On Board Diagnostics
Račanský, David ; Šebesta, Jiří (referee) ; Dřínovský, Jiří (advisor)
This bachelor thesis deals with design of a simple diagnostic board computer of a car. The solution is divided into 2 parts. The first part is focused on the hardware implementation, which is based on the use of integrated circuit ELM323. This circuit contains 6 basic communication protocols for diagnostic purposes. Communication here has been modified from the original version of RS232 on USB with the help of FTDI. The proposed software solution was realized in C++ Builder 6.0 programming tool. It contains 9 modes, which include all types of vehicles subject to the ISO 9141 and ISO 14230 communication standards for automotive diagnostics. It can detect the type of defect, if defined and listed in the relevant table. Storage and retrieval of gained data are obvious.
