What is a domain controller? Overview of the Domain Controller Market
What is a domain controller
A significant result of the development of automotive intelligence and informatization in the past decade is the increasing use of ECU chips.
From traditional engine control systems, airbags, anti lock braking systems, electric power steering, and vehicle electronic stability systems;
Moving on to smart meters, entertainment and audio systems, and assisted driving systems; There are also electric drive control, battery
management system and on-board charging system on electric vehicles, as well as the booming on-board gateway, T-BOX and auto drive system.
The traditional automotive electronic and electrical architecture is distributed (as shown in Figure 2-1), and the various ECUs in the car are
connected together through CAN and LIN buses. The total number of ECUs in modern cars has rapidly
increased to dozens or even hundreds, and the complexity of the entire system is increasing, approaching the upper limit. In today”s trend of
software defined cars and the intelligent and networked development of cars, this ECU based distributed EEA is increasingly exposing many problems and challenges.
