1. A cruise control system for a work vehicle, the cruise control system comprising:
one or more vehicle interlocks, each of the one or more vehicle interlocks configured to monitor a vehicle system status;
an implement interface configured to monitor header load information; and
a cruise control controller configured to monitor the one or more vehicle interlocks;
wherein when at least one of the one or more vehicle interlocks is triggered and cruise control is not activated, the cruise control controller prevents cruise control activation;
wherein when at least one of the one or more vehicle interlocks is triggered and cruise control is activated, the cruise control controller notifies an operator of the at least one triggered vehicle interlock and deactivates cruise control; and
wherein when none of the one or more vehicle interlocks is triggered, the cruise control controller activates cruise control, predicts changes to a vehicle ground speed based on the header load information, and takes preventative action based on the predicted changes to the vehicle ground speed to maintain the vehicle ground speed at a vehicle cruise speed.
