METHOD AND SYSTEM FOR PERFORMING AN EXHAUST GAS ANALYSIS ON MOTOR VEHICLES HAVING AN ON-BOARD ENGINE CONTROL AND DIAGNOSTIC SYSTEM

摘要

The aim of the invention is to enable the performance of an exhaust gas analysis, in a manner that is largely automatic, on motor vehicles having an on-board engine control and diagnostic system (OBD) and equipped with a diagnostic interface. To this end, control commands (15) are generated, preferably in an exhaust gas tester (12), and are transmitted via the diagnostic interface (3) to the engine control and diagnostic system (2) that, according to the control commands (15), adjusts the operating states of the motor vehicle (1), which are prescribed for the exhaust gas analysis.
