  • Patent number: 10315652
    Abstract: A velocity control mechanism is operable to control a vehicle at a maximum forward velocity setting and a maximum rearward velocity setting. The velocity control mechanism includes a processor configured to receive a first signal from an actuator selectively positionable in a velocity control mode in which the vehicle operates at a maximum limited forward velocity less than the maximum forward velocity setting and a maximum limited rearward velocity less than the maximum rearward velocity setting. The first signal represents a desired vehicle forward velocity. The processor also configured to control a velocity of the vehicle in the forward direction based on the first signal and receive a second signal from the actuator. The second signal represents a desired vehicle rearward velocity. The processor further configured to control a velocity of the vehicle in the rearward direction based on the second signal.
