Analysis of test results using an automatic start-stop system in vehicle driving modes

Abstract

In this paper, the energy efficiency of automobiles through the automatic start-stop system as a part of the intelligent transport systems was determined by the research method. In the research method, the vehicle's driving mode was analyzed according to the NEDC (New European Driving Cycle) standard. The M1 category Chevrolet Nexia used the method of measuring fuel consumption by volume in the drive cycle at the auto polygon. In this method, the capabilities of the car's design and electronic control unit were used to determine fuel consumption and vehicle speed. The data were obtained via OBD-II from onboard the vehicle through the Scanmatic diagnostic device. The diagram forms were generated using computer technology. The fuel consumption of the car is 8.0 liters per 100 km in the technical parameters. The car consumed 7.5 liters of fuel while using automatic start-stop technology in the auto polygon. The calculation method showed us the system saved 6.25% of the fuel and emitted 6.25% less exhaust gases to the environment.
