WebApr 26, 2024 · CAN bus considers the 11 bit indentifiers to have a higher priority than the 29 bit identifiers (because the two types of "protocol", "11" and "29", can coexist in the same bus). Hence: In the case of a 29 bit extended frame, the RTR bit has been moved to the end of the message so it doesn't play in the priority bitwise arbitration of the 29 ... WebSecure CAN bus. As shown in recent CAN hacker attacks, Classical CAN is vulnerable. If hackers gain access to the CAN bus (e.g. over-the-air), they could e.g. turn off critical functions.
