A Simplified Method To Form A Passenger/Commercial Vehicle Fuel Economy Test Cycle For Tracks/Autonomous Vehicles 2019-26-0343

Right now, most of the industries are doing real world fuel economy test of their prototypes/mules by deploying them to city, state highways and national highways to declare their FE value. Which involves lot of unexpected problems, large amount of labor and the worst part is the pollution and traffic. With objectives like reducing testing related fuel consumption (reducing fossils consumption), pollution (worldwide concern), cost and project timeline (a benefit for industries), eliminating variations in driving pattern (abnormality during test) and increasing un-launched product confidentiality, a method to create a simplified drive cycle was formed using large sample space of testing parameters. Among already existing drive cycles, this is different because of a simplified mathematics of error and probabilities for method of cycle creation and it has been correlated with the real-world results. This paper reveals a 10-min city drive cycle which was created after studying most of the parameters of vehicle which may affect fuel economy and a whole method, which was devised to form this cycle and then to simplify it enough to drive. Using the derived method some standard cycles for different segments can be created by using already existing data (all industries have plethora of recorded data) and vehicle/engine specifications will be the deciding factor for which cycle needs to be followed.
