  • Publication number: 20250121739
    Abstract: Methods and systems for managing power of a hybrid vehicle that includes a fuel cell and a traction battery are described. In one example, cooling of the battery and fuel cell may be adjusted preemptively before the hybrid vehicle reaches high load conditions to extend fuel cell durability over its life span, meanwhile the hybrid vehicle may meet driver demand for a longer period of time while operating at the high load and high ambient temperature conditions.

  • Publication number: 20240204219
    Abstract: A multiple fuel cell thermal management system controls a proportional mixing valve, heat exchanger bypass valves, fan speeds, and pump speeds of respective coolant circuits and associated fuel-cell stacks to operate the stacks independently or in combination. When vehicle wheel loads are low or in applications with standby fuel-cell stacks, selected stacks are turned off. During moderate loads or high ambient temperature, the working fuel cell cooling system(s) operates in parasitic load reduction mode, using the non-working cooling circuit(s) as a heat sink running the associated pump at low speed and throttling the proportional mixing valve such that efficient cooling is accomplished in the running circuit with less fan power required than if the non-working circuit is completely shut down. A heat exchanger bypass valve and fan speed are controlled to provide a target stack inlet temperature. Pump speed is controlled responsive to a stack inlet/outlet temperature difference.

  • Patent number: 11654875
    Abstract: A vehicle includes an electric machine, friction brakes, a drivetrain, and a controller. The electric machine is configured to recharge a battery during regenerative braking. The friction brakes are configured to apply torque to wheels of the vehicle to slow the vehicle. The controller is programmed to, in response to and during an anti-locking braking event, generate a signal indicative of a total torque demand to brake the vehicle based on a difference between a desired wheel slip ratio and an actual wheel slip ratio, adjust a regenerative braking torque based on a product of the signal and a regenerative braking weighting coefficient, adjust a friction braking torque based on a product of the signal and a friction braking weighting coefficient, and further adjust the regenerative braking torque based on a closed-loop control of an estimated regenerative braking torque feedback.

  • Patent number: 11548372
    Abstract: Methods and system for operating a vehicle cooling system are described. In one example, the vehicle cooling system cools a heat generating device via a fan and pump. A speed of the fan is commanded by a feedback controller with possible neural network predictive control to track a variable temperature reference that is based on thermal load estimation. A disturbance observer may be applied to observe thermal load and an observer-based observer may be used to generate the temperature reference so that the power consumption of a fan is minimized.

  • Patent number: 11225244
    Abstract: A system and method is disclosed for engine starting and transmission shifting where a controller may be operable to decrease a torque of a motor and operate a starter-generator (ISG) to start an engine responsive to a command to shift the transmission and start the engine. The controller may disengage a second clutch and subsequently shift the transmission to a target gear ratio speed responsive to the torque of the motor achieving zero. The controller may increase respective torques of the motor, ISG, and engine to drive a speed of the motor, ISG, and engine toward a target speed defined by the target gear speed responsive to completion of the shift. The controller may engage the second clutch responsive to the speed of the motor achieving the target speed and engage a disconnect clutch responsive to the respective speeds of the ISG and engine achieving the target speed.
