1. A control system for a hybrid vehicle comprising:
- a regenerative braking module that controls regenerative braking of the hybrid vehicle when an accelerator device of the hybrid vehicle is not engaged; and
a throttle-by-wire control module that controls a throttle valve, and that at least one of opens said throttle valve and holds said throttle valve open in response to regenerative braking module signals when a transmission of the hybrid vehicle is in gear.

Abstract
A control system for a hybrid vehicle includes a regenerative braking module that controls regenerative braking of the hybrid vehicle. Regenerative braking is controlled when an accelerator device is not engaged. A throttle-by-wire control module controls a throttle valve. The throttle-by-wire control module opens the throttle valve and/or holds the throttle valve open in response to regenerative braking module signals when a transmission of the hybrid vehicle is in gear.

9. A control system for a hybrid vehicle comprising:
-
an accelerator pedal; an accelerator pedal sensor that senses movement of said accelerator pedal; a throttle valve; an engine that is responsive to control of said throttle valve; an engine control module that controls fuel flow to said engine based on accelerator pedal sensor signals; a transmission; a regenerative braking module that controls regenerative braking of the hybrid vehicle based on said accelerator pedal sensor signals; and a throttle-by-wire control module that at least one of opens said throttle valve and holds said throttle valve open in response to regenerative braking module signals when said transmission is in gear and when said engine control module shuts off fuel to said engine. - View Dependent Claims (10, 11, 12, 13)

14. A method for controlling a hybrid vehicle system comprising:
-
controlling regenerative braking of the hybrid vehicle based on acceleration commands; shutting off fuel to an engine of the hybrid vehicle during said regenerative braking; and opening a throttle valve during said regenerative braking when a transmission of the vehicle is in gear. - View Dependent Claims (15, 16, 17, 18, 19, 20)
