Patent ID: 8805606

Claim:
A pneumatic booster controller, comprising: a controller configured to receive vehicle operating parameter information and to transmit pneumatic booster actuation commands to pneumatic booster actuation devices over at least one of a CAN bus network and dedicated signal circuits, wherein the controller is programmed to control a pneumatic boost event based on at least one monitored operating parameter of the vehicle by coordinating the operation of at least one compressed air flow control valve which controls admission of compressed air into an intake of an engine and an intake block-off element which blocks off the intake to prevent back-flow of compressed air in the intake, and controlling compressed air injection during the pneumatic boost event by adjusting a compressed air injection profile for opening and closing the at least one compressed air flow control valve by adjusting at least two of compressed air injection rate, duration and timing of at least two air injection pulses during the pneumatic boost event so as to maintain at least one monitored operating parameter of the vehicle within a predetermined range.
