Abstract
A control apparatus is configured for a hybrid vehicle that can operate highly efficiently in all operating regions. The hybrid vehicle utilizes an internal combustion engine that can be operating using either compression self-ignition combustion or spark ignition combustion. An electronic control unit has a combustion pattern determining section that determines (selects) the combustion method with which to run the internal combustion engine based on the output required by the vehicle. As a result, the internal combustion engine can be operated using the combustion method that is appropriate in view of the required output and unnecessary engine output can be prevented. Thus, a hybrid system that can be operated with high efficiency and at high output in all operating regions can be achieved.
