From manufacturing to intelligent manufacturing, the difference of one word reflects the technical level of the whole vehicle in quality control. In today's era of big data, how to optimize processes to ensure high quality, and how to formulate more stringent test standards based on big data analysis and automated test procedures are all testing the advanced quality control capabilities of car companies.
Obviously, if you think about this problem simply from the traditional manufacturing system of automobiles, it is very difficult to make a big breakthrough. It's time for an injection of outside forces. With more than 30 years of ICT technology accumulation, Huawei's empowerment of its first smart car in terms of quality control may be a high reference value for the industry, and it can even be said that it has reshaped the quality control benchmark.
Start from the details and use detection to improve the user experience
Mobile phones and automobiles are both sophisticated and complex industrial products, although the number of parts is different, but there are many suppliers to provide a variety of components, which requires the car to be able to carry out an overall check on the parts provided by the supplier in the manufacturing process. Huawei's approach is to white-box the design of component suppliers, not only inspecting Tier1 suppliers, but even some of the suppliers' parts. At the same time, Huawei also requires suppliers to conduct full testing before leaving the factory to ensure the quality of each component during final assembly.
This is not enough, Huawei will also conduct functional tests on the incoming materials of each component manufacturer before loading, and finally upload the test data to the cloud big data quality inspection system for analysis, so as to improve the product quality of the vehicle and reduce the probability of repair.
In addition to the quality control of parts, Huawei has also transplanted the AI quality inspection that has been maturely used in mobile phone manufacturing to automobiles. For example, in the process of vehicle wiring harness plugging inspection in traditional OEMs, workers usually conduct self-inspection and cross-inspection by visual and tactile inspection to ensure that each connector is tightly connected. However, this method of manual detection is easy to make mistakes. In mobile phone manufacturing, Huawei has maturely applied the AI quality inspection solution to complete quality inspection of devices, labels, scratches, gluing, and other aspects, improving the inspection efficiency and accuracy compared with manual quality inspection.
Huawei has also brought this AI quality inspection solution to the final assembly and production of the Zhijie S7, which can detect single points or continuous multi-points by taking photos with the mobile phone, and the system will automatically perform AI detection with the background data after receiving the images uploaded by the mobile app. Upgrading manual inspection to AI quality inspection effectively ensures the connection effectiveness of key wiring harness connectors, avoids detection omissions caused by human factors, and improves production efficiency.
Higher standards of end-of-line testing to ensure high quality delivery
Huawei's quality control empowerment is also focused on the final assembly of vehicles. With the help of big data storage, computing and analysis, and log indexing, the production line of the Zhijie S7 adopts Huawei's self-developed data acquisition instrument, and with the help of big data storage, computing and analysis, log indexing, and other capabilities, an automation system based on big data analysis of vehicle faults has been established, which can conduct multi-dimensional tests such as vehicle electrical aging, dynamic road testing, enhanced road testing, and vehicle ORT aging. This is why Huawei has passed strict vehicle EOL inspections to ensure high standards for the delivery of vehicles.
At the same time, Huawei will also conduct ORT tests on the Zhijie S7, which is a product reliability test, using Huawei's self-developed automated test program to conduct automatic stress tests for the body, electrical system, air conditioner, and high-voltage system, simulating the reliability of the user's first 500 kilometers of the car, and eliminating various potential problems on the production line. Similarly, Huawei's two major inspections are very efficient, with a maximum of 2,000 units per day, which can generate a test evaluation report for each vehicle during testing, ensuring that the product is delivered to consumers in a healthy and efficient state.
Summary:
From manufacturing to quality inspection, we can see that Huawei's quality control empowerment of the Zhijie S7 not only ensures high quality by optimizing the process, but also ensures that each vehicle rolls off the assembly line perfectly through more stringent testing standards. What's even more commendable is that Huawei has innovatively brought in its very mature intelligent manufacturing experience and quality inspection process in the field of mobile phones, so that the Zhijie S7 has a higher level of quality control than other models. Now, Zhijie S7 has started large-scale delivery, and it is worth starting to order a car in a minute, and it is not necessary to wait for a long time.
