[ECU Testing] ECU debugging in the advanced electrification era using flexible triggering and multi-ch high-speed logging

A fault model reproduced with HILS more comprehensive

Using hardware-in-the-loop simulation (HILS) for ECU testing at R&D helps dramatically increase product development speed, versus previous test methods performed with actual vehicles. However, developers may not be able to reap the full benefits from using HILS without a comprehensive test phenomena model. To ensure the accuracy of development and verification while using HILS, the development models must comprehensively cover defects caused by multiple factors.

Causes and results: Not one to one, but multiple to multiple

The conventional method was to capture CAN message errors and sensor signals through multiple channels to detect the causes of analog errors in sensors and actuators. However, a single factor may result in multiple outcomes, or multiple causes may result in a single outcome. It would be very helpful for developers to be able to observe between multiple devices when various conditions occur, such as communication signal disturbance, unexpected noise on the power supply line, and PWM oscillation.

Can your capture those conditions with your current low-speed logger?

Increased communication speed among in-vehicle devices has resulted in significant rise times of error signals. There is an increasing risk of overlooking defect signals while using signals originally developed to operate in a low-speed logging environment of several hundred kbps. We now need a faster logging environment without detection failure.

Easily link in triggers and data recording

Now you can link the powerful trigger function of an oscilloscope and the multi-channel high-speed capture capabilities of a digitizer. This feature is unique to PXIe.

PXIe enables the InfiniiVision 3000T X series oscilloscope to be used on the benchtop. Each module provides two channels. By using multiple modules, you can easily build a multi-channel oscilloscope environment.

Various trigger functions

M924xA PXIe oscilloscope allows triggering with protocols such as CAN communication and time waveforms. It also supports Keysight’s original zone touch trigger and will not miss any error. Industry-standard PXIe platform This solution is built with industry-standard modular instruments that are easily adaptable and modifiable. You will be able to maximize your ROIC over the years. M3100A multi-channel high-speed PXIe digitizer Eight channels for each module. High-speed sampling at 500 kSa/s (standard) or 10 MSa/s (optional) achieves gapless data recording. It also allows logging for several hours. Use your usual oscilloscope GUI for easy post-analysis Analysing long hours of data captured is time consuming. The Infiniium Offline Software enables subsequent data analysis using trigger and protocol analysis functions similar to those offered by the oscilloscope.
