Abstract:
The disclosure describes, in one aspect, a method for changing a direction of a machine that is moving in a first direction. The method includes the step of receiving a signal indicative of an intention to change the direction of the machine to a second direction. The method also includes the step of determining whether a signal indicative of a speed of the machine is greater than a threshold based at least in part on an electric motor parameter. Finally, the method includes the step of applying a braking torque to at least one travel mechanism of the machine in response to a signal indicative of an accelerator pedal position until the speed reaches the threshold.
