Abstract

The present application relates to a control device of a hybrid vehicle and a control method of a hybrid vehicle. The control device of the hybrid vehicle executes engine start processing when a condition for execution of start of an engine is satisfied. The engine start processing includes first start processing of driving a motor generator in order to start the engine, and second start processing executed in the case where the first start processing fails. The second start processing includes driving the motor generator in order to start the engine after supply of electric power to the motor generator is interrupted. The control device executes counting processing of counting a number of times that the second start processing is executed in the case where the first start processing fails. The control device prohibits idle stop of the engine even when the second start processing succeeds in the case where the number of times is equal to or greater than a determination threshold.
