Robotic vehicle active safety systems and methods

摘要

Systems and methods implemented in algorithms, software, firmware, logic, or circuitry may be configured to process data and sensory input to determine whether an object external to an autonomous vehicle (e.g., another vehicle, a pedestrian, road debris, a bicyclist, etc.) may be a potential collision threat to the autonomous vehicle. The autonomous vehicle may be configured to implement active safety measures to avoid the potential collision and/or mitigate the impact of an actual collision to passengers in the autonomous vehicle and/or to the autonomous vehicle itself. Interior safety systems, exterior safety systems, a drive system or some combination of those systems may be activated to implement active safety measures in the autonomous vehicle.

主权项

1. A method comprising:
receiving trajectory data representing a trajectory of a driverless, autonomous vehicle in an environment external to the autonomous vehicle; sensing an object in the environment; determining object data comprising a position of the object, an object type of the object, and an object classification of the object; determining one or more predicted locations of the object in the environment based on the object data; determining a predicted collision location based on the trajectory data and the one or more predicted locations of the object in the environment; determining a first threshold location in the environment between the object and the predicted collision location; determining a second threshold location in the environment between the object and the predicted collision location, the second threshold location being closer to the collision location than the first threshold location; sensing an updated position of the object in the environment; implementing a first safety action using a safety system in response to the updated position corresponding to the first threshold location; and implementing a second safety action using the safety system in response to the updated position corresponding to the second threshold location.
