Abstract
A throttle control system includes a pressure comparison module and a throttle plate control module. The pressure comparison module determines an inlet pressure upstream from a throttle body and an outlet pressure downstream from the throttle body. The throttle plate control module controls a position of a throttle plate based on the inlet pressure and the outlet pressure.
Claims19
A throttle control system comprising:
- a pressure comparison module that determines an inlet pressure upstream from a throttle body and an outlet pressure downstream from the throttle body;
- and
- a throttle plate control module that controls a position of a throttle plate based on the inlet pressure and the outlet pressure during boost applications.
A throttle control system comprising:
- a pressure comparison module that determines an inlet pressure upstream from a throttle body and an outlet pressure downstream from the throttle body;
- and
- a throttle plate control module that controls a position of a throttle plate based on the inlet pressure, the outlet pressure, a desired mass air pressure (MAP) and a turbo basic pressure when an engine is started.
A method of controlling a throttle plate comprising:
- determining an inlet pressure upstream from a throttle body and an outlet pressure downstream from the throttle body;
- and
- controlling the throttle plate based on the inlet pressure and the outlet pressure during boost applications.
