PROBLEM TO BE SOLVED: To solve a problem associated with increasing a fuel injection amount when an internal combustion engine is cold-started in a hybrid vehicle, the problem in which, in the state of an output upper limit value of a secondary battery being high, the revolution speed of the engine becomes relatively high, being unable to secure injection time, and therefore it is unable to increase the injection amount sufficiently.SOLUTION: When an internal combustion engine is cold-started (S100), a fuel injection amount is increased (S102). In the case of an output upper limit value of a secondary battery being higher than a given value (S104), fuel injection pressure is increased (S106). With high injection pressure, it is possible to inject large amount of fuel in a short period of time and respond to an increased injection amount.SELECTED DRAWING: Figure 2 |
