Applicazioni automotive
Simulink consente di modellare e simulare una serie di sistemi automobilistici. È possibile modellare e simulare il veicolo e l’ambiente, nonché sviluppare algoritmi di controllo per le applicazioni automotive. Questi modelli di esempio illustrano le applicazioni automotive.
Inoltre, i seguenti prodotti ampliano l'ambiente di Simulink per le applicazioni automotive:
Powertrain Blockset fornisce modelli applicativi di riferimento completamente assemblati di propulsori automobilistici, compresi i sistemi a benzina, diesel, ibridi ed elettrici.

Model Fault-Tolerant Fuel Control System
Combine Stateflow® and Simulink® capabilities to model hybrid systems. This type of modeling is particularly useful for systems that have numerous possible operational modes based on discrete events. Traditional signal flow is handled in Simulink while changes in control configuration are implemented in Stateflow. The model described in this example represents a fuel control system for a gasoline engine. The system is robust in that it detects individual sensor failures, and the control system is dynamically reconfigured for uninterrupted operation.

Model Engine Timing Using Triggered Subsystems
Model a four-cylinder spark ignition internal combustion engine from the throttle to the crankshaft output using triggered subsystems. In this example, the sldemo_engine model is based on [1].
Engine Timing Model with Closed Loop Control
Develop and implement a closed loop control algorithm for the open loop engine model described in Model Engine Timing Using Triggered Subsystems. In this example, the model sldemo_enginewc contains a controller that regulates engine speed using a fast throttle actuator such that changes in load torque have minimal effect. The controller is implemented using a discrete PI controller.
Building a Clutch Lock-Up Model
Use Simulink® to model and simulate a rotating clutch system. Although modeling a clutch system is difficult because of topological changes in the system dynamics during lockup, this example shows how enabled subsystem can easily handle such problems. We illustrate how to employ important Simulink modeling concepts in the creation of the clutch simulation. Designers can apply these concepts to many models with strong discontinuities and constraints that may change dynamically.
Modeling Clutch Lock-Up Using If Blocks
Use If/Else subsystems to build a clutch model. An 'If' subsystem models the clutch dynamics in the locked position while an 'Else' subsystem models the unlocked position. One or the other is enabled using the 'If' block. The dot-dashed lines from the 'If' block denote control signals, which are used to enable If/Else (or other conditional) subsystems. Checking any of the boxes on the GUI produces a plot of any of the selected variables (versus time).

È possibile utilizzare questo modello insieme a una simulazione del gruppo propulsore per studiare lo slittamento longitudinale derivante dalle variazioni dell'impostazione dell'acceleratore.
