These features are working in the PERRINN 424 project, available on GitHub.

Kinematic suspension model
  • Simulation of the suspension geometry for true wheel motions.
  • Configuration of instant centers, instant axis, roll center.
  • Unsprung mass.
  • Steering axis and caster via configurable kingpin.
  • Hard collisions (wheel rim) and soft collisions (tire).
  • Separate suspension and tire stiffness properties.
Advanced tire contact patch
  • Compute the contact patch out of several contact points.
  • Vertical tire stiffness.
  • Longitudinal (radial) and lateral tire stiffness properties.
  • Carcass simulation (relevant when riding kerbs).
  • Tire deformation.
  • Elastic adherence when stopped.
Tire Friction Model 2.0 (SDK V10 alpha)
  • Advanced industry-grade tire friction model: slip ratio, slip angle, load function.
  • Detailed editors with graphic charts for analysis.
  • Scriptable Tire Friction architecture: custom tire friction models may be implemented and used seamlessly.
  • New realtime telemetry plots: Slip Ratio, Slip Angle, Wheel Torque.
  • Reorganized telemetry data widget with slip and ground material properties always visible.
  • New traction and steering aids designed for this model.
Scriptable Wheel Collision model
  • New VPP WheelCollider component completely replacing Unity's.
  • Custom wheel collision models may be implemented and plugged into VPP vehicles.
  • Vehicles may use different wheel collision models simultaneously.
New Input Devices Manager
  • Learn and configure any device in minutes
  • Support any number of simultaneous devices
  • Load and save device setup to file / JSON
  • As simple to use as current Unity Input
  • Support for hot plugging devices
Electric MGU (Motor Generator Units)
  • Parametric torque maps
  • Efficiency factor
  • Regenerative braking
  • Front-rear axle balancing
  • Detailed editors with graphics charts
  • Combination with mechanical brakes
Advanced telemetry system
  • Multiple channels with different update frequencies and ranges
  • Easily extensible from vehicle components (VehicleBehaviour)
  • Different chart types: time/distance based, scatter plots, histogram
Engine-independent code (in process)
  • Custom API exposing all elements and features required by VPP.
  • Interoperability with the equivalent elements in the host engine (i.e. Vector3, Transform...)
  • Math, physics, graphics, application, etc.
  • All engine-dependent code resides in a single location. Easily portable to other engines.
