Bit wise arbitration and priority in CAN Bus

[alefandra]

Hello everybody!
I´m learning about CAN Bus operation, but I don´t understand how collisions can be avoided. I know that bus access conflicts are resolved by bit wise arbitration and a priority but can anybody explain me this bit level a little bit better? By the way, has anybody some good documents related with the CAN Bus physical layer?? I´ll really appreciate any help!!! Thank you!!!
