Abstract

A hybrid vehicle system and control method for enhancing startup flare control includes receiving a start signal for starting an internal combustion engine from a start engine actuator and starting the internal combustion engine, increasing a throttle open angle in response to the start signal to increase engine speed upon starting of the internal combustion engine and, after a desired engine speed is reached, engaging an electric motor with the internal combustion engine to add a drag force on the internal combustion engine thereby rapidly reducing engine speed.

First claim

The invention claimed is:

1. A hybrid vehicle system with enhanced startup flare control, comprising:
an internal combustion engine for providing motive vehicle power;
a start engine actuator for starting the internal combustion engine;
an electric motor selectively coupled to the internal combustion engine for generating electric power from the internal combustion engine;
a throttle control valve disposed within an engine intake associated with the internal combustion engin…
