Abstract: A fuel cell electric vehicle is powered by a fuel cell that converts hydrogen gas into electricity to power the vehicle's electric motor. The fuel cell drivetrain includes the fuel cell, traction battery, vehicle controller, and other components. The vehicle controller, also known as an electronic control unit, manages and controls various functions of the vehicle, such as the fuel cell system, engine, and traction battery. It makes decisions based on data from sensors and inputs and optimizes fuel efficiency.

Abstract: A vehicle includes a fuel cell, an inlet valve, a purge valve, and a controller. The fuel cell has an anode side configured to receive hydrogen. The inlet valve is configured to open to deliver the hydrogen to the anode side. The purge valve is configured to open to purge water and nitrogen from the anode side. The controller is programmed to, operate the inlet valve to inject hydrogen into the anode side via opening the inlet valve followed by closing the inlet valve. The controller is further programmed to, in response to a concentration of the hydrogen in the anode side being less than threshold, open the purge valve to purge water and nitrogen from the anode side.

Abstract: Systems and methods for starting an engine of a hybrid vehicle are described. In one example, the method starts an engine according to vehicle conditions that are within a range that is defined by one or more thresholds. The thresholds may be adjusted based on a history of individual driving patterns.

Abstract: A vehicle includes a fuel cell having an air inlet port and an air outlet port and an air supply system having a compressor connected in fluid communication with the inlet port and a throttle valve connected in fluid communication with the outlet port. A controller is programmed to change a position of the throttle valve based on a target mass air flow, a measured mass air flow, a measured pressure, and the position of the throttle valve.

Abstract: Systems and methods for operating a vehicle that includes an engine and an electric machine are described. In one example, electric machine torque is adjusted according to a wheel torque in a wheel torque creep mode where an engine provides torque to vehicle wheels. Operating the electric machine in this way may allow the electric machine to emulate wheel creep torque that is generated via an engine.

Abstract: A vehicle includes an engine, a motor, and a controller. The engine and motor are each configured to deliver torque to a torque converter impeller. The controller is programmed to, responsive to a demanded impeller torque exceeding an upper motor torque threshold while the motor alone is delivering torque to the impeller, increase motor torque to a value that is less than the threshold and that depends on a torque converter bypass clutch torque capacity and a torque converter turbine speed.

Abstract: Methods and systems are provided for controlling yaw of a vehicle while maintaining vehicle speed. In one example, equal and opposite vectoring torques are applied to first and second wheels along with a propulsion torque so that a vehicle yaw moment may be induced without accelerating or decelerating the vehicle.

Abstract: Methods and systems are provided for improving engine restart operations occurring during a transmission shift in a hybrid vehicle. Engine speed is controller during cranking and run-up to approach a transmission input shaft speed that is based on the future gear of the transmission shift. Engine speed is controlled via adjustments to spark, throttle, and/or fuel, to expedite engine speed reaching the synchronous speed.
