A method for evaluating driving technique and engine operation, with emissions constraints, on a real driving route, is presented. A single degree of freedom vehicle model with simple resistive forces is driven along the pre-planned route. Instead of the velocity trajectory being determined a priori, the optimisation can choose the optimal speed along the route as well as the engine operating point. When constraints on the total emissions are imposed, the engine no longer operates on the minimum fuel locus; the power delivery changes as the emissions constraints are tightened. The driving technique changes from a series of bang-bang switches, into a smoother application of the engine power. The route is driven in the absence of stops and traffic restrictions.
