thereby controlling external devices or circuits.
In order to solve these problems of distributed EEA, people have gradually integrated many ECU functions that are similar or separated into a processor hardware platform with stronger performance than ECU, which is the automotive “Domain Control Unit (DCU)”. The emergence of domain controllers is an important milestone in the evolution of automotive EE architecture from ECU distributed EE architecture to domain centralized EE architecture (as shown in Figure 2-2).
The domain controller is the core of every functional domain in the automotive industry, mainly composed of three parts: the domain main control processor, the operating system, and application software and algorithms. Platformization, high integration, high performance, and good compatibility are the main core design ideas of domain controllers. By relying on high-performance domain controller processors, abundant hardware interface resources, and powerful software features, domain controllers can integrate core functions that originally required many ECUs, greatly improving system functionality integration. In addition, standardized interfaces for data exchange can greatly reduce the development and manufacturing costs of this part.
For the specific division of functional domains, each automotive host manufacturer will divide them into several different domains based on their own design concepts. For example, BOSCH is divided into five domains: Power Train, Chassis, Body/Comfort, Cockpit/Entertainment, and ADAS.
This is also the most classic five domain centralized EEA, as shown in Figure 2-2. Some manufacturers further integrate the five domain centralized architecture, merging the original power domain, chassis domain, and body domain into the vehicle control domain, thus forming a three domain centralized EEA, namely: Vehicle Control Domain Controller (VDC), ADASAD Domain Controller (ADC), and Cockpit Domain Controller (CDC). Both Volkswagen’s MEB platform and Huawei’s CC architecture belong to this three domain centralized EEA.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 12P0631X012 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
