1. A damping control system comprising:
a damping chamber connected to one of (a) a body of a vehicle and (b) a wheel of the vehicle;
a piston that is slidably disposed within the damping chamber and that includes:
a piston rod that is connected to the other one of (a) the body of the vehicle and (b) the wheel of the vehicle; and
a plunger that is connected to the piston rod and that divides the damping chamber into a first chamber and a second chamber;
a first valve that regulates hydraulic fluid flow out of the first chamber; and
a valve control module configured to selectively close the first valve when a position of the plunger is between (a) a first reference position within the first chamber and (b) a first end stop of the damping chamber that defines a boundary of the first chamber.
