Embodiment Construction

[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In an embodiment to be described below, the internal combustion engine control apparatus according to the present invention is installed in a series HEV (Hybrid Electric Vehicle). The series HEV includes an electric motor, an internal combustion engine, and a generator, and travels using the power of the electric motor driven mainly by a battery as a power source. The internal combustion engine is used only to generate electricity, and the electric power generated by the generator through the power of the internal combustion engine is supplied to the electric motor or stored in the battery.

[0046] The series-type HEV performs "EV running" or "tandem running". In "EV running", the HEV runs with the driving force of the electric motor driven by the power supply from the battery. In addition, in “series travel”, the HEV travels by the driving force of an electric motor d...

Abstract

Th invention relates to control of an internal combustio engine (109), especially when used in a series hybrid vehicle, with a motor (107) delivering drive torque to the wheels. In a constant point operation of the engine (109), engine speed is not linked to accelerator pedal position or vehicle speed. When the driver in this constant point operation steps on the accelerator pedal or the brake pedal, a target engine speed is modified by an offset value. This ensure that the driver gets the same feeling as in a conventional vehicle, i.e. a change in engine speed in response to accelerator or brake pedal actuation. A feeling of incongruity is avoided.

Description

technical field [0001] The present invention relates to an internal combustion engine control device and an internal combustion engine control method for a hybrid vehicle. Background technique [0002] An HEV (Hybrid Electric Vehicle) includes an electric motor and an internal combustion engine, and travels with driving force from the electric motor and / or the internal combustion engine according to the driving conditions of the car. HEVs are broadly classified into two configurations: a series hybrid configuration and a parallel hybrid configuration. A series HEV travels by driving force from an electric motor using a battery as a power source. The internal combustion engine is used only to generate electric power, and the electric power generated by the driving force of the internal combustion engine is stored in a battery or supplied to an electric motor. On the other hand, a parallel type HEV travels with driving force from either or both of an electric motor and an in...
