The new European Legislation requires new strategies in order to achieve a reliable emission diagnostic over the entire life of the vehicle (EOBD).For the validation and the fine-tuning of the new diagnostic controls, the car manufacturers must manage fleets of vehicles in order to evaluate the behavior of these diagnostics over a real aging cycle.This paper describes a useful tool that has been developed to check the most important diagnostic indexes behavior with aging, that help us in the management of a durability fleet.The system is composed of: During the use of durability car the system runs automatically and does not require any additional operation to the driver (“black-box system”), and no additional skilled people is required for the data acquisition.Periodically data of each car of the fleet are collected and stored in a personal computer where an expert engineer will analyze the behavior of the fleet with the off line software.
