Gear Shift Voice Prompt System Based on Optimal Fuel Consumption

Abstract:

In the system, a 51 microcontroller (functions as CPU) collects digital signals transferred by LM358 (functions as voltage comparator) from voltage signals of throttle position sensor; a photoelectric sensor detects vehicle speed while the microcontroller calculates vehicle speed. CPU analyzes and compares these two types of signals and judges whether the optimal fuel consumption for gear shift is reached. If so, CPU will output a playing instruction to a voice chip and remind driver of shifting gears.
