An apparatus and method of driving control of a hybrid vehicle in the invention divides a route into a plurality of section on the basis of a point at which start of the vehicle is predicted and a point at which stop of the vehicle is predicted or a start point of a regeneration section in which the motor continuously performs a regenerating operation for a predetermined time or longer as a border; estimates a vehicle speed pattern for each of the plurality of sections on the basis of a road condition and a driving history; and sets an operating schedule of the engine and the motor so as to minimize the fuel consumption of the engine to the destination on the basis of the vehicle speed pattern and fuel consumption characteristics of the engine.

[ What is claimed is:] [1.]1. A driving control apparatus of a hybrid vehicle having a battery, a motor, and an engine, in which power is supplied from the battery to the motor, power generated by driving the motor by the engine and regenerated power of the motor are supplied to the battery, and the hybrid vehicle is driven by at least one of the motor and the engine, comprising:a route retrieving unit retrieving a route to a destination;a road condition detecting unit detecting a road condition of the route;a route dividing unit dividing the route into a plurality of sections on the basis of a point at which start of the hybrid vehicle is predicted and a point at which stop of the hybrid vehicle is predicted on the basis of the road condition;a driving history recording unit recording driving history;a vehicle speed pattern estimating unit estimating a vehicle speed pattern for each of the plurality of sections on the basis of the road condition and the driving history; anda schedule setting unit setting an operating schedule of the engine and the motor so as to minimize the fuel consumption of the engine to the destination on the basis of the vehicle speed pattern and fuel consumption characteristics of the engine,wherein among the plurality of sections, the schedule setting unit sets a section, in which operating efficiency of the engine is low, as a driving section in which the hybrid vehicle is driven by the motor, when the fuel consumption of the engine in the case that the hybrid vehicle is driven by the motor in the section in which the operating efficiency of the engine is low and the engine drives the motor to generate the power in another section is smaller than the fuel consumption of the engine in the case that the hybrid vehicle is driven by the engine in the section in which the operating efficiency of the engine is low.
