Breaking Down Ecotron’s Zonal Control Unit

SV82399A Zonal Control Unit – Simplifying Vehicle Control for Next-Gen EVs

As electric and intelligent vehicles grow more complex, automakers face a challenge: managing hundreds of sensors, actuators, and control systems efficiently and reliably. Zonal Control Units (ZCUs) address this, and Ecotron’s SV82399A ZCU leads the way.

What is a Zonal Control Unit?

Unlike traditional domain-based architectures, where controllers manage groups of functions, ZCUs manage systems within specific vehicle zones. Acting as local gateways, they connect the central processor with sensors, actuators, and other ECUs. By decentralizing control, ZCUs:

• Reduce wiring complexity and vehicle weight
• Optimize placement and use of electronic components
• Enable faster communication via high-speed networks like Ethernet
• Simplify power distribution

In short, ZCUs make modern vehicles more efficient, reliable, and scalable.

The SV82399A: Master Controller for Vehicle Zonal Architecture 

The SV82399A ZCU is designed to act as the master controller in zonal vehicle architectures. It receives driver inputs such as pedal position, gear selection, and vehicle speed, and coordinates key systems, including the motor, battery pack, and accessory systems, meet driving torque requirements. Beyond performance control, it performs fault diagnosis, vehicle monitoring, and mode switching, ensuring both safety and reliability.

Built for Connectivity

The SV82399A is designed to integrate effortlessly across zones, offering a wide range of interfaces to accommodate the growing number of vehicle systems. Its flexibility makes it a powerful gateway for communication and control.

Powered by a Proven Chipset

At the heart of the SV82399A is the Infineon ASIL-D rated TC399 chip, a processor built for both performance and safety. With its 300 MHz frequency and 16 MB of flash memory, the TC399 delivers the computational power needed to handle complex vehicle functions with precision. Its floating-point support enables advanced calculations, which is particularly critical in safety-critical applications. Together, these features ensure that the SV82399A can support the growing demands of intelligent vehicle systems with confidence.

Rugged by Design

The SV82399A is housed in a die-cast aluminum casing, it combines strength with effective heat dissipation. The unit is rated IP67, making it both waterproof and dustproof, while a breathable valve helps maintain internal balance in fluctuating environments. It has been rigorously tested against vibration, shock, corrosion, and electromagnetic compatibility to ensure long-term reliability. Operating across temperatures from -40°C to +105°C and weighing less than 2.7 kg, the SV82399A offers a compact, durable solution for zonal vehicle control.

Why the SV82399A Matters

The SV82399A combines reliable hardware, broad connectivity, and the proven performance of the Infineon ASIL-D rated TC399 chip. By supporting zonal architectures, it helps reduce vehicle complexity, improve efficiency, and provide a solid platform for the future of electric and intelligent vehicles.
