The necessity of USBCAN II FD in car CAN
As we all know, rainy weather is often encountered in the UK.The driver's sight will be hindered to a certain extent. This is still the case when the rain is not much hit, what if the heavy rain? I'm afraid that the refresh rate of the wipers can't keep up with the frequency of rain covering the windshield! Because I have encountered similar situations several times in the past few years, I am convinced of this. In addition, if it rains, it will lubricate the tires of the car, causing the car to lose part of its grip. It may be able to brake at a distance of 30 meters with a braking distance of 30 meters. The friction of the ground is reduced, it may take 40 meters to achieve the goal. At a speed of 60 mph, the distance is more than 10 meters, please make up for this consequence by yourself. Therefore, on the one hand, we should reduce the number of driving on rainy days to avoid disasters at the same time. At the same time, if we really have to drive in rainy weather, on the one hand, we must have higher than usual driving attention, on the other hand, The speed should not be too fast.A leaning car should be a car with no hardware or software problems. The hardware of the car is the part that we can usually see, such as the engine tires. The software refers to the control bus of the car and the like. Now it is generally the CAN bus because of its fast data transmission speed and strong anti-interference ability. Many, the data transmission distance is long. However, because more and more electronic devices are integrated in the current car, the control bandwidth of the bus is greatly dispersed. This is not good news, and sometimes it is almost fatal.
The reason why we used the CAN bus as the control bus of the car was because the maximum data transmission speed could reach 1000Kbps. This data transmission speed allows the car to be truly banned, and the data transmission is very good. But we also said above that there are more and more electronic devices in the car, and the bus bandwidth that may be allocated to the power of the car is not as much as before, and the reaction time of the car becomes longer. For the rest, everyone else thinks about it. So, can't we get more CAN buses on a car? Of course, in fact, many cars are doing the same, but it should be noted that the more CAN buses you have on a car, the more difficult it is to develop and the higher the cost. At the same time, there are too many buses, what to do if they interfere with each other? During the later maintenance, did the difficulty of this maintenance suddenly increase? These are all problems. Although a few more CAN buses are currently a good solution to the problem, after all, it is not a long-term solution. The shotgun changing the gun makes the data transmission speed wider and the CAN FD with a larger bus bandwidth gradually the CAN bus is the right way.
Compared with the CAN bus, CAN FD has not changed much in the overall structure, but the data transmission speed has reached more than five times the previous, at the same time, the number of data bits also increased from 8 to 64 bits, which allows The transmission is more stable and not easy to drop frames. Because it is similar to the CAN bus, we do not need to change the original hardware and software facilities when using it. You only need a car can box that can convert CAN bus data and CAN FD bus data. For example, the USBCAN II FD of Shenyang Guangcheng Technology.
