The OBD decoding function of USBCAN for vehicle

Engineers in the development of vehicle and vehicle electronics often need to obtain data such as vehicle speed and engine speed from the CAN bus of the car. The usual way to obtain data is to use the USBCAN device to analyze the original CAN bus data receiving from the vehicle, or use the original diagnostic instrument provided by the manufacturer. But the first method requires a higher level of data analysts' ability, while the second method requires an original diagnostic device at a very high cost.

GCAN has added OBDII decoding function to Ecantools software for this kind of demand of USBCAN analyzer. This function is only supported by Pro series USBCAN device. It can obtain and analyze information such as speed, speed, water temperature, voltage, mileage, etc by connecting USBCAN to CAN bus of car CAN bus. It helps reduce the barriers of analysts and improves the efficiency of data analysis. Let's take a look at a recent case.

Dialogue:
Engineer Li (from a car factory): We are engaged in the development of vehicle parts. We want to read the engine speed, engine speed, remaining fuel, door status, and turn signal status. Do you have any good plans?

GCAN: The data of the speed, engine speed and remaining oil are in accordance with the standard 15765 protocol. It can be directly parsed and displayed through the OBDII interface of our Ecantools software. The door status and turn signal data are not standard protocols. The agreement is different for each type of vehicle, so there is no way to make a direct analysis. It can only be parsed by yourself via the original data of the CAN bus.

Engineer Li: Is it complicated to analyze the specific meaning of the original data through the CAN bus? What kind of people can do it?

GCAN: This part of the work needs engineers with certain experience to do. The data analysis work itself is not difficult, but it is difficult to find the corresponding data. The car CAN bus data is sent in an infinite loop, and about 3,000 per second. Although there are so many data, Ecantools software for USBCAN has many useful functions to help you find this data. Here is a video for your reference about how to operate. https://v.qq.com/x/page/b0531jkqpsb.html

Engineer Li: Ok, let me take a look at this video. If you have any questions, can you help us?

GCAN: Of course, please contact us if you have any questions.



USBCAN

Using the traditional USBCAN device to collect CAN raw data analysis, the analyst is required to be higher. Using the OBDII function in Ecantools software to parse the data specified in the 15765 protocol not only reduces the technical threshold, but also visualizes it with an interface similar to a car dashboard. GCAN also reminds that when using non-original equipment to collect data from the car OBD port, be sure to check if the car OBD port has a gateway first. If the OBD port has a gateway, you need to connect the USBCAN device to CAN bus directly to collect data.
