Title:
SYSTEM AND METHOD FOR EVALUATING FUEL SAVING OPERATION
Document Type and Number:
WIPO Patent Application WO/2003/095821
Kind Code:
A1
Abstract:
At the time of detecting and recording vehicle data of items for evaluating fuel saving operation (e.g. vehicle speed, engine r.p.m. at the time of shift up, idle time, and the like), any one of predetermined first through Nth traveling conditions (e.g. high speed traveling, general road traveling, idle operation) to which current traveling conditions belongs is determined and the vehicle data is recorded for each traveling condition. Fuel consumption is also recorded for each traveling condition. Marks are then given to the vehicle data of each traveling condition with reference to each evaluation criterion and then the marks are corrected by the fuel consumption ratio of each traveling condition. Since the marks are corrected while taking account of the traveling conditions, fuel saving operation can be evaluated more appropriately.
