KIA P2M Posts Favorito High-Speed Controller Area Network (CAN) Basics If the High-Speed Controller Area Network (CAN) is something you don’t deal with often, here are a few basics to refresh your memory. Controller Area Network (CAN) Standard protocol for communication between vehicle control systems.Developed because vehicles have increasing numbers of electronic control systems that require communication between individual control units.CAN control units are connected in parallel (e.g., ECU, TCU, ADAS*, and ESC*) and upload their data to the network (or BUS) so it can be shared with other control units that need this data.Key AdvantagesSimple structure capable of fast communicationRequires less wiring and lowers vehicle weightProvides efficient system controlReduced costEase of adding and controlling different devices on the CAN busTwisted-pair wiring is highly tolerant to electrical noise, so data is protected Wiring Basics CAN Wiring Twisted pair wiringTolerant to electrical noise Terminating Resistors 120 Ω eachAt the ends of each networkPrevents reflective signal waves and stabilizes voltage signal Communication Waveform There are two signals: CAN High and CAN LowThese two signals have opposite phases (binary data) Waveform Scope Pattern CAN High rises to 3.5 V from 2.5 VCAN Low drops to 1.5 V from 2.5 VVoltage level is used as a data communication languageBinary numbers for this language are translated by measuring the output voltage differences As always, use KGIS to find the most current service information, and thank you for supporting Kia Technical Training!
