle of claim 4, wherein the electronically controlled one-way clutch includes a second coil that energizes and de-energizes to transition the second set of rockers between a second extended position to engage the second set of notches and a second retracted position to disengage the second set of notches. ### Claim 6 (depends on 1) The vehicle of claim 1, further comprising a case disposed between the engine and the transmission that houses the motor and fluidly isolates the rotor from the transmission. ### Claim 7 (depends on 6) The vehicle of claim 6, further comprising channels in fluid communication with the stator and the transmission, wherein the channels are configured to direct transmission fluid to the stator to cool stator coils. ### Claim 8 A powertrain module comprising: a housing; an input shaft extending from the housing and configured to rotabably couple to an engine output; an output shaft extending from the housing and configured to rotatably couple to a transmission input; a motor having a stator secured to an inner surface of the housing and a rotor secured to the output shaft; and an electronically controlled one-way clutch having an inner race that is secured to the input shaft and an outer race that is secured to the rotor. ### Claim 9 (depends on 8) The powertrain module of claim 8, wherein the electronically controlled one-way clutch includes a first set of rockers secured to the inner race that are configured to engage a first set of notches in the outer race to rotatably couple the input shaft to the rotor in a first direction of rotation. ### Claim 10 (depends on 9) The powertrain module of claim 9, wherein the electronically controlled one-way clutch includes a first coil that energizes and de-energizes to transition the first set of rockers between a first extended position to engage the first set of notches and a first retracted position to disengage the first set of notches. ### Claim 11 (depends on 10) The powertrain module of claim 10, wherein the electronically controlled one-way clutch includes a second set of rockers secured to the inner race that are configured to engage a second set of notches in the outer race to rotatably couple the input shaft to the rotor in a second direction of rotation opposite of the first direction of rotation. ### Claim 12 (depends on 11) The powertrain module of claim 11, wherein the electronically controlled one-way clutch includes a second coil that energizes and de-energizes to transition the second set of rockers between a second extended position to engage the second set of notches and a second retracted position to disengage the second set of notches. ### Claim 13 (depends on 8) The powertrain module of claim 8, wherein the housing includes a rear wall that includes an orifice, and wherein the output shaft extends through the orifice. ### Claim 14 (depends on 13) The powertrain module of claim 13, wherein a seal is disposed between the rear wall and the output shaft to prevent fluid from flowing from an external side of the rear wall to an internal side of the rear wall. ### Claim 15 (depends on 13) The powertrain module of claim 13, further comprising channels in fluid communication with the stator and an external side of the rear wall. ### Claim 16 An electric machine comprising: a stator; a rotor disposed within the stator and secured to an output shaft; an input shaft disposed within the rotor; and an electronically controlled one-way clutch having an inner race that is secured to the input shaft and an outer race that is secured to the rotor. ### Claim 17 (depends on 16) The electric machine of claim 16, wherein the electronically controlled one-way clutch includes a first set of rockers secured to the inner race that are configured to engage a first set of notches in the outer race to rotatably couple the input shaft to the rotor in a first direction of rotation. ### Claim 18 (depends on 17) The electric machine of claim 17, wherein the electronically controlled one-way clutch includes a first coil that energizes and de-energizes to transition the first set of rockers between a first extended position to engage the first set of notches and a first retracted position to disengage the first set of notches. ### Claim 19 (depends on 18) The electric machine of claim 18, wherein the electronically controlled one-way clutch includes a second set of rockers secured to the inner race that are configured to engage a second set of notches in the outer race to rotatably couple the input shaft to the rotor in a second direction of rotation opposite of the first direction of rotation. ### Claim 20 (depends on 19) The electric machine of claim 19, wherein the electronically controlled one-way clutch includes a second coil that energizes and de-energizes to transition the second set of rockers between a second extended position to engage the second set of notches and a second retracted position to disengage the second set of notches.
