Introducing the easy-to-use CAN bus transceiver USBCAN II FD
In order to cope with the actual situation in which more and more electronic devices are integrated in automobiles, automotive developers intend to make the CAN FD bus the first choice to undertake the transition between the CAN bus and the flexray bus. Because, in the following aspects, CAN FD bus has unparalleled advantages of other buses:
Advantage 1: Intimacy with CAN bus
From the name, we can see that although the CAN bus and CAN FD bus are not the same thing, they are definitely related by blood. In fact, this is also the case. In fact, we can simply view the CAN FD bus as the optimized and upgraded version of the CAN bus, especially in the attribute of data transmission speed, CAN FD has made a breakthrough improvement compared to the CAN bus. Because of their similar structures, there are fewer areas that need to be modified in bus development, the difficulty of development is reduced, and the costs of various types are not so high. The resistance to application is not very large. This is the CAN FD bus has become the next generation car. The most important reason for the bus.
Advantage two: CAN FD itself is powerful
As a type of bus that is mainly used in automobiles, the CAN FD bus not only inherits the CAN bus data transmission distance, connects node devices, and has strong anti-interference ability. It also has qualitative data transmission speed. improve. Friends who are more familiar with the CAN bus know that the theoretical data transmission speed of the CAN bus does not exceed 1000Kbps, and in actual use, due to physical losses and other reasons, the bus bandwidth can be 500. Because the available bandwidth is only about 500, but it has to bear the control of electronic products on the entire car, so many cars retreat second, often not let the entire car use CAN bus control, but only let the CAN bus be responsible for those cores The control operation of the equipment, like the less important place, is supplemented by the LIN bus. However, people's needs are unlimited. Who doesn't want to make their cars more and more perfect? Therefore, in order to make their car run faster and faster, many people choose to add more than one CAN bus to the car, but in this case, the cost also comes up, and the difficulty of later maintenance is also increased. So, can the bandwidth of the bus be expanded so that it can meet our needs without increasing the number of buses? CAN FD comes as promised, 1000Kbps is not enough, 5000 is not enough?
Advantage three: The number of data bits on the CAN FD bus has increased a lot, improving the efficiency of data communication.
Why are the production methods in large factories now all in assembly line production? Because it allows you to concentrate on a certain thing, save a lot of useless work, and improve the efficiency of your work. The number of data bits on the CAN FD bus has reached 64, while the CAN bus has only 8 bits. Perhaps a few CAN FD bus data can cover more than a dozen dozens of CAN bus data, and reduce data and data Between the additional operations, this efficiency improvement is obvious, and for the control of the car, the safety has also been improved to a certain extent.
