摘要： The present disclosure relates to a method for estimating a position of an object by determining a distance from the object to a sensor module and determining a starting reference space indicative of a position estimate of the object. The method also includes performing a plurality of successive division operations of the starting reference space for improving the position estimate of the object until a predetermined criterion is met. A division operation includes dividing the current reference space into subspaces. Further, the method includes assigning, on each of the subspaces, a confidence factor indicating a confidence that the object is positioned in the respective subspace, and selecting a new reference space from the subspaces based on the confidence factors. The method further comprises determining the position of the object based on the new reference space according to the last division operation.

摘要： A smart anchor-based position estimation method and apparatus are disclosed. The position estimation method, performed by a position estimation apparatus, includes: identifying one or more line-of-sight (LOS) anchors from among one or more anchors mounted in a vehicle; selecting reference anchors from among the one or more LOS anchors; and estimating a position of a tag based on a number of the reference anchors. The reference anchors are selected based on a rate of formation of an ultra-wideband (UWB) link to the tag and accuracy of the estimated position of the tag.

摘要： A method for detecting a change in location of at least one wheel of a motor vehicle, the vehicle having at least one central processing unit, one wheel unit which includes an electronic assembly of sensors and which is mounted on the wheel, and one bidirectional communications assembly. The method notably includes a first comparison step, during which a first evaluation pattern is compared with a first reference pattern to determine whether the location of the wheel has changed, the patterns being representative of the effective location of the wheel unit in the motor vehicle.

摘要： A positioning system has a central unit receiving identity and timing information; and based thereon determines a respective position in an area of each of a set of entities. Each entity carries a mobile unit repeatedly transmitting a radio message including the identity information. The positioning system also contains at least three base stations, each receiving the radio messages from the mobile units; and based thereon, forwards the identity and timing information to the central unit. During a measurement period, the central unit registers positions of the entities as a trace for each mobile unit. The central unit checks whether, during the measurement period a first predefined number of traces are interrupted during a first threshold interval, and the predefined number of traces are interrupted in a first zone, which exceeds a first threshold size. If so, a capacity alarm with respect to the first zone is generated.

摘要： A method and network node for differential matched summed antenna positioning are disclosed. According to one aspect, a method includes summing sequential uplink data signals at each of a plurality of antennas of the network node to produce a plurality of antenna signal sums. The method also includes selecting one of the antenna signal sums to be used as a reference antenna signal sum. A channel impulse response is determined for each of a plurality of other antennas by cross correlating the reference antenna signal sum with the others of the plurality of antenna signal sums. The method further includes estimating a time difference of arrival from the channel impulse responses of the plurality of antennas, and estimating an error of the estimated time difference of arrival of each antenna. A position of a wireless device is determined using the estimated time differences of arrival.
