The method includes dividing the path into one or more partial paths and carrying out a predetermined number of repetitions of the following steps: calculating a time-optimal trajectory for each of the partial paths, joining the time-optimal trajectories for all partial paths, checking whether predetermined limit values are not exceeded and whether the fastest movement has been found, and varying one or more of the movement parameters.

Abstract: Systems and techniques for determining deceleration controls to use in a trajectory for use in stopping a vehicle are described. A vehicle control system may determine if a stopping point is represented in a spatially-generated trajectory (e.g., controls to be commanded at particular locations) and, if so, whether the points in the trajectory approaching the stopping point meet near-stop conditions. If so, the system operated the vehicle in stop vehicle control mode, generating temporally-based controls to slow the vehicle more comfortably. Otherwise, the system operates the vehicle as normal, using spatially-based controls for controlling the vehicle.

Abstract: This document describes trajectory planning in a three-dimensional (3D) search space with a space-time artificial potential field. An example system includes a processor that obtains an initial pose, a goal pose, and an obstacle map for an environment. The processor uses a parking trajectory algorithm to determine a trajectory by searching in a space-time artificial potential field. The trajectory includes a series of 3D waypoints, including two-dimensional (2D) positional coordinates and time coordinates, to navigate from the initial pose towards the goal pose. Operation of the host vehicle is then controlled to maneuver along the trajectory using an assisted-driving or autonomous-driving system. In this way, path searching is performed in the entire 3D search space rather than iterating between two 2D search planes. This allows motion planning for autonomous parking, especially with static and dynamic objects present, to determine an optimal trajectory in a single iteration.
