WO Graduation Assignment: Comparison and implementation of on-board diagnostic methods in Eindhoven

Functiebeschrijving

As a control function engineer you will work on a graduation assignment to improve our diagnostic method portfolio. A heavy-duty engine requires On-Board diagnostics to monitor for emissions related failure modes. With a short lead time in engine development projects, it is challenging to design a diagnostic that can detect and pinpoint failures, while being robust in all possible conditions. One can think of part-to-part variation, the different driveline configurations, application, mileage, ambient/environmental conditions and so on. Physical models can be developed early and result in a long verification time, but these models are sensitive for unmodelled dynamics/phenomena. Data driven methods, for example statistical classification models or neural networks, can sometimes better cover systems that are difficult to model, but these models require a large amount of good data that is only available at a later stage when the system is mature.

The goal of this assignment is an in-depth investigation on: - Diagnostic methods - what is current state-of-the art and being used in the industry and are they suitable for our product - Consideration and comparison of the relevant methods, for example: - Effort and activities needed to get a robust diagnostic - Where this effort is concentrated with respect to the project phase - Robustness to system/ performance changes - Flexibility to update/ tweak diagnostics at a late stage - Possibility to reduce sensitivity on current sensors - How the lead time can be improved. In general, we want to maximize verification time and minimization iterations. For example: - By using simulation/synthetic/ enhanced data - Methods to reduce the risk of overfitting, etc. The thesis (could) consist of: - Literature study on diagnostic methods - Define which methods are best suited for our product, for example: Physical modeling, Kalman filtering, machine learning methods etc. - Considerations when choosing a specific method - Work out and compare implementation on one or multiple system diagnostics creating a clear overview of various diagnostic methods - Possibly verify diagnostic functionality with a Rapid-Control-Prototyping (RCP) implementation on an engine/aftertreatment/vehicle and demonstrate the diagnostic - Report and present results As a student you will report to our student mentor within the team.

Jouw profiel

• Master degree student in a relevant area, preferably Automotive / dynamics and controls
• Extensive knowledge of MATLAB and Simulink
• Good statistical knowledge
• Experience with heavy duty diesel engine or after treatment development is a pre

Afdeling

Within PACCAR Inc., DAF Trucks Global Engine Development is the center of competence for engine and aftertreatment development. In our state-of-art engine development center we develop engine families for future regulations, for DAF, Peterbilt and Kenworth trucks. Our engines and trucks are best-in-class products in the transportation world, being always driven by providing environmentally friendly products with highest reliability and best cost-effectiveness for our customers. The Engine Integration & Validation department is responsible for definition, integration, verification, and validation of engine and after treatment families towards performance requirements. The department is split into 8 groups and the System Function Design group holds a vacancy for a graduation project.
