Fuel-Saving Path Planning Navigation System and Fuel-Saving Path Planning Method Thereof
First Claim
1. A fuel-saving path planning navigation system, comprising:
- a plurality of sensors monitoring a plurality of roads respectively and periodically reporting traffic information to a server;
the server comprising;
a storing module storing the traffic information as history information;
a processing module estimating how many vehicles on a road based upon the history information, calculating fuel consumption of each possible planned path including current fuel consumption based on real-time traffic and future fuel consumption based on the historical information, and planning a most fuel-efficient path based on a following relation;
Fx=ρ
×
Fx,N+(1−
ρ
)×
Fx,H;
wherein Fx is a fuel consumption of a road x, ρ
is a real number between 0 and 1, Fx,N is a real time fuel consumption of the road x, and Fx, His a fuel consumption from the history information of the road x.

Abstract
A fuel-saving path planning navigation system and a fuel-saving path planning method thereof. A plurality of sensors monitors a plurality of roads respectively and periodically report traffic information to a server. The server comprises a storing module and a processing module. The storing module stores the traffic information as history information. The processing module estimates how many vehicles on a road based upon the history information, calculates fuel consumption of each possible planned path including current fuel consumption based on real-time traffic and future fuel consumption based on the historical information, and plans a most fuel-efficient path. Also, the processing module recalculates fuel consumption of remaining path and changes the remaining path while fuel cost of a new path better 10% than the remaining path.
