Project 2

Model

In this model we have to re-design the Controller part and the Powertrain Part.

1) Controller

In this we have created Mode Selection and re-designed Engine Controller unit and Transmission Control unit.

Engine Control Unit

Idle Speed Controller


Transmission Control Unit

Mode Selection

2) Powertrain


Engine

Electrical Machine

Crank Torque

Transmission

Torque Converter

Battery Pack

We have chosen UDDS Drive Cycle first and HWFET Drive Cycle second.

Results

Case 1 - UDDS Drive Cycle

We have simulated the model for 1369 seconds and we get the following results.

Mode Selection
