Abstract: A vehicle includes a drive wheel, an engine, an accelerator pedal, a torque converter, a clutch, and a controller. The drive wheel is configured to propel the vehicle. The engine is configured to generate power and to deliver power to the drive wheel to accelerate the vehicle. The accelerator pedal is configured to generate an acceleration request based on a pedal position. The torque converter is disposed between the engine and the drive wheel. The clutch is disposed between the engine and the drive wheel and is configured to bypass the torque converter. The controller is programmed to, in response to depressing the accelerator pedal to a position that corresponds with accelerating the vehicle at a desired magnitude, adjust the torque of the engine to accelerate the vehicle at the desired magnitude, regardless of the state of the clutch.

Abstract: Methods and systems are provided for performing expansion combustion in an engine of a start-stop vehicle. In one example, a method may include, responsive to receiving an auto-start request to restart an engine from an auto-stop, determining a fuel mass to inject into a cylinder for an expansion combustion event based on a duration of the auto-stop, and actuating a spark plug of the cylinder after injecting the determined fuel mass to perform the expansion combustion event. In this way, an air-fuel ratio of the expansion combustion event may be more accurately controlled, resulting in more robust expansion combustion engine restarts.

Abstract: Methods and systems are provided for coordinating engine and motor torque in a hybrid vehicle system. The systems and methods use an engine torque command to obtain a motor torque command, and adjust the engine torque command based on an estimate of a time delay between commanded and actual motor torque prior to the engine command being sent to an engine controller. In this way, crankshaft torque accuracy may be improved.

Abstract: A vehicle includes controller programmed to receive a driver-demanded wheel torque command and calculate a shaped wheel torque command based on the driver-demanded wheel torque command. The controller is further programmed to, in response to the driver-demanded wheel torque command changing from a first magnitude that is greater than an estimated wheel torque at a last time step to a second magnitude that is less than the estimated wheel torque at a current time step, set the shaped wheel torque to a minimum of a magnitude of the shaped wheel torque at the last time step and an estimated wheel torque at the current time step. The controller is also programmed to command the first and second actuators to produce the shaped wheel torque.

Abstract: A method for operating a vehicle that may be automatically stopped and started is described. In one example, the method includes supply electrical current to a starter motor independently from supplying electrical current to a starter solenoid. In addition, the method includes adjusting and amount of electrical current that is delivered to the starter motor in response to a level of urgency of an automatic engine start.

Abstract: A method for stopping an engine within a desired crankshaft angular range is disclosed. In one example, the method may take no control actions if it is determined that the engine will stop within the desired crankshaft angular range. However, if it is determined that the engine may stop outside of the desired crankshaft angular range, expansion combustion may be initiated in a cylinder so that the engine stops in a desired crankshaft angular range.

Abstract: Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, and a transmission, where the transmission is downstream of the engine, and where the electric machine is downstream of the transmission. In one example, while the vehicle is being propelled solely via the electric machine, one or more gears of the transmission may be pre-engaged or selected, to prepare the driveline for an engine start event. In this way, driveline torque disturbance and delays in torque requests may be reduced or avoided upon a request for an engine start event.
