<P>PROBLEM TO BE SOLVED: To provide a series hybrid traction chain for giving extremely advanced acceleration control superior in responsiveness to a driver as well as enabling operation with no electric battery. <P>SOLUTION: The traction chain for a series hybrid vehicle comprises an engine 10 for driving an alternator 11, an electric traction motor 21, an inverter for operating the electric traction motor at a torque set value CC<SB>set</SB>, a driver operated acceleration control device, an actuator 15 to act on the engine, and a control device 3 to which an engine operation model is loaded and to which a program is loaded for creating a pair (R<SB>th/set'</SB>PP<SB>set</SB>) of set values for a speed R<SB>th</SB>of the engine and for a position PP of the actuator 15 from the position of the acceleration control device. The control device 3 controls the position of the actuator in accordance with the set value PP<SB>set</SB>for the position of the actuator and calculates a torque set value CC<SB>set</SB>for the electric traction motor as the function of a deviation between the measured speed R<SB>th</SB>and the set value R<SB>th/set</SB>for the revolution speed of the engine. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
