Abstract: Methods, systems, and devices for dataset simplification of N-dimensional signals captured for asset tracking are provided. An example method involves obtaining raw data from a data source onboard an asset and determining whether obtainment of the raw data results in satisfaction of a data logging trigger. The method further involves, when the data logging trigger is satisfied, performing a dataset simplification algorithm on a target set of data within the raw data to generate a simplified set of data, wherein the target set of data contains a time-variant N-dimensional signal, N>=1, and the dataset simplification algorithm is generalized for all N>=1. The method further involves transmitting the simplified set of data to a server.

Abstract: Vehicles can employ onboard telematic monitoring devices to collect vehicle and operation data, such as for improved vehicle fleet management. Such telematic monitoring devices are dependent on power from a vehicle, such that data collection and communication can be interrupted if a telematic monitoring device is disconnected or has a poor connection. The present disclosure relates to battery devices, which provide power to telematic monitoring devices as needed in order to maintain data collection and communication, or other more limited functionality. The present disclosure also relates to systems including battery devices, and methods for operating battery devices. The present disclosure also relates to detecting temperature of batteries, as well as emergency input and messages for telematic monitoring systems.

Abstract: A traffic analysis system analyzes location data from a plurality of vehicles to determine journeys made by the vehicles. Vehicles may make one or more rest stops during a journey. The traffic analysis system compares rest periods to journey criteria to determine whether a rest period delineates the end of a journey, or whether a rest period is still within the journey. In this way, a plurality of trips can be chained together into a journey to provide more accurate analysis of traffic patterns.

Abstract: Described herein are examples of a computerized method that comprises: in response to obtaining information regarding a potential collision between a vehicle and an object, obtaining data describing the vehicle for a time period extending before and after a time of the potential collision. The method may determine a likelihood that the potential collision is a non-collision event based on the data describing the vehicle by performing one or more assessments. The assessments may include telematics monitor assessment, driver behavior assessment, road surface feature assessment, trip correlation assessment, and/or context assessment. In response to determining that the likelihood indicates that the potential collision is not a non-collision event, the method may trigger one or more actions responding to the potential collision.

Abstract: Systems and method for safe over-the-air (OTA) update of electronic control units in vehicles are provided. The OTA server determines whether an operator terminal is close to a vehicle and if so, sends a request to the operator terminal requesting confirmation for proceeding with completing a firmware update for an electronic control unit in the vehicle. In response to receiving the confirmation, the OTA server sends a request to a telematics device coupled to the vehicle to complete the firmware update.

Abstract: The present systems, devices, and methods relate to managing vehicle battery charging. Payment for charging is preauthorized, and a receipt for preauthorization is sent from a payment management device to a user device when the user device has access to internet or cellular communications. This preauthorization receipt is later sent from the user device to a charge station where internet or cellular communication is not available, to enable charging of the vehicle battery at the charge station. Another receipt is sent from the charge station to the user device after charging of the vehicle, indicating a payment amount for actual energy used to charge the battery. Later, when the user device has access to cellular or internet communications, the user device sends the receipt indicating payment amount for actual energy used to the payment management device, for final payment balancing.

Abstract: Described herein are various techniques, including a method that uses high-rate acceleration data for computing an accident score indicative of a potential collision and triggering an action in response to determining that the accident score indicates a potential collision. The method includes filtering out undesired high-rate acceleration trigger events such as noise and harsh braking events prior to determining the accident score. The accident score is based on contexts or scores computed from high-rate acceleration data, speed, and GPS data captured by a telematics monitor deployed in a vehicle.

After the expiry of the requests-off duration, sending the second request. In response to detecting a vehicle turning off event, sending a third request and receiving a third response up to a post vehicle turning off duration.

Abstract: An asset tracker deployed in an engineless vehicle and a telematics device coupled to a vehicle both send location updates to a telematics server. The asset tracker sends location updates at a faster rate upon leaving a shipping yard, for example. The telematics server associates the vehicle and engineless vehicles, determines whether they are travelling together, and sends a notification when they are not supposed to be travelling together.

Abstract: A method for inferring a status asset information from data of a first type gathered by a first asset tracking device is provided. The method includes determining that a first asset tracking device coupled to a first asset and a second asset tracking device coupled to a second asset are travelling together, that the first asset tracking device has a first operating mode, and that the second asset tracking device has a second operating mode, which is different from the first operating mode of the first asset tracking device. In response, the second asset tracking device enters into a low-power mode in which it either does not gather data of the first type or does so at a reduced rate. Status information related to the second asset may be inferred from data of the first type gathered by the first asset tracking device.
