Abstract:
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, wherein the plurality of sensors detect average speed of vehicles on the plurality of roads, and the plurality of sensors report the traffic information with different cycles according to peak and off-peak periods; in the peak period, a first detection cycle is assigned to the plurality of sensors; in the off-peak period, a second detection cycle, which is longer than the first detection cycle, is assigned to the plurality of sensors; the server comprising: wherein F wherein the processing module further determines whether to planning a new most fuel-efficient path based on the real-time traffic while driving on the most fuel-efficient path; wherein the most fuel-efficient path is kept if the fuel consumption of the new most fuel-efficient path is not 10% better than the most fuel-efficient path.
