Claim:
1. A drive control system for a hybrid vehicle, the drive control system comprising: a power split mechanism including a carrier, a sun gear and a ring gear as rotating elements, the power split mechanism being configured to carry out differential action, an engine torque from an engine being transmitted to the carrier; a brake mechanism configured to selectively stop rotation of the carrier; a first motor coupled to one of the sun gear and the ring gear, the first motor being able to generate an electric power; an output member coupled to a second one of the sun gear and the ring gear which is not coupled to the first motor, wherein the output member outputs an output torque; a second motor configured to add a driving torque for propelling the hybrid vehicle to the output torque; and an electronic control unit configured to wherein the motor driven state is a state in which rotation of the carrier is stopped by the brake mechanism, a torque output from the first motor is transmitted to the output member via the power split mechanism, and the second motor is outputting the driving torque.
