BOOST PRESSURE DETERMINATION METHOD AND APPARATUS, STORAGE MEDIUM AND DEVICE

Disclosed in the present application are a boost pressure determination method and apparatus, a storage medium and a device. In the technical solutions provided by the embodiments of the present application, by introducing the concepts of a target exhaust back pressure and a target exhaust flow into boost control logic, decoupling with an actual exhaust back pressure and an actual VGT opening degree can be realized, thus avoiding boost control overshoot caused by coupling; moreover, using the target exhaust back pressure and the target exhaust flow for calculation can effectively minimize the situation that a VGT is in a relatively-large-degree closed state for a long period of time under a dynamic working condition (Tip-In), so as to prevent the exhaust back pressure from rising too fast and too high, and aid in rapid establishment of the volumetric efficiency, thus further improving the driving performance of vehicles.
