PLANIFICATION DE DEMI-TOUR EN TROIS TEMPS MAITRISÉ PAR COMMANDE POUR VÉHICULES À CONDUITE AUTONOME (ADV)

摘要

In response to a request for a three-point turn, a forward turning path from a current location and heading direction of the ADV is generated. In generating the forward turning path, a forward curvature is determined based on the maximum forward turning angle of the ADV by applying a full steering command. The forward turning path is determined based on the forward curvature from the current location of the ADV. A forward speed profile is calculated for the forward turning path based on perception information that perceives a driving environment surrounding the vehicle at the point in time. In addition, a backward turning path is generated from an end point of the forward turning path based on a maximum backward turning angle associated with the ADV. The three-point turn path is then generated based on the forward turning path and the backward turning path to drive the vehicle to make the three-point turn.
