1. 자본시장에서 볼 때, 지능형 섀시는 자본을 끌어들이는 매력이 있습니다.

ResearchInChina의 불완전한 통계에 따르면 2024년 지능형 섀시 분야에서 수십 건의 대출이 완료되었고, 대출 금액은 30억 위안을 넘어섰습니다.

예를 들어 Trugo Tech는 2024년 1월에 시리즈 B 펀딩 라운드를 완료했는데, 이는 A 펀딩 라운드에서 불과 6개월 밖에 지나지 않은 시점입니다.

Trugo Tech는 매월 8만대 이상의 ESC 제품을 공급하는 것으로 알려져 있으며, ESC의 성숙한 개발 경험을 바탕으로 EHB/EMB 제품을 출시했습니다.

EHB: EHB는 One-Box 기술 경로를 채택하여 3.2t 미만의 차량 모델에 적합합니다. 파워 어시스트 제어, 협동 브레이크 에너지 회수, 휠 잠금 방지 제어, 차체 안정성 제어 등 30개 이상의 지능형 기능을 통합하고, 150ms 이내의 압력 상승, 180bar 이상의 최대 압력 상승, 90% 이상의 에너지 회수가 가능합니다. 에너지 회수가 가능합니다.

EMB: 액추에이터와 핵심 알고리즘을 시작으로 Trugo Tech는 건식 EMB 제품 및 관련 솔루션에 대한 사전 조사를 시작하여 국내 주요 신흥 OEM이 출시하는 모델에 대한 완전 건식 EMB POC 프로젝트를 제공할 것입니다. 2024년 테스트 차량에 탑재되고 2026년 소량 생산될 예정입니다.

2. OEM의 관점에서는 여러 섀시 기능을 확장한 것이 있습니다.

NIO 4D Comfort Pilot + Adaptive Suspension Predictive Control Solution

업계 최초로 자동차에 섀시 도메인 컨트롤러를 탑재한 OEM으로서, NIO는 2024년 1월 OTA에서 Banyan 2.4.0을 출시하고 4D Comfort Pilot(차체 수평축, 수직축, 수직축, 시간축)을 추가했습니다. 업계 최초의 지능형 섀시 시스템"이라고 주장하고 있습니다. 이 기능을 구현하기 위해서는 지능형 섀시 컨트롤러(ICC), 에어 스프링, 연속 감쇠력 제어 시스템(CDC)으로 구성된 NIO의 지능형 섀시 하드웨어 시스템이 필수적입니다.

4D 컴포트 파일럿은 차체의 지능형 주행 하드웨어에 따라 차량이 사전에 노면의 특징을 생성하고, 실시간 또는 오프라인 빅데이터 처리를 통해 그 특징을 최종적으로 섀시 도메인에 피드백하여 서스펜션 높이와 감쇠 제어 전략을 실시간으로 조정하여 운전의 편안함을 향상시키는 것을 의미합니다. 4D 컴포트 파일럿의 내비게이션 레이어는 4대의 NIO 차량(에어 스프링 CDC 장착)이 도로 구간을 통과하는 한, 4대의 NIO 차량이 이 도로 구간을 통과하는 한 생성될 수 있습니다. 후속 NIO 차량이 이 도로 구간을 통과하면 장애가 있는 레이어를 확인하고 실시간으로 업데이트할 수 있습니다.

Geely의 AI 디지털 섀시는 게걸음 모드, 탱크 회전, 슈퍼 매직 카펫 등의 기능을 지원합니다.

2024년 4월, Geely는 GEA를 기반으로 한 AI 디지털 섀시를 발표했습니다. 이 자체 개발 섀시는 도메인 컨트롤러를 통합하고 스티어링 바이 와이어, 브레이크 바이 와이어, 액티브 서스펜션, 4 륜 모터 시스템을 갖추고 있으며 3 방향(XYZ), 6 자유도의 지능형 판단을 지원합니다. 위의 하드웨어와 Geely의 AI 알고리즘 제어 시스템을 통해 AI 디지털 섀시는 다음과 같은 지능형 섀시 기능을 실현합니다. :

게걸음 모드(앞바퀴와 뒷바퀴가 같은 방향으로 구른다.)

탱크 턴

슈퍼 매직 카펫(액티브 서스펜션 조정)

단차 통과시 '제로' 충격(노면 정보를 실시간으로 인식하여 서스펜션이 타이어 높이를 능동적으로 조절)

웨이딩시 자동 조정(웨이딩 전에 프론트 서스펜션이 자동으로 들어 올려지고, 웨이딩 중에 서스펜션 높이가 실시간으로 조정됨)

사이드 액티브 디펜스(측면 충돌의 위험이 있을 때 차체 한쪽이 빠르게 상승하여 충돌로 인한 손상을 줄임)

Geely의 AI 디지털 섀시는 단 4밀리초(인간의 극한 반응의 25배)만에 반응하여 극한 상황에서 "위험 회피에 대한 차량 제어"를 가능하게 하며, Geely의 AI 디지털 섀시는 늦어도 2025년까지 대량 생산되어 Geely Galaxy, Lynk & Co. 등에 탑재될 것으로 알려졌습니다.

중국의 자동차 산업에 대해 조사분석했으며, 승용차용 지능형 섀시 컨트롤러 및 섀시 도메인 컨트롤러 산업과 개발에 관한 정보를 제공하고 있습니다.

Chassis controller research: More advanced chassis functions are available in cars, dozens of financing cases occur in one year, and chassis intelligence has a bright future.

The report combs through the development and application of passenger car chassis controllers and chassis domain controllers, and interprets the status quo of the industry from three perspectives: suppliers, OEMs, and capital.

1. From the perspective of the capital market, intelligent chassis has an eye-catching ability to attract capital.

According to incomplete statistics from ResearchInChina, dozens of financing cases have been completed in the field of intelligent chassis in 2024, with the financing amount exceeding RMB3 billion.

For example, Trugo Tech closed a Series B funding round in January 2024, only 6 months away from its A++ funding round, thanks to the capital market's sustained attention to intelligent chassis and Trugo Tech's own technical strength.

It is known that Trugo Tech has supplied over 80,000 ESC products monthly. Based on the mature development experience of ESC, Trugo Tech has deployed EHB and EMB products.

EHB. The product adopts the One-Box technology route and can be matched with <3.2t vehicle models. It integrates more than 30 intelligent functions such as power assist control, coordinated braking energy recovery, wheel anti-lock control and body stability control, and supports multi-sensor fusion. It features pressure build-up in less than 150ms, and the maximum pressure build-up greater than 180bar, and can recover over 90% of energy.

EMB. Starting from actuators and core algorithms, Trugo Tech has started pre-research on dry EMB products and related solutions, providing full dry EMB POC projects for the models to be released by domestic leading emerging OEMs. The EMB products are expected to land on vehicles for testing in 2024, and come into small volume production in 2026.

2. From the perspective of OEMs, some have expanded multiple chassis functions.

NIO 4D Comfort Pilot + Adaptive Suspension Predictive Control Solution

As the first OEM in the industry to install chassis domain controllers on cars, NIO released the Banyan 2.4.0 via OTA in January 2024, adding 4D Comfort Pilot (the horizontal, vertical and longitudinal axes of the body and the time dimension). NIO claims that it is "the industry's first intelligent chassis system powered by AI technology". Enabling the functions is inseparable from NIO's intelligent chassis hardware system composed of intelligent chassis controller (ICC), air spring and continuous damping control system (CDC).

4D Comfort Pilot means that the vehicle generates road surface features in advance according to the intelligent driving hardware on the body, and then through real-time or offline big data processing, the features are finally fed back to the chassis domain to adjust the suspension height and damping control strategy in real time to improve driving comfort. The navigation layer of 4D Comfort Pilot can be generated as long as four NIO cars (equipped with air springs + CDC) pass by on a road section. Subsequent NIO cars passing through this road section can confirm the bumpy layer and achieve real-time updates.

Geely's AI digital chassis supports such functions as crab walk mode, tank turn and super magic carpet.

In April 2024, Geely released an AI digital chassis based on the GEA. The self-developed chassis integrates domain controllers and is equipped with steer-by-wire, brake-by-wire, active suspension and four-wheel motor system, supporting three-way (XYZ), six-degree-of-freedom intelligent decision. Supported by the above hardware and Geely's AI algorithm control system, the AI digital chassis can enable the following intelligent chassis functions:

Crab walk mode (front and rear wheels roll in the same direction)

Tank turn

Super magic carpet (active suspension adjustment)

"Zero" impact when passing over bumps (real-time perception of road information; tire height adjusted by the suspension actively)

Automatic adjustment for wading (the front suspension is automatically lifted before wading, and the suspension height is adjusted in real time during wading)

Side active defense (when there is a risk of a side collision, one side of the body will quickly rise to reduce the damage caused by the collision)

Geely's AI digital chassis makes a reaction in just 4 milliseconds (25 times faster than the human extreme reaction), enabling "automatic vehicle control for risk avoidance" in extreme conditions. It is known that Geely's AI digital chassis will be mass-produced and installed in Geely Galaxy, Lynk & Co and other products by 2025 at the latest.

3. From the prospective of suppliers, some OEMs in China have made significant progress in chassis domain controllers in 2024.

In research and development of cooperative intelligent chassis controllers, foreign players benefit from their technical expertise and first-mover advantages in traditional automobiles. Some foreign suppliers already have some mature products, such as Bosch's integrated vehicle dynamic control system and ZF's cubiX chassis integrated controller. Chinese parts suppliers have started R&D of cooperative intelligent chassis controllers since 2000, and quickened their pace in recent years, gradually narrowing the gap with international giants.

Currently, there are three main types of players in China that are developing chassis domain controllers:

First, companies that focus on chassis domain controllers, such as MXD. They can provide full-stack services from hardware platforms to application layer, but they have a short history and limited development capital reserve.

Second, Chinese chassis suppliers that deploy one or more components for brake-by-wire, steer-by-wire or suspension-by-wire. They have mature chassis development experience and have initially achieved mass production of actuators. Representatives including Global Technology, Tongyu Automobile and Trinova often have profound technical expertise in a single actuator, but still face obstacles in horizontal expansion for domain control solutions.

Third, traditional automotive electronics companies represented by Jingwei Hirain. They often have mature development experience in domain controllers. For example, Jingwei Hirain has deployed products in the body domain, driving domain, and chassis domain, and participated in the R&D and supply of chassis domain controllers for NIO, with certain mass production experience.

MXD

In April 2024, MXD debuted at the Auto China with VCC 1.0, its first-generation Lingkong Series chassis domain controller which integrates CDC, ECAS, EPB and onboard IMU and realizes the function of dual-control EPB through the EPB module. It is known that VCC 1.0 has been designated by JAC.

In July 2024, MXD announced that it would integrate its self-developed rear wheel steering control on the first-generation chassis domain controller, providing the market with VCC 1.5, a new chassis controller with software and hardware decoupled.

Tongyu Automotive

In July 2024, Mr. Shu Qiang, founder, chairman and general manager, said that Tongyu Automotive had released its first-generation chassis domain controller which can enable integrate control of braking, steering, suspension, parking, driving and other systems, and decouple the high-level functional algorithms related to vehicle dynamic performance in the original components (VDC, TCS, etc.) from the braking system and place them in the chassis domain controller instead. In addition, the solution supports dual MCU redundancy and integrates a combined positioning module. The two MCUs and CAN form vehicle architecture ring network redundancy. In terms of hardware redundancy, key power supplies, sensors, actuators, and communications are redundant.

As early as March 2024, Tongyu Automotive formed a partnership with C*Core Technology. They will create a localized automotive electronic chassis-by-wire controller solution.

Jingwei Hirain

In June 2022, NIO announced China's first full-stack self-developed suspension control system equipped with a full-stack self-developed intelligent chassis controller (ICC). It was first available to the production vehicle ET7. Jingwei Hirain participated in the R&D and production of this domain controller.

In February 2024, Jingwei Hirain started mass production of its full-stack self-developed chassis domain controller. So far, it has mass-produced controllers, underlying software, air springs, suspension algorithm modules, and realized functions such as welcoming and seeing off, active prediction, and magic carpet suspension. Jingwei Hirain's full-stack self-developed chassis domain controller has the following Features:

It integrates damping control, air spring height control and other functions, and simplifies the chassis control system

It can also integrate rear wheel steering, electronic stabilizer bars, steering column position control, engine mounting, etc.

In the combination with intelligent actuators, the chassis domain controller with enough computing power reserved can integrate longitudinal, lateral and vertical control functions of vehicles, such as steering, braking and suspension to perform high-level cooperative chassis control and vehicle motion trajectory control.
