Abstract
Embodiments for controlling boost pressure in a turbocharged engine are provided. In one embodiment, a method for an engine having a throttle comprises, if an inferred throttle inlet pressure (TIP) value is different than a measured TIP value, adjusting a wastegate of a turbocharger based on the inferred TIP value and not based on the measured TIP value, the inferred TIP value based on air flow through the throttle, throttle angle, and manifold absolute pressure (MAP). In this way, boost pressure control may be provided by the inferred TIP value under some conditions.
