Vehicle networks, controller validation and electrification test

Automotive Network Data Logging & EV Validation

Primionics configures vehicle-network logging, Automotive Ethernet investigation, real-time HIL and RCP, BMS and inverter test, and synchronized electrical measurement. The solution separates protocol capture, physical-layer analysis, deterministic simulation and power-electronics measurement so each engineering question is addressed with the correct tool.

Capture vehicle networks Record CAN, CAN FD, LIN, FlexRay, Automotive Ethernet and diagnostics with the required channel count and timestamp quality.

Correlate analogue and digital signals Align bus traffic with voltages, currents, sensors, triggers and selected high-speed waveforms.

Execute deterministic scenarios Run plant models, I/O simulation, fault insertion and closed-loop ECU, BMS or inverter tests on real-time targets.

Measure power conversion Characterize battery, charger, DC-link, inverter and motor-drive behaviour with isolated and bandwidth-appropriate instruments.

Manage validation data Store, convert, review and report synchronized engineering data in formats accepted by the analysis workflow.

Synchronized validation architecture

Network traffic, controller behaviour and electrical response must share a common time base.

A valid automotive measurement campaign depends on interface coverage, hardware timestamping, trigger behaviour, sustained recording rate, storage and post-processing. HIL adds deterministic plant models and I/O, while power-electronics validation requires isolated, high-bandwidth electrical measurement.

Protocol decoding on an oscilloscope is useful for signal correlation and fault analysis, but it is not a substitute for long-duration multi-bus logging or formal Automotive Ethernet conformance testing.

100BASE-T1 or 1000BASE-T1 packet capture, physical-layer measurement and conformance testing require different interfaces and fixtures.

PTP or gPTP synchronization must be evaluated across every logger, switch, interface and analysis tool in the chain.

In-vehicle deployment requires review of supply transients, temperature, mounting, storage endurance and data offload.

Validation capability

From vehicle-bus recording to closed-loop controller and EV subsystem test.

Multi-bus vehicle data logging

Capture multiple automotive buses and engineering channels with triggers, pre/post recording and sustained storage sized for the test campaign.

Automotive Ethernet investigation

Analyze 100BASE-T1 and 1000BASE-T1 links using the required tapping, media conversion, timestamping and physical-layer measurement methods.

Real-time HIL and rapid control prototyping

Connect deterministic models, configurable I/O and fault scenarios to the controller under test for repeatable closed-loop validation.

BMS and power-electronics validation

Combine network data with isolated voltage, current, temperature and switching measurements for batteries, chargers, inverters and drives.

Technology stack

Logging, physical-layer analysis, HIL and electrical measurement remain distinct technical layers.

Vehicle-network loggers and interfaces

Dedicated interfaces record CAN/CAN FD, LIN, FlexRay and Automotive Ethernet traffic with hardware timestamps and high-rate storage.

Confirm bus count, transceiver type, timestamp resolution, trigger logic, GNSS/PTP support, file format and environmental rating.

PicoScope automotive and serial analysis

PicoScope supports CAN, CAN FD, LIN, FlexRay, 100BASE-T1 and other protocol decoding for correlating bus content with electrical waveforms.

Use it for waveform and protocol investigation; do not treat protocol decoding alone as a complete fleet logger or conformance system.

Real-time HIL and RCP platforms

Deterministic targets execute plant models and connect through analogue, digital, PWM, resolver, network and fault-insertion I/O.

Define model step size, solver, I/O latency, channel isolation, fault energy, expansion and automation interfaces.

Electrical and power test instruments

Oscilloscopes, differential probes, current probes, sources, loads, power analyzers and DAQ measure EV subsystem behaviour.

Confirm common-mode voltage, bandwidth, insulation, current range, transient response, accuracy and safety category.

Software assurance and traceability

Requirements, static analysis, unit testing, coverage, formal behaviour verification and embedded security support the controller software lifecycle.

Tool output supports engineering evidence; product compliance still depends on the complete process, configuration and certification scope.

Validation programmes

Measurement architectures for benches, vehicles and distributed fleets.

ECU and domain-controller integration

Correlate network traffic, diagnostics, I/O and fault conditions during integration and regression testing.

BMS and battery-system validation

Combine plant models, cell or pack simulation, faults, thermal data and network behaviour for repeatable BMS tests.

Inverter, charger and motor-control development

Use HIL, rapid control prototyping and isolated high-bandwidth measurements for control and power-stage validation.

Road, endurance and fleet logging

Record long-duration multi-bus and sensor data in the vehicle with robust storage, synchronized time and controlled data offload.

Configuration criteria

What determines a reliable vehicle-network and EV validation setup.

Network and channel inventory List bus types, speeds, transceivers, Ethernet PHYs, analogue channels, sensors, video streams and diagnostic interfaces.

Synchronization and recording rate Define timestamp accuracy, PTP/gPTP, trigger correlation, aggregate data rate, burst rate and required record duration.

Bench or vehicle environment Specify supply range, transient protection, temperature, enclosure, mounting, storage access and remote-control requirements.

Data and analysis workflow Define MDF or other formats, DBC or signal databases, conversion, automated analysis, retention and team access.
