Abstract: Systems and techniques for determining deceleration controls to use in a trajectory for use in stopping a vehicle are described. A deceleration determination system may receive a trajectory from a trajectory determination system and determine, based on various deceleration parameters, the appropriate controls to configure in a longitudinal profile of the trajectory and the suitable implementation points for implementing the controls. The deceleration determination system may determine deceleration data for various types of trajectories that a vehicle computing system may select from for operating the vehicle based on current conditions.

Abstract: Techniques are described for determining to modify a coordinate system in response to the occurrence of a condition. As non-limiting examples, such conditions comprise distance traveled, speed of the vehicle (or system), an amount of computational resources available, a time since the last change, a number of objects present, the presence (or absence) of a particular object proximate the vehicle, a distance to a proximate object, based on a particular frequency, or the like. Such modifications may improve the operation and safety of a computing system used for path planning and trajectory generation by allowing lower precision numerical representations to be used in safety-critical situations while avoiding potential computational errors that would otherwise result from using such a representation.

Abstract: Techniques for validating or determining trajectories for a vehicle are discussed herein. A trajectory management component can receive status and/or error data from other safety system components and select or otherwise determine safe and valid vehicle trajectories. A perception component of a safety system can validate a trajectory upon which the trajectory management component can wait for selecting a vehicle trajectory, validate trajectories stored in a queue, and/or utilize kinematics for validation of trajectories. A filter component of the safety system can filter out objects based on trajectories stored in a queue. A collision detection component of the safety system can determine the collision states based on trajectories stored in a queue or determine a collision state upon which the trajectory management component can wait for selecting or otherwise determining a vehicle trajectory.

Abstract: Systems and techniques for determining a trajectory for use in controlling a vehicle are described. A trajectory determination system may generate a variety of trajectories for potential use in controlling a vehicle, including a maximum braking trajectory that enables the maximum application of the vehicle's brakes. A vehicle computing system may determine a distance between vehicle and an obstacle and stopping distances for the various trajectories and implement the maximum braking trajectory after determining that the distance to stop for that trajectory is the same as, but not substantially greater than, the distance between the vehicle and the obstacle.
