Safety Force Field
SW Release Applicability: This module is available in NVIDIA DRIVE Software releases.

About This Module

The Safety Force Field module takes surrounding perception of

  • static and moving obstacles around the ego-vehicle, and
  • the Egomotion or VehicleIO state of the ego car, and
  • road structure (optional).

The ego-vehicle and the obstacles are actors. The module then predicts whether a collision is likely to happen between an actor and the ego-vehicle, after all actors have executed their safety procedures.

A Safety Force Field is computed for each predicted collision between an actor and the ego-vehicle. These Safety Force Fields generate control constraints for actuation. If the current ego-vehicle control violates a control constraint, it is corrected to a safe control.
