If a pregnant woman were to end up in a coma, would there still be childbirth?

Say that the woman is now braindead and 8-9 months pregnant, would the child die in the womb or would there be sort of an "inactive" birth where the body takes control?

Yes. The signal to start labor comes from the fetus. As the lungs (last organ to mature) send out higher and higher levels of surfactant this causes Prostaglandin production to change in the mother and this starts the process of inducing the muscles to contract and deliver the fetus. None of it requires upper motor neuron consciousness.
