Introduction

There is an ever increasing need to meet worldwide governmental automotive safety goals like zero

accidents by automotive manufacturers. As a result, there is a race to create autonomous vehicles among auto manufacturers. To achieve this, more and more automotive electronics safety features need to be implemented in vehicles to meet that goal.

Furthermore, there is an ever growing demand for more creature comfort features to be incorporated into vehicles, culminating to a higher content of body and safety electronics being incorporated into our vehicles in the present and foreseeable future.

Coupled with the need to cut down on product development and manufacturing lifecycle time, automotive electronics suppliers are faced with the need to halve their time to design, integrate and support electronics functional test systems.

This solution brochure describes Keysight Technologies’ PXI-based reference solution for automotive electronics body and safety functional test systems. It provides automotive electronics suppliers with a solution to halve their time to design, integrate and implement their electronics functional test systems.

Body and Safety Electronics Functional Test –Design, Integration and Implementation Challenges

With the need to incorporate more and more electronics content to support autonomously driven vehicles and ever increasing demand for more creature comfort features, automotive electronics suppliers have had to design more complex electronics control units (ECU) with multiple features converged into them.

Automotive electronics applications are unique compared to general industrial electronics tests in that they operate in high voltage and current environments and require support for voltage and current switching, load simulation and measurement in high voltage and current ranges.

Coupled with the need to reduce test system design, integration and deployment time, as well as costs, which are all inversely related, automotive electronics suppliers are in a quandary as to how to solve these challenges.

Key challenges and needs faced by test system architects

–Development of custom switching and load simulation solutions that support high voltage and current ranges while reducing system design, implementation and deployment timelines

–Reducing the cost of test while providing a highly flexible test platform to support automotive body and safety ECUs in a high mix, low volume manufacturing environment

–Reducing the electronics functional test platform footprint to optimize floor space utilization.

To address these test challenges, the automotive body and safety electronics reference solution provides manufacturers with a PXI-based test platform with an integrated modular switch and load solution that is designed from the ground up to support high voltage and current switching and load simulation. Furthermore, it comes with a test sequencer and hardware libraries for the solution, halving the time to design, integrate and deploy functional test solutions.

With its wide range of PXI instruments, pin matrix and load cards that are designed for automotive electronics test, manufacturers are able to use it to establish a standard platform that provides the flexibility to mix and match to a high variance of ECUs while maintaining a standard set of hardware, thus lowering the total cost of test for their manufacturing test needs.
