DUBLIN–(BUSINESS WIRE)–The “Global and China Automotive Gateway Industry Report 2023” report has been added to ResearchAndMarkets.com Dedication.
Automotive gateway research: Integrated gateways have become an important trend in partitioned architecture.
Automotive gateways are core components in automotive electronics/electrical architecture. As the hub of the vehicle network, it realizes functions such as data transmission, safety prevention and control, and remote diagnosis.
As the E/E architecture evolves from a distributed domain architecture to a centralized domain architecture, the gateways also change accordingly.
Traditional CAN gateway in distributed architecture
Phase 1: Distributed ECU architecture means many single-function ECUs providing hardware/software solutions. These functional ECU clusters (e.g. power, chassis, body, safety and IVI systems) are grouped together and connected via conventional bus systems (e.g. CAN, LIN or FlexRayT). While sensors and actuators are connected directly to the ECU, interaction between domains is achieved through a CAN gateway.
Central gateway in domain centralized architecture
Stage 2: The “domain” of the domain controller generally refers to the functional domain, which is divided into: powertrain, chassis control, body control, entertainment system (cockpit) and ADAS. Systems in these areas are still interconnected using CAN and FlexRay communication buses.
For inter-domain communication, Ethernet with higher performance is used as the backbone network for information exchange. In this architecture, a central gateway is required for inter-domain communication. This gateway allows data exchange with the OEM vehicle cloud and is therefore considered a “service gateway”.
Distributed gateways in zone architecture
Phase 3: In the Availability Zone architecture, the central gateway will evolve into an HPC or central computer, and the domain gateway will evolve into an Availability Zone gateway.
The gateway is not only responsible for the routing of the in-car network communication bus, but also for more complex functions such as data correlation and processing between safety domains and functional domains (e.g. powertrain, chassis and safety, body control, IVI). and ADAS) through the MCU+SoC computing platform. The biggest benefit of this architecture is the significant reduction in wiring harnesses, which reduces weight and cost by approximately 30%.
Currently, gateways are in the transition stage from centralized gateways with domain centralized architecture to distributed gateways with partitioned architecture.
In response to the general trend of cross-domain integration, many gateway chip manufacturers have proposed their own solutions. For example, the S32G3 network processor released by NXP at the end of 2021 has the characteristics of real-time processing capabilities, service-oriented high-performance computing capabilities, cross-domain integration, high-performance security processing, etc., and provides complete software development tools to meet the needs of various new automobiles. Development requirements for E/E architecture: service-oriented gateways, on-board computers, domain controllers, regional processors and security processors.
The NXP S32G3 network processor will be mass-produced in February 2023 and will be installed on the GAC Hyper GT for the first time in April 2023.
The G9H chip SemiDrive launched in July 2022 is mainly used in next-generation high-performance central gateways, vehicle-mounted computing units, cross-domain controllers and other scenarios. In addition to the body network interface, G9H also supports video input/output interfaces, including 1-channel MIPI DSI and 2-channel MIPI CSI. Coupled with PowerVR’s high-performance 3D GPU, G9H can integrate 3D clustering, DMS and other functions into the central gateway, further reducing the BOM cost of the system.
Gateway vendors are gradually moving from stand-alone gateways to integrated gateways. The main integration methods include the integration between the gateway and the body domain, the integration between the gateway and the regional controller, and the integration between the gateway and the central computer. In 2023, many vendors released integrated gateway solutions.
For example, UAES released a cross-domain central computing platform product for the next generation E/E architecture in April 2023. The solution integrates central gateway, body control, power and other functional domains, with underlying software and middleware development support provided by Neusoft Reichi.
Another example is the physical zone control unit (ZCU) and central computing platform (CCP) released by Jingwei Hengrun in May 2023:
ZCU: Integrate vehicle power distribution function, partition gateway routing function (100M Ethernet, CANFD, LIN, etc.), body comfort domain, new energy power domain, part of the chassis domain, as well as air input and output signal acquisition and control air conditioning and thermal management.
CCP: Integrate centralized gateway, body and comfort control, new energy vehicle power control, air conditioning and thermal management, vehicle management, full data collection, OTA updates, SOA services and other functions.
At present, both of the above products have been developed, tested and produced in small batches. Production delivery is expected in 2023. Among them, CCP has been put into mass production and is supporting four domestic mainstream car companies.
As gateway chips and integrated gateway technologies mature, OEMs are racing to implement their “quasi-centralized” architecture solutions on mass-produced models, most of which will be launched in the 2022-2024 period.
