Abstract
With the fuel economy and emission requirements more demanding than ever and passenger-car engine control systems more sophisticated than ever, there exists a need for a methodical procedure to optimize the fuel economy subject to emission limits of the entire engine-vehicle-aftertreatment system over the federal fuel economy and emission tests. The optimal feedback control functions should account for: 1) transient system interactions; 2) cold start engine-catalytic converter warm-up dynamics; 3) exhaust aftertreatment; 4) driveability; and 5) any repeatable unknown phenomena which affect end-of-test fuel consumption or emissions.
This paper presents an experimental Transient System Optimization (TSO) procedure which meets these requirements.
