Simulate ECU reaction
With the products from Pickering for (HIL) Hardware-in-the-Loop Simulation we can simulate an ECU's reaction to external fault conditions such as a broken wire or a faulty temperature sensor, giving you the power to thoroughly test the ECU in a virtual environment before proceeding to production level testing. Using our Fault Insertion switch modules, all possible electrical short and open circuits are simulated, erroneous sensor data is applied, and the ECU reaction is captured to see if the design works as defined.
Pickerings HILS products include:
- Modular Breakout Systems
- Fault Insertion Unit Switching
- Programmable Resistors for sensor emulation
Strain Gauge simulation
Sensor and Strain Gauge Simulationfrom Pickering provides the ability to simulate the resistive nature of many environmental sensors in the engine compartment and vehicle cabin is essential for EMU and Body Controller test. When testing ECUs that control airbags, being able to simulate vehicle accelerometers allows the test to verify if the squibs will fire correctly. Pickering has the most extensive range of programmable resistor solutions, in both PXI and PCI formats.
Test of BMS ( Electric Vehicle Battery Management Systems)
At Pickering we have modules for BMS test. With the increasing adoption of electric propulsion systems in road vehicles, one of the significant challenges to be tackled is the effective testing of the Battery Management Systems (BMS). To facilitate BMS testing, our PXI/PXIe multi-cell battery emulator range (model 41/43-752)is ideal for battery stack emulation with the advantage of a modular and scalable platform. These modules enable direct voltage and current readback programmatically or using our soft panel control. Combine these modules with Pickering switch and simulation modules to make a flexible PXI-based BMS test system, including temperature measurement, fault insertion, RTD simulation, and more.
Environmental Testing of DUT’s
Pickerings provide solutions for environmental testing of multiple DUT’s. Our BRIC high-density switching matrices can provide over 6144 cross-points in eight PXI slots, ranging in sizes from 4 to 32 rows and 10 to 1104 columns. The BRIC’s IVI-compliant drivers make it a simple task to integrate into software packages such as our Switch Path Manager signal routing software and National Instruments’ Switch Executive. In addition, our line of solid-state multiplexers and matrices have virtually infinite switch life, making them ideal for extremely long environmental testing. If you prefer an LXI (Ethernet) or USB interface, over 1,000 of our PXI modules (including the BRIC matrices) can be used in our LXI modular chassis. We also offer our high-density LXI matrices (60-55X family and 65-22x family), which have the same functionality as the BRICs and can be operated via an Ethernet connection.
