Abstract: Devices, systems and methods for using system-level malfunction indicators to monitor the operation and resiliency of the autonomous driving system components are described. One example of a method for diagnosing a fault in a component of an autonomous vehicle includes receiving, from an electrical sub-component of the component, an electrical signal, receiving, from an electronic sub-component of the component, a message, and determining, based on the electrical signal and the message, an operational status of the component.

Abstract: Techniques are described to enable a vehicle, such as an autonomous vehicle, to steer and/or apply brakes on a road when a failure condition occurs. An example method for autonomous driving operation includes receiving a reduced set of location information that describes a location of the autonomous vehicle on a road; receiving a reduced set of trajectory information where the autonomous vehicle is expected to be driven; determining a driving path information where the autonomous vehicle is expected to be driven; and in response to determining an occurrence of a fault condition: sending a first instruction to cause the autonomous vehicle to steer the autonomous vehicle using at least the driving path information and the reduced set of location information, and sending a second instruction to cause the autonomous vehicle to apply brakes.

Abstract: Each of a plurality of landing pads is sized and shaped to accommodate an AV. Landing pad sensor(s) are located in or around each landing pad. A control subsystem receives landing pad sensor data from the one or more landing pad sensors and receives, from a first AV traveling to a location of the plurality of landing pads, a request for an assigned landing pad in which the first AV should park. In response to this request, the control subsystem determines, based on the received landing pad sensor data, whether a first landing pad is free of obstructions that would prevent receipt of the first AV. If the first landing pad is free of obstructions, an indication is provided to the AV that the first landing pad is the assigned landing pad.

Abstract: Disclosed are devices, systems and methods for an audio assistant in an autonomous or semi-autonomous vehicle. In one aspect the informational audio assistant receives a first set of data from a vehicle sensor and identifies an object or condition using the data from the vehicle sensor. Audio is generated representative of a perceived danger of an object or condition. A second set of data from the vehicle sensor subsystem is received and the informational audio assistant determines whether an increased danger exists based on a comparison of the first set of data to the second set of data. The informational audio assistant will apply a sound profile to the generated audio based on the increased danger.

Abstract: Techniques for performing a sensor calibration using sequential data is disclosed. An example method includes receiving, from a first camera located on a vehicle, a first image comprising at least a portion of a road comprising lane markers, where the first image is obtained by the camera at a first time; obtaining a calculated value of a position of an inertial measurement (IM) device at the first time; obtaining an optimized first extrinsic matrix of the first camera by adjusting a function of a first actual pixel location of a location of a lane marker in the first image and an expected pixel location of the location of the lane marker; and performing autonomous operation of the vehicle using the optimized first extrinsic matrix of the first camera when the vehicle is operated on another road or at another time.

Abstract: Disclosed are devices, systems and methods related to direct and indirect methods for detecting wind speed and direction during driving. An example method may include estimating, by a processor of a vehicle controller, a speed and a direction of wind movement near the vehicle based on a first sensor output from a wind sensor, or a second sensor output from a non-wind sensor, or a combination of the first sensor output and the second sensor output, wherein a primary purpose of the wind sensor is wind detection, and a primary purpose of the non-wind sensor is different from wind detection, and generating a control output indicative of a vehicle disturbance force resulting from the wind based on the estimated speed and direction of the wind movement.

Abstract: A system includes a camera housing and a control device associated with an autonomous vehicle. The camera housing houses a camera, and is mounted to an autonomous vehicle. The camera housing comprises a glass positioned in front of the camera. The glass is coated with a set of materials comprising a hydrophobic material and an anti-reflective material. The set of materials is configured to reduce ghosting effect on an image captured by the camera. The camera housing further comprises a top portion and a bottom portion. The top portion extends beyond the bottom portion to form a tilt angle. The tilt angle is configured to reduce indirect light from coming into a field of view of the camera. The processor facilitates autonomous driving of the autonomous vehicle using at least the image. The ghosting effect is reduced in the image due to using the set of materials.
