Abstract
A computer simulation method is presented that par tially replaces road testing of engines and other components of the power-drive system of urban buses. To calibrate the model, experiments were performed in the urban traffic of Warsaw using a digital data- acquisition system. Analysis of the recorded data showed that two types of vehicle runs were represent ative of urban traffic; models of them were developed and verified. Specific performance criteria were selected for optimum matching of engines and power- transmission systems. A computational procedure based on the models and performance criteria is described. Finally, the paper presents an applica tion of this simulation method to improving the fuel economy and dynamics of a city bus.
