Hybrid Vehicle Controller
First Claim
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 of 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, the power frequency distribution of the vehicle being expressed by a frequency included in each of a plurality of power bandwidths into which a vehicle power is divided in advance; 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.

Abstract
A power frequency distribution predicting unit predicts the power frequency distribution of a vehicle in a case where the vehicle travels a route with reference to the history of the vehicle power Pv when the vehicle traveled the route in the past. An operation condition setting unit sets the range of the required vehicle power Pv0 to operate the engine as an engine operation condition for controlling the energy balance between generated power and generated electric power of an electric rotating machine in a case where the vehicle travels the route to be at a preset value according to the power frequency distribution predicted by the power frequency distribution predicting unit. An operation control unit controls the operation of the engine according to the range of the required vehicle power Pv0 to operate the engine set by the operation condition setting unit.
