The development momentum of intelligent networking technology in China is quite rapid. With the advent of the development trend of automobile intelligence and networking, intelligent networked vehicles have gradually become the main trend of automobile development. More and more automakers are requesting that they can provide measurement software with local characteristics, especially for ADAS testing. The new version of Q-Vision software launched by Softing China supports ADAS testing and can be customized based on domestic customer needs. As a professional supplier of CAN bus technology worldwide, Kvaser focuses on hardware development. The CAN/LIN hardware products under its brand are stable, reliable, and cost-effective. They are widely used by major automakers and auto parts customers During the development and testing process.
| Product Introduction
· Q-Vision
Q-Vision is a new bus analysis, measurement and calibration, and ECU diagnosis tool, which has been put into use in many automakers.
Q-Vision supports CAN (FD), LIN, Ethernet, LVDS and other vehicle network standards, as well as CCP / XCP / UDS / OBD and other protocols, and can import databases in DBC / LDF / ARXML / A2L / ODX formats.
The supported ADAS test functions are as follows:
1. Display the sensor data of ADAS test requirements:
· GPS data (display navigation information on the map);
· LiDAR lidar;
· RADAR millimeter wave radar;
· Camera, etc.;
2. Data fusion:
Q-Vision can call external data algorithms through the Simulink/Python interface, thereby fusing sensor data and displaying it in the same window.
· Kvaser products
Kvaser has many products in CAN, CAN FD, LIN bus, and can be developed for products with the same API and compatible with each other, and can be used for online recording, simulation, monitoring, diagnosis, calibration, flashing, etc.

| CAN/CAN FD Solution
Using the combination of Q-Vision PC software and Kvaser hardware can realize the functions of CAN/CAN FD/LIN bus network monitoring, data analysis and acquisition, diagnosis, calibration and so on. For different test requirements, different types of connectors such as DSUB9, OBDII, M12 can also be flexibly selected, and multiple nodes can be monitored online at the same time, which is an indispensable tool in the entire V-Mode development process.
· CAN(FD) solution
1. CAN (FD) signal acquisition
In the Q-Vision software, you can configure the hardware device in the Device Configuration of the Start interface, select the CAN or CAN FD mode, configure the baud rate, and import the DBC file according to your needs.
The collected CAN (FD) signal can be displayed in the Trace window, respectively displaying the message CAN channel, CAN ID, Name, DLC, Data, time and other information. Q-Vision supports signal filtering and filtering.
2. CAN(FD) sending function
Q-Vision supports sending CAN (FD) messages. You can choose the CAN channel for sending CAN messages. It supports extended frames. The DLC is up to 64 bytes. The Message Data can be defined by yourself. You can also click Randomize Data to generate random data.
3. CAN(FD) statistics display
After the CAN (FD) Channel selects the corresponding CAN channel, the CAN load rate will be counted and displayed, including the maximum load and the minimum load, and the average load. It also counts the amount of bytes and the amount of messages.
4. CAN(FD) data playback function
Q-Vision supports the addition of asc message files for sending. You can choose the CAN channel file, file address, and sending interval period for sending, and send all the data in the file.
| ADAS test
Q-Vision is connected to data acquisition equipment through Kvaser communication card, or connected to a bus network, which can analyze data and generate cloud images online to complete cloud-integrated ADAS testing.
1. GPS data collection
Q-Vision provides reliable GPS data collection function, which can realize highly accurate positioning and image display.
2. Camera video signal collection
Q-Vision provides the function of video signal collection and display, which can monitor the external environment information of the vehicle more conveniently. At the same time, it can also set the collected video and select the corresponding video signal source.
3. Ibeo lidar acquisition
By setting the radar IP and port number, the requirement of displaying the top view of the lidar data can be achieved.
Use Q-Vision software with Kvaser hardware products to realize online recording, simulation, monitoring, diagnosis, calibration, flashing and other functions of various bus networks. At the same time, it supports ADAS testing, which provides customers with more convenient, Fast and reliable choice.
