SYSTÈME ET PROCÉDÉ DE CONFIRMATION D'ENGRENAGE D'ENTRAÎNEMENT ÉCONOMIQUE POUR VÉHICULE ENTRAÎNÉ PAR UN MOTEUR

摘要

A system and method of selecting optimum gear of automobile is provided. The system includes a data processor; a running vehicle data collection module; an output module; and a memory. The memory is stored with universal characteristic curve of an engine, gear ratios of a gearbox, speed reduction ratios, and a tire radius. The running vehicle data collection module collects and sends a current vehicle speed, revolutions of the engine, and an output torque of the engine to the data processor. The data processor processes the universal characteristic curve of the engine, the gear ratios of the gearbox, the speed reduction ratios, and the tire radius to determine a current gear and an optimum gear. The data processor outputs the optimum gear to the output module if the current gear is not the optimum gear. The system can select optimum gear in real time and lower fuel consumption.
