Patent Applications by Waymo LLC
Inventor(s): Clayton Kunz of Mountain View CA (US) for waymo llc, Timothy Campbell of Mountain View CA (US) for waymo llc
IPC Code(s): G01S7/292, G01S7/295, G01S13/58, G01S13/86, G01S13/931
CPC Code(s): G01S7/292
Abstract: example embodiments relate to radar reflection filtering using a vehicle sensor system. a computing device may detect a first object in radar data from a radar unit coupled to a vehicle and, responsive to determining that information corresponding to the first object is unavailable from other vehicle sensors, use the radar data to determine a position and a velocity for the first object relative to the radar unit. the computing device may also detect a second object aligned with a vector extending between the radar unit and the first object. based on a geometric relationship between the vehicle, the first object, and the second object, the computing device may determine that the first object is a self-reflection of the vehicle caused at least in part by the second object and control the vehicle based on this determination.

IPC Code(s): G01S13/95, B60W40/02, G01S7/288
CPC Code(s): G01S13/951
Abstract: example embodiments relate to techniques for using vehicle image radar to estimate rain rate and other weather conditions. a computing device may receive radar data from a radar unit coupled to a vehicle. the radar data can represent the vehicle's environment. the computing device may use the radar data to determine a radar representation that indicates backscatter power and estimate, using a rain rate model, a rain rate for the environment based on the radar representation. the computing device may then control the vehicle based on the rain rate. in some examples, the computing device may provide the rain rate estimation and an indication of its current location to other vehicles to enable the vehicles to adjust routes based on the rain rate estimation.

IPC Code(s): G05D1/00, B60W30/18
CPC Code(s): G05D1/0212
Abstract: disclosed herein are methods and apparatus for controlling autonomous vehicles utilizing maps that include visibility information. a map is stored at a computing device associated with a vehicle. the vehicle is configured to operate in an autonomous mode that supports a plurality of driving behaviors. the map includes information about a plurality of roads, a plurality of features, and visibility information for at least a first feature in the plurality of features. the computing device queries the map for visibility information for the first feature at a first position. the computing device, in response to querying the map, receives the visibility information for the first feature at the first position. the computing device selects a driving behavior for the vehicle based on the visibility information. the computing device controls the vehicle in accordance with the selected driving behavior.
Inventor(s): Nathaniel Fairfield of Rockingham VA (US) for waymo llc, Joshua Seth Herbach of Mountain View CA (US) for waymo llc, Andrew Hughes Chatham of Mountain View CA (US) for waymo llc, Michael Steven Montemerlo of Mountain View CA (US) for waymo llc
IPC Code(s): G08G1/16, B60W30/00, B60W50/00, G08G1/00, G08G1/01, G08G1/0967
CPC Code(s): G08G1/161
Abstract: example systems and methods allow for reporting and sharing of information reports relating to driving conditions within a fleet of autonomous vehicles. one example method includes receiving information reports relating to driving conditions from a plurality of autonomous vehicles within a fleet of autonomous vehicles. the method may also include receiving sensor data from a plurality of autonomous vehicles within the fleet of autonomous vehicles. the method may further include validating some of the information reports based at least in part on the sensor data. the method may additionally include combining validated information reports into a driving information map. the method may also include periodically filtering the driving information map to remove outdated information reports. the method may further include providing portions of the driving information map to autonomous vehicles within the fleet of autonomous vehicles.
