A Controller Area Network (CAN) in a vehicle or machine is analogous to the nervous system of a living organism.
By extending the analogy, sensors in a controller circuit can be compared to receptors, and an electronic control unit (ECU) can be seen as a sensory neuron system with a specific purpose that connects receptors and the central nervous system.
CAN-BUS systems establish communication channels between the electronic control units in a vehicle, enabling the transfer and analysis of gathered data.
There was no effective method of cross-communication between ECUs until CAN-BUS was created. CAN-BUS is efficient by delivering the most critical messages first, through a prioritisation mechanism of source ID-encoded signals utilising the binary unit system (BUS) (BUS).
This setup is incredibly reliable, with a high capacity for both signal error detection and hardware cross-wiring functionality.
This structure is fully distributed, which allows for a single access point for all the desirable information collected. CAN-BUS is a basic, low-cost technology that decreases the overall harness weight and amount of wiring needed in a vehicle, enhancing the quality of sent data in contrast to harness-connected electrical structures.
The Global Intelligent CAN bus controller market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
ZigBee is a wireless networking standard that is widely used for home-area networks that manage and monitor connected items.
ZigBee is advantageous for sensor and car network applications because of its low installation and operating costs, long battery life in comparison to competing devices, minimal maintenance requirements, security and dependability, and tiny physical device footprint.
The IEEE 802.15.4 technical standard, which specifies the physical layer (PHY) and medium access control (MAC) sublayer for low-data-rate wireless personal area networks (LR-WPANs), is the foundation upon which ZigBee was developed.
When installing systems, adding, and deleting nodes, updating systems, and building larger networks, CAN-BUS to ZigBee conversion has proven advantageous in terms of flexibility, convenience, and use.
The wireless technology known as ultra-wideband (UWB) is also being investigated for use in vehicle communication systems.
A low-power radio protocol called UWB was developed primarily to boost wireless technologies’ ability to pinpoint their exact position.
The time it takes for a radio signal to travel between the sending and receiving devices is measured when data is transmitted over a short distance using UWB.
This resembles the time-of-flight (ToF) approach used with radio detection and ranging (RADAR). A UWB transmitter broadcasts billions of radio pulses at a 7.5 GHz wide-spectrum frequency.
From a UWB receiver, these pulses are subsequently converted into useful data. UWB has been investigated for application in path localization and autonomous vehicle navigation, even though it is not frequently used in conjunction with CANBUS.
