Applications and system integration

Applications with the PSI5-Simulyzer

Product background and integration into existing test setups.

HiL test setup with PSI5, SPI and SQUIB

Connected test setup

HiL simulation for airbag ECUs

A complete HiL simulation for an airbag ECU combines internal acceleration sensor signals via SPI with peripheral acceleration and pressure sensor signals via PSI5. The SQUIB Box measures and analyzes ignition timing. A PC system processes the data and connects to the simulators via USB or a network.

Six or more PSI5-Simulyzers are often used alongside several SPI-Simulyzers. A higher-level configuration assigns devices and signal traces and defines the bus parameters. This simplifies API operation and enables continuous monitoring of the sensor signals.

Technical background

PSI5 explained

PSI5 is a cost-effective sensor interface frequently used in automotive applications. An ECU communicates with one or more peripheral sensors. Sensor data is transmitted by current modulation over the supply lines.

Frames contain two start bits, 8 to 24 payload bits and one parity bit or, optionally, three CRC bits. An ECU voltage synchronization signal initiates a data transmission period.

EMC testing

Optical PSI5 transmission into the test chamber

The optoPSI5 system from mk-messtechnik transmits PSI5 signals over optical fibers. It can be used to bring a PSI5 interface into an EMC test chamber.
