Abstract
A control apparatus is applied to a hybrid vehicle having a driving apparatus including a power split mechanism which splits torque of an internal combustion engine into a first MG and output portion, and a motor lock mechanism which switches a state of the power split mechanism between a differential state in which the torque of the internal combustion engine splits into the first MG and output portion and a non-differential state in which it is stopped to split the torque. The hybrid vehicle switches a driving mode between a first driving mode in which the power split mechanism is switched to the differential state and a second driving mode in which the power split mechanism is switched to the non-differential state. The control apparatus calculates energy loss of the driving apparatus in each driving mode, and switches the driving mode of the vehicle based on the calculated energy loss.
