To efficiently operate a hybrid vehicle, in an internal combustion engine control device and method of the hybrid vehicle, for controlling operation state of an internal combustion engine in the hybrid vehicle having the internal combustion engine and a motor generator as a motive power source.
A hybrid system 10 calculates the torque of an engine 200 from torque reaction of the 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. An operation point setting part 100f normally sets an operation point on this operation line, and sets the operation point of the engine 200 to an operation point for maximizing system efficiency including efficiency of a driving system when a request driving force exists in an area for generating the energy recirculation on a control map 31 for expressing the relationship between a vehicle speed and the request driving force.
