What is Qualifier?
Qualifier is a configurable web application for working with vehicle data. It shows how a fleet is performing, helps teams spot patterns, and provides a path from a broad fleet view down to the recording behind a specific issue.
This tutorial introduces the application, the larger Aptiv Connect Qualifier system, and the in-vehicle hardware that supplies its data. The next tutorial follows that data from collection to the files you see on screen.
What people use it for
Manufacturers, suppliers, and fleet teams use Qualifier for work such as:
- Collect vehicle data in detail, with microsecond precision
- Build reports and visualizations that speed up root-cause analysis
- Get alerts about diagnostic trouble codes (DTCs) and custom-defined events
- Target emerging issues with data campaigns
- Monitor vehicle location and health live
- Bring in data from other data loggers for an enterprise-wide view
- Capture and analyze video from in and around test vehicles
- Integrate road and weather data
- Assign issues to people, and comment on them
- Download data, including the full controller area network (CAN) bus log
Data, information, and knowledge
Qualifier does more than store the output of a data logger. One way to understand the difference is to follow the progression from raw data to useful knowledge.
Data is raw fact: the ones and zeroes on the CAN bus. They tell you what happened without telling you what it meant. Most data logging tools stop here.
Information is data with relationships between the points. Qualifier can take data about engine starts and turn it into information about how often a start missed its threshold, and what else was happening in the vehicle at the time.
Knowledge is information with structure, which is to say patterns you can see. The reporting and visualization tools exist to get you here, because this is the level at which you can act.
Aptiv Connect Qualifier
The web application is one part of a larger system.
| Part | What it does |
|---|---|
| Qualifier | The web application. View data, run analytics and reports, investigate root causes, set up alerts |
| Developer | The application Aptiv customer support engineers use to configure your in-vehicle hardware and Connect Edge software remotely |
| Connect Edge | Edge computing software running on the in-vehicle hardware. It analyzes locally and uploads what is worth uploading |
| Hardware | The in-vehicle recorders. The EP-2000 is the current flagship |
| Professional services | Aptiv customer support engineers and data scientists |
In short, the system collects data in the vehicle, processes it at the edge to limit unnecessary transmission, sends the useful results to the cloud, and makes them available for analysis in Qualifier.
Optional additions
| Add-on | What it gives you |
|---|---|
| Qualifier Ingest | Brings data from other brands of data logger into Qualifier |
| Command Center | Live fleet monitoring, with alerts on preconfigured events |
| Qualifier Video System | Four-camera capture in and around the vehicle |
| Environmental Insights | Road and weather data alongside your own |
| Qualifier Analytics | Custom interactive reports beyond the standard set |
| AC-Dash | An in-vehicle tablet giving drivers feedback and capturing audio |
| Movimento | Reflash services for keeping module software current, with traceability |
The hardware
EP-2000
The EP-2000 is Aptiv's most capable recorder. It supports more than twice as many CAN channels as the EP-1000, plus LIN, DoIP, CAN FD, and Automotive Ethernet. It connects up to four cameras and has the processing headroom for the data loads of modern vehicle architecture.
EP-1000
The EP-1000 is designed for demanding pre-production validation. It provides everything available on the EP-600, plus simultaneous collection across CCP/XCP, J1939, and more. It stores full-fidelity CAN history, keeps a 1 Hz log through a trip, takes snapshots on configurable triggers, and captures high-speed data around an anomaly.
EP-600
The EP-600 is an entry-level, two-channel CAN recorder for a narrower signal set. It detects anomalies and watches configurable thresholds, analyzes in the vehicle, and sends only what matters to the cloud.
