  • Publication number: 20210106266
    Abstract: Assessing a likelihood of a person experiencing a fatigue event when the person tasked with monitoring a vehicle operating in an autonomous driving mode may include receiving a set of response times for a psychomotor vigilance test administered to the person. The test may include a plurality of trials which involve a person lifting a finger from a user input device. Whether the person passed or failed each trial of the set of trials may be determined. A model trained using data from prior psychomotor vigilance tests administered to the person may be identified for the person. Results of the determinations of whether the person passed or failed each trial of the set of trials may be input into the model in order to determine a value representative of a likelihood of a fatigue event. An intervention response may be initiated based on the value.

  • Patent number: 10891859
    Abstract: Aspects of the disclosure relate to providing sensor data on a display of a vehicle. For instance, data points generated by a lidar sensor may be received. The data points may be representative of one or more objects in an external environment of the vehicle. A scene including a representation of the vehicle from a perspective of a virtual camera, a first virtual object corresponding to at least one of the one or more objects, and a second virtual object corresponding to at least one object identified from pre-stored map information may be generated. Supplemental points corresponding to a surface of the at least one object identified from the pre-stored map information may be generated. A pulse including at least some of the data points generated by the sensor and the supplemental points may be generated. The scene may be displayed with the pulse on the display.

  • Publication number: 20200326194
    Abstract: Aspects of the disclosure provide for advanced trip planning for an autonomous vehicle service. For instance, an example method may include determining a potential pickup location for a user, determining a set of potential destination locations for a user, and determining a set of potential trips. For each potential trip a vehicle of a fleet of autonomous vehicles of the service may be assigned and trip information, including an estimated time of arrival for the assigned vehicle of the potential trip to reach the destination location of the potential trip, may be determined. The trip information for each potential trip may be provided for display to the user. Thereafter, confirmation information identifying one of the set of potential trips may be received, and the assigned vehicle for one first of the set of potential trips may be dispatched to pick up the user.

  • Publication number: 20200234588
    Abstract: Aspects of the disclosure relate providing a lane change notification when a vehicle is to perform a lane change. One or more computing devices may generate and display a video, where the video is generated from a perspective of a virtual camera at a default position and default pitch. The one or more computing devices may receive an indication that the vehicle is to perform a lane change from a first lane to a second lane and adjust, after the vehicle receives the indication, the default position and default pitch of the virtual camera to an updated position further above the vehicle relative to ground than the default position and an updated pitch directed more towards the ground than the default pitch. The video may be generated and displayed from the perspective of the virtual camera at the updated position and updated pitch.

  • Publication number: 20200192382
    Abstract: Aspects of the disclosure relate to arranging a pick up and drop off locations between a driverless vehicle and a passenger. As an example, a method of doing so may include receiving a request for a vehicle from a client computing device, wherein the request identifies a first location. Pre-stored map information and the first location are used to identify a recommended point according to a set of heuristics. Each heuristic of the set of heuristics has a ranking such that the recommended point corresponds to a location that satisfies at least one of the heuristics having a first rank and such that no other location satisfies any other heuristic of the set of heuristics having a higher rank than the first rank. The pre-stored map information identifying a plurality of pre-determined locations for the vehicle to stop, and the recommended point is one of the plurality of pre-determined locations.

  • Patent number: 10685566
    Abstract: This technology relates to selectively providing details of surrounding roads to passengers of a vehicle. One or more computing devices may calculate a plane relative to an orientation of the vehicle based upon at least one of the vehicle's location, pitch, and yaw. For each surrounding road a distance between the surrounding road and the plane may be determined by the one or more computing devices. The one or more computing devices may generate and display a video indicating a projected trajectory of the vehicle and objects detected by sensors on the vehicle, on a map corresponding to a route the vehicle is currently following and virtual representations of surrounding roads which are within a predefined distance of the location of the vehicle based on the determined distance for each of the surrounding roads.

  • Publication number: 20200080855
    Abstract: The disclosure relates to using ambient lighting conditions with passenger and goods pickups and drop offs with autonomous vehicles. For instance, a map of ambient lighting conditions for stopping locations may be generated by receiving ambient lighting condition data for predetermined stopping locations and arranging this data into a plurality of buckets based on time and one of the stopping locations. A vehicle may then be controlled in an autonomous driving mode in order to stop for a passenger by both observing ambient lighting conditions for different stopping locations and, in some instances, also using the map.

    Abstract: Aspects of the disclosure relate to providing an end of trip sequence when a vehicle is nearing its destination. One or more computing devices may generate and display a video indicating a projected trajectory of the vehicle and objects detected by sensors on the vehicle, on a map corresponding to a route the vehicle is currently following, where the video is generated from a perspective of a virtual camera at a default position and default pitch A determination that the vehicle has reached a threshold relative to the route of the vehicle may be made and the position and pitch of the virtual camera may be adjusted to an updated position above the vehicle and a perspective which looks downwards towards a roof of the vehicle. The video may then be generated and displayed from the perspective of the virtual camera at the updated position.
