an axle assembly coupled to the chassis and supporting a plurality of wheels;
an actuator coupled to the chassis and the axle assembly, the actuator configured to transition the axle assembly between a raised position and a lowered position;
a parking brake configured to selectively prevent rotation of the plurality of wheels;
a controller comprising a processor and a memory, the controller configured to:
determine a vehicle state based on data representing at least one of a vehicle load, a vehicle location, and a vehicle operating condition;
operate the actuator to transition the axle assembly between the raised position and the lowered position based on the vehicle state;
determine that the axle assembly is in the lowered position; and
actuate the parking brake into a disengaged position to permit rotation of the plurality of wheels responsive to the determination that the axle assembly is in the lowered position.
