ABSTRACT:
An engine control system that regulates first and second throttles of an internal combustion engine includes a primary control module that generates a throttle area based on an operator input and a second control module that determines a second throttle position based on the throttle area. The second control module determines a redundant throttle position based on the throttle area and regulates a position of the second throttle based on the second throttle position if the second throttle position and the redundant throttle position correspond with one another.
