In this module, a physical model of vehicle engine management will be created. The model will be first simulated, and then used to create an implementation on the eZDSP-F2812. This board will emulate in real-time the behavior of a vehicle, under various stimuli. In this example, the environment is used to build a physical model of vehicle engine management in simulation, which is then used to create an implementation on the eZDSP-F2812. This board will emulate in real-time the behavior of a vehicle, under various stimuli.


The Texas Instruments C28x family of processors has been designed to implement control applications, for example digital motor control and un-interruptible power supplies. We shall start here with a simple application. In this Laboratory, you will build a simulation model of a vehicle dynamics using Simulink, and then emulate it using the eZDSP-F2812 board.


  • Design a Simulink model of the motion of a vehicle.
  • Run the model using Simulink on a PC.
  • Modify the model for use with the Texas Instruments C28x Digital Signal Processor.
  • Run the modified model on the Texas Instruments F2812 ezDSP.


Beginner; This is intended as the first complete project using Matlab and Simulink.

It is suitable for students who have only limited exposure to Texas Instruments DSPs before.


In developing this Laboratory, the following hardware and software were used:

  • Matlab R2006b with Embedded Target for TI C2000.
  • Code Composer Studio (CCS) 3.1.
  • Spectrum Digital ezDSP F2812 Hardware
  • Some external electronic components costing about $2.


Running the vehicle dynamics simulation

Open VehicleDynamics.mdl .

Engine Management Subsystem

Run the Model.

The input to the model is a ramp generator, which simulates smooth acceleration.

You will see the graphs of Horsepower and Vehicle Speed.

Changing the vehicle mass

Double click on the “Vehicle Dynamics” block. This models the equation of motion using Simulink Blocks.

Vehicle Dynamics

At present, the vehicle mass is 8000 kg.

We will now simulate a small compact car. Change the 1/m gain block to 1/1000 and change the b/m block to 2/1000.

Run the model again and notice the effect on maximum vehicle speed and how long it takes to reach maximum vehicle speed

You might also like to simulate a 35,000 kg lorry. Change the 1/m block to 1/35000 and b/m to 10/35000.

Changing the engine power profile

Double click on the “Engine Management” block. This models the gas in – horsepower out function of the engine.

Engine Management Subsystem

Double-click on the Power Transfer Function

Engine Power Transfer Function

Change the shape of the Power Transfer Function. You may wish to change the gradient or make the plateau wider. Run the model.

Other modifications to the model

Go to the Website of an automobile manufacture, and obtain the actual engine power transfer function for a real car. Run this in the model.

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

Kim Reply
or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
