<P>PROBLEM TO BE SOLVED: To improve overall performance including amenity and environmental performance, in a hybrid vehicle. <P>SOLUTION: A hybrid system 10 calculates torque of an engine 200 from torque reaction of a motor generator MG1. A fuel consumption rate calculating part 100c calculates an instantaneous fuel consumption rate in the engine 200 on the basis of such the calculated engine torque, a fuel injection quantity and an engine speed. An operation line updating part 100d updates an operation line by performing operation point learning processing on the basis of this calculated fuel consumption rate. In this case, the operation line updating part 100d excludes an operation point being a predetermined value or more in an exhaust quantity of NOx from an updating object of the operation line, and updates the operation line in a range of becoming less than the predetermined value in the exhaust quantity of the NOx. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
