What is CAN in automotive?
CAN, a high-integrity serial bus system for networking intelligent devices, emerged as the standard in-vehicle network. The automotive industry quickly adopted CAN and, in 1993, it became the international standard known as ISO 11898. Since 1994, several higher-level protocols have been standardized on CAN, such as CANopen and DeviceNet.
When was the CAN developed?
CAN History. Bosch originally developed the Controller Area Network (CAN) in 1985 for in-vehicle networks.

Manufacturers began using more and more electronics in vehicles, which resulted in bulky wire harnesses ...
What is CAN bus?
CAN was first created for automotive use, so its most common application is in-vehicle electronic networking. However, as other industries have realized the dependability and advantages of CAN over the past 20 years, they have adopted the bus for a wide variety of applications.
What is an extended CAN?
Extended CAN uses a 29-bit identifier along with a few additional bits. An extended message has a substitute remote request (SRR) bit after the 11-bit identifier, which acts as a placeholder to keep the same structure as standard CAN. This time the identifier extension (IDE) should be recessive, indicating that the extended identifier follows it. The RTR bit is after the 18-bit ID and is followed by a second reserve bit, r1. The rest of the message remains the same.
What is CAN in electronics?
This article introduced the Controller Area Network or CAN. CAN is a robust serial communication bus found mostly in automotive and industrial environments. CAN uses a differential signal, which makes it more resistant to noise, along with a priority arbitration scheme for non-destructive message transmission. CAN is great for embedded applications that end up in hazardous environments or areas with a lot of electromagnetic interference. Whether you're building a remote-controlled submarine, setting up a microbrewery with pumps and sensors, or just hacking your car's computer, CAN is a great way to further your embedded knowledge while beefing up your next design project.
What is a can bus?
CAN uses a multi-master bus, where all messages are broadcast on the entire network. The identifiers provide a message priority for arbitration. CAN uses a differential signal with two logic states, called recessive and dominant. Recessive indicates that the differential voltage is less than a minimum threshold voltage.
What is CAN in CSMA?
CAN is a CSMA/CD protocol, meaning each node on the bus can detect collisions and back off for a certain amount of time before trying to retransmit. This collision detection is achieved through a priority arbitration based on the message identifiers. Before we discuss arbitration, let's take a closer look at the dominant and recessive bits used on the CAN bus.
