Model-based control for automotive cold start applications

Abstract

Hydrocarbon emission during start-up of automotive engines has proved to be a thorny problem in powertrain control design due to its requirements conflicting with smooth, reliable start and fast warm-up. This paper surveys research at UC Berkeley toward better design of control algorithms, by capturing more of the physical behavior of the engine, the complexity of the control requirements and the characteristics of the embedded software, by the use of mathematical models. The status and future directions for modeling and control design efforts are outlined.
