Abstract: Systems and methods for operating a driveline of a hybrid vehicle are presented. In one example, the systems and methods adjust a driveline disconnect clutch boost time duration or magnitude responsive to a pressure error and a time delay error. A driveline disconnect clutch may be operated via supplying a pressure to the driveline disconnect clutch that includes the adjusted boost time duration or magnitude.

Abstract: Methods and systems are provided for adjusting driver demand wheel torque of a vehicle. The driver demand wheel torque may be adjusted as a function of a minimum wheel torque. The minimum wheel torque may be determined according to a plurality of torques that may be evaluated in three different phases.

Abstract: A vehicle includes an engine, an electric machine, a disconnect clutch, and a controller. The engine and the electric machine are each configured to generate power. The disconnect clutch is disposed between the engine and the electric machine. The controller is programmed to, in response to a command to start the engine, close the disconnect clutch to transfer power from the electric machine to the engine. The controller is further programmed to control the torque of the disconnect clutch via increasing a pressure applied to the disconnect clutch based on a first-order model of the pressure applied to the disconnect clutch. The controller is further programmed to adjust the model based on a difference between an expected pressure to the disconnect clutch and a measured pressure of the disconnect clutch during a time period prior to transferring torque through the disconnect clutch.

Abstract: A vehicle operating method comprising generating a base torque reserve for an engine based on a position of an accelerator pedal and a position rate of change of the accelerator pedal, where the base torque reserve is an air reserve of the engine generated by the engine. The base torque reserve may further be generated based on one or more of a drive mode, a vehicle altitude, a battery state of charge (SOC), and a transmission gear, in at least one example.

Abstract: Systems and methods for operating a driveline disconnect clutch of a hybrid vehicle are presented. In one example, torque capacity of a driveline disconnect is adjusted in response to a change in commanded line pressure. The torque capacity of the driveline disconnect clutch may be adjusted in according to a maximum transmission line pressure.

Abstract: A vehicle includes a fuel cell system (FCS), a traction battery, and a controller. The controller controls the FCS to output a constant amount of power throughout a vehicle trip. Responsive to a demanded power greater than the constant amount, the controller controls the traction battery to output an amount of power commensurate with a difference between the demanded power and the constant amount.

Abstract: A hybrid vehicle includes an engine, an electric machine, and a clutch configured to selectively couple the engine to the electric machine. A controller is programmed to command a torque to the electric machine based on a clutch model that includes a learned time constant previously selected using a family of candidate time constants based on a comparison of the family to measured pressure data of a previous engagement of the clutch.

Abstract: Systems and methods for improving operation of a vehicle are presented. In one example, a controller may respond to a presence or absence of a prediction of an increase in vehicle speed during a look ahead window. The controller may inhibit or allow automatic engine stopping in response to the presence or absence of the prediction of the increase in vehicle speed during the look ahead window.

Abstract: 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.
