DRIVING SOURCE CONTROL DEVICE FOR HYBRID MOTOR VEHICLE AND DRIVING SOURCE CONTROL METHOD FOR HYBRID MOTOR VEHICLE AND HYBRID MOTOR VEHICLE
First Claim
1. A driving source control device for controlling activations of an internal combustion engine and a motor generator of a hybrid motor vehicle that moves by mounting the internal combustion engine that rotates a rotational shaft with a combustion energy and the motor generator that rotates a rotational shaft with an electric energy, the driving source control device for the hybrid motor vehicle comprising:
- a target driving force setting unit for setting a target value of a driving force for driving said motor vehicle;
a motor generator target activation speed acquisition unit for acquiring a target rotational speed of said rotational shaft of said motor generator, based on said target value of said driving force by said target driving force setting unit;
a stored charge amount detection unit for detecting a remaining charge amount of a battery for activating said motor generator;
a driving control unit for controlling activations of said internal combustion engine and said motor generator, based on said target rotational speed of said motor generator acquired by said motor generator target activation speed acquisition unit and said remaining charge amount of said battery detected by said stored charge amount detection unit; and
a command acquisition unit for acquiring an operation command of said motor vehicle;
wherein said driving control unit reduces said target rotational speed of said rotational shaft by said motor generator target activation speed acquisition unit, when said command acquisition unit has acquired a backward moving command and said stored charge amount detection unit has detected said remaining charge amount of said battery that is less than or equal to an internal combustion engine charging requiring setting value set in advance and requiring a charging by said internal combustion engine, at a time of an activation stopping state of said internal combustion engine.

Abstract
To provide a driving source control for a hybrid motor vehicle capable of comfortably driving a motor generator by activating an internal combustion engine only at minimum necessary timings at a time of moving backward. It is a driving source control device 1 for a hybrid motor vehicle that moves by mounting an engine 2 and motor generators 4 and 5, in which a driving control unit 32 reduces a target rotational speed of the first motor generator 4, when a shift position detection unit 47 has acquired a backward moving command and a battery state of charge detection unit 36 has detected that a remaining charge amount SOC of a battery 21 is less than or equal to a setting value, at a time of an activation stopping state of the engine 2.
