A drive apparatus of a hybrid vehicle including an internal combustion engine, a first motor-generator, a second motor-generator, a planetary gear mechanism, a speed change mechanism and an electronic control unit. The speed change mechanism includes a first engagement mechanism and a second engagement mechanism. A microprocessor of the electronic control unit is configured to perform controlling the speed change mechanism so as to disengage the first engagement mechanism and engage the second engagement mechanism before a driving force increase instruction is output during traveling in an EV reverse mode and so as to engage the first engagement mechanism and disengage the second engagement mechanism when it is determined that the driving force increase instruction is output during traveling in the EV reverse mode.
