Abstract:
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 engine, the throttle control valve arranged such that increasing an open angle of the throttle control valve increases an engine speed of the internal combustion engine; and at least one control unit operatively connected to the start engine actuator, the throttle control valve and the electric motor, the at least one control unit configured to start the internal combustion engine upon actuation of the start engine actuator, rapidly increase the open angle of the throttle control valve immediately upon starting the internal combustion engine rapidly to increase engine speed of the internal combustion engine to a desired peak engine speed, and then couple the electric motor to the internal combustion engine to rapidly decrease engine speed as soon as the internal combustion engine reaches a desired peak engine speed.
