what is a controller area network (can)? -凯发k8网页登录

controller area network (can) is a vehicle bus standard that enables microcontrollers and devices to communicate with each other within a vehicle. can is a message-based protocol originally designed for automotive applications, but it is also used in industrial automation and other areas.

can fd is a newer standard that supports higher speeds and larger data frames than can. whereas can is limited to speeds of 1mbit/sec and data frames of 8 bytes, can fd can be used to send data at 5mbits/sec using data frames of 64 bytes.

vehicle network toolbox™ provides matlab^® functions and simulink^® blocks for sending, receiving, encoding, and decoding can and can fd messages.

design and test engineers use vehicle network toolbox to connect directly to controller area network busses via a variety of can interface hardware to perform tasks such as:

• testing and debugging controls algorithms by replaying can messages collected during in-vehicle tests
• filtering, encoding, and decoding can messages to support testing, simulation, and analysis
• calibrating ecus by sending and receiving messages using xcp protocol over can
