    Abstract: A control system for an autonomous vehicle includes a time sensitive network switch and a control system interface. The control system interface includes a primary processing unit, a secondary processing unit, and a fault detection module. The control system receives a trajectory of an autonomous vehicle. The fault detection module detects a fault condition with the primary processing unit and prevents the primary processing unit from transmitting a primary control signal in response to the fault condition. The primary control signal is for autonomous control of the autonomous vehicle.

    Abstract: A LIDAR device for a vehicle includes an integrated chip. The integrated chip includes a substrate layer, a cladding layer, a waveguide, a scattering array, and a reflector layer. The cladding layer is disposed on the substrate layer to form an interface with the substrate layer. The waveguide is disposed within the cladding layer and configured to route an infrared optical field. The scattering array is disposed within the cladding layer between the waveguide and the interface and perturbs the infrared optical field and scatters the infrared optical field into a first beam propagating toward a surface of the cladding layer and into a second beam propagating towards the interface. The reflector layer is disposed within the cladding layer between the waveguide and the surface of the cladding layer to reflect the first beam towards the interface.

    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 may include a transceiver, a first device including a laser source configured to generate a beam, and one or more optical components, a second device including one or more analog-to-digital converters (ADCs), and a processor configured to alternately turn on the first device and turn on the transceiver. The first device may be configured to generate, based on the beam, an optical signal associated with a local oscillator (LO) signal. The transceiver may be configured to transmit the optical signal to an environment, in response to transmitting the optical signal, receive a returned optical signal that is reflected from an object in the environment, and pair the returned optical signal with the LO signal to generate an electrical signal. The second device may be configured to generate, based on the electrical signal, a digital signal.

    Abstract: Example methods for multistage autonomous vehicle motion planning include obtaining sensor data descriptive of an environment of the autonomous vehicle; identifying one or more objects in the environment based on the sensor data; generating a plurality of candidate strategies, wherein each candidate strategy of the plurality of candidate strategies comprises a set of discrete decisions respecting the one or more objects, wherein generating the plurality of candidate strategies includes: determining that at least two strategies satisfy an equivalence criterion, such that the plurality of candidate strategies include at least one candidate strategy corresponding to an equivalence class representative of a plurality of different strategies that are based on different discrete decisions; determining candidate trajectories respectively for the plurality of candidate strategies; and initiating control of the autonomous vehicle based on a selected candidate trajectory.
