Development Of Localised Drive Cycle Under Real Traffic Condition

A drive cycle is a series of data points representing the speed of a vehicle against time. It is widely used for vehicle manufacturers, environmentalists and traffic engineers. The drive cycle of cars plays important roles in fuel consumption. A few years ago, the sales statistic for passenger cars in Malaysia was increased gradually[4]. Drive cycle that represents the real-world driving conditions had been proposed and estimation vehicle fuel consumption was compared with measured results. The purpose of this study is to develop a localised drive cycle in a real traffic condition. Furthermore, the study needs to estimate the fuel consumption of the car. The development of the drive cycle of the vehicle involves three steps: test route selection, data collection, and drive cycle development. Firstly, the selection of the routes also was conducted. The driving cycle was established for the urban area and also for the extra-urban area. The study used the on board measurement method which is by using the application from the smart phone that can help to collect the speed of the vehicle along the road and produce the speed-time profile. The second part of the project was to estimate the fuel consumption of the same car using the data from on board meter of the car compare with the sample calculation that produced by drive cycle. The parameters that can compare are duration, total distance travelled, maximum speed and average speed. The reference data is from the NEDC data. The method is user-friendly. The fuel consumption of the car was produced in term of litre per 100km. The results are in a good fit to the estimated values. The localised drive cycle has their patterns that represent the behavior of the road test. So this drive cycle cannot be comparing with others country
