Drivers

Create and tune driver profiles that simulations use for throttle, braking, steering, and gear shift behavior.

Drivers are reusable SIM inputs that describe a driver or baseline driver profile. Simulations select a driver with the vehicle and ambient. FastSim also selects a circuit. OpenSim also selects a driver input.

Use drivers when you need to compare driver assumptions, keep team naming consistent, or tune driver limits before running simulations.

Before you start

Select the correct team.
Create, edit, duplicate, and delete actions depend on module permissions.
Choose a naming convention that your team can recognize in simulation setup and analysis.

Create a driver

Open Drivers from the sidebar.
Select New.
Enter Name.
Enter Short Name. Short name is limited to 7 characters.
Add Notes when the driver profile needs context.
Add Tags when the team filters drivers by program, event, or baseline.
Save the driver.

The driver appears in the Drivers table and in simulation driver selectors for the active team.

Edit driver metadata

Open Drivers.
Select the row action for the driver.
Choose Edit.
Update name, short name, notes, or tags.
Save the changes.

Tune driver parameters

Open Drivers.
Select the driver row.
Review Driver Parameters on the detail page.
Edit the parameter values that should represent the driver or baseline profile.
Save with Update Data when the action appears.

Driver fields

Field	What it means	Notes
Name	Full driver or profile name.	Required.
Short Name	Compact label used in tables and selectors.	Required. Max 7 characters.
Notes	Team context for the driver profile.	Optional.
Tags	Labels used for filtering and organization.	Optional.

Driver parameters

Parameter	Description	Units	Default	Validation / Range
Max Throttle Rate	Maximum rate the driver can change throttle position.	%/s	500	100 to 10000
Max Brake Rate	Maximum rate the driver can change brake position.	%/s	500	100 to 10000
Max Brake Force	Maximum brake pedal force the driver can apply.	N	800	10 to 10000
Max Steering Wheel Angle Rate	Maximum rate the driver can change steering wheel angle.	°/s	1000	100 to 10000
Min Gear Shift Interval	Minimum time between two gear shifts.	s	0.2	0 to 2

Use a driver in simulations

FastSim requires Vehicle, Circuit, Ambient, and Driver.
OpenSim requires Vehicle, Ambient, Driver, and Driver Input.
Use tags and clear short names so race engineers can select the intended driver profile during setup.

Troubleshooting

Problem	What to check
New is hidden	Confirm your role has module create permission.
Cannot save metadata	Check required name and short name. Short name must be 7 characters or fewer.
Cannot save parameter changes	Fix validation errors in Driver Parameters before selecting Update Data.
Driver is missing from simulation setup	Confirm the correct team is active and the driver exists in that team.
