A Quick Overview

Environmental Pollution has become a rising concern over the past few years. Governments all over the world have rolled out incentives for people opting for hybrid and electric vehicles instead of conventional IC engine vehicles.

As of today, electric vehicles are limited by the range they can cover. Hybrid Electric Vehicles hold the advantage over electric vehicles because they employ IC engines as well. Since there are two sources of power generation in a Hybrid Electric Vehicle, the design is quite complex. This course has been designed to impart knowledge on how hybrid electric drives work in the automotive industry. This, along with knowledge on how to model powertrains will prove to be beneficial when trying to seek an opportunity in the HEV/EV domain.

This course covers details on:

  • Basics of Hybrid Electric Powertrains 
  • Existing and Future Architectures
  • Current Trends in the industry
  • Powertrain System Design and Modelling
  • Simulation and Controls related to Powertrains

The projects included in the course

1. Development of a forward energy-based fuel consumption model of a conventional vehicle

Highlights

The task of this project is to compute the fuel economy numbers for the given vehicle (kmpl) on the urban cycle (UDDS) and highway cycle (HWFET). Also, to analyze and understand the vehicle operating points in terms of engine speed, torque, transmission speeds, pedal positions, gear, distance traveled, etc.
To do that, the following steps need to be followed:

  1. Load the Project1 folder as the Current Folder in Matlab.
  2. Run the “Project1_InitFile.m” Matlab script.
  3. The provided vehicle Simulink model “Project1_VehicleModel.slx” is incomplete. The engine and vehicle dynamics block contents have been deleted. Build the Simulink blocks by referring to the course lecture and example block images provided. You can run the model and analyze the results using a ‘Scope’ for debugging.
  4. Add additional ‘To Workspace’ blocks for transferring the desired Simulink vehicle data into the Matlab workspace.
  5. Modify the “Project1_ProcessingFile.m” as per the desired plots and required calculations.
  6. Write a project report that contains the following:
    1. Tabulate the fuel economy numbers (kmpl) for UDDS and HWFET cycle. This forms the baseline numbers for comparing with the future hybrid version.
    2. Plot the time trace for engine, transmission input, transmission output and wheel speed on one plot.
    3. Plot engine torque, engine power, fuel rate and fuel consumption using subplots.
    4. Plot accelerator and brake pedal, gear command, vehicle desired and actual speed, vehicle distance using subplots.
    5. Plot the engine operating points on the engine fuel map.
    6. Write down appropriate brief comments on each of these plots, describing the vehicle behavior throughout the drive cycle.
    7. Generate the plots for both drive cycles.

2. Development of a forward energy-based fuel consumption model of a P1 hybrid vehicle.

Highlights

The task of this project is to quantify the improvement in fuel economy numbers for the hybrid vehicle (kmpl), compared to the conventional vehicle, on the urban cycle (UDDS) and highway cycle (HWFET). Also, to analyze and understand the vehicle operating points in terms of engine and motor speed, torque, transmission speeds, pedal positions, gear, distance traveled, battery voltage, current, SoC etc.
To do that, the following steps need to be followed:

  1. Load the Project2 folder as the Current Folder in Matlab.
  2. Run the “Project2_InitFile.m” Matlab script.
  3. Copy the Conventional vehicle Simulink model created for Project 1 in this folder.
  4. Modify this model into a hybrid vehicle model. The lecture presentations can be used as reference. Battery and Supervisory controller models developed in the assignments can be reused.
  5. Add additional ‘To Workspace’ blocks for transferring the desired Simulink vehicle data into the Matlab workspace.
  6. Simulate the hybrid model on the desired drive cycles.
  7. Write a project report that contains the following:
    1. Tabulate the fuel economy numbers (kmpl) for UDDS and HWFET cycle. Compare these numbers with the baseline numbers for conventional vehicle model from Project 1.
    2. Plot the time trace for engine, transmission input, transmission output and wheel speed on one plot.
    3. Plot engine torque, engine power, fuel rate and fuel consumption using subplots.
    4. Plot accelerator and brake pedal, gear command, vehicle desired and actual speed, vehicle distance using subplots.
    5. Plot the engine operating points on the engine fuel map.
    6. Plot motor speed, torque, motor input power using subplots.
    7. Plot pack voltage, current and SoC using subplots.
    8. Plot the motor operating points on the motor input power map, with the motor max motoring and generating torque curves.
    9. Write down appropriate brief comments on each of these plots, describing the vehicle behavior throughout the drive cycle.
    10. Generate the plots for both drive cycles.
