Under the four modernizations of the automotive industry, how can semiconductor manufacturers lead car companies to win the competition?

The traditional automobile industry has ushered in a century of great changes: Four new trends “ACES”: Autonomous, Connected, Electrified and Services are reshaping the overall pattern of the automobile industry.

From a technical perspective, automobiles have evolved from traditional mechanical products to intelligent products controlled by Electronic information systems. Automotive electronics have played a vital role in the transformation of the automotive industry. The innovation of automotive electronics has become an important driving force for innovation in the automotive industry. strength.

Under the four modernizations of the automotive industry, how can semiconductor manufacturers lead car companies to win the competition?

Relevant agencies predict that in the future, there will be a 20-fold increase in semiconductor demand for each car, and the proportion of electronic products in the car assembly will continue to increase, exceeding 50%. At the same time, compared with traditional power vehicles, the market share of electric vehicles and hybrid vehicles is expected to reach 20% of the overall automotive market.

Under this trend, major global auto companies and suppliers are actively deploying in the field of automotive electronics following the trend.

Recently, Allen Chen, MPS’s global automotive product director, introduced the company’s core automotive product development strategy and the latest technological developments to the media, analyzed the opportunities and challenges that MPS faces in this change, and what innovations it will lead the automakers to Win the “ACES” competition.

Under the ACES trend: ECU transition to DCU

At present, most car companies are still in the stage of distributed architecture, and a small number of car companies have the concept of domain division. The current vehicle control system is based on ECU (Electronic Control Unit), and each function corresponds to one or more ECUs, such as heating device ECU, multimedia system ECU… and so on.

With the gradual improvement of the electronic level of vehicles, there are more and more ECUs in the car, but the scattered ECUs will bring many problems to the car design. Allen said that, for example, each ECU is a separate array, or a strong central gateway is needed to coordinate. In addition, it also increases the complexity of car routing and increases the cost of car manufacturing.

Therefore, how to ensure the optimization of data processing and network security in complex lines has become a difficult problem. Using fewer DCUs (domain controllers) to control the entire vehicle’s ECUs and sensors is gradually becoming the current evolution trend of automotive electronic and electrical architecture. The electronic process of automobiles will move from component-oriented to a centralized system-oriented era.

DCU breaks the traditional way of thinking. Compared with ECU’s focus on unique functions, DCU’s goal is aimed at integration, security and core computing, which directly refers to the theme of ACES. The logic of DCU is to divide the entire vehicle into several domains such as powertrain, vehicle safety, body electronics, smart cockpit, and smart driving according to the functions of electronic components, and then use a core processor with stronger processing capabilities to perform processing on each domain. Control, to achieve the purpose of replacing the current distributed automotive electronic and electrical architecture.

DCU has improved the integration of vehicle functions, and the design of software and hardware has more possibilities for separation. The role of a single ECU is weakened, complex data processing and control functions are unified in the core processor, and the ECU is more of executing DCU commands. At the same time, the sensor module no longer needs to correspond to a specific ECU, so the parts can be standardized production.

Under the new situation of the automotive industry, the role of the supply chain is changing

The current automotive electronics industry industry chain can be divided into three levels: the upstream of the industry chain is mainly automotive electronic components and parts manufacturers, responsible for the production of components and parts; the middle of the industry chain is mainly based on system integrators and modules The design, production and sales of customized functions are mainly aimed at the integration of upstream parts and components, and provide solutions for a certain function or a certain module; the downstream of the industrial chain is the entire vehicle link, which is led by car companies, and is in the industrial chain. Have higher bargaining power.

However, this trend is changing with the development of the new situation in the automotive industry. Traditional Tier 1 and OEM manufacturers have begun to integrate, stripping off the traditional powertrain department, and separating the company team that specializes in ACES. At the same time, different companies cooperate on the same platform to solve technical problems together and enjoy the results brought by technological progress.

During this process, the role played by semiconductor manufacturers in the entire supply chain has undergone important changes. Regarding the current development trend, Allen believes that auto manufacturers are increasingly relying on semiconductor manufacturers, and they need more advanced technology from semiconductor manufacturers, as well as providing The direct functional and reliability test results they need help automakers have enough confidence to bring next-generation products to the market.

It takes a lot of money and energy to achieve better results in the fierce ACES competition. Many new technologies require huge capital investment, the production cycle of products is getting faster and faster, and products in different fields are becoming more and more integrated, and the busy line is gradually getting longer.

Therefore, semiconductor companies including MPS have obtained huge opportunities from market growth, but the backside of the opportunities is also full of challenges.

Regarding the challenges faced by semiconductor manufacturers, MPS summarizes the following points from the product level:

The first point: easy scalability. Ease of scalability is very important for both the company and its customers. Customers hope to have a product that can be applied on their different platforms. Regardless of the size of the platform, they can have a trusted platform solution to help them solve the problem. need.

The second point: rapid design, verification and configuration. Fast product iteration cycle is one of the challenges facing OEMs and Tier 1. If there is a solution, its design, verification, and configuration can be completed in a short time, so that customers can have more advantages in the ever-changing competition.

The third point: safe and reliable. To ensure the safety and reliability of the product, there is no single point of failure.

Fourth point: tolerance in harsh environments. It is required that car manufacturers and Tier 1 can provide solutions with strong tolerance.

In the ACES competition, how does MPS obtain the magic weapon to win?

Allen said that in the face of the above challenges, in order to help automakers achieve their ACES goals, MPS will fully consider the “killer” features of a given product, unify product development routes and the overall chip ecosystem, and carefully design with higher security. Productivity, scalability and reliability.

Up to now, MPS has been deeply involved in the automotive electronics industry for more than 8 years. It has more than 500 types of automotive-related products and has delivered more than 700 million automotive products. It has the ability to help customers build safety thinking from scratch and help customers solve problems. Safety related issues in the design.

Regarding the characteristics of MPS products, Allen said that in addition to the meticulous carving of a single IC, we are now adopting more of the “Power Subsystem” model, that is, the design of the power supply subsystem.

This power subsystem is designed for ADAS modules. It is a combination of more than six different ICs. Each subsystem can operate harmoniously. Some of the ICs are power management products based on MPS advanced process technology, aiming to provide ultra-high power density. . Other ICs are analog products dedicated to timing control and voltage monitoring.

In this kind of power subsystem, it is necessary to consider not only the typical functions of each IC, but also how each IC and each device work together with other devices. MPS’s “power subsystem thinking” is being verified in cooperation with third-party evaluation agencies to help customers not need to focus on a single IC, and can speed up the design cycle through the power supply scheme of the entire subsystem. It can be seen that MPS has actually expanded the range of its automotive application products from the best DC/DC power management products to the precision analog field.

“In the ACES competition, MPS helps customers quickly develop safe, reliable, and scalable solutions with unique insights and keen insights, provides customers with more complete solutions, and helps customers solve the challenges they face.

On the other hand, MPS has invested in many test centers, which are widely distributed in the United States, Europe, China, etc., and have a mature team of engineers in each region to help customers test and solve problems, ensuring the stability and durability of the system design . “As for MPS’s competitive advantage, Allen added.

The wave of automotive ACES intelligence is sweeping, and the wave is full of temptations and challenges, and various manufacturers are eager to try.
