At Pickering, we understand you folks in the automotive
industries have the toughest electronic testing requirements. since 1988, we have designed and manufactured commercial
and custom switching and simulation systems, as well as instrumentation for a wide range of diverse functional test and
hardware-in-the-loop simulation applications to help in the test and validation of automotive and aerospace electronics.

Our Switching Solutions for Hardware-in-the-Loop (HIL) Simulation Applications Include:
- Modular Breakout System - Designed in partnership with OPAL-RT Technologies, this Modular Breakout System combines a BoB feature set with the added flexibility of an FIU. By mating the FIU chassis directly to the BoB using our plug-in modules, cabling is minimized, creating a more compact reliable design and improving signal integrity.
- PXI Fault Insertion Unit (FIU) Switching for Fault Insertion Testing - these FIU switch products can be used to introduce electrical faults into a system—this test process typically duplicates various conditions which could occur because of corrosion, short/open circuits and other electrical failure inherited through age, damage or even faulty installation.
- PXI Programmable Resistors for Sensor Simulation - A Hardware-in-the-Loop system employed to test an ECU needs to simulate the behavior of these sensors as accurately as possible to ensure the ECU behaves on the test bench exactly as it would in the real-world. Take a look at our PXI programmable resistor modules developed to help test system designers achieve these goals.
Whose fault is it when ECU's go wrong?
Electronic Control Units (ECUs) are ever-present in today's automotive and aerospace industries. They are increasingly being
used in safety-critical applications that demand the highest reliability in environments where undesirable behavior cannot
be tolerated - the failure of an ECU to act in an appropriate manner under emergency conditions could pose a threat to
life and/or property. Ensuring these demands are unconditionally met requires significant investment in test procedures
An ECU relies on information from a set of sensors and controls to decide what to do with the device it is managing. These sensors are themselves often working in extremely hostile environments (e.g. car or jet engines) and predictably failures can occur in the sensors or their interconnections. The ECU has to respond appropriately to these component failures as well as to genuine system faults. A jet engine needs to shut down if it catches on fi re, but should not shut down if it is clear there is a sensor fault.
Another example of an ECU operating in a hostile environment is the automotive Powertrain Control Modules (PCMs). The PCM is one of the most complex controllers in the modern vehicle and therefore requires rigorous testing of its functionality. The consequences of PCM failure have greater significance in X-by-Wire applications (a collective term for the addition of electronic systems into a vehicle to enhance and replace tasks that were previously accomplished via mechanical and hydraulic systems such as braking or steering), placing increased importance upon these test methods.
In addition to these fault insertion switch and sensor simulation products, we also
offer a comprehensive range of supporting products:
