The three major automobile buses CAN, LIN, Flexray

 


Today, society has entered the era of information network. People hope that the car is not only a means of transportation, but also an extension of the scope of life and work. The car is like staying in one's own office and home. Phone, Internet, entertainment, work.


  
The most familiar car bus is CAN, and you may be a little unfamiliar with LIN and Flexray. So next, I will introduce these three kinds of car buses to you.

 


First, the birth of the car bus

 

The birth of automobile bus is inseparable from the development of automobile electronics. The degree of automotive electronics is also regarded as an important indicator to measure the level of modern automobiles.

 

According to statistics, in a high-end car using traditional wiring methods, the wire length can reach 2,000 meters, and the electrical nodes can reach 1,500, and this number will double about every 10 years.

 

This further exacerbates the tension between the bulky wiring harness and the limited space available on the car. Regardless of material cost or work efficiency, traditional wiring methods cannot adapt to the development of modern automobiles.

 

Therefore, the traditional electrical network has been unable to adapt to the development of modern automotive electronic systems, so the new automotive bus technology came into being.

 

2. CAN bus

 

CAN bus, also known as automobile bus, full name of Controller Area Network, is a serial communication network that can effectively support distributed control and real-time control. It connects the individual control units in some form to form a complete system.

 

CAN bus is a serial communication protocol developed by German Bosch company to solve the data exchange between numerous electronic control modules and ECUs in modern automobiles.

 

Nowadays, it has been widely used in automotive electronic systems and has become the main industry standard of the European automotive manufacturing industry, representing the mainstream development trend of automotive electronic control networks.

 

3. LIN bus

 


The LIN bus is mainly used in the distributed electronic control system in the car, especially in the digital communication occasions for intelligent sensors or actuators.

 

The number of nodes in a typical LIN network can reach 12. Taking door and window control as an example, there are door locks, window glass switches, window lift motors, operation buttons, etc. on the door. Only one LIN network is needed to connect them as one.


 
And through the CAN gateway, the LIN network can also exchange information with other systems in the car to achieve richer functions. At present, LIN has become an international standard and is accepted by most automobile manufacturers and parts manufacturers.

 


4. Flexray bus

 

Flexray is a high-speed, deterministic, and fault-tolerant bus technology for automobiles. It combines event-triggered and time-triggered methods. It has the characteristics of efficient network utilization and system flexibility. As the backbone of the new generation of automotive interior networks.

 

Flexray is a high-speed, deterministic, and fault-tolerant bus technology for automobiles. It combines event-triggered and time-triggered methods with efficient network utilization and system flexibility. , which can be used as the backbone network of the new generation of automobile internal network. It can be used in passive bus and star network topologies, and can also be applied in the combined topology of the two. Both topologies support dual-channel ECUs that integrate multiple system-level functions to save production costs and reduce complexity. The dual-channel architecture provides redundancy and doubles the available bandwidth. The maximum data transfer rate per channel reaches 10Mbps. At present, Flexray is mainly used in safety-related wire control systems and power systems, and it is used in BMW's high-end cars.
