1. A hybrid vehicle control device for controlling a hybrid vehicle which includes a motor that drives a wheel, a generator that supplies electric power to the motor, and an engine that is configured by an internal combustion engine for driving the generator, comprising:
a control unit that calculates a knock index value indicating a knock degree of the engine at an engine operating point expressed by a relationship between an engine rotation speed and engine torque, and controls the engine rotation speed and the engine torque based on the knock index value,
wherein the control unit sets a target engine rotation speed to be low and target engine torque to be high in a target power generation amount as the knock index value decreases within a range in which the knock index value does not exceed a knock allowable limit value.
