In the past few decades, the automotive industry has experienced a transformation from simple fuel power to electrification and intelligence. In this process, the functions and application scenarios of smart cars continue to expand, which has a significant impact on the number and complexity of on-board control units (ECUs). Today, many cars are equipped with dozens or even hundreds of ECUs to meet various functional requirements.
With the development of technology and changes in market demand, the automotive electronic and electrical architecture is also constantly evolving. In the past, automobiles adopted a traditional distributed architecture, that is, each ECU worked independently, and each was responsible for some functions. However, this architecture is incapable of dealing with complex requirements. Therefore, more and more cars begin to adopt a domain-centralized architecture, that is, to centralize some or all functions on one or several ECUs for management and control.
The complex and rapid changes in the requirements of the control system have promoted the evolution trend of the automotive electronic and electrical architecture from the traditional distributed architecture to the domain centralized architecture.
The advantage of domain-centralized architecture is that it can improve the overall performance, reliability and security of the system. By integrating related functions in one or several ECUs, communication overhead can be reduced, power consumption can be reduced, hardware design can be simplified, and the efficiency of fault diagnosis and repair can be improved. In addition, the domain centralized architecture can also achieve higher software reuse and flexibility, which is convenient for system development and maintenance.
Intewell Vehicle Domain Fusion
In the case of increasingly homogeneous hardware features, the key to vehicle domain integration is software. Intewell uses virtualization technology to virtualize multiple independent systems to run different vehicle services. Through the Intewell Hypervisor virtualization platform, the unit capabilities of various vehicle equipment Centralize, realize the unified management of resources, meet the shared access to hardware by different vehicle subsystems and services, realize software-defined automotive applications, reduce the number of automotive chips used, and promote the intelligent development of the automotive industry.
Intewell satisfies complex scenarios, supports central control domain, body control domain, automatic driving domain, and smart cockpit domain, and breaks the gap between different vehicle business systems. Different systems and different services access the same hardware resources through high-speed buses and virtual IO channels. Build an efficient data intercommunication pipeline between virtual systems, greatly improving communication efficiency, using time-sharing and partitioning features, service isolation technology, and years of experience in aviation and aerospace redundancy control, can greatly improve the resources of on-board computing equipment utilization while ensuring high reliability for automotive applications.
