From the use of while loops, the AEV could incorporate “controlled coasting”. This means the AEV could coast to a slower speed then accurately stop a specific point with a small power brake. This method optimizes energy efficiency and accuracy. Energy efficiency can also be found in the power brake. Only one motor used in a short burst is needed to stop the AEV. Since the motors were positioned in opposite directions, the more efficient pull direction of the motor (for braking) could be incorporated when the AEV moved in either direction. The coasting portion of the brake also helps to decelerate the AEV in a safe, comfortable manner for the passengers, which makes the power brake less harsh. For the final brake both motors are used to safely stop the AEV and caboose within the unloading dock.
