Cars move towards the smart era, with body electronics injecting soul

In 2023, the automotive electronics market may face challenges such as the decline in macro consumer demand and the convergence of innovation paradigms. However, the new four modernizations represented by electrification and intelligence are still continuing to deepen. Under the new industry trends, business cooperation and downstream orders are both declining. In a period of high prosperity.

Standing at a new development node where opportunities and challenges coexist, the 2023 Automotive Electronics Carnival organized by Xinshiye in conjunction with the Munich Shanghai Electronics Show and sponsored by Anxiyi has set up four major themed roundtable talks, bringing together many leading companies, industry leaders and technical experts , focusing on the innovation boom surging under the intelligent transformation of automobiles, deconstructing the new development paradigm of the automobile industry value chain, and creating a future-oriented "automotive electronics ecosystem".

Body electronics technology makes cars “alive”

Automotive Electronics Carnival Roundtable Talk 

On July 11, the afternoon session of the Automotive Electronics Carnival Roundtable Talk was themed "Body Electronics Technology Makes Cars Come Alive", with Zhang Jian, Asia Pacific Application Engineering Director of NI Semiconductor Division, as the special host. , and invited 5 big names to share their insights on body electronics technology through keynote speeches, and interact deeply with practitioners present.

Founded in 1976, NI is committed to developing automated testing, measurement and calculation solutions based on open software platforms. From " virtual instrument technology" to opening up the era of "software definition" in the field of test and measurement, to building a more complete enterprise-level data link, NI has become Technology connector and innovation driver for different industries and applications. NI has been deeply involved in China for 23 years. Its open software platform and rich hardware resources have also formed a complete technological ecosystem in China, which is widely used in next-generation communications, semiconductors, commercial aerospace, transportation, energy, medical, consumer electronics, industrial electronics, etc. field.

01. Product layout and market analysis of automotive grade devices

At the forum, Qorvo Sales Director Huang Jing delivered a speech titled "Automotive Grade Device Product Layout and Market Analysis" and discussed with the guests the new layout of the automotive industry and the role of Qorvo's automotive grade devices.

Qorvo Sales Director Huang Jing

Huang Jing introduced that Qorvo has deeply cultivated and presided over the field of radio frequency . With the acquisition, integration and reorganization of some product lines in recent years, Qorvo has provided customers with a multi-dimensional product category and a complete set of solutions. For example, car body applications include communication modules, V2X, UWB, and power control management, as well as the underlying architecture that supports the design of these functions. Qorvo has a layout.

For example, in the field of sensors, there is a risk of water intrusion into the gaps between certain buttons on the car body. These buttons can be replaced by a seamless flat surface, and then the sensor can sense the pressing force on the flat surface and realize different functions according to different strengths; another example is the field of UWB, in which biological organisms in the car The sensing function can alert car owners by sensing breathing to prevent children and pets from being forgotten in the car. Qorvo can provide a variety of solutions to achieve these functions.

When talking about supply chain management with the host, Huang Jing introduced that Qorvo has two methods. The first is to achieve end-to-end independent control as much as possible and avoid risks through independent control; the second is to keep up with upstream and downstream partners, communicate closely with the industry, build more cooperative relationships, and manage the supply chain in advance, through These two methods maintain stable production capacity.

02. Regional controller builds vehicle interconnection

He Beiwei, a senior application engineer at STMicroelectronics, shared " Regional Controller -Building Vehicle Interconnection" with everyone. As the automotive electronic and electrical architecture gradually evolves to a regional architecture, ZCU, as a bridge between the automotive central computing unit and edge control nodes, plays an important role in the vehicle network. This speech mainly introduced the development trend of zone control architecture, ST's ZCU solution and the advantages and characteristics of related products involved.

Beiwei He, Senior Application Engineer at STMicroelectronics

The speech pointed out that the electronic and electrical architecture of automobiles is gradually evolving from a distributed architecture to a regional architecture, that is, the central computing unit serves as the control center, the sensors and actuators serve as the underlying nodes, and the regional controller (ZCU) serves as the connection between the two. bridge. The regional architecture simplifies the vehicle system architecture, while reducing weight and cost, and can provide more refined power distribution and control for the entire vehicle.

For the ZCU solution, this speech introduced STMicroelectronics’ latest research and development product, the Stella series MCU with arm Cotex R52 core . This series of MCUs uses the latest PCM technology to replace the original Flash technology, which greatly improves the efficiency of MCU software refresh and is non-trivial. Lost storage utilization. Moreover, this series of MCUs supports hardware virtualization functions. STMicroelectronics has comprehensive product coverage for ZCU solutions. This solution covers most of customers’ ZCU application needs and helps accelerate customer product development.

Based on the development trend of ZCU, He Beiwei introduced during communication with the host that the regional architecture is a big change compared to the distributed architecture in the past, and its implementation needs to be gradually promoted. However, regional architecture is the current development trend in the industry, and car companies are following suit. I believe that in the near future, everyone will see models with this architecture launched.

03. Carbon is the future, testing comes first

Ms. Xiang Jiaying, China Marketing Director of Tektronix Technology (China) Co., Ltd., introduced in the speech "Carbon is the Future, Testing First" that Tektronix, as an old technology company that has been deeply involved in the testing industry for more than 70 years, has always been an endowment of cutting-edge technology in the industry. Those who are capable. Help new energy vehicle companies solve problems such as SiC testing and electric drive product development and testing under 800V electric drive platforms.

04. Abandon price involution and how to find differentiation in the field of automotive semiconductors

The theme shared by Xu Wei, Vice President of Marketing Department of Jiangsu Diao Microelectronics Co., Ltd. is "Abandoning price involution, how to find differentiation in the field of automotive semiconductors?" 》. With the advent of automobile intelligence and electrification, the body structure has undergone earth-shaking changes. Abandoning pure price involution, how to find differentiation is an eternal topic. Xu Wei pointed out that the differentiation of automotive chips has multiple dimensions: reliability, better cost performance, products that better meet customer system applications, etc.

Xu Wei, Vice President of Marketing Department of Jiangsu Diao Microelectronics Co., Ltd.

Xu Wei believes that automotive chips can be divided into four grades from bottom to top: cost-effectiveness, reliability, problem solving, and trump products. From the first to the fourth grade, products gradually break away from price involution, and at the same time quality and requirements are gradually improved. , the response they receive in the market and the value they create are naturally different.
