Virtual Vehicle Composer

Configure, build, and analyze a virtual automotive vehicle

Description

The Virtual Vehicle Composer app enables you to configure and build a virtual vehicle that you can use for system-level performance analysis, including component sizing, fuel economy, drive cycle tracking, software integration testing, and hardware-in-the-loop (HIL) testing. Use the app to quickly enter your vehicle parameter data, build a virtual vehicle model, run test scenarios, and analyze the results.

The virtual vehicle model contains the blocks and reference application subsystems available with Powertrain Blockset™ and Vehicle Dynamics Blockset™. You can use the app to quickly configure the architecture and enter parameter data.

If you have Powertrain Blockset, use the app to:

Design tradeoff analysis and component sizing.
Configure hybrid-electric vehicle (HEV) architectures.

If you have Vehicle Dynamics Blockset, use the app to:

Analyze ride-and-handling effects of standard test maneuvers.
Visualize your virtual vehicle in Unreal Engine^® simulation environment.

To build, operate, and analyze your virtual vehicle, use Composer tab in the Virtual Vehicle Composer to follow these workflow steps:

Step	Section		Description

Required Products

The Virtual Vehicle Composer requires either of these products:

Powertrain Blockset
Vehicle Dynamics Blockset
If you want to run your virtual vehicle in the Unreal Engine 3D simulation environment, see the requirements in Unreal Engine Simulation Environment Requirements and Limitations.

Vehicle Data

Use the app to quickly enter your virtual vehicle parameter data for the vehicle architecture, vehicle dynamics model, chassis, powertrain, and driver. For each selection, enter the parameter data.

Parameter	Description
Vehicle Architecture	Use the parameters to specify the vehicle type. By default, the parameter is set to `Conventional Vehicle`. The conventional vehicle architecture has a spark-ignition (SI) internal combustion engine, transmission, chassis, and associated powertrain control algorithms. If you have Powertrain Blockset, you can specify these model architectures for hybrid electric vehicles (HEVs). The HEV and EV model architectures include an internal combustion engine, chassis, transmission, battery, motor, generator, and associated powertrain control algorithms.
Vehicle Model	Use the parameter setting `Longitudinal Vehicle Dynamics` to configure a model suitable for fuel economy and energy management analysis. If you have Vehicle Dynamics Blockset, you can specify `Lateral Vehicle Dynamics` to configure a model suitable for vehicle handling, stability, and ride comfort analysis. The virtual vehicle uses the Z-up coordinate system as defined in SAE J670 and ISO 8855. For more information, see Coordinate Systems in Vehicle Dynamics Blockset.
Chassis	Use the Chassis parameters to select the tire, brake type, steering system, and suspension systems for your virtual vehicle. If you have Powertrain Blockset, you can set Tire to `Longitudinal Tire`, which implements a tire model suitable for longitudinal vehicle dynamics studies, including fuel economy and energy management analysis. If you have Vehicle Dynamics Blockset, you can set Tire to `Longitudinal Combined Slip Tire`, which implements a tire model suitable for lateral vehicle dynamics studies, including vehicle handling, stability, and ride comfort analysis. The model implements longitudinal and lateral behavior of a wheel characterized by the Magic Formula. You can use fitted tire data sets provided by the Global Center for Automotive Performance Simulation (GCAPS). If you have Vehicle Dynamics Blockset and set Vehicle Model to `Lateral Vehicle Dynamics`, you can specify Steering System and Suspension parameters.
Powertrain	Select the engine, transmission, drivetrain, differential system, vehicle control unit, and electrical system parameters for your virtual vehicle. The available parameters depend on the product license, vehicle architecture, and vehicle model.
Driver	The parameter setting `Longitudinal Driver` implements a longitudinal speed-tracking controller. If you have Vehicle Dynamics Blockset you can set Driver to `Predictive Driver` to track longitudinal velocity and a lateral reference displacement.
Environment	The parameter setting `Standard Ambient` implements an ambient environment model.

Vehicle Scenario and Test

Select the scenario to use to test your virtual vehicle.

If you set Scenario to Drive Cycle, you can use:

Drive cycles from predefined sources. By default, the block includes the FTP–75 drive cycle. To install additional drive cycles from a support package, see Support Package For Maneuver and Drive Cycle Data. The support package has drive cycles that include the gear shift schedules, for example JC08 and CUEDC.
Workspace variables that define your own drive cycles.
.mat, .xls, .xlsx, or .txt files.
Wide open throttle (WOT) parameters, including initial and nominal reference speed, deceleration start time, and final reference speed.

If you have Vehicle Dynamics Blockset and set Vehicle Model to Lateral Vehicle Dynamics, you can select maneuvers for vehicle handling, stability, and ride analysis. Maneuvers include:

Double Lane Change
Increasing Steer
Constant Radius

If you want to run your virtual vehicle in the Unreal Engine 3D simulation environment, set Simulation 3D to Enable. For hardware requirements, see Unreal Engine Simulation Environment Requirements and Limitations.

Data Logging Editor

Select the model signal data to log when operating your virtual vehicle. Options include vehicle position, velocity, and acceleration. By default, the app lists frequently-used signals.

Virtual Vehicle

Build your virtual vehicle. When you build, the Virtual Vehicle Composer creates a Simulink model that contains the specified vehicle architecture and data.

Run Test Plan

Simulate your model in the scenario that you specified in Vehicle Scenario and Test.

Simulation Data Inspector

Use the Simulation Data Inspector to view and inspect the simulation signals.

If you run your virtual vehicle through more than one test scenario, the Simulation Data Inspector displays the results from the last simulation. To see results from previous simulations, load the archived results.
