Abstract
An object of the present invention is to start an engine while outputting a driving force requested from a driver. According to the present invention, there is provided an engine start control device of a hybrid vehicle including: a start-time target engine rotation speed calculating means; a start-time target engine torque calculating means; a target engine power calculating means that calculates target engine power based on the target engine rotation speed and the target engine torque; an accelerator operation amount detecting means; a vehicle speed detecting means; a target driving power calculating means that calculates target driving power based on the amount of the operation of the accelerator and the vehicle speed; a target electric power calculating means that sets a difference between the target driving power and the target engine power as target electric power; and a motor torque instruction value calculating means that calculates instruction torque values of a plurality of motor generators using a torque balance equation including the target engine torque and an electric power balance equation including the target electric power.
