1. A system for controlling a vehicle, the system comprising:
the vehicle;
at least one forward-looking sensor disposed within the vehicle;
a positioning system disposed within the vehicle;
a processor disposed within the vehicle and configured to:
during a deceleration of the vehicle, determine, based on inputs from the at least one forward-looking sensor or the positioning system,
whether it is predicted that a driver of the vehicle will stop decelerating the vehicle and will instead accelerate the vehicle; and
if it is predicted that the driver of the vehicle will stop decelerating the vehicle and will instead accelerate the vehicle, inhibit a downshifting of a transmission of the vehicle,
wherein determining whether it is predicted that the driver of the vehicle will stop decelerating the vehicle and will instead accelerate the vehicle involves determining whether, for greater than a threshold duration, a torque on a brake of the vehicle exceeds a torque threshold and a rate of change of the torque on the brake is greater than zero.
