Systems and methods for operating a hybrid vehicle having an internal combustion engine are presented. In one example, the internal combustion engine is operated in a speed control mode and torque of an electric machine is adjusted so that a possibility of an engine speed controller saturating may be reduced.

System and method for detecting and correcting engine speed controller saturation

Systems and methods for operating a driveline of a hybrid vehicle are presented. In one example, torque capacity of a driveline disconnect is coordinated with torque control of an electric machine immediately following engine starting. The electric machine and the driveline disconnect clutch may assist starting of an engine, or alternatively, the engine may be started via a starter motor.

System and method for coordinating disconnect clutch and electric machine torque

Systems and methods for operating a hybrid vehicle during an end of assembly line test are presented. In one example, torque of an integrated starter/generator (ISG) is adjusted so that the ISG may not affect engine data that is collected during end of assembly line engine testing. The collected engine data may be a basis for adapting engine operation.

System and method for completing a neutral profile learning test

Systems and methods for operating a hybrid vehicle are presented. In one example, an integrated starter/generator (ISG) provides torque to restart an engine after the engine has been shut down and before engine speed is zero. An opening of a throttle is delayed to reduce driveline torque disturbances during engine restarting.

System and method for restarting an engine

Methods and systems are provided for electrical power distribution. In one example, a system includes plurality of electric consumers comprising one or more operating modes with different levels of power consumption, an energy storage and an electric machine arranged in the vehicle and configured to provide energy to the energy storage device or power to the electric consumers and torque to wheels of the vehicle, a power allocating device coupled to the energy storage device and the plurality of electric consumers, and a controller configured to maintain two indices for allocating power to the plurality of electric consumers, wherein a first index comprises a first power allocation strategy based on power from only the energy storage device and a second index comprises a second power allocation strategy based on power from the energy storage device and the electric machine.

Method of controlling electric load shedding in a vehicle

Systems and methods for starting an internal combustion engine of a hybrid vehicle are presented. In one example, the internal combustion is started via closing a driveline disconnect clutch and limiting a torque output rate of an electric machine so that vehicle speed may increase continuously without decreasing during engine cranking and run-up periods.

Systems and methods to coordinate clunk and shuffle management with engine starts in MHT drivetrains

Methods and a system are provided for shaping a torque profile for a motor of a hybrid vehicle. In one example, the method includes during a vehicle launch, an off condition of an engine, and upon receiving an engine start request, predicting a time of engine engagement, predicting a driver requested torque at the engine engagement; and reducing the driver requested torque until the predicted time of engine engagement based on the predicted driver requested torque at the engine engagement. The predicting of at least one of the time of engine engagement and the driver requested torque at the engine engagement may be based on a current position of an accelerator pedal and a driver profile. The method may further include controlling motor torque profile based on the reduced driver request torque.

Method for shaping motor torque profile during a launch engine start

Systems and methods for performing closed-in-bore diagnostics for a hybrid vehicle are presented. In one example, select operating conditions may be evaluated before closed-in-bore diagnostics may be initiated. In addition, charging of one or more batteries may be reduced to ensure that an engine throttle may operate with a small opening amount to evaluate the presence or absence of sludge in the engine throttle.

System and method for close-in-bore learning for a hybrid vehicle

Systems and methods for transitioning a hybrid vehicle from park or neutral to drive or reverse are presented. In one example, a requested engine speed is adjusted in response to a transmission disengaging indication and a transmission disengaging timer when a transmission is being disengaged from a gear. In another example, the requested engine speed is adjusted in response to a transmission engaging indication and a transmission engaging timer when the transmission is being engaged to a gear.

System and method for smooth transmission engagement and disengagement

A method and system for operating a vehicle that includes an integrated starter/generator and a driveline disconnect clutch is described. In one example, the method estimates engine torque as a function of engine temperature during cold engine starts so that if an estimate of engine torque is in error, the integrated starter/generator may still successfully start the engine.

Methods and system for estimating engine torque at low temperatures

A method for operating a vehicle that includes a driveline disconnect clutch is described. In one example, the method adjusts torque of an electric machine in response to a estimated torque capacity of the driveline disconnect clutch. The estimated torque capacity of the driveline disconnect clutch is based on a combined inertia of a dual mass flywheel and the driveline disconnect clutch.

Method for operating a vehicle having a driveline disconnect clutch

A vehicle includes a battery, an electric machine, an electrical outlet, and a controller. The electric machine is configured to charge the battery. The electrical outlet is configured to draw power from the battery to power an external device. The controller is programmed to adjust a rate at which the electric machine charges the battery based on a power consumption at the electrical outlet exceeding a threshold and a battery degradation value.

Battery charging system for hybrid or electric vehicle

A vehicle powertrain includes a battery, an electric machine, an electrical circuit, an electrical outlet, and a controller. The electric machine is configured to receive electrical power from the battery to propel the vehicle and to deliver electrical power to the battery to recharge the battery. The electrical circuit is configured to transfer electrical power between the battery and the electric machine. The electrical outlet is configured to deliver power from the electrical circuit to an external device that is connected to the outlet. The controller is programmed to, in response to a first set of conditions that is indicative of the vehicle powertrain overheating or a second set of conditions that is indicative of an inability to charge the battery to a requested charge value, issue a warning of an impending shutdown of the electrical outlet.

Vehicle and method of warning a vehicle operator of an impending shutdown of an electrical outlet on the vehicle

Systems and methods for starting an engine that may be started via an electric machine and a driveline disconnect clutch are described. In one example, the method estimates a maximum motor propulsive torque during engine starting. The maximum motor propulsive torque may be based on an estimated speed that a torque converter impeller speed will be when an engine cranking period ends.

Methods and system to increase available propulsive motor torque during an engine start

A vehicle includes an engine, an electric machine, a battery, accessory devices, an electrical outlet, an inverter, and a controller. The engine and the electric machine are each configured to propel the vehicle. The inverter is configured to deliver power from the battery or the electric machine to the accessory devices or the electrical outlet. The controller is programmed to adjust the power being delivered by the inverter to the electrical outlet based on a discharge power capacity of the battery, a power output capacity of the engine, a power output capacity of the electric machine, and the power being drawn from the inverter via the accessories.
