There is provided a controller for a hybrid vehicle which can improve fuel consumption performance and driveability. A controller for a hybrid vehicle which can run in an EV drive mode in which an electric motor 101 is driven by electric power of a battery 113 only and a series drive mode in which the electric motor 101 is driven by electric power generated by a generator 107 using power of an engine 109 includes a demanded driving force calculation unit for calculating a demanded driving force for the electric motor 101 based on vehicle speed and accelerator pedal opening, a demanded electric power calculation unit for calculating a demanded electric power demanded of the electric motor 101 based on the demanded driving force and a revolution speed of the electric motor 101, an available uppermost outputting value setting unit for setting an available uppermost outputting value for the battery 113 based on the conditions of the battery 103, and an engine starting determination unit for determining on the starting of the engine 109 based on the demanded electric power demanded of the electric motor 101. The engine starting determination unit starts the engine 109 so that the vehicle runs in the series drive mode when the demanded electric power demanded of the electric motor 101 exceeds the available uppermost outputting value. |
