Week 7 Challenge

Vehicle parameters are as shown below:

Vehicle parameters are

Mass = 1910Kg

Front area: 2.86Sq.m

Drag Coefficient = 0.417

Rolling resistance coefficient = 0.015

grade angle = 0

Gravitational force 9.8

air density =1.13 mcube

All the vehicle parameters are stored in the workspace and loaded in the command window to make use of the parameters in the simulation.

In the Simulink to analyze the vehicle velocity the equations of the forces acting on the vehicle are simulated.

Each equation is developed in MATLAB Simulink.

The simulation of the above equations is as shown below.

Tractive force is analyzed with the simulation shown below.

To analyze the velocity of the vehicle, the formula used is F=ma

where velocity is the rate of change of acceleration.

The vehicle velocity is compared with the velocity of the drive cycle US06.

The simulation is running for 598 seconds.

Simulation results are as shown below:

The result of the vehicle speed is as shown.
