Abstract
A system according to the principles of the present disclosure includes a throttle limit determination module, a throttle area adjustment module, and a throttle control module. The throttle limit determination module determines a throttle limit based on an intake cam phaser position. The throttle area adjustment module adjusts a desired throttle area based on the throttle limit when the desired throttle area is greater than the throttle limit. The throttle control module controls a throttle opening area of a throttle valve based on the desired throttle area.
Claims20
A system comprising:
- a throttle limit determination module that determines a throttle limit based on a position of an intake cam phaser that regulates an opening timing of an intake valve;
- a throttle area adjustment module that adjusts a desired throttle area based on the throttle limit when the desired throttle area is greater than the throttle limit;
- and
- a throttle control module that controls a throttle opening area of a throttle valve based on the desired throttle area.
A method comprising:
- determining a throttle limit based on a position of intake cam phaser that regulates an opening timing of an intake valve;
- adjusting a desired throttle area based on the throttle limit when the desired throttle area is greater than the throttle limit;
- and
- controlling a throttle opening area of a throttle valve based on the desired throttle area.
