چکیده
This paper deals with an investigation of different control strategies for a series hybrid electric vehicle (SHEV). Another discussed issue is the application of a free-piston generator. By replacing a conventional combustion engine with a free-piston generator it is possible to increase the total efficiency of the system. The object of investigation is a 12-ton truck, mainly used in urban areas. The drive system has been built up and simulated in a MATLAB Simulink environment. It follows from the investigation that the application of a free-piston engine in a SEHV can increase the efficiency by 25 percent compared to the conventional engine. 2. MODEL The object for this study is a 12-ton distribution truck with the data presented in table 1 TABLE 1 VEHICLE DATA FOR THE 12-TON TRUCK Vehicle data Curb weight 5.5 ton
