[. . . ] 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) 10 Version 1. 4 (R2007b) SimDrivelineTM Software New Demos Two new demos have been added. Interface Blocks These demos illustrate how to use the new Interface Elements blocks. See "Interfacing with One-Dimensional Simscape Domains" on page 10. 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 your 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. 13 SimDrivelineTM Release Notes Version 1. 2. 1 (R2006b) SimDriveline Software This table summarizes what's new in Version 1. 2. 1 (R2006b): New Features and Changes No Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports Includes fixes Related Documentation at Web Site No 14 Version 1. 2 (R2006a) SimDrivelineTM Software Version 1. 2 (R2006a) SimDriveline Software This table summarizes what's new in V1. 2 (R2006a): New Features and Changes Yes Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports at Web site Related Documentation at Web Site No New features and changes introduced in this version are · "Improved Clutch Locking and Unlocking" on page 15 · "Changed Transmission Template" on page 15 · "Run-time Parameters Enabled for Key Blocks" on page 16 · "Demos Expanded" on page 16 · "Documentation Enhancements" on page 17 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. 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. 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 15 SimDrivelineTM Release Notes models are not linked to the Transmission Templates library. They continue as valid subsystems in any models where you use them. Run-time Parameters Enabled for Key Blocks Run-time parameters for code generation are now enabled for certain blocks: · Inertia · Simple Gear · Planet-Planet · Ring-Planet · Planetary Gear · Dual-Ratio Planetary · Ravigneaux · Differential Tunable Parameters Certain blocks have some run-time parameters tunable during simulation. The tunable parameters on each block are associated with normal Simulink blocks in the underlying subsystem. · Controllable Friction Clutch · Diesel Engine · Gasoline Engine · Hard Stop · Longitudinal Vehicle Dynamics · Tire · Torsional Spring-Damper Demos Expanded Seven new demos have been added. 16 Version 1. 2 (R2006a) SimDrivelineTM Software Animated Gear Demos These demos include five animated gear demos. · drive_planet_planet_pic · drive_ring_planet_pic · drive_planetary_pic · drive_dual_ratio_planetary_pic · drive_ravigneaux_pic Flexible Shaft Demos The demos also include one flexible shaft demo and one flexible shaft demo library. They illustrate how to model angular flexibility with discrete inertias connected by torsional springs. · drive_flexible_shaft · drive_flexible_shaft_element Documentation Enhancements The online SimDriveline Help has been enhanced with additional multimedia support. · The online Help contains mechanical drawings for five complex gear sets. · The online Help also contains links to five new Web-based AVI animation files that illustrate the motion of these five complex gear sets. You can access these features most easily by using the Examples index in the Help browser, under Gear Drawings and Prerecorded Animations, respectively. 17 SimDrivelineTM Release Notes Version 1. 1. 1 (R14SP3) SimDriveline Software This table summarizes what's new in V1. 1. 1 (R14SP3): New Features and Changes No Version Compatibility Considerations No Fixed Bugs and Known Problems Bug Reports at Web site Related Documentation at Web Site No 18 Version 1. 1 (R14SP2+) SimDrivelineTM Software Version 1. 1 (R14SP2+) SimDriveline Software This table summarizes what's new in V1. 1 (R14SP2+): New Features and Changes Yes Details below Version Compatibility Considerations Yes--Details labeled as Compatibility Considerations, below.

You can linearize a model directly with the linmod command and other MATLAB and Simulink tools. · A new option has been added for enabling and specifying a default velocity tolerance for all clutches in the connected driveline. [. . . ] Once you have downloaded the file fix_opaque. p, place it anywhere on your MATLAB path. At the command line, enter rehash toolboxcache Then run the file on your old model by entering fix_opaque('<model_name>') where model_name is the name of the old model.
