Modified Vehicle Dynamics Block

a. Tabulate the fuel economy numbers (kmpl) for UDDS cycle.

For UDDS cycle:

1. For UDDS cycle:

b. Plot the time trace for engine, transmission input, transmission output and wheel speed on one plot.

c. Plot engine torque, engine power, fuel rate and fuel consumption using subplots.

Engine Power:

Fuel rate (g/s)

Fuel Consumption (g)

d. Plot accelerator and brake pedal, gear command, vehicle desired and actual speed, vehicle distance using subplots.

e. Plot the engine operating points on the engine fuel map.

2. For HWFET cycle:

a. Tabulate the fuel economy numbers (kmpl) for UDDS and HWFET cycle.

For HWFET cycle:

b. Plot the time trace for engine, transmission input, transmission output and wheel speed on one plot.
