Week-4 Challenge WOT Condition Part-2

1)What is the difference between mapped and dynamic model of engine, motor and generator? How can you change model type.

Mapped Model:

1. The mapped model is one type where the data points are pre assign in lookup tables.
2. the engine or motor torque required are sensed and motor or engine block generate the required torque output just as required simly without considurung the real time motor or engine parameter.
3. the acuricy of this type is not so high but the simulation is done in much less time.
4. the output values are stored for corrosponding input value of engine or motor.

Dynamic Model:

1. It uses the combination of input from varius subsystem to generates the output.

2. It run the real time simulation were the required input from the drive cycle is taken and for that individual real time simulation gets performed and summing all the results of subsystem gives the output for simulation.

3. The accuracy of the system is verry high as it consist real output from all the subsystem to generate the output.

4. The simulator will take verry long time to compile as it has too many individual simulation running by all the subsystem.

Que 2) How does the model calculate miles per gallon? Which factors are considered to model fuel flow?

1.miles per gallon is fuel economy rating determined by how far a car travells with a gallon of petrol or diesel.

2. In case of electric vehicals it defines with the distance travells by kWA of battery charge.

3. the ammout of fuel energy required to move a engine power car thrue a distance is determined and it compaired to the equivalent amout of electric energy to move a car to a same distance and it express as miles per gallon.

4.the power train block set has a model that calculate miles per gallon for all vehicals.

Que. 3) Run the HEV ReferenceApplication with WOT drive cycle. Change the grade and wind velocity in the environment block. Comment on the results.

in help section ,search for powertrain blockset,do to powertrain blockset and choose explore hybride electrical vehical multimode referance application and run it.

Now we need to chanfe the grade and wind velocity in the invorment block and coment on the results the go to invormrnt block and change the parameter.

grade and wind velocity kept zero
