Appl. No.:

17/672119

Inventors:

- Mountain View CA, US
Felix Jose Alvarez Rivera - Tarzana CA, US
Roger Best - Carlsbad CA, US

International Classification:

B60S 1/38
B60S 1/60
B60S 1/34
B60S 1/56
B60S 1/08

Abstract:

The disclosure provides for a wiper system for cleaning a surface of a sensor housing, such as a sensor housing positioned on top of a vehicle. The wiper system includes a plurality of windows spaced around a sensor housing, and a plurality of wipers positioned around the sensor housing, each of the wipers includes a wiper blade configured to clean a corresponding window of the plurality of windows. The wiper system further includes a drive system including a moveable part coupled to a motor. The motor is configured to drive the drive system to simultaneously rotate the plurality of wipers around the sensor housing such that the plurality of wipers remove debris from the plurality of windows.

Abstract:

The disclosure relates to determining whether an optical interferent is located on a sensor window and providing a way to identify and discard erroneous sensor data. An example system includes a housing, having a first sensor window and a second sensor window, a laser light source, and an optical sensor. The first window has a first property for deflecting water, and the second window has a second property for deflecting water different from the first property. The source is configured to generate a beam of light through the first window. One or more processors are configured to receive sensor data from the optical sensor and determine that an optical interferent is located on a surface of at least one of the first window and the sensor window based on a comparison between sensor data corresponding to the first window and sensor data corresponding to the second window.

Abstract:

The technology relates to autonomous vehicles that use a perception system to detect objects and features in the vehicle's surroundings. A camera assembly having a ring-type structure is provided that gives the perception system an overall 360 field of view around the vehicle. Image sensors are arranged in camera modules around the assembly to provide a seamless panoramic field of view. One subsystem has multiple pairs of image sensors positioned to provide the overall 360 field of view, while another subsystem provides a set of image sensors generally facing toward the front of the vehicle to provide enhanced object identification. The camera assembly may be arranged in a housing located on top of the vehicle. The housing may include other sensors such as LIDAR and radar. The assembly includes a chassis and top and base plates, which may provide EMI protection from other sensors disposed in the housing.

International Classification:

B60R 21/0134
B60R 21/231

Abstract:

Aspects of the disclosure relate to airbag systems for vehicles. The airbag systems may reduce the secondary impact forces felt by an object upon rebounding from an initial impact with an external airbag by encasing or substantially surrounding the pedestrian with the external airbag. The airbag system may include an initial impact airbag and a secondary impact airbag, wherein the secondary impact airbag is configured to reduce injury caused by a secondary impact of an object upon after an initial impact of the object with the initial impact airbag. The initial impact airbag may be configured to be deployed at a location where the object is predicted to collide with the vehicle. The secondary impact airbag may comprise one or more arms configured to surround the object upon the initial impact.
