Abstract: A work vehicle and energy storage device include an electric machine having a stator and a rotor. The rotor is configured to rotate from the flow of electrical current provided to the electric machine, rotate to store energy of the work vehicle, provide a rotor mass to an end of the work vehicle, and generate electrical current for the work vehicle from rotation of the rotor. The rotor mass is greater than a stator mass.

Abstract: A control device for a vehicle including an internal combustion engine and an electric rotary machine connected to the internal combustion engine in a power-transmittable manner is able to perform torque-down through ignition delay control for delaying an ignition timing of the internal combustion engine and regeneration control for performing regeneration using the electric rotary machine when there is a torque-down request based on a vehicle state. The control device is configured to perform torque-down corresponding to a deficiency by delaying the ignition timing of the internal combustion engine when an actual torque of the electric rotary machine through the regeneration control is deficient for the torque-down request.

Abstract: A powertrain has an internal combustion engine provided with an accessory transmission that includes a first pulley connected to a crankshaft of the engine, a second pulley connected to a shaft of an electric machine, and a belt connecting the first and the second pulleys to each other to rotate in the same direction of rotation (R). The electric machine is operated to supply an active torque to the second pulley during start-up of the internal combustion engine by means of a starter motor.

Abstract: Aspects of the present invention relate to a control module (15) for a vehicle powertrain. The powertrain comprises a transmission (14), an engine (12) and an electric machine (16). The control module (15) is configured to receive an input indicative of a requested upshift and in response to the received signal the control module (15) increases the torque output of the engine (12) prior to the start of the torque phase (20). As the torque output of the engine (12) increases the control module (15) decreases the torque output of the electric machine (16) such that a constant wheel torque is applied to the wheels (18) during the torque phase (20) of the upshift.

Abstract: Aspects of the present invention relate to a control system 12, method 400 and computer program 31 for controlling torque provided by a belt integrated starter generator 14 of a vehicle 10, the control system 12 comprising one or more electronic controllers 18, the one or more electronic controllers configured to: determine a change in torque to be provided by the belt integrated starter generator 14 according to a torque request 54; determine that the change in torque will cause the belt integrated starter generator 14 to enter a torque reversal region 51; and generate and output to the belt integrated starter generator 14 an altered torque request 56 within the torque reversal region 51, wherein the altered torque request 56 is generated and output to the belt integrated starter generator 14 when the torque request 54 would result in a reduction in the amount of torque provided by the belt integrated starter generator and when the torque request would result in an increase in the amount of torque provided by the belt integrated starter generator.

Abstract: A hybrid power transmission mechanism includes an engine; a motor/generator having a rotor and a stator; a driven machine; a planetary gear mechanism having a sun gear, an internal gear drivingly connected to the rotor, a planetary gear, and a planetary carrier shaft including first and second extension shaft parts extending from the planetary gear in opposite directions; a first clutch switchable between a state of allowing transmission of power between the first shaft and the internal gear and a state of not allowing transmission of power therebetween; and a second clutch switchable between a state of allowing rotation of the sun gear and a state of not allowing rotation thereof. A first shaft that outputs power of the engine and a second shaft that inputs power to the driven machine are drivingly connected to the first and second extension shaft parts of the planetary carrier shaft, respectively.
