Diagnostika avtomobila z mikrokrmilnikom Arduino

Marolt, Blaž (author), Šter, Branko (mentor)

V Evropi je že od leta 2001 v avtomobilih po zakonu uporabljen protokol OBD2, ki je standarden za vse avtomobilske proizvajalce. Protokol je bil zasnovan leta 1969, predstavljen pa leta 1980. Takrat je omogočal samo to, da so lahko mehaniki brali statuse različnih podsistemov v avtomobilu. Od takrat naprej je njegova uporabnost naraščala do te mere, da lahko danes prikazujemo različne parametre avtomobila v realnem času, beremo zabeležene napake, jih brišemo in spreminjamo. Veliko teh parametrov lahko prikazujemo na potovalnem računalniku, vendar tega pri starejših avtomobilih ni. Cilj diplomske naloge je uporabiti mikrokrmilnik Arduino in vmesnik OBD2 ter z njima prikazovati in shranjevati parametre avtomobila. Končni izdelek bo montiran v avtomobil.

Abstract

Since 2001 in Europe cars use OBD2 protocol, which is standard for all automotive manufacturers. The protocol was designed in 1969 and introduced in 1980. At that time, it only allowed the mechanics to read the statuses of various subsystems in the car. Since then, its use increased to such extent that today we can show different parameters of a car in real time, read the recorded errors, as well as delete and modify them. Many of these parameters can be shown on the trip computer, but not in older cars. The aim of this thesis is to use the Arduino microcontroller and OBD2 interface and use them to read and save the car’s parameters. The final product will be installed in a car.
