Classification: CPC B  H  Y | IPC B  H

Claim 7:
8. A vehicle operating method, comprising:
via a controller of a vehicle,
anticipating a reduction in driver demand power without receiving a reduction in the driver demand power;
reducing electric power output of a fuel cell to an electric machine in response to the anticipated reduction in a driver demand power before an actual reduction in the driver demand power is received, where the anticipated reduction in the driver demand power includes anticipating that the vehicle is going to be slowed; and
increasing electric power consumed from an electric energy storage device via the electric machine in response to reducing power output of the fuel cell; then
determining no indication to reduce the driver demand power has been received and that the vehicle is still without the reduction in the driver torque demand within a predetermined amount of time after anticipating the reduction driver demand torque; and
in response to there being no indication to reduce the driver demand power and the vehicle still being without the reduction in the driver torque demand within the predetermined amount of time after anticipating the reduction in driver demand power, reducing the electric power output of the fuel cell to the electric machine, and reducing a rate at which the electric power output of the fuel cell is reduced; and then
anticipating an increase in driver demand power via the controller; and
increasing electric power output of the fuel cell to the electric energy storage device in response to anticipating the increase in driver demand power before the increase in driver demand power.
