Improved Fundamental and Controllable F riction Clutch Mode Logic
The Fundamental Friction Clutch and Controllable Friction Clutch blocks now have additional state transitions to prevent the Clutch from getting stuck in either Wait state. The Clutch can now transition directly from Wait Forward to Wait Reverse and vice versa. This change in clutch logic might lead to changes in simulation results, compared to results produced by earlier versions. If they differ, the new results are more accurate.
Physical Modeling of Mechanical Friction

The existing Controllable Friction Clutch block is unchanged in functional ity. But it is now based on the Fundamental Friction Clutch.
“What’s This?” Context-Sensitive Help Available for Simulink Configuration Parameters Dialog
R2008a introduces “What’s This?” context-sensitive help for parameters that appear in the Simulink Configuration Parameters dialog. This feature provides quick access to a detailed description of the parameters, saving you the time it would take to find the information in the Help browser.

Interfacing with One-Dimensional Simscape Domains
The Rotational Coupling block of the n ew Interface Elements library allows you to connect a SimDriveline driveshaft (driveline connection line) to a Physical Networks line connected to Simscape blocks. T he Rotational Coupling block transfers driveline angular velocity and torque as Physical Networks cross- and through-variables, respectively, without energy loss.
Several new demos illustrate the use of the Interface Elements blocks. See “New Demos” on page 11.

Run-Time Parameters Enabled for Three More Blocks
Run-time parameters for code generation are now enabled for three additional blocks:
• Controllable Friction Clutch (PeakFactor: static friction peak factor)
• Initial Condition
• Torsional Spring-Damper (Backlash: ±backlash: half of full backlash range)
Version 1.4 (R2007b) SimDriveline™ Software

SimDriveline Software Now Requires Simscape Product
SimDriveline software now depends on and requires Simscape software, the foundation for Physical Modeling products. Simscape software includes common Physical Modeling utilities and block libraries. See “Product Overview” and the Simscape documentation.
12
Sharing Models Using Simscape Editing Modes
SimDriveline software now f eatures a selection of two Simscape editing modes that allow full or restricted editing of models.
• The Restricted mode requires SimDriveline product to be installed, but
does not require a license. It allows you to change a limited set of model parameters, but not the blocks or connections, in a SimDriveline model.
• The Full mode requires SimDriveline product to be installed with a license.
It allows you to change anything in a SimDriveline model.
Version 1.3 (R2007a) SimDriveline™ Software
For more details, see “Using the Simscape Editing Mode”.
Block Library Links Must Be Resolved
All SimDriveline blocks in your models must now have resolved block library links. You can neither disable nor break these library links. This is a global Simscape requirement. Consult the Simscape documentation for further details.
Compatibility Considerations
If you have an existing SimDriveline model with disabled or broken links from SimDriveline blocks to the SimDriveline block library, you must restore all the broken block library links for y our model to be valid.
If you have disabled or broken the SimDriveline library link for blocks that you have customized and want to keep these modified blocks in your model, you must move these modified blocks to your own custom library or libraries, then copy the block instances that you need to your model.
You must still restore the block link to its parent library, whether that parent is the SimDriveline block library or your own.

Improved Clutch Locking and Unlocking
The clutch now uses an improved state projection technique when your driveline’s dynamic constraints (clutch modes) change. This method minimizes the kinetic energy of the difference between angular velocity states of the system before and after the change. As a result, clutch mode changes now yield more physical results.
Related Documentation at Web Site
No
See the Controllable Friction Clutch block reference page.
Changed Transmission Template
A new transmission template, CR-CR 4-Speed, has replaced the Simpson 4-Speed transmission block in the Transmission Templates library. The new transmission is constructed and functions somewhat differently from the old one. See the block reference page for more details.
You do not need to update Simpson 4-Speed transmissions in your old models with CR-CR 4-Speed blocks. Instances of transmission templates in your old

Changes to the Driveline Environment Block

• The Simulation mode pull-down menu has been removed.
You can linearize a model directly with the MATLAB and Simulink tools. See “Documentation Improvements” on page 22.
• A new option has been added for enabling and specifying a default velocity
tolerance for all clutches in the connected driveline. See the block reference page and “Changes to the Controllable Friction Clutch Block”.

SimDriveline™ Release Notes
Compatibility Considerations
Driveline Environment blocks are automatically updated when you open a model created from previous SimDriveline versions.
The new block uses the default clutch velocity tolerance configuration. The automatic default is enabled for all non-overriding clutches if you use a variable-step solver.
Changes to the Controllable Friction Clutch Block
The Controllable Friction Clutch block has been changed for this release. A new option, controlled by two new check boxes, has been added to choose between a default velocity tolerance for all clutches and an override velocity tolerance for individual clutches.
See the block reference page and “Changes to the Driveline Environment Block”.

where the leading 1/2 is new.
Version 1.1 (R14SP2+) SimDriveline™ Software
IfyouloadanoldmodelwithDifferential blocks, the SimDriveline software warns you of each obsolete block. If you try to run the model without updating, the simulation stops with an error.
Compatibility Considerations
You need to update any old Differential blocks in your model. SimDriveline version 1.1 provides an update script. To update your model
1 Enter drive_update('drive_model') at the command line.
2 The script updates your blocks, then opens a Save dialog for you to save
the updated model under a new name.
3 The script warns you if you have any Differentials linked to external
libraries.
When you run the script on a model, it does not update any linked libraries. Youmustupdateeachlibraryseparatelythesamewayyouwouldupdate a model.

Caution Once you update a model this way, you cannot recover the old version. If you want to keep it, save the old version under a different name, or save the updated version under a new name.
Efficiency Block Library and Demo
The demos folder toolbox/physmod/drive/drivedemos contains a new block library with driveline efficiency loss blocks and one efficiency demo.
Efficiency Library
The drive_efficiency demo model is a block library. It contains three efficiency blocks (masked subsystems) that model these efficiency-power loss phenomena in d riveline systems:
• Constant efficiency loss (introduces an algebraic loop)
• Variable efficiency loss (introduces an algebraic loop)
21
SimDriveline™ Release Notes
• Power measurement
You can break the induced algebraic loops by inserting Transfer Fcn blocks into the underlying subsystems.
The library also contains two unmasked subsystems that implement the basic load- or torque-based driveline efficiency loss.
Documentation Improvements
The “Advanced Methods” chapter has been improved and expanded.
• The “Improving Perfo rmance ” section has been expanded.
• A new section, “Trimming and Linear izing Driveline Models”, has been
added.

Introduction to SimDriveline Software
SimDriveline Physical Modeling software is a new product in the Physical Modeling family that models and simulates drivetrain systems. With it, you can model bodies rotating around multiple driveline axes, connect them with gears, and create idealized powertrains with clutches, transmissions, and other dynamic elements a nd subsystems. SimDriveline software also lets you actuate and measure rotational motion and torques by interfacing with normal Simulink signal lines and blocks. You can develop controllers with Simulink and connect them to SimDriveline models. With SimDriveline software, you can model, simulate, analyze, and control the rotational motions of complex drivetrains.
