- The goal of this study was to evaluate the effect of driving cycle and various driving habits on fuel efficiency. The track tests were conducted based on the SAE J 1321 Fuel Consumption Test Procedure-Type II, with various vehicles in various loading states. Several duty cycles were replicated on the track, such as a local delivery cycle developed based on the operational data, urban school bus cycle, and an aggressive stop-and-go cycle. Drivers were allowed to accelerate and decelerate according to their assigned driving techniques. Therefore, the drivers using moderate driving techniques followed the drive cycle, while the drivers using aggressive and eco-friendly techniques used the speed steps as targets, with varying acceleration and deceleration profiles. For some tests, the drivers noted that for the tests with loaded vehicles, it was difficult to simulate the aggressive technique, the acceleration pedal was not responding well, and there were delays in engaging the gears. The engine and transmission seemed to be protected against aggressive driver behavior. The fuel savings obtained with normal and eco-friendly driving techniques varied depending on the duty cycle, however significant savings were observed for both loaded and unloaded vehicles. Driving technique is a major factor that influences fuel economy, and technical considerations must be accompanied by training in eco-friendly driving, especially for aggressive drivers, and must be incorporated into a process of continuous improvement and monitoring of driver performance.
