Focus on SafetyNex
Prudence Base Automated Driving

We have developed SafetyNex a Prudence Metric Measure.
Instead of working on Scenarios (that are quite infinite), we work on separate EVENTS, we calculate a Prudence Function for each event, and we fusion prudence formally to represent any scenario. Prudence functions are a description of autonomy in independant variables.
SafetyNex runs 5% of CPU load on a regular architeture. It reduces heat and energy consumption.
Examples of complex scenarios:

  • Taking over a bicycle approaching a roundabout, with a pedestrian frolicking on the side of the road
  • Truck masking visibility of a pedestrian crossing
  • Prudent behavior on crowdy highways

Complexity is devided by several hundreds.
Tests and validations are drastically simplified.
