Traditional automobile investment internet platform

High-end Interview with Guangzhou Auto Show 2021119 Guangzhou International Automobile Exhibition opened with the theme of "New Technology, New Life". Under the double challenges of epidemic situation and chips, mainstream automobile brands gather in Guangzhou to paint a vision for the future intelligent and electrified transportation, and also inject confidence and vitality into the sustainable development of China automobile industry.

At this Guangzhou Auto Show, Nezha Automobile launched the full-stack self-developed mountain and sea platform and the brand-new coupe Nezha S based on this platform, becoming another domestic automobile enterprise with full-stack self-developed platform capability.

Zhang Xu, Assistant to President of Nezha Automobile and Dean of Automotive Engineering College, visited Easy Car and Automobile Production Network. Zhang Xu, a senior expert in automobile R&D, shared with us the technical R&D ideas and layout behind the development of "Shanhai Platform" by Nezha Automobile.

Born in the traditional automobile industry, he also said that it is very interesting to accept new changes in the field of intelligent networking while accumulating traditional experience in production and research. It's like Nezha Auto, a brand with new power. On the one hand, it has the speed and efficiency of the new era, on the other hand, it also has awe and vigilance against traditional manufacturing. When the two are combined, a changed Nezha car appears.

The following is an interview record:

Automobile sankei: First of all, please introduce the key products of Nezha Automobile at this year's Guangzhou Auto Show?

Zhang Xu: This time, we brought the B-class digital electric coupe Nezha S,150,000-class Nezha U Pro, 70,000-class Nezha V Pro based on "Shanhai Platform", Nezha V Witch Edition based on female users, and Mengwa's first electric car Nezha Magic Boy.

Automobile production: The theme of this year's Nezha exhibition is "Equal rights in science and technology, wisdom in mountains and seas". How to understand the meaning of these eight words?

Zhang Xu: The vision of Nezha brand is to make high-quality intelligent electric vehicles within reach and let users enjoy the advantages of intelligent travel. "Mountain" represents vastness, which is our attitude towards the future. "Wisdom" represents the main features of Shanhai platform, and "enjoyment" means that we hope ordinary users can also experience intelligent electric vehicles, which is also the embodiment of equal rights in science and technology and the positioning of Nezha brand.

Automobile Production: At Guangzhou Auto Show, Nezha released a full-stack self-developed mountain and sea platform. What are the main features and advantages of this platform?

Zhang Xu: This platform integrates high safety, high expansibility, high intelligence and environmental protection, and it is also an intelligent and safe car platform developed by Nezha. Because the user's demand is fast and changeable, in order to respond to the user's demand quickly, we developed this "mountain and sea platform".

Security includes passive security, network security, functional security and battery security. We also cooperated with 360 to apply 360 car brain to fully protect user privacy and car system security, which is also an area that users are very concerned about at present.

High scalability helps us to improve efficiency, reduce costs and continue iteration. For example, our chassis structure can meet the different requirements of curve performance and straight performance. In curve performance, it is equipped with double wishbone+five-link suspension, in straight performance, it is equipped with air suspension, and in straight performance, it is equipped with dual-motor four-wheel drive model, which can enter the zero-second club. Based on the development of mountain and sea platform, the universal rate of parts can reach 80%, the development time can be shortened by 8 months, and the cost can be reduced by 30%-40%.

High intelligence means that we have the technical ability of intelligent driving and intelligent cockpit. In the future, we will gradually realize full-scene intelligent assisted driving on high-speed sections, low-speed sections and city records. By 2025, the Shanhai platform will evolve to the central domain integration architecture, realize the complete decoupling of vehicle actuators and computing resources, and seamlessly connect with the cloud-based large-scale supercomputing platform. This will greatly improve our technical ability, and the function to meet the needs of users will be realized faster.

In addition, Shanhai platform has an advanced and highly integrated battery structure, and uses green materials to enhance environmental protection.

Automobile Production: Nezha S should be an epoch-making product for Nezha. What do you think is its greatest advantage or core competitiveness around this product?

Zhang Xu: First of all, the coupe is unique in shape and high in safety. We spent a lot of energy on the mountain and sea platform. High-strength steel is widely used in the car body, and the proportion of hot-formed steel is close to 30%. Even some key areas use cast aluminum technology to make the fuselage lighter and stronger. In addition, we also provide an extended range version, with a cruising range of 1 100 km, and the cruising range of pure electric vehicles has reached 800 km.

In terms of intelligent driving, we can achieve L3-level automatic driving and reach L4 in some scenes, which is also a relatively advanced level in the industry. With the addition of 360, the car networking security system of our vehicles has been greatly improved.

In terms of battery safety, it mainly solves the anxiety of users about fire. We manage the battery with a health model through big data, which can monitor the health status of the battery in real time and realize early warning and reminder. In addition, we also applied integrated heat pump, which can reduce energy consumption, improve efficiency and save energy by 20%.

Automobile sankei: Just now, you also told us a lot about Nezha's investment in technology, so we know that there are engineering research institutes and intelligent research institutes in Nezha. What is the mode of division of labor and cooperation between the two institutes?

Zhang Xu: Engineering Research Institute is mainly responsible for vehicle research and development, including body and three electric technologies, and Intelligent Research Institute is mainly responsible for intelligent driving and technology development. Of course, the technical platform will eventually fall on vehicle development, so we also have a close cooperative relationship. The reason why it is divided into two research institutes is also in line with Nezha's flat management enterprise structure, which can achieve faster response speed and faster decision-making. At the same time, because the technical development should be more forward-looking, the production and manufacturing of vehicles should ensure the cost and the feasibility of landing, so separating the two is also to give full play to their respective advantages.

At present, the team of our engineering research institute has about 600 people, and it will be expanded to 1 000 people next year. This is also the characteristic of Nezha Automobile, that is, the investment and attention to R&D is very high.

Our founder also came out of the traditional automobile industry, so we think that the technical research and development and manufacturing of vehicles are still very important links, and the intelligent driving experience brought by electric vehicles is also a dynamic field and very interesting. A combination and change.

Combining traditional experience with the efficiency of keeping pace with the times is the accumulation and characteristic of Nezha.
