GBP: How Did CAN Bus Revolutionize The Automotive Industry?

Posted on by Smart Sites

The automotive industry has witnessed transformative innovation over the past few decades. Among these groundbreaking technologies, few innovations have had an impact as profound as the Controller Area Network (CAN) bus. The CAN bus, which first appeared in the 1980s, was designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. Its introduction marked a significant leap in how vehicle systems communicate. In this guide, we’ll find out what this technology entails and how it has transformed the automotive sector. The Origins of CAN Bus: A Solution to Complex Wiring In the 1980s, vehicles started integrating various electronic components, from anti-lock braking systems (ABS) to air conditioning units, each of which needed its own wiring. Traditional point-to-point wiring became cumbersome and expensive, with extensive cable networks creating inefficiencies in manufacturing and maintenance. The CAN bus system, developed by Bosch in 1986, provided a revolutionary alternative by introducing a single communication protocol that allowed various components to “speak” to each other over a shared data bus. With CAN bus, every electronic control unit in the vehicle—such as the engine control module, transmission, airbags, and braking system—could exchange real-time information across a single network. This simplification reduced wiring costs and weight, ultimately leading to more efficient, cost-effective manufacturing. How CAN Bus Works: The Backbone of Modern Vehicles The core function of the CAN bus is to facilitate communication between different electronic control units (ECUs), allowing these modules to share vital data. Unlike traditional systems where each component required a dedicated wire, the CAN bus uses two twisted wires (CAN High and CAN Low) through which information is transmitted. Each ECU can send and receive messages without requiring a complex web of cables. The CAN protocol operates on a multi-master, message-oriented structure. This design allows multiple ECUs to access the bus simultaneously and prioritize urgent messages—such as those from the braking system—over less time-sensitive information. Additionally, CAN bus is fault-tolerant, allowing it to continue operating despite minor errors or connection failures, making it ideal for the rigorous demands of automotive applications. Key Advantages of CAN Bus in Automotive Systems The shift to CAN bus in automotive design brought about several critical benefits: Reduced Wiring Complexity: By enabling all ECUs to communicate over a single network, CAN bus drastically reduced the wiring required, simplifying vehicle assembly and lowering manufacturing costs. Enhanced Data Transmission Speed: CAN bus offers rapid, real-time data transmission, allowing for efficient monitoring and response in critical systems like engine control and braking. Improved Fault Tolerance and Reliability: CAN’s fault-tolerant design supports reliable performance, even under adverse conditions, which is essential for the safety and dependability of modern vehicles. Scalability and Flexibility: The CAN bus is scalable, meaning that additional ECUs can be added to a vehicle without significant system redesign, providing manufacturers with greater flexibility. Transforming Vehicle Safety and Efficiency with CAN Bus The CAN bus paved the way for implementing advanced safety and efficiency features in vehicles, enabling communication between critical safety systems. For example, anti-lock braking systems, traction control, and electronic stability control rely on instantaneous data exchange to function seamlessly. CAN allows these systems to coordinate with each other, resulting in a more stable and safer driving experience. Beyond safety, the CAN bus also plays a crucial role in improving fuel efficiency. With the help of the CAN network, ECUs in charge of managing fuel injection, engine timing, and transmission can optimize these processes based on real-time data, enhancing overall fuel efficiency and reducing emissions. Real-World Applications: Autonomous Vehicles and Beyond As the automotive industry moves toward autonomous and electric vehicles, the demand for sophisticated, reliable communication systems like the CAN bus has grown exponentially. Autonomous vehicles rely on real-time data from various sensors, cameras, and ECUs to navigate and make split-second decisions. The CAN bus is central to these systems, supporting smooth data exchange between the numerous components that power autonomous functions. Electric vehicles (EVs) have also benefited from the CAN bus system, which helps monitor battery levels, manage temperature controls, and optimize power distribution. The scalability and reliability of the CAN bus make it an ideal fit for EV architecture, where precise and rapid data exchange is paramount. CAN Bus as a Key Driver for Industry 4.0 in Automotive Manufacturing The concept of Industry 4.0 emphasizes automation, data exchange, and smart technology integration in manufacturing processes. The automotive industry has been a significant adopter of Industry 4.0, with the CAN bus facilitating this transition by enabling data-driven insights and more responsive manufacturing lines. For instance, it enables predictive maintenance in production environments, where equipment connected via the technology can relay real-time performance metrics.

January 2023: Get now the PhysiCAN tool!

Posted on by hila@sitaltech.com

Sital Technology’s PhysiCAN is the only CAN/CAN-FD Physical Layer analysis tool available today.
It’s the successor to Sital’s earlier Buffalo product. PhysiCAN connects to a live CAN/CAN-FD data bus, and provides capability to detect disconnects and short circuits on the bus, along with estimates to their locations.

Based on Buffalo statistics collected from 20 OEM assembly plants in North America, CAN bus wiring faults occur in about 1% of the vehicles with 3 CAN buses, and as many as 5% in complex vehicles with 15 to 20 buses.
These involve with estimated average repair times of 6 hours. During troubleshooting, collateral damage cost incurred is estimated to be 10-fold. A technician using PhysiCAN is able repair such faults in an average of 20 minutes with minimal collateral damage.

“We are excited that the PhysiCAN analysis tool can expedite Rivian’s rapidly growing volumes. This will save these vehicles from collateral damage. We enjoy each time we get a fault report and hear comments such as ‘…seriously it took me 1 minute to find…’, followed by a picture of a bent pin” said Ofer Hofman, founder and CTO of Sital Technology.
In addition according to Hofman, “Sital looks forward to expanding the use of PhysiCAN into service, and later introducing the embedded version into the vehicles themselves to enable preventive maintenance”.
