    Abstract: Methods and systems are provided for increasing an efficiency of a modular hybrid transmission (MHT) of a hybrid vehicle. In one example, a method for operating an MHT comprises, at one or more control modules, determining an upper torque bound and a lower torque bound of a feedback controller based on a feedforward (FF) engine torque value, the feedback controller controlling a torque of an electric motor of the hybrid vehicle; and constraining operation of the electric motor via the feedback controller based on the upper and lower torque bounds. The electric motor may be controlled by a hybrid powertrain control module of the MHT. The upper and lower torque bounds may be calculated at a powertrain control module of the MHT based on torque converter losses.

    Abstract: A vehicle includes a combustion engine configured to output mechanical power and an electric machine coupled to the engine and configured to convert the mechanical power to electrical power. The vehicle also includes a battery to exchange electrical power with the electric machine. The vehicle further includes a controller programmed to receive user inputs indicative of a desired storage duration and a storage location and monitor a battery state of charge (SOC) while the vehicle is stored. The controller is also programmed to prompt a remote user to approve an engine auto-start in response to the SOC depleting to less than a predetermined threshold during storage, and to auto-start the engine to generate power to recharge the battery in response to remote user approval. The controller is further programmed to inhibit the auto-start of the engine in response to the vehicle being stored in an enclosed storage location.

    Abstract: A vehicle includes an engine block heater, a traction battery, and a controller. The controller, responsive to a temperature being less than a threshold, charges the traction battery with grid energy until a state of charge of the traction battery achieves a charge target. The controller is further programmed to, responsive to the state of charge achieving the target, discharge the traction battery to power the engine block heater until the state of charge falls below a discharge target or the temperature achieves a temperature target. The controller is also programmed to, responsive to the charge falling below the discharge target, charge the traction battery with grid energy until the state of charge achieves the charge target. Additionally, the controller is programmed to, responsive to a temperature achieving a temperature target, inhibit charging and discharging the traction battery.

    Abstract: Methods and systems are provided for a door of an exhaust system of an engine. In one example, a door of an exhaust system may include an outer door pivotable around a first location and an inner door pivotable around a second location, with the inner door positioned within the outer door, and with an amount of opening of an aperture of the outer door adjustable by a position of the inner door.
