Vehicle Diagnostics Integrated in System and Software Design
Keep your E/E development process consistent. When you specify diagnostic data and its corresponding software independently – often across different teams and tools – you risk inconsistencies and manual rework. PREEvision eliminates this friction. You integrate diagnostics directly into your development process, bringing software and diagnostic design together seamlessly.
With PREEvision, the details of your diagnostic specification instantly match the implemented application software. This continuous consistency reduces coordination effort, simplifies integration, and prevents expensive late-stage corrections. Get your vehicle diagnostics right the first time.
The Diagnostics Modeling Layer
Design both software and diagnostics in a single, unified tool. PREEvision offers a dedicated modeling layer specifically for diagnostic objects. Within this layer, you define crucial diagnostic information:
- Diagnostic Data Identifiers (DID)
- Diagnostic Controls (I/O Control)
- Diagnostic Routines (Routine)
- Diagnostic Events (Event)
- Diagnostic Trouble Codes (DTC)
You also describe identifiers and diagnostic services for these objects, and model relevant parts of the AUTOSAR event handling directly within the platform.
Two Approaches to Model Diagnostics
PREEvision provides the flexibility you need. Choose between two distinct approaches to model your diagnostics, or combine them for maximum efficiency.
Diagnostic Concept
Describe diagnostics independently of the software. You define all relevant information clearly within the diagnostic layer. This provides a precise specification for later software realization, independent of any immediate technological decisions. Because PREEvision maintains a system-wide view of your E/E networks, you reuse this diagnostic concept across multiple software realizations.
Flexible Workflows for Continuous Consistency
Combine both modeling approaches to establish a continuous, highly efficient workflow – from initial diagnostic requirements straight through to compliant software realization.
Different teams and roles work in parallel, yet PREEvision ensures absolute consistency between requirements, specifications, and the final software realization.
Seamless Diagnostic Data Exchange
Keep your internal and external diagnostic views perfectly synchronized. Export your PREEvision diagnostic model directly to Vector CANdelaStudio. In CANdelaStudio, you refine and supplement the data without ever needing to manually adapt it back to the software.
This seamless data exchange considers services, fault memory, and all details derived from the diagnostic ports. The export scope aligns perfectly with your software-to-hardware mapping, ensuring the right diagnostic objects are available on the dedicated ECU. If you work without a specific software realization, you simply export your software-independent diagnostic concept.
