  • Patent number: 8954217
    Abstract: Aspects of the disclosure relate generally to determining whether an autonomous vehicle should be driven in an autonomous or semiautonomous mode (where steering, acceleration, and braking are controlled by the vehicle's computer). For example, a computer may maneuver a vehicle in an autonomous or a semiautonomous mode. The computer may continuously receive data from one or more sensors. This data may be processed to identify objects and the characteristics of the objects. The detected objects and their respective characteristics may be compared to a traffic pattern model and detailed map information. If the characteristics of the objects deviate from the traffic pattern model or detailed map information by more than some acceptable deviation threshold value, the computer may generate an alert to inform the driver of the need to take control of the vehicle or the computer may maneuver the vehicle in order to avoid any problems.

    Abstract: A proximity sensor includes first and second sensors disposed on a sensor body adjacent to one another. The first sensor is one of an emitter and a receiver. The second sensor is the other one of an emitter and a receiver. A third sensor is disposed adjacent the second sensor opposite the first sensor. The third sensor is an emitter if the first sensor is an emitter or a receiver if the first sensor is a receiver. Each sensor is positioned at an angle with respect to the other two sensors. Each sensor has a respective field of view. A first field of view intersects a second field of view defining a first volume that detects a floor surface within a first threshold distance. The second field of view intersects a third field of view defining a second volume that detects a floor surface within a second threshold distance.

  • Patent number: 8831877
    Abstract: Initial trajectory data that provides an initial description of an approximate trajectory of a device during a time period, and correction data that indicates a location of the device outside the approximate trajectory of the device within the time period, are received. A modified trajectory data that provides a modified description of a corrected trajectory of the device is generated. In particular, terms to express (i) location constraints that limit deformation of the approximate trajectory of the device and (ii) a modification constraint that limits departure of the corrected trajectory of the device from the location indicated by the correction data are generated, and the initial description of the approximate trajectory of the device is modified using the generated terms.

  • Patent number: 8798840
    Abstract: A system and method for mapping parameter data acquired by a robot mapping system is disclosed. Parameter data characterizing the environment is collected while the robot localizes itself within the environment using landmarks. Parameter data is recorded in a plurality of local grids, i.e., sub-maps associated with the robot position and orientation when the data was collected. The robot is configured to generate new grids or reuse existing grids depending on the robot's current pose, the pose associated with other grids, and the uncertainty of these relative pose estimates. The pose estimates associated with the grids are updated over time as the robot refines its estimates of the locations of landmarks from which determines its pose in the environment. Occupancy maps or other global parameter maps may be generated by rendering local grids into a comprehensive map indicating the parameter data in a global reference frame extending the dimensions of the environment.

  • Patent number: 8798841
    Abstract: A system and method designed to improve sensor visibility for a host vehicle operating in an autonomous driving mode when one or more forward-looking sensors are being occluded or obstructed. According to an exemplary embodiment, when a forward-looking object detection sensor is being obstructed by a target vehicle located closely ahead of the host vehicle, the method determines if lateral movement by the host vehicle within its own lane is appropriate to improve sensor visibility around the target vehicle. If lateral movement is deemed appropriate, the method generates lateral movement commands that dictate the direction and distance of the lateral movement by the host vehicle. This may enable the object detection sensors to at least partially see around the obstructing target vehicle and improve the preview distance of the sensors.

  • Publication number: 20140207325
    Abstract: A system and method for providing lane changing maneuvers in an autonomously driven vehicle. The vehicle includes a navigation controller that provides a planned route for the vehicle to follow and a vehicle controller that receives route information from the navigation controller and provides steering, braking and throttle control for the vehicle to follow the route. Either the navigation controller or the vehicle controller may initiate a lane change maneuver to cause the vehicle to be steered from a travel lane to an adjacent lane. In response to the lane change requirement, the navigation controller provides a route segment to the vehicle controller and a lane-change zone so that the vehicle controller can steer the vehicle to the adjacent lane while in the lane-change zone.

  • Patent number: 8781643
    Abstract: A control device and method in which, even when a road deviation operation is performed continuously near a road boundary where sidewalk/road separating blocks are discontinuously lined up, discontinuity does not occur in the control input, and unwanted vehicle behavior does not occur. The sizes of obstacles present around a host vehicle, as well as their relative positions and relative speeds with respect to the host vehicle are detected. An obstacle link length that serves as a determination criterion for virtual linking of obstacles is set. A gap position interpolation process is performed with respect to the linked obstacles. A search is performed as to whether or not there exists a control subject for which collision is to be avoided. A yaw moment for avoiding an obstacle is calculated based on position information of the avoidance control subject.
