    摘要： Systems, methods, and computer program products for guiding vehicles. A vehicle control system detects obstacles and avoids contact between the vehicle, and the obstacles by solving a path planning problem using a four-phase system. In a parking scenario, switching control laws are used to drive the vehicle to a target line, and a forward path segment and a reverse path segment defined. The two path segments are connected along the target line to define a path for entering or exiting the parking space. Objects in a driving environment may be avoided by identifying an obstacle corner, defining an avoidance circle (62), (185) around the obstacle corner, and determining a path that allows the vehicle to avoid penetrating the avoidance circle. A line-of-sight guidance method may be used to follow the path by defining target points on the path at a lookout distance l, and steering the vehicle using the target points.

    摘要： An autonomous mobile device (AMD) may move around a physical space performing various tasks. Most of the sensors on the AMD may be directed towards the front and sides of the AMD to facilitate autonomous navigation, interactions with users, and so forth. The AMD may return to a dock to recharge batteries, replenish consumables, transfer payload, and so forth. The AMD uses the sensors to approach the vicinity of the dock. Once in the vicinity, the AMD turns around and backs into the dock. This orientation allows the AMD to continue to operate the forward-facing sensors and interact with users while docked. The AMD uses inductive sensors to detect metallic targets located at particular positions in the dock. Output from the inductive sensors provides information about the relative position of the AMD with respect to the dock and is used to steer the AMD into a desired docked position.
