The fuel-saving driving evaluation apparatus and fuel-saving driving evaluation method of the dump truck

摘要

PROBLEM TO BE SOLVED: To evaluate the implementation situation of a fuel saving driving quantitatively and in a unified manner, corresponding to a car type or driving condition, using ecological drive on-vehicle equipment easy in the replacement to the other vehicle and having a simple structure.;SOLUTION: A operation condition and a loading condition are analyzed based on at least vehicle speed, engine rotation speed and vehicle specification and an ideal fuel saving driving model comprising an optimum shift up method, an optimum acceleration method, an optimum deceleration method and an optimum economical speed is formed in each moving distance of one interval from the starting up to the stopping using the analyzed result of the operation condition and loading condition. An evaluation object fuel consumption is calculated based on an engine fuel consumption map and the analyzed operation condition and loading condition, the ideal fuel consumption is calculated based on the ideal fuel saving driving model and the analyzed operation condition and loading condition, and the evaluation object fuel consumption and the ideal fuel consumption are compared to each other to calculate a fuel saving driving achievement rate.;COPYRIGHT: (C)2013,JPO&INPIT
