VehicleLab 1.21.0

Vehicle dynamics.
From road to evidence.

Run a Full-Car over a spatial road or real OpenCRG data. Understand the response. Publish the engineering evidence. All in your browser.

Engineering tasks

What do you want to investigate?

Start with an editable example and inspect the evidence supporting each model.

Suspension Kinematics

Inspect Double Wishbone hardpoints, spring/damper compression and signed motion ratios.

Inspect suspension →

Vehicle Ride Simulation

Configure Quarter, Half or Full-Car road inputs. Run, inspect Response and Motion, then export evidence.

Study ride response →

Road Definition & Traversal

Drive a passive Full-Car over procedural roads or supported OpenCRG data at prescribed speed.

Define a road →

01 / Road to evidence

One connected engineering study.

  1. 01

    Road

    Define a surface or import supported OpenCRG road data.

  2. 02

    Traversal

    Set speed, start position and lateral offset.

  3. 03

    Vehicle

    Configure a passive model and run deterministic physics.

  4. 04

    Response

    Inspect plots, metrics and synchronized Motion.

  5. 05

    Evidence

    Publish a report, video and traceable engineering data.

02 / Choose your model

The right level of detail.

Start simple, add pitch, or resolve all four corners. Each model has an explicit engineering boundary.

02DOF

Quarter-Car

Heave, in focus.

Body and wheel motion. A simple reference for suspension response.

Transient & Frequency · Study / Explore / Compare

Model & workflows →
04DOF

Half-Car

Add coupled pitch.

Body heave and pitch with separate front and rear axle inputs.

Transient & Frequency · Study / Explore / Compare

Model & workflows →
07DOF

Full-Car

Four corners. One road.

Heave, pitch and roll. Prescribed corner inputs or spatial road traversal.

Transient Study · Procedural roads / OpenCRG

Model & workflows →

Quarter-Car and Half-Car Explore is transient. Full-Car Compare, Explore and Frequency are not available.

03 / External road data, local computation

Your road is the input.
Evidence is the output.

Import a supported ASAM OpenCRG file locally, review its domain, and define a straight traversal. VehicleLab derives four corner histories from the road surface and retains source and normalized-road fingerprints with the completed study.

Read the OpenCRG guide →
Understand the response

Six Full-Car plots and 16 metrics. Switch to Motion to inspect the model or drive over the road.

Publish completed evidence

Engineering Reports, Wide or Vertical Engineering Video, exact-channel CSV and road excitation data. Exports use the completed study.

Know the boundary

Straight reference lines only. Curved OpenCRG roads are rejected. No steering, yaw, tire slip or contact dynamics. Spatial project saving is not available.

04 / Engineering trust

Inspect the work behind the result.

Transparent equations. Deterministic runs. Local processing. Reproducible provenance.

Verification & Validation →
Visible numerical verification

Model invariants, independent references, Worker parity, road and OpenCRG regression evidence, plus the published Zhao Quarter-Car numerical reproduction.

Explicit physical limits

Generic passive presets have not been correlated to production vehicles. Numerical verification is not physical validation or certification. VehicleLab is not a general multibody or handling simulator.

Start with a question

Define the road. Understand the ride.

No installation. No account. Your computation stays in the browser.
