Abstract:
1. A hybrid vehicle controller used in a hybrid vehicle capable of driving drive wheels using power generated by at least one of an engine and an electric rotating machine and capable of generating electric power from the electric rotating machine using the power generated by the engine, comprising: an operation control unit that controls operations of the engine and the electric rotating machine according to required vehicle power; a power frequency distribution predicting unit that predicts a power frequency distribution of the vehicle in a case where the vehicle travels a route; and an operation condition setting unit that sets an engine operation condition to control an energy balance between generated power and generated electric power of the electric rotating machine in a case where the vehicle travels the route, so as to fall within a preset range according to the power frequency distribution predicted by the power frequency distribution predicting unit, wherein: the operation control unit controls an operation of the engine according to the engine operation condition set by the operation condition setting unit, and the power frequency distribution of the vehicle is expressed by a frequency included in each of a plurality of power bandwidths into which a vehicle power is divided in advance.
