Abstract
  • The problem of emission evaluation control and modelling is nowadays an open question. In the framework of a Decision Support System (DSS), a new approach was developed for modeling and evaluating automotive pollutant emissions. An interesting point of this proposal was the integration of the micro simulated model to obtain driving cycle. In fact an important open issue is the very expensive costs of experimental campaigns needed to obtain driving cycle statistically representative of driving behaviour. So to overcome these high costs and to extend the real vehicle operating conditions framework, a possible solution is to integrate a microsimulation model in the general context of emission modeling. But the reliability of driving cycles coming from simulation models must be evaluated with respect to the possible influence on test bench measured emissions. In this paper, we would try to present some results related to two aspects of the problem. The first one is the possibility to emphasize the acceleration features as a key variable in the development of an emission model. The second aspect is the opportunity to show the effect of an aggressive driving style with respect to a smoothing one both qualitatively and partly quantitatively. This effect can be assessed through an evaluation of the kinematic variables that characterize the driving cycle and through their produced pollutant values. A Kinematic Emission model (KEM) is used to calculate predicted values, both on real than on microsimulated cycles. Experimental tests are performed on a chassis dynamometer for characterizing regulated emissions and fuel consumption on a Euro 4 Panda Bi-fuel vehicle, on which simulated trajectories are analyzed.
