PROBLEM TO BE SOLVED: To suppress the occurrence of an output fluctuation resulting from the reduction of an output from a motor during vehicle shifting.SOLUTION: A control device is mounted in a hybrid vehicle provided with an engine, a transmission, a motor, and a battery. The control device executes a shifting process for controlling the transmission so as to change a transmission gear ratio and an air-fuel ratio change process for changing an air-fuel ratio of the engine independently of each other, and controls the motor so as to suppress an output fluctuation resulting from each of the shifting process and the air-fuel ratio change process. The control device comprises permission means for permitting, when there is a request of the air-fuel ratio change process for increasing the air-fuel ratio in S102, the air-fuel ratio change process to be implemented in S105 on condition in S104 that electric power that is a combination of electric power necessary to control the motor in order to suppress the output fluctuation resulting from the air-fuel ratio change process and electric power necessary to control the motor in order to suppress the output fluctuation resulting from the shifting process is equal to or lower than a battery upper limit output in S103.SELECTED DRAWING: Figure 2 |
