The Control Strategy to Realize the Function of Gear Shift Indicator

Wang Yeqing,Huang Liusheng,Ren Qiang

Abstract:The paper discusses the device and principle of one SUV model gear shift indicator function realization, combined with the engine characteristics, gearbox ratio and vehicle parameters, through calculation to determine the best shift line, in order to control precision, at the same time for slope correction and altitude correction.  The study is to timely remind the driver to shift or keep the current gear, ensure that the engine works in the best economic zone, let the driver develop good driving habits, so as to achieve the purpose of reducing fuel consumption.

Key words:gear shift indicator, engine characteristics, gearbox speed ratio, slope correction, altitude correction
