Abstract
Provided is a hybrid vehicle control device excellent in quietness while suppressing knocking within an allowable limit. The hybrid vehicle control device of an aspect of the invention is a hybrid vehicle control device that controls a hybrid vehicle including a motor that drives wheels, a generator that supplies electric power to the motor, and an engine configured by an internal combustion engine that drives the generator, and includes a control unit that calculates a knock index value indicating a knock degree of the engine at an engine operating point represented by a relationship between an engine rotational speed and an engine torque, and controls the engine rotational speed and the engine torque based on the knock index value. As the knock index value decreases, the control unit sets the target engine rotation speed to be lower and the target engine torque to be higher in the target power generation amount.
