Abstract: Techniques are described for estimating road friction between a road and tires of a vehicle. A method includes receiving, from a temperature sensor on a vehicle, a temperature value that indicates a temperature of an environment in which a vehicle is operated, determining a first range of friction values that quantify a friction between a road and tires of a vehicle based on a function of the temperature value and an extent of precipitation in a region that indicate a hazardous driving condition, obtaining, from the first range of friction values, a value that quantifies the friction between the road and the tires of the vehicle, where the value is obtained based on a driving related behavior of the vehicle, and causing the vehicle to operate on the road based on the value obtained from the first range of friction values.

Abstract: An example sensor system for use with a vehicle includes a first group of sensing devices that are associated with an essential level of autonomous operation of the vehicle. The first group of sensing devices are configured and intended for continuous use while the vehicle is being autonomously operated. The sensor system further includes a second group of sensing devices that are associated with a non-essential level of autonomous operation of the vehicle. For example, the second group of sensing devices are configured to be redundant to and/or to enhance the performance of the first group of sensing devices. The second group operates in response to certain conditions being determined during autonomous operation of the vehicle. The sensor system further includes a plurality of assemblies attached to the vehicle. Each assembly includes two or more sensing devices from the first group and/or the second group.

Abstract: The angle of a trailer with respect to a tow vehicle is an important parameter to the stability of the vehicle and trailer. A tow vehicle pulling a trailer in a straight line is generally more stable than when the vehicle is turning. While turning, the angle between the tow vehicle and the trailer is not a straight line but is another angle depending on how sharply the tow vehicle is turning. To safely operate a vehicle towing a trailer, for a given steering input and speed, there is a maximum angle between the tow vehicle and trailer whereby exceeding the angle causes instability and may cause the trailer or tow vehicle to roll over or jackknife. Accordingly, the angle between the trailer and tow vehicle must be determined to ensure the vehicle and trailer will continue to be in control.

Abstract: An autonomous vehicle (AV) includes features that allows the AV to comply with applicable regulations and statues for safe operation. An AV may operate in conjunction with an oversight system, such as when coordinating a fleet of autonomous vehicles. One aim of AV technologies is to provide vehicles that can safely navigate towards a destination with limited or no driver assistance. AVs or other types of vehicles carrying goods may be subject to theft and other undesired disturbances. Systems, apparatus, and methods are provided to ensure a chain of custody for cargoes in an AV. Numbered seals are attached to the doors of an AV to detect unauthorized door open operations. Unauthorized vehicle stops are also detected based on position tracking information of the AV. Changes in cargo weight can also be detected.

Abstract: Techniques are described for reducing the memory load associated with point cloud data. An example method includes transmitting a light pulse, detecting, by a light detector, a plurality of returns of the light pulse, producing a point cloud comprising a plurality of points associated with the plurality of returns, and generating a reduced set of points associated with the plurality of returns by removing a subset of the plurality of points from the point cloud. The reduced set of points can then be used by autonomous vehicle systems to efficiently map a surrounding environment without significantly reducing accuracy.
