Configure Virtual Vehicle Components
Use the Data and Calibration pane to configure the virtual vehicle chassis, tires, brakes, powertrain, driver, and environment. The available options depend on the virtual vehicle Powertrain architecture and Model template parameter settings.
Chassis
Use the Chassis parameter to select the body dynamics and mass properties. The available options depend on the virtual vehicle Setup > Vehicle dynamics parameter.
For this example, set Chassis to Vehicle Body 3DOF
Longitudinal
. Use the default parameter values.
Tires and Brakes
Use the Front Tire, Rear Tire, and Brake System options to specify the tire and brake parameters.
Set Front Tire to
MF Tires Longitudinal Front
.On the Front Tire Data tab:
Set tire inertia PlntWhlInertiaFrnt to 1.0 kg·m²
Set tire pressure PlntWhlPrsFrnt to 230000 Pa
Set Rear Tire to
MF Tires Longitudinal Rear
.On the Rear Tire Data tab:
Set tire inertia PlntWhlInertiaRear to 1.0 kg·m²
Set tire pressure PlntWhlPrsRear to 230000 Pa
Set Front Brake Type to
Disc
.Modify the front brake friction material properties:
Set static friction coefficient
PlntBrkStcFricCffFrnt
to 0.40Set kinetic friction coefficient
PlntBrkKinFricCffFrnt
to 0.30
Set Rear Brake Type to
Disc
.Modify the rear brake friction material properties:
Set static friction coefficient
PlntBrkStcFricCffRear
to 0.40Set kinetic friction coefficient
PlntBrkKinFricCffRear
to 0.30
Powertrain
On the Powertrain tab, set parameters for the powertrain systems such as the engine, electric motor, transmission, drivetrain, differential system, and electrical system for your virtual vehicle. The available options depend on the virtual vehicle Powertrain architecture and Model template parameter settings.
For this example, under Powertrain:
Set Drivetrain to
Front Wheel Drive
.Set Drivetrain > Front Differential System to
Open Differential
.Set Electrical System to
1EM
.Use the default values for these DC-DC Converter parameters:
PlntDCDCEff — Overall DC to DC converter efficiency
PlntDCDCLossTbl — Corresponding losses
Click Energy Storage, then select
Mapped Battery (Electric Vehicle 1EM)
. Use the default values for these parameters:PlntBattOpenCirctVolt — Open circuit voltage values, per cell
PlntBattVoltSocBpt — Battery SOC breakpoints for voltage table
Click Electric Machine 1 > Parameters. Use the default values for these motor parameters:
PlntEM1Spd — Motor speed breakpoints for maximum torque
PlntEM1Trq — Maximum torque values
Driver
On the Driver tab, set the driver parameters. The available options depend on the virtual vehicle Powertrain architecture and Model template parameter settings.
For this example, set Driver to Longitudinal Driver
.
Modify these driver settings:
Set driver preview distance DriverPreviewDist to 5 meters
Set driver time constant DriverTimeConst to 0.15 seconds
Environment
On the Environment tab, set the environment parameters. Set Environment to Ambient Conditions
.
Modify these environmental parameters:
Set ambient air absolute pressure EnvAbsPrs to 95000 Pa
Set ambient air absolute temperature EnvAirTemp to 305 kelvins
