Car Networking Micro Letter for Car Fuel Consumption Test of Significance, the Research Present Situation and Main Problems

Abstract

Based on the analysis and summarizing domestic and foreign automobile fuel consumption testing instruments, on the basis of common problems and characteristics of the development level and development trend, according to its adoption of advanced sensor technology, car league two model of the RFID system, car league two highway fuel consumption algorithm (FCIV), microcontroller technology and display technology, the development of intelligent car fuel consumption test instrument to test the fuel consumption, etc. Introduces the current development of fuel consumption detection system at home and abroad. Through to the traditional means of traffic information collection, radio frequency identification (RFID) system is real-time, effective, but there are also acquired data in space and the smell of the discrete case, car league two model of the RFID system, the collection of traffic information to classify the sections for the smallest discrete unit using different fuel consumption test method, developed suitable for different test conditions and test function for fuel testing instrument. Based on high speed road vehicle fuel consumption influence factors to complete various types of vehicle traffic condition modeling micro letter car networking development main problems are put forward. According to the specific situation to modify theoretical model, thus improve fuel consumption detection accuracy. Compare car fuel consumption directly the types and characteristics of the measuring method and indirect measuring method, analysis of displacement method, gravity method and carbon balance method, ultrasonic method and method of fuel injection quantity accumulation detection principle, calculation of mathematical model and its application scope and characteristics. Fuel consumption test system theory is feasible; the fuel consumption test is of great significance.
