SimDriveline Block Libraries

About the SimDriveline Block Library

SimDriveline™ software provides a set of block libraries to model driveline systems. This section explains how to open these SimDriveline block libraries and describes the nature of each library.

    Note:   Basic mechanical rotational and translational blocks are contained in the Simscape™ Foundation library.

Access SimDriveline Block Libraries

There are several ways to open the SimDriveline block library.

You can access the blocks through the Simulink® Library Browser. Open the browser by clicking the button. In the contents tree, expand the Simscape entry, then the SimDriveline subentry.

You can also access the blocks directly inside the SimDriveline library in several ways:

  • In the Simulink Library Browser, under Simscape, right-click the SimDriveline subentry. Then select Open SimDriveline Library.

  • At the MATLAB® command line, enter sdl_lib.

SimDriveline Library

The SimDriveline library displays several top-level block groups. You can expand each library by double-clicking its icon.

The next section summarizes the blocks of each library and their use.

Use SimDriveline Block Libraries

The SimDriveline block library is organized into separate libraries, each with a different type of driveline block.

Brakes & Detents

The Brakes & Detents library provides blocks that represent simple clutch-like elements that limit the relative motion of driveline axes with sliding or locking Coulomb friction.


The Clutches library contains blocks that represent various clutches, driveline elements with external input controls, and a variety of geometries that couple driveline axes with Coulomb friction that can lock them together.

Couplings & Drives

The Couplings & Drives library contains blocks that model simple components that couple driveline axes, such as torsional damped springs, torque converters, and variable ratio transmissions. These dynamic elements generate internal driveline torques.


The Engines library contains blocks modeling different types of engines as sources of driveline motion.


The Gears library contains blocks that represent simple and complex gears, driveline elements that couple distinct driveline axes and constrain their relative motions. The Gear blocks range from simple two-wheel gear couplings, to such complex multiwheel and multiaxis gears as planetary and differential gears.


The Sensors library contains blocks that sense dynamic variables, such as power, between two driveline components.

Tires & Vehicles

The Tires & Vehicles library provides blocks that represent components of a full vehicle beyond the drivetrain itself. It includes models of vehicle bodies and tires in contact with the ground.
