基于坡度信号的燃油表算法设计与研究

Design and Research of Fuel Meter Algorithm Based on Slope Signal

燃油信息是驾驶者非常关注的信息,燃油信息显示的精度直接影响用户体验,为提高燃油表显示的稳定性及准确性,在燃油表算法策略中引入坡度信号,目的是解决目前燃油算法无法解决的问题,即:车辆在坡路上长时间行驶以及在坡路上加减油时燃油显示不准确问题,引入坡度信号的同时再考虑燃油传感器阻值及发动机燃油消耗量等参数,设计了燃油表详细算法策略,通过MATLAB/Simulink工具进行仿真,对比分析了此种算法策略与传统策略的优缺点,理论验证了此种算法的可行性与优越性,可以应用于实际车型上。

Fuel information is more concerned for the driver,the accuracy of the fuel information display has a direct influence to the customer experience,in order to improving the stability and accuracy of the fuel gauge,the slop signal in added into the algorithm policy of the fuel gauge,the aim is to solve the problem that the traditional fuel algorithm can not be solved,that is:the fuel gauge will inaccurate display when the car driving on the slope for a long time or change the amount of fuel on the slope,in addition to considering slope signal,the fuel resistance signal and the engine fuel consumption are also been considered at the same time,through the simulation of MATLAB/Simulink tools,compare this method with the traditional method to proving the feasibility and the advantage of this method for the application of the actual vehicles.
