    Abstract: Aspects of the disclosure involve a collision mitigated braking system employed in vehicles operating in a self-driving (autonomous) mode. Collision mitigated braking provides redundancy to the vehicle's main driving system in emergency situations. The collision mitigated braking system is configured to cause the vehicle to come to a stop when an imminent collision is perceived and the main driving system has not initiated a braking maneuver. A perception component employs information received from vehicle sensors, analyzing the sensor data to identify nearby objects of interest that are determined to be in the vehicle's path or that could otherwise collide with the vehicle. A control component evaluates the objects of interest to determine whether immediate braking is required. If this is the case and the main driving system has not begun to brake, the control component causes the vehicle to perform immediate braking to avoid a possible collision.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating unmapped U-turn predictions using a machine learning model. One of the methods includes obtaining features of an agent travelling on a roadway. One or more unmapped U-turn regions in a vicinity of the agent on the roadway are identified. For each of the unmapped U-turn regions and from at least the features of the agent, a respective likelihood score that represents a likelihood that the agent intends to make an unmapped U-turn at the unmapped U-turn region is generated. Based on the respective likelihood scores, one or more of the unmapped U-turn regions are selected. For each selected unmapped U-turn region, data specifying a candidate future trajectory in which the agent makes the unmapped U-turn at the selected unmapped U-turn region is provided as a possible future trajectory for the agent.

    Abstract: A method includes identifying map data comprising driving constraint data for a route of an autonomous vehicle (AV), the map data being of a road network associated with the route of the AV, the driving constraint data being based on physical vehicle data. The method further includes, while the AV is travelling the route, identifying current environmental sensing data for a portion of the route. The method further includes causing, based on the map data comprising the driving constraint data for the route and the current environmental sensing data associated with the portion of the route, the AV to travel the portion of the route.

    Abstract: The technology relates to detecting and responding to processions. For instance, sensor data identifying two or more objects in an environment of a vehicle may be received. The two or more objects may be determined to be disobeying a predetermined rule in a same way. Based on the determination that the two or more objects are disobeying a predetermined rule, that the two or more objects are involved in a procession may be determined. The vehicle may then be controlled autonomously in order to respond to the procession based on the determination that the two or more objects are involved in a procession.

    Abstract: A sensing device includes a stationary portion and a rotating portion. The rotating portion is spaced apart from the stationary portion by a gap and is configured to rotate relative to the stationary portion. The rotating portion includes one or more sensors that generate data. A communication interface in the rotating portion is configured to encode the data with error correction codes to provide encoded data, modulate a radio frequency (RF) signal that includes a plurality of sub-carriers with the encoded data to provide a data-modulated RF signal (e.g., an orthogonal frequency-division multiplexing (OFDM) signal), and transmit the data-modulated RF signal to the stationary portion via a wireless data transformer. The wireless data transformer includes a first conductive structure in the stationary portion and a second conductive structure in the rotating portion. The first and second conductive structures are inductively coupled together across the gap.

    Abstract: The technology relates to determining a source of a horn honk or other noise in an environment around one or more self-driving vehicles. Aspects of the technology leverage real-time information from a group of self-driving vehicles regarding received acoustical information. The location and pose of each self-driving vehicle in the group, along with the precise arrangement of acoustical sensors on each vehicle, can be used to triangulate or otherwise identify the actual location in the environment for the origin of the horn honk or other sound. Other sensor information, map data, and additional data can be used narrow down or refine the location of a likely noise source. Once the location and source of the noise is known, each self-driving vehicle can use that information to modify current driving operations and/or use it as part of a reinforcement learning approach for future driving situations.

    Abstract: Aspects of the disclosure provide controlling an autonomous vehicle. For example, a first trajectory generated by a first planning system may be received. A portion of the first trajectory may be input into a second planning system. A second trajectory generated by the second planning system based on the portion of the first trajectory may be received. The second trajectory may be used to determine whether to validate the first trajectory, and when the second trajectory is determined to be validated, the autonomous vehicle may be enabled to be controlled based on the first trajectory.

    Abstract: Example embodiments relate to low elevation side lobe antennas with fan-shaped beams. An example radar unit may include a radiating plate having a first side and a second side with an illuminator, a waveguide horn, a waveguide opening, and a radiating sleeve extending into the first side of the radiating plate. The waveguide opening is positioned on the first end of the first side and the radiating sleeve is positioned on the second end of the first side. The radar unit also includes a metallic cover coupled to the first side of the radiating plate such that the metallic cover and the radiating plate form waveguide structures. The waveguide horn is configured to receive, from an external source, electromagnetic energy provided through the waveguide opening via a first waveguide and provide a portion of the electromagnetic energy to the illuminator via a second waveguide such that the portion of the electromagnetic energy radiates off the illuminator and through the radiating sleeve into an environment of the radar unit as one or more radar signals.
