A drive control system is for a hybrid vehicle. The drive control system includes a power split mechanism (4), a brake mechanism (11), a first motor (2), an output member (15), a second motor (3) and an electronic control unit (24). The electronic control unit (24) is configured to obtain a temperature of the power split mechanism based on a first time that is a duration of a motor driven state, allow the motor driven state when the obtained temperature obtained by the electronic control unit (24) is lower than a predetermined upper limit temperature, and inhibit the motor driven state when the obtained temperature is higher than or equal to the upper limit temperature.
