Drive control system for a hybrid vehicle

A 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 adapted to: obtain a first time which is a duration of a motor-driven state, and / or a second time which is a duration of a state in which driven the engine condition terminated, estimate a temperature of the power split mechanism (4) based on the first time and / or the second time, and to allow the motor driven state in accordance with a temperature of the power split mechanism (4), the first time or the second time or block.
