Which side should be responsible for a correct CAN dbc ? Developer or car factory ?

Here is the problem I met:

The car factory provided both CAN matrix and CAN dbc, unfortunately the CAN dbc , when imported into davinci tool, reads many issues, the developer had to manually modify the dbc to make it work.

My question is : can we insist that the car factory should provide a correct CAN dbc ? Or should the developer generate CAN dbc himself from the CAN matrix ?

Which side should be responsible for a correct can dbc ? Developer or car factory ?

Thank you very much !

  • This all boils down to if the correct format is required by some standard and if compliance/cerification against that standard is a thing. In this case I believe it's just some proprietary format by Vector, so nobody is "responsible", it's just a tool. –  Jul 15 '22 at 08:48

What are you asking, "CAN dbc" to my knowledge is a data descriptor file originally by Vector. This should probably be asked of your legal department, these things are not normally given out to the general public and without a NDA (Non Disclosure Agreement) or something like that. That document should give you a course of action to follow. It also depends on contracts and if you are a first, second, third tier supplier. There is not enough information to begin to answer your question. It also depends on the OEM, country etc. My suggestion take it to a legal forum.

  • Thank you for the reminder. Surely I have signed NDA. –  Jul 15 '22 at 06:41
  • My question was : if the Car supplier has provided a wrong dbc, what should I do ? Ask them to provide again ? Or I generate one ( from can matrix ) by myself ? –  Jul 15 '22 at 06:42
