In digital automobile production, all vehicles are permanently online and communicate with the production infrastructure via a backend. The DSA circulating test system Smart Diagnostics Grid enables vehicles to be permanently connected with the infrastructure during the entire configuration and diagnostics process. The Smart Diagnostics Grid thus ensures more transparency and efficiency in automobile production.
The integration of the vehicle into the existing plant IT is made possible by means of DSA circulating adapters (either in the Lean Diagnostics Edge or Smart Diagnostics Edge concept), which remain plugged into the vehicle over several production cycles and establish a continuous WLAN communication with the test computer. While in the Lean Diagnostics Edge approach (e.g. with the DSA WDI-2X) the vehicle is connected to the component for sequence execution via Wi-Fi and the sequence execution is running on a related hardware computer at the production line or on a computer center on a virtualized tester, the Smart Diagnostics Edge is a circulating tester with integrated test sequence execution (e.g. DSA smartMDI).
In vehicles that are already equipped with the DSA Connected Vehicle Onboard Diagnostic software stack (with the core components PRODIS.PDU and PRODIS.MCD), the Onboard Diagnostics Edge integrated into the vehicle allows integration of the vehicle directly into the test system. The execution of the test procedure can take place both in the vehicle itself and externally.
The concept of the Smart Diagnostics Grid enables the more flexible distribution of diagnostic scopes and their continuous monitoring throughout the entire production process of the vehicle in the assembly plants.
The circulating test system is controlled by the control logic in PRODIS.PlantHUB, which is the central element of the circulating test system.
Nowadays, there is a multitude of different possibilities for flashing, configuring, calibrating, setting up and diagnosing vehicles or their control units in vehicle production lines. Depending on the particular use case and the performance of the vehicle’s on-board computer, the various aspects of a test client can be distributed to different components:
All-in-One Diagnostics Tester: The DSA Multi-Function Tester MFT-3 includes the aspects user interface (HMI), process execution and diagnostic kernel (sequence engine, MCD-3D kernel/PRODIS.MCD) as well as vehicle interface (PRODIS.PDU/D-PDU API, diagnostic protocols) in one device.
Lean Diagnostics Edge: The vehicle’s connection is made by means of a remote VCI plugged into the vehicle, e.g. DSA WDI-2X, which is connected to the component for sequence execution via WLAN. Here, the execution of the test takes place either on a corresponding hardware computer at the line or in the computer center on a virtualized tester. User interaction can be done, for example, via our Remote Communication Unit RCU or smart glasses.
Smart Diagnostics Edge: Compared to the Lean Diagnostics Edge, this variant is based on a circulating tester with integrated sequence execution, such as the DSA smartMDI. Here, the user interaction can also be done via smart glasses or tablets.
On-Board Diagnostics Edge: For the connected vehicle, the vehicle’s on-board computer contains the VCI. Depending on the performance, the execution of diagnostic scopes on the on-board computer is also possible. The user interface (HMI) can be, in addition to conventional display devices such as line monitors, tablets or the DSA handheld terminal RCU, an AR / a VR glasses.
PRODIS.PlantHUB: PRODIS.PlantHUB monitors production environments that use one or more of the approaches described above by managing the various components and controlling their interaction. The key feature of PRODIS.PlantHUB is the allocation of appropriate resources for each specific diagnostic task and vehicle as well as the automatic triggering of all diagnostic tasks at the right time.
PRODIS.PlantHUB is our central control and visualization tool of the PRODIS system for circulating test systems in automotive production.
The WDI-2X is a further development of the WDI-2 for utilizations in automotive production and is mainly used as a circulating adapter.
The smartMDI combines the benefits of an all-in-one test device with the flexibility of distributed test components and is suitable for a circulating test system.
