VEHICULAR CONTROL DEVICE
First Claim
1. A control device for a vehicle to control electrically charging/discharging an electrical storage device, comprising:
- a fuel calculation unit that calculates an amount of fuel consumed that is used to electrically charge said electrical storage device;
a charge calculation unit that calculates electrical energy charged to said electrical storage device;
an evaluation unit that calculates a numerical evaluation relating to an amount of fuel consumed corresponding to an available amount of electric power charged in said electrical storage device, based on results of calculations done by said fuel calculation unit and said charge calculation unit; and
an engine control unit to control an engine, wherein when said numerical evaluation is larger than a threshold value, said engine control unit decreases an engine start threshold value applied to start said engine for each vehicular speed.

Abstract
A control device functions as a vehicular control device to control electrically charging/discharging an electrical storage device. The control device includes a fuel calculation unit which calculates an amount of fuel consumed used to electrically charge the electrical storage device, a charge calculation unit which calculates electrical energy charged to the electrical storage device, and an evaluation unit which calculates a numerical evaluation from a result of a calculation done by the fuel calculation unit and that done by the charge calculation unit for an amount of fuel consumed corresponding to an amount of electric power charged in the electrical storage device availably.
