Heavy-Duty Truck Fuel Economy Test in Actual Road Traffic 973183
To investigate fuel economy of actual road traffic currently experienced in Japan by analyzing the records of sixteen truck drivers. In order to characterize the driving style of each driver, energy consumption relating to road load are integrated from the time series records for each data set and compared with actual fuel economy results.
Through this study, a wide range of driving records are analyzed to determine fuel economy in actual road traffic. The consumed energy (kwh/km), which is the sum of road load defined in this paper was found to be the dominant value in determining fuel economy in actual road traffic.
