Dual Clutch Transmission Model in Simulink
- 35 files
- 2210 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 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 +
Matrix dimensions must agree.
Error in Calc_Shift_Map_RO (line 16)
newpts(:,i) = newpts(:,1)+(i-1)*mingeardiff+rampconst*(i-1)*pedalpos;

[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)

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'.
Caused by:
Error evaluating parameter 'VariableName' in 'Dual_Clutch_Trans/Speed Demand/ECE 15 Cycle (Europe)'

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.
