<P>PROBLEM TO BE SOLVED: To quickly raise an exhaust temperature even when a battery reaches a full-charged condition. <P>SOLUTION: A load for an engine 2 is made high to carry out warming-up (step S3) by increasing electric power generation torque, when the exhaust temperature is lower than a lower limit value (determination in a step S1 is "No"), for the purpose of activating an exhaust emission control catalyst. The electric power generation torque is limited therein when an SOC reaches an upper limit (determination in a step S2 is "No"), because generated electric power is charged to the battery 9, a gear ratio is changed to an acceleration side (steps S5, S6), and the warming-up is executed thereby while preventing overcharge of the battery 9. <P>COPYRIGHT: (C)2008,JPO&INPIT |
