APPLICATION OF VEHICLE'S CAN BASED NETWORK IN TRANSMISSION SERVICE LOAD DATA ACQUISITION

The implementation of various electronic subsystems in passenger can 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' networks it was found as extremely practical solution to make approach which will be based on standards which are widely accepted by die 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 mat 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.Original Abstract: Primjena raznih elektronickih podsustava u putnickim automobilima i razlicitim vrstama cestovnih i drugih vozila u stalnom je porastu. Stoga nova vozila, umjesto mehanickih sustava, postaju napredni mehatronicki sustavi za ciji je razvoj i ispitivanje potreban novi pristup. Mogucnost koristenja podataka s mreze vozila cini se izvanredno snaznim alatom na njoj. Clanak se bavi novim pristupom za mjerenje i dobivanje podataka o radnom opterecenju kao korisnom alatu u razvoju i ispitivanju vozila. Zbog kompleksnosti sustava i razlicitih komunikacijskih protokola na mrezama vozila smatralo se izvanredno prakticnim rjesenjem stvoriti pristup koji ce se zasnivati na standardima koji su siroko prihvaceni u industriji. Novi se pristup temelji na platformi hardvera i softvera usmjerenoj glavnim upravljacima vozila sa zadatkom prikupljanja podataka koji postoje na mrezi i koji su relevantni za radno opterecenje mjenjaca. Mogucnosti spomenutog hardvera kao i softvera trebaju omoguciti upravljanje sustavima vozila temeljeno na racunahi i tako biti alat za razvoj novih vozila. Novi je sustav bio testiran u stvarnoj up
