Aim to find the task of project 2
To find the figures first we have to use the initial mscript from attached files to get the variables for simulink model to run and to get the figure of the model

Simulink model
Driver model
the driver model is used to control for the pedals of both accelerator and brakes and the input of velocity and time is given
Controller Block
The controller block which is used control the engine, transmission, brake control unit
A state flow machine is used to represent the supervisory control unit, which decides the operationg mode.
while it is start/stop mode or cruising mode or regen braking mode. for each modes the Engine drive and the
motor drive are controlled.
Shift logic block
Powertrain model
the powertrain model of the vehicle is consist of the controls of engine, transmission,differential,wheels anf vehicle dynamics of the vehicle which used to run the vehicle
Transmission Block
Torque Converter
EM motor subsystem
Crank Subsystem
Differential Model :
Engine block
the engine of a vehicle is one of the main components to run the vehicle the engines are run on fossil fuels in IC engines and EV's are run with batteries the two types of IC's are(Diesel, and Petrol)
vehicle dynamics Block
after moduling the both engine and vehicle dynamics model we can run the model respected model then we have to select the postprocessing script file to plot the output figures of the model
after run the model we can get the variables for the post processing script
the screenshot of the scope are attached
