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: 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: Techniques are described for monitoring tire conditions on an autonomous vehicle, more specifically, an autonomous truck that includes a tractor unit and a trailer. An example autonomous vehicle includes a tractor unit configured to be coupled to a trailer that comprises multiple tires. The autonomous vehicle may also include one or more infrared sensors. At least part of the one or more infrared sensors is positioned at a rear side of the tractor unit and faced towards the trailer. The one or more infrared sensors are configured to capture one or more heatmaps each representing a temperature distribution of a tire. The one or more infrared sensors are in communication with a control system that is configured to receive the temperature distribution from the one or more infrared sensors, determine a tire condition of the tire, and operate the tractor unit according to the tire condition.

Abstract: Devices, systems, and methods for redundant braking systems and architectures are described. An example method for controlling a vehicle includes receiving, by a braking system, a first set of commands generated by a primary brake controller and a primary vehicle control unit (VCU) comprising multiple processors, receiving a second set of commands generated by the primary VCU and a secondary brake controller, receiving a third set of commands generated by a secondary VCU and the primary brake controller, receiving a fourth set of commands generated by the secondary VCU and the secondary brake controller, and selecting, based on an arbitration logic, exactly one of the first, second, third, and fourth sets of commands to operate the braking system, wherein the primary VCU and the secondary VCU are configured in a master/slave architecture.

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: 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.
