There is a generally accepted view in the automobile manufacturing industry that the latest manufacturer can be the most advanced, because it can be equipped with the most advanced hardware and software manufacturing equipment, and adopt the most advanced manufacturing management process, provided that it has a high enough manufacturing standard system, enough and efficient allocation of human resources and capital investment. From this point of view, the new force players who are labeled with PPT have the opportunity to build high-quality cars, but the opportunities are not equal, because the resources are limited. Among the existing 20 plus players, Aichi car is a little mysterious, but it has a well-known German background - its founder, R & D and manufacturing team are almost the same German Volkswagen Audi origin. What kind of electric cars will such a group build? Q: you went to Shangrao to participate in the test drive and factory visit of Aichi U5. Please talk about the impression of U5, which will be on the market at the end of this month. Many people pay attention to it. A: the overall outline of this car is undeniable. From all angles, the proportion and shape are quite harmonious. The body lines are sharp and delicate, belonging to the strong and dynamic style. The interior design is very simple and smooth, looks clean and clean, typical of the new energy vehicle style. In driving experience, I have driven more than 180 kilometers, including a large section of mountain road, small town crowded road and highway. I have no doubt that this is a German car. The brake, steering, turning and high-speed are all very easy and stable, that is to say, to adjust the energy recovery intensity to enter the touch screen menu is more troublesome, and the maximum recovery intensity is not enough; the voice interaction system is very good, and communication starts It's very smooth. QQ music resources are also very rich, which is what I particularly like. Unfortunately, the L2 level function of the test drive has not been opened and can't be experienced. In terms of manufacturing technology, the car's body seams and scale effect can't be found, and the interior assembly is also quite accurate. It's completely the way of Volkswagen, which makes me a little disappointed, a person who likes to pick up problems. Q: the same compact SUV, U5 is much more expensive than G3 and Xiaopeng. What do you think? A: the U5 is positioned at a + level, between the compact Xiaopeng G3, Weima Ex5 and the medium-sized ai'an LX and 600, and the price is the same. Specifically, the wheelbase and body size are the same. It is 235, 2 cm wider than G3 and Ex5. The rear suspension is multi link, which is in line with the AI LX and Tang ev600, and the endurance mileage is 100 km more than G3 and Ex5. These won't be free lunches, of course. I am very impressed that the NVH of U5 is quite good, reaching the level of a higher-level car; there is a lot of space in the rear seat, after adjusting the front seat, I (1.82M) sit in the rear seat, there are two and a half fists between the knee and the front seat, which is completely the level of the Chinese SUV. Overall, U5's own performance, parameters, space, configuration, technology, etc. are matched with its product positioning and price positioning. Product size, configuration and price are inserted between compact and medium-sized competitors to play differentiation or dislocation competition. Rx, ES, Tiguan L and oncoway are all the same, and they are the main sales models of their own brands. How will U5 sell? It's worth looking forward to. Q: you just mentioned that the manufacturing process of U5 is completely the way of Volkswagen. What is it like to visit the "super smart factory" of Acer? A: the first feeling is that the factory is large enough. The first phase of 150000 units has been completed and 4 billion has been invested. In terms of financing, Aichi's voice is the smallest, but it's really surprising that so many things have been put there. The second feeling is that this is a factory of Volkswagen. Due to the time, we only visited the stamping workshop, welding workshop and quality center, and saw the classic German Volkswagen manufacturing process, and the equipment is quite advanced. The welding workshop adopts a 6700 ton 5-sequence servo stamping line, which is totally closed and high-speed automatic, and can be pressed 16 times per minute continuously. In contrast, Beijing Benz adopts 6000 ton 5-sequence closed automatic stamping line, with the production beat of 13 times per minute at most, while the general stamping line is 4 or 5 times per minute. The manufacturing standards here copy the German mass system. For example, the whole vehicle matching requires that the DTS of standard German system be matched, and the key matching should follow the standard of "± 0.5" mm. However, Aichi did not completely copy the manufacturing process of Volkswagen in Germany, but had a number of innovations on this basis. For example, it pioneered the "positioning method of body online Aurora measurement", "door assembly system of artificial intelligence machine vision" and "efficient measurement system of dual track, dual zone and multi station lidar", which further improved the accuracy and production efficiency of the products. AGCO has relevant intellectual property patents. This kind of innovation can only be achieved by the local automobile manufacturing elites who have been in the joint venture of Volkswagen for many years, deep-rooted, experienced and creative. The premise is, give them a chance. A top German car maker also came to visit Aichi factory. Due to the late flight, I missed him. According to his words: like crazy people, Erich has solved the problems in the joint venture. It's really a pioneering work. We must apply for an international patent, which is worth learning from the joint venture. Q: "super smart factory" should be related to AI Artificial Intelligence, big data and Internet of things applications. Other new car building forces claim to have a leading edge in this area. What do you think? A: I haven't been to any of the other new power factories, but I've read relevant information. After listening to and seeing Aichi, my feeling is that it reminds me of the new Dadong factory which was put into production two years ago, known as "China's first industrial 4.0 complete vehicle factory". The industrial 4.0 elements with the main characteristics of big data application and Internet of things are everywhere (see "how to build the most" accurate "BMW car?"? 》）。 For example, for the whole vehicle and parts, Aichi establishes a complete dimension monitoring system of single piece body whole vehicle by scanning points, lines and surfaces, from single piece to assembly, to the whole vehicle to form a complete quality data chain, the quality pre-warning mechanism based on online laser measurement big data analysis, the big data management through all production links, etc. are all familiar. But a senior manager who has been to BMW's new Dadong factory said that compared with BMW, the digital intelligent management here is the second generation. Of course, as a third party, to recognize this conclusion, a lot of comparison needs to be done. I have a basic judgment for some new car building forces to claim that their factories have a leading edge in "intelligent manufacturing". To put it bluntly, one new car building force enterprise has enough car building information, which uses artificial intelligence, big data and the Internet of things as important tools, and the other lacks car building information, which is really in the application of artificial intelligence, big data and the Internet of things I'm more proficient in it. The result will not be the same. Which car do you think is more reliable? However, there are two main purposes for the application of artificial intelligence, big data and the Internet of things in automobile manufacturing: one is to create the "most accurate" automobile, to maximize the realization of vehicle design standards; the other is to minimize defective products and waste in the production process, while improving efficiency. The former is related to the quality of automobile, the latter is related to the cost and price of automobile, which are the two key factors for the survival and development of automobile enterprises. U5 is the most accurate electric vehicle compared with its main rivals, and ultimately the market has the final say.
