Application of vehicle\u27s CAN based network in transmission service load data acquisition

Primjena raznih elektroničkih podsustava u putničkim automobilima i različitim vrstama cestovnih i drugih vozila u stalnom je porastu. Stoga nova vozila, umjesto mehaničkih sustava, postaju napredni mehatronički sustavi za čiji je razvoj i ispitivanje potreban novi pristup. Mogućnost korištenja podataka s mreže vozila čini se izvanredno snažnim alatom na njoj. Članak se bavi novim pristupom za mjerenje i dobivanje podataka o radnom opterećenju kao korisnom alatu u razvoju i ispitivanju vozila. Zbog kompleksnosti sustava i različitih komunikacijskih protokola na mrežama vozila smatralo se izvanredno praktičnim rješenjem stvoriti pristup koji će se zasnivati na standardima koji su široko prihvaćeni u industriji. Novi se pristup temelji na platformi hardvera i softvera usmjerenoj glavnim upravljačima vozila sa zadatkom prikupljanja podataka koji postoje na mreži i koji su relevantni za radno opterećenje mjenjača. Mogućnosti spomenutog hardvera kao i softvera trebaju omogućiti upravljanje sustavima vozila temeljeno na računalu i tako biti alat za razvoj novih vozila. Novi je sustav bio testiran u stvarnoj upotrebi. Ustanovilo se da je pomoću sustava potrebno mnogo manje vremena za podešavanje instrumenata vozila prije ispitivanja i dobivanja točnih podataka.The implementation of various electronic subsystems in passenger cars and different kinds of on-road and off-road vehicles is constantly expanding. Accordingly the new vehicles, instead of being mechanical systems, become advanced mechatronic systems whose development and testing call for a new approach. Possibility of using data available on vehicles network seems to be extremely powerful tool on it. The paper deals with a new approach for service load data measurement and acquisition as a helpful tool in development and testing of vehicles. Based on complexity of the system and different communication protocols on the vehicles\u27 networks it was found as extremely practical solution to make approach which will be based on standards which are widely accepted by the industry. The new approach is based on hardware and software platform oriented to the main vehicle controllers with the task to acquire data which exist on the network and which are relevant to the transmission service load. The said hardware as well as software utilities have to enable computer based monitoring of the vehicle systems behaviour and in that way to be the tool for new vehicles development. The new system was tested in real service. It was found that the system can enable significantly less time of vehicle instrumentation before testing and accurate data acquisition
