[Object]To provide a hybrid vehicle power generation system capable of generating electric power enabling a continuous travel by a generator even when communication abnormality with a control device occurs and preventing an occurrence of a welding of a disconnected contactor provided in a high-voltage current path or a voltage surge of the high-voltage current path.[Solution]A hybrid vehicle 1 includes a high-voltage current path 20 connected to a generator 13 and receiving high-voltage electric power generated by the generator 13, a low-voltage current path 21 connected to the generator 13 and supplying low-voltage electric power having a voltage lower than the high-voltage electric power to the generator 13, a contactor 14A switched by a control device 19 to a closed state of connecting the high-voltage current path 20 or an open state of disconnecting the high-voltage current path 20, and a relay 16 switched by the control device 19 to a closed state of connecting the low-voltage current path 21 or an open state of disconnecting the low-voltage current path 21. The generator 13 stops autonomous generation of electric power when the relay 16 is switched to the open state to disconnect the low-voltage current path 21 during the autonomous generation of electric power. The control device 19 switches the relay 16 from the closed state to the open state before the contactor 14A is switched from a closed state to an open state when switching the contactor 14A from the closed state to the open state.
