Patent ID: 8170747

Claim:
A fleet maintenance method, for maintaining a fleet, wherein the fleet comprises a plurality of vehicles, the fleet maintenance method comprising: clustering the vehicles into a plurality of sub-fleets, and selecting one of the vehicles in each of the sub-fleets as a leader vehicle and the other vehicles as member vehicles; obtaining a position coordinate and a speed of each the vehicle in each of the sub-fleets; converting the position coordinates of the vehicles into a plurality of corresponding linear coordinates; calculating a sub-fleet gravity center of each the sub-fleet, wherein the sub-fleet gravity center of the sub-fleet is calculated according to the corresponding linear coordinates of the vehicles in the sub-fleet; calculating a fleet gravity center of the fleet according to the sub-fleet gravity centers of the sub-fleets; and generating a suggested speed of each the leader vehicle according to a gravity center distance of the leader vehicle, wherein the gravity center distance of the leader vehicle is calculated according to a distance between the leader vehicle and the fleet gravity center.
