“…Using the same method as used for the road energy consumption calculation, the total tractive energy and braking energy of the entire driving cycles could be calculated by equations (16) and (17). However, during the chassis dynamometer test the instantaneous hub torque at each side of the rear wheels was measured as shown in Fig.…”

“…This means that the resistant forces the vehicle experiences on the chassis dynamometer are only a little smaller than those on the road. The combination of vehicle driveline drag, chassis dynamometer system loss and rolling resistance can be represented as a second-order equation of vehicle speed [9,[17][18][19], and data reduction results are presented in Table 3, where the same terms are used as in the road coast-down analysis.…”

In order to acquire vehicle emissions and fuel economy by driving a vehicle on a chassis dynamometer, it is imperative that the chassis dynamometer should exactly simulate the road experience of the vehicle. In this paper, the modelling of a heavy-duty vehicle energy consumption both on the road and on a chassis dynamometer was developed and implemented by using two driving cycles. Road coast-down tests of a vehicle were conducted to obtain a road load equation of the vehicle. Its companion chassis dynamometer coast-down tests were aimed to estimate the characteristics of the dynamometer-vehicle system. Power absorber settings were achieved that duplicate the vehicle road load in the dynamometer testing. Comparing the measured energy of the vehicle between driving cycles on the chassis dynamometer and the calculated energy on the road, it is shown that the West Virginia University (WVU) transportable heavy-duty chassis dynamometer is successful in simulating the vehicle road load conditions when conducting emissions testing.
