Most EVs and HEVs on the road today are conversions from IC Engine vehicles to an electrified powertrain and energy system. But has vehicle dynamics been taken care of, and how should we ensure stability of the Converted Electrified vehicle? The presenters address this with a modeling and simulation approach.

Presenter: Pramukh Bharadwaj, PES University

Tools: Modelon Impact

As automotive time-to-market reduces drastically coupled with the inceasing complexity as well as the growing presence of Electrified vehicles, plant modeling has become critical for early stage development. The presenter uses Modelon Impact to do Electric Range test and Maximum Performance/Acceleration Test entirely in the virtual environment.

(Anand was mentor to multiple interns who contributed to this project and couldn't present due to network difficulties.)

Tools: 

Matlab, Simulink, Raptor, VeeCAN800 hardware, KVaser USB-CAN devises and software

Topic: 

An innovative datalogger is developed using Modelbased development approaches, capable of CAN data logging, CAN monitoring of vehicle signals. HMI display and UI control development is covered, as well as handling of USB devices and Database files. Finally the implementation is done on actual hardware.

Gannet calG

Topic

Using the Simulated Engine data and Gannet calG (Accelerated calibration platform), the critical emissions for this Engine – NOx and Soot are optimized at local points and for the Emission cycles. From this approach, multiple solutions are created for achieving Emission cycle NOx and soot results. From these calibration solutions, Input parameter maps for each solution (Main injection timing, Fuel pressure, Boost pressure and Mass air flow) are prepared to flash into ECU and test it on engine.

Topic

Different Numerical methods of Engine modelling are applied to Engine simulation data to select the right model for each response of Engine. These selected models can be used in Engine calibration to achieve good results and very much close to real world results. 

The mathematical modeling methods used are Linear polynomial regression and Gaussian process – Matern kernel and RBF kernel. Using the steady state Part throttle performance data of entire engine operating zone, steady state emission cycle data and Transient cycle data are considered.

By using this methodology, the right models for each responses can be selected for a particular engine and can be used for Engine calibration at different test conditions. Using calG, created multiple calibration solutions for the engine using linear polynomial model.

Topic

Engine testing time and optimization time reduction is the main focus.

• For Engine testing, various Design of experiments designs are studied. Box Behnken design and Plackett Burman design are applied for global and local design of Engine respectively.
• For Engine optimization, Manual calibration is performed using Gannet calG and Engine test data for creating multiple solutions to validate on Engine. Creating each manual solution in calG is very quick and cost effective compared to Manual solution development in Engine test cell.
