Domain Controller

As vehicles become increasingly electrified, autonomous, and software-defined, domain controllers are taking center stage, serving as a centralized electronic control unit to power advanced automotive technologies. Domain controllers manage vast amounts of data from sensors, infotainment features, and Advanced Driver Assistance Systems (ADAS) components – delivering the intelligence required for modern mobility. Positioned at the core of a vehicle’s electronic architecture, these systems consolidate multiple functions into more powerful computing units. But with this consolidation comes added complexity.

Next-generation vehicles have not only robust infotainment and comfort features, but also have complex ADAS technologies – including LiDAR, radar, and cameras that require reliable central control units to ingest data, make rapid decisions, and communicate with sensors both inside and outside the vehicle. Domain controllers must function flawlessly, regardless of thermal, signal, or mechanical challenges. If not addressed, these challenges can lead to system malfunctions, degraded performance, shortened component lifespan, and even safety risks.

Qnity helps design engineers meet the unique demands of domain controller applications with a portfolio of advanced materials. 

• Board-level shields and SMD metal contacts minimize crosstalk and malfunctions caused by disruptive electromagnetic interference (EMI). 
• Thermal interface materials provide efficient heat dissipation, improving the long-term reliability of domain controller systems. 
• Electroplating solutions protect high-voltage environments from hazards such as overheating or electrical shorts. 

Additionally, Qnity’s solutions are engineered for durability, maintaining mechanical integrity in high-vibration environments, allowing domain controllers to operate reliably throughout a vehicle’s lifestyle.

Looking ahead, domain controllers will only grow more complex—handling greater computing power, tighter packaging, and increasing safety demands. Qnity continues to innovate with advanced materials that meet the needs of design engineers as they address these challenges within domain controllers.
