Electronic Control Unit Functional Test

An NI engineer works on the ECU Test System

  • Test ECUs in Production

    Most of the innovations in today’s vehicles are powered by electronic control units (ECUs). This added complexity can lead to failures, and functional test offers one last chance to reduce risk and ensure uncompromising quality. As new innovations drive up the number of tasks test engineers must perform throughout the tester life cycle, the time and resources to complete the tasks are shrinking. The only solution to this challenge is to move faster.

ECU Test System Architecture

High-performance Instrumentation

Side view of PXI input and output modules

PXI technology provides high-throughput data transfer and tight synchronization with integrated timing and triggering. Configure dozens of PXI instruments and I/O modules such as digital multimeters, source measure units, power supplies, oscilloscopes, function generators, isolated analog input/analog output modules, and digital input/output modules.

Production-compatible Core Rack

Racks are more than enclosures. NI rack solutions feature 24U and 40U form factors, gray paint that complies with electrostatic discharge (ESD) control standards (IEC 61340-5-1), and safety, mechanical, and power components ideal for your production needs.

Powerful Application Software

NI software options for ECU test include TestStand for test plan implementation and parallel testing, InstrumentStudio™ for higher abstraction to configure and debug test steps, and Switch Executive to manage signal routing.

Switch, Load, and Signal Conditioning

Faster Deployment

Use a functional test system with the I/O you need and a consistent software toolchain for test plan development, debugging, deployment, and upkeep. Also achieve parallel test capability out of the box for a wide range of ECUs.

Leaner Operation

Deploy and operate end-of-line testers efficiently and reliably while using NI global service programs, training, and maintenance tools to reduce your risk of production downtime.

Scalability for Any Test Needs

Take advantage of a standardized starting point for hardware, reuse test modules and sequences, and add third-party or customized components to meet your specific ECU test needs now and in the future.

Sustainable Execution

Achieve results faster and more confidently with the ECU Test System’s maintenance and diagnostic tools, bring-up services, training, and development software that improve the experience for both test engineers and operators.

    Hyundai Kefico Moves 6X Faster Through Standardization

    Hyundai Kefico stopped redesigning testers from scratch with every new ECU test by adopting a customizable, user-defined test system using an NI automated test solution.

    CUSTOMER STORIES
 

NI’s ECUTS is the only system we could find in the market that met our aggressive schedule for deploying production testers for our ECUs. Everything from the initial configuration, delivery at our site, and the bring up service, was significantly faster, so we had more time to focus on our test plan implementation and make our project successful.
