Control apparatus for internal combustion engine
First Claim
1. A control apparatus for an internal combustion engine installed on a vehicle, comprising:
- a rotating electrical machine for both electric operation and electric power generation that is connected to said internal combustion engine;
a control circuit that controls at least one of a field current and an armature current of said rotating electrical machine;
a rotational speed detection part that detects the individual rotational speeds of said internal combustion engine and said rotating electrical machine;
a power supply system connected to said rotating electrical machine;
an electric power detection part that detects an amount of electric power of said power supply system; and
a rotational fluctuation suppression section that suppresses the rotational fluctuation of said internal combustion engine;
wherein said rotational fluctuation suppression section controls an amount of electric power generation and generated torque from said rotating electrical machine in accordance with an electric power load of said vehicle, the amount of electric power of said power supply system, and the rotational speed of said rotating electrical machine.

Abstract
A control apparatus for an internal combustion engine can effectively suppress the rotational fluctuation of the engine by properly controlling the operating state of a rotating electrical machine without applying an excessive load to a power supply system connected to the rotating electrical machine. The rotating electrical machine is used for both electric operation and electric power generation, and is connected to the engine. A control circuit controls at least one of a field current and an armature current of the rotating electrical machine. A power supply system is connected to the rotating electrical machine. A rotational fluctuation suppression section (ECU) suppresses the rotational fluctuation of the engine by controlling an amount of electric power and generated torque of the rotating electrical machine in accordance with an electric power load of the vehicle, an amount of electric power of the power supply system, and the rotational speed of the rotating electrical machine.
