There are many vehicle types such as different gear ratios and different bodies in heavy-duty conventional vehicle (HD-CV) category. Therefore, in Japan, following simulation method is used for evaluating fuel economy and exhaust emissions of HD-CVs: 1) Engine speed and torque is calculated with dedicated program, 2) After that, fuel economy is calculated by adding fuel consumption map, and exhaust emissions are measured with engine unit on engine dynamometer. Concerning the test method for heavy-duty hybrid electric vehicles (HD-HEVs), must be evaluated as a vehicle system because they consist of not only an engine but also other components such as a motor generator and a rechargeable energy storage system featuring regenerative braking, and operating condition of these components are controlled by hybrid electronic control unit. However, chassis dynamometer testing method for HD-HEVs takes thousands of man-hours and expensive. Therefore, a hardware-in-the-loop simulator (HILS) method is developed as technical guidelines in 2007. Currently, the HILS method is being discussed for developing national technical regulations and globally-harmonized technical regulations. Therefore, all information of the HEV model which has currently non-disclosure part must be fully disclosed. This open-source HEV model corresponding to parallel HEVs equipped with an automated manual transmission or a manual transmission.
