Abstract: Techniques are disclosed for evaluating an autonomous vehicle (“AV”) control system by determining deviations between data generated using the AV control system and manual driving data. In many implementations, manual driving data captures action(s) of a vehicle controlled by a manual driver. Additionally or alternatively, multiple AV control systems can be evaluated by comparing deviations for each AV control system, where the deviations are determined using the same set of manual driving data.

Abstract: A structure of a silicon photonics device for LIDAR includes a first insulating structure and a second insulating structure disposed above one or more etched silicon structures overlying a substrate member. A metal layer is disposed above the first insulating structure without a prior deposition of a diffusion barrier and adhesion layer. A thin insulating structure is disposed above the second insulating structure. A first configuration of the metal layer, the first insulating structure and the one or more etched silicon structures forms a free-space coupler. A second configuration of the thin insulating structure above the second insulating structure forms an edge coupler.

Abstract: A light detection and ranging (LIDAR) system for a vehicle includes a transmitter, a receiver, one or more scanning optics, and a circulator. The transmitter is configured to output a transmit beam. The receiver includes a first receive grating coupler and a second receive grating coupler. The circulator is configured to receive the transmit beam and provide the transmit beam to the one or more scanning optics, receive a return beam from reflection of the transmit beam by an object, split the return beam into at least a first component and a second component, and direct the first component to the first receive grating coupler and the second component to the second receive grating coupler.

Abstract: Systems and methods related to controlling an autonomous vehicle (“AV”) are described herein. Implementations can obtain a plurality of instances that each include input and output. The input can include actor(s) from a given time instance of a past episode of locomotion of a vehicle, and stream(s) in an environment of the vehicle during the past episode. The actor(s) may be associated with an object in the environment of the vehicle at the given time instance, and the stream(s) may each represent candidate navigation paths in the environment of the vehicle. The output may include ground truth label(s) (or reference label(s)). Implementations can train a machine learning (“ML”) model based on the plurality of instances, and subsequently use the ML model in controlling the AV. In training the ML model, the actor(s) and stream(s) can be processed in parallel.

Abstract: A LIDAR transceiver includes a source input, coherent cells, and an optical switch. The optical switch is configured to switchably couple the source input to the coherent cells. At least one of the coherent cells includes an input port, an optical antenna, and a splitter. The input port is coupled to the optical switch and the splitter is coupled between the input port and the optical antenna. The splitter is configured to split a received portion of a laser signal into a local oscillator signal and a transmit signal, where the transmit signal is emitted through the optical antenna. A reflection of the transmit signal is received through the optical antenna as a reflected signal, where the splitter is further configured to output a return signal that is a portion of the reflected signal.

Abstract: An integrated chip packaging for a LIDAR sensor mounted to a vehicle includes a laser assembly configured to output a beam, an optical amplifier array chip configured to amplify a beam, and a transceiver chip coupled to the laser assembly and the optical amplifier array chip. The transceiver chip may be configured to emit the beam with reference to a first surface of the transceiver chip through an optical window and receive a reflected beam from a target through the optical window. The integrated chip packaging for the LIDAR sensor defines the configuration of optical components for providing a path for the optical signal to travel in and out of the LIDAR sensor and dissipating the heat generated by the optical components for improved performance.

Abstract: A method may include obtaining lidar data comprising a plurality of lidar returns from an environment of an autonomous vehicle. The lidar data may be processed with a machine learning model to generate, for the plurality of lidar returns, a plurality of first outputs that each identify a respective lidar return as belonging to an object or non-object and a plurality of second outputs that identify lidar returns belonging to objects as harmful or non-harmful to the autonomous vehicle. A subset of the lidar returns identified as belonging to objects that (i) do not correspond to any of a plurality of pre-classified objects and (ii) were identified as harmful to the autonomous vehicle may be determined. The autonomous vehicle may be controlled based at least in part on the subset of lidar returns.

Abstract: Sensor data collected from an autonomous vehicle can be labeled using sensor data collected from an additional vehicle. Labeled sensor data can generate targeted testing instances for a trained machine learning model, where the trained machine learning model is used in generating control signals for an autonomous vehicle. In many implementations, targeted training instances can generate an accuracy value for the trained neural network model. Additionally or alternatively, the sensor suite on the additional vehicle can include a removable hardware pod which can be mounted on a variety of vehicles.
