Tesla ha rilasciato un importante aggiornamento software del suo sistema di guida autonoma "Full Self-Driving". L'update, basato su oltre 250.000 filmati raccolti dalla sua flotta con software FSD Beta (che conta oltre 100.000 unità), contiene novità di primo livello.

Tra queste, una maggiore precisione nel rilevamento di ostacoli ed oggetti grazie ad una ricostruzione più accurata della geometria circostante. Inoltre, sono stati assicurati diversi passi in avanti dell'intelligenza artificiale, che ora riconoscerebbe gli ostacoli lungo il percorso. Tesla, tra l'altro, ha anche affermato di aver rimosso le tre reti neurali più vecchie dal sistema.

Attraverso questo aggiornamento, dunque, Tesla prova ad alzare l'asticella della qualità complessiva del suo sistema di guida autonoma, fermo ancora al "livello due" visto che viene considerato come un sistema di assistenza alla guida.

  • Upgraded decision making framework for unprotected left turns with better modeling of objects' response to ego's actions by adding more features that shape the go/no-go decision. This increases robustness to noisy measurements while being more sticky to decisions within a safety margin. The framework also leverages median safe regions when necessary to maneuver across large turns and accelerating harder through maneuvers when required to safely exit the intersection.
  • Improved creeping for visibility using more accurate lane geometry and higher resolution occlusion detection.
  • Reduced instances of attempting uncomfortable turns through better integration with object future predictions during lane selection.
  • Upgraded planner to rely less on lanes to enable maneuvering smoothly out of restricted space.
  • Increased safety of turns crossing traffic by improving the architecture of the lanes neural network which greatly boosted recall and geometric accuracy of crossing lanes.
  • Improved the recall and geometric accuracy of all lane productions by adding 180,000 video clips to the training set.
  • Reduced traffic control related false slowdowns through better integration with lane structure and improved behavior with respect to yellow lights.
  • Improved the geometric accuracy of road edge and line predictions by adding a mixing/coupling layer with the generalized static obstacle network.
  • Improved geometric accuracy and understanding of visibility by retraining the generalized static obstacle network with improved data from the auto labeler and by adding 30,000 more video clips.
  • Improved recall of motorcycles, reduced velocity error of close-by pedestrian and bicyclists, and reduced heading error of pedestrians by adding new sim and auto-labeled data to the training set.
  • Improved precision of the "is parked" attribute on vehicles by adding 41,000 clips to the training set. Solved 48% of failure cases captured by our telemetry of 10.11.
  • Improved detection recall of faraway crossing objects by regenerating the dataset with improved versions of the neural networks used in the auto labeler, which increased data quality.
  • Improved offsetting behavior when maneuvering around cars with open doors.
  • Improved angular velocity and lane-centric velocity for non-VRU objects by upgrading it into network predicted tasks.
  • Improved comfort when lane changing behind vehicles with harsh deceleration by tighter integration between lead vehicles future motion estimate and planned lane change profile.
  • Increased reliance on network-predicted acceleration for all moving objects, previously only longitudinally relevant objects.
  • Updated nearby vehicle assets with visualization indicating when a vehicle has a door open.
  • Improved system frame rate +1.8 frames per second by removing three legacy neural networks.
