Modeling an Automatic Transmission Controller

Open Example

*This example shows how to model an automotivedrivetrainwith Simulink®.

**Stateflow® enhances the Simulink model withitsrepresentation of the transmission control logic and control modules and units applications. 

***Simulink providesapowerfulenvironment for the modeling and simulation of dynamicsystems(cars- trains and planes) and processes.

*In manysystems, though, supervisoryfunctionslikechanging modes or invoking new gain schedules must respond to eventsthatmayoccur and conditions thatdevelop over time.

**In manysystemswecanaddlosses, parasitics, criticalpathes and critical topologies of control in each system depending on nomber of parameters and testingexperiences.

***As a result, the environmentrequires a language capable of managingthese multiple modes and developing conditions.

*In the followingexample, Stateflow shows itsstrength in thiscapacity by performing the function of gearselection in an automatic transmission.

**This functioniscombinedwith the drivetraindynamics in a natural and intuitive manner by incorporating a Stateflow block in the Simulink block diagram.

In the system of the cars or the planes or the 

trains.

Consisting of four cylindres and coefficient of 

eachcylender.

 In getthese contraints of input/output.

And showing output signals in the figures 

after.

          Fig 3 and 4 for the 4 cylenders cars

Hope this helping engineers to simulate also 

4 cylender cars and 6 cylender cars.

Don't miss to put the good coefficients and parameters for each cylender

thank you my freinds in engineering hope you build in good things.

merci on souhaite vous construirez en bonne chose bénéficier à vos pays.
