Dual Clutch Transmission Model in Simulink
- 35 files
- 1694 downloads
This file contains a dual-clutch transmission model built using Simscape and Simscape Driveline that can be configured for control algorithm development or optimization tests. The clutch states and pre-selection of the gears via dog clutches is controlled by a state machine modeled in Stateflow. Model variants for the transmission and vehicle dynamics can be selected using configurable subsystems. MATLAB scripts demonstrate how to optimize a shift schedule for maximum fuel economy, and how to speed that process using parallel computing. This model can be configured for hardware-in-the-loop testing.
Please read the README.txt file to get started.

Hello Steve - can you send me a version saved in MATLAB R2014b ? My email is- kensilly@2014.cqut.edu.cn. Thank you very much for your time!

Hello Steve - Can you explain clearly all the mathematical models used in the engine model ?

@Catalin - if you provide me your email address, I can send you a version saved in R2015b.

Hello Steve - 1.Open Matlab
2. Run startup_DCT_Model.m
3."DCT Model Demo Scirpt" is opened.
4.Click on "a. Shift Map Parameterization: Shift Map Parameterization GUI" link
As result I get the following errors: "Error using +
Matrix dimensions must agree.
Error in Calc_Shift_Map_RO (line 16)
newpts(:,i) = newpts(:,1)+(i-1)*mingeardiff+rampconst*(i-1)*pedalpos;
Error in ShiftMapParamGUI>ShiftMapParamGUI_OpeningFcn (line 69)
[Upshift_Speeds Downshift_Speeds Pedal_Positions] = Calc_Shift_Map_RO(values{1},values{2});
Error in gui_mainfcn (line 220)
feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});
Error in ShiftMapParamGUI (line 44)
gui_mainfcn(gui_State, varargin{:});"
Should the problem be that I use a 2015b Matlab? I opened the 2017b version on another laptop and save it as 2015b because I don't have a 2017b license.
Thank you very much for your time!
Have a good day -- Catalin

Hi Catalin - I just tested the files (running >>ShiftMapParamGUI) and did not get this error. If you search the files for "FU_SET", you will find it is defined in ./Optim/setup_optim2D_plots.m, and not in the files your diagnostic cites. Please make sure you ran the startup_DCT_Model.m file. If you can tell me the steps you ran that generated this error, I can try them myself. --Steve

Hello. I have a lot of errors on the scripts. Can someone help me please? For example when I try to run "Shift Map Parameterization GUI" from DTC Model Demo Script I get the following erros: Undefined function or variable 'FU_SET'.
Error using +

Error in Calc_Shift_Map_RO (line 16)
newpts(:,i) = newpts(:,1)+(i-1)*mingeardiff+rampconst*(i-1)*pedalpos;

Thank you!

That's the error when i'm trying to run the model simulation in addition to the error when trying to run the gear simulation that i mentioned above.

Hi tupac1971ful - the drive cycle data is loaded into the workspace by the PreLoadFcn of the model Dual_Clutch_Trans.slx. If you run startup_DCT_Model, everything should work fine. The data itself is saved in subfolder Scripts_Data. --Steve

Hello, I'm trying to run the Gear selection animation on Matlab R17a but i get the following error, can you help me?
Invalid setting in 'Dual_Clutch_Trans/Speed Demand/ECE 15 Cycle (Europe)' for parameter 'VariableName'.

Hi Chris -- do you have a license for the MathWorks product Model-Based Calibration Toolbox? That product is required for the data-driven model we have used. If you ">>which xregmaskinitialization -all" and get "xregmaskinitialization not found" then you don't have it. You could probably get a trial license of it from your sales rep.

This is a great model but whenever I change the Block choice of the Engine to 'Data Driven' I get the following error.
"Error in 'Dual_Clutch_Trans/Engine/Data Driven/MBC Engine Model From Dynamometer Data/MBC Brake Torque/xregtwostage/Local Model': Initialization commands cannot be evaluated.
Caused by:
Undefined function or variable 'xregmaskinitialization'."
Its a pity as I am building a diesel engine model and this would have been a great model to learn from.

Sorry, I've realized that we don't have xPCtarget ...

I've tried to run the simulation, but I get the following error:
Making simulation target "Dual_Clutch_Trans_sfun", ...
'Dual_Clutch_Trans_sfun.bat' is not recognized as an internal or external command,
operable program or batch file.
I'm running Matlab 64bits on Windows 7 with all the necessary toolboxes and compilers.
