Résumé / Abstract
A better knowledge of vehicle usage and of vehicle and engine operating conditions is highly required when defining realistic test conditions for measuring pollutant emissions or fuel consumption on a test bench, for validating laoratory results, for modelling or drawing-up national or local inventories of pollutant emissions. With the aim of defining typical vehicle real-world operating conditions, a database on actual vehicle use has been built-up within the EEC research program, drive modem. An experimental study was carried out by INRETS in France, Tüv-rheinland in Germany and TRRL trips and 73,000 kilometers were monitored, during which the vehicle speed, engine speed, temperatures and other variables were recorded at one second time intervals. The method used to record vehicle operating conditions is widely discussed and is extended to duty vehicles. Tools and methods developed for constructing test cycles are described.
