摘要： Techniques are described for determining weight distribution of a vehicle. A method of performing autonomous driving operation includes receiving two sets of values from two sets of sensors, where a first set of sensors measure weights or pressures applied on axles of a vehicle, and where a second set of sensors measure pressures in tires of the vehicle. The method performs an error detection and removal operation to remove or filter out any erroneous values from the two sets of values to obtain two sets of filtered values. The method determines one or more values that describe a weight or pressure applied on the axle to obtain the weight distribution of the vehicle based on the first set of filtered values or the second set of filtered values. Based on the obtained weight distribution of the vehicle, the method can determine a driving operation of the vehicle.

摘要： 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.

摘要： 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.

摘要： Disclosed are devices, systems and methods for using a rotating camera for vehicular operation. One example of a method for improving driving includes determining, by a processor in the vehicle, that a trigger has activated, orienting, based on the determining, a single rotating camera towards a direction of interest, and activating a recording functionality of the single rotating camera, where the vehicle comprises the single rotating camera and one or more fixed cameras, and where the single rotating camera provides a redundant functionality for, and consumes less power than, the one or more fixed cameras.

摘要： Described are devices, systems and methods for real-time remote control of vehicles with high redundancy. In some embodiments, two copies of at least one control command are received using two different wireless communication protocols, and are compared. The at least one control command is executed when the two copies are in agreement, but is rejected when the two copies differ. In other embodiments, additional wireless communication protocols may exist to provide a redundant mode of communication when one of the two different wireless communication protocols are unavailable. In yet other embodiments, redundant GPS units may be used to determine availability of any of the communication protocols, and relevant control commands may be downloaded in advance to circumvent the lack of coverage.

摘要： 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.

摘要： Techniques are described for measuring angle and/or orientation of a rear drivable section (e.g., a trailer unit (308) of a semi-trailer truck) relative to a front drivable section (e.g., a tractor unit (202) of the semi-trailer truck) using an example rotary encoder assembly (304, 400). The example rotary encoder assembly (304, 400) comprises a base surface (404); a housing (402, 404) that includes a second end (402B) that is connected to the base surface (404) and a first end (402B) that is at least partially open and is coupled to a housing cap (414) and a rotary encoder (312, 408) that is located in the housing (402, 404) in between the base surface (404) and the housing cap (414), where the rotary encoder (312, 408) includes a rotatable shaft (424) that protrudes from a first hole (306, 422, 426) located in the housing cap (414), and where a top of the rotatable shaft (424) located away from the rotary encoder (312, 408) is coupled to magnet(s).
