This example describes a simple model for an Anti-Lock Braking System (ABS). The model sldemo_absbrake.mdl simulates the dynamic behavior of a vehicle under hard braking conditions. The model represents a single wheel, which may be replicated a number of times to create a model for a multi-wheel vehicle.
This model uses the signal logging feature in Simulink. Signals are logged to the MATLAB workspace where they can be analyzed and viewed. You can view the code in sldemo_absbrakeplots.m to see how this is done.
A detailed review of the equations used in this design can be found in the white paper Using Simulink and Stateflow for Automotive Examples. Please note that this paper is based on an older version of Simulink and does not use all the newest block diagramming features in the current version of Simulink.
