Abstract:
1. A method for operating a power system, comprising: receiving an operator request for a propulsion direction change; directing power into a power source; reducing a supply of fuel to the power source while directing power into the power source; basing a first threshold speed on a speed of the power source produced by directing power into the power source; increasing the supply of fuel to the power source when the speed of the power source falls below the first threshold speed, when the power source speed produced by directing power into the power source exceeds a second threshold speed, setting the first threshold speed above a minimum speed, and when the power source speed produced by directing power into the power source does not exceed the second threshold speed, setting the first threshold speed to the minimum speed, wherein at least one of the preceding steps is performed by a processor.
