An apparatus for collecting feature data includes a memory configured to store, for each of vehicles, a mileage of the vehicle or the amount of feature data transmitted by the vehicle and representing a feature related to travel of the vehicles; and one or more processors configured to set a transmission condition for permitting transmission of the feature data for each of the vehicles so that, of the vehicles, the transmission condition for a vehicle with a lower mileage or a vehicle having transmitted a smaller amount of the feature data is more relaxed, and notify each of the vehicles via a communication circuit of a collection instruction to instruct the vehicle to collect the feature data under the transmission condition set for the vehicle.

A system for collecting traffic information includes a vehicle having at least one sensor for collecting dead reckoning (DR) information, and a global positioning system (GPS) receiver configured to receive GPS information, and a server that maps the DR information and the GPS information to a server map to generate first map matching information, and collects the first map matching information as the traffic information when it is determined that a version of a software platform of the vehicle is a latest version and all the DR information and the GPS information are received.

Various disclosed embodiments include illustrative systems, vehicles, and methods. In an illustrative embodiment, a system includes a sensor configured to generate route information, and a control unit. The control unit includes a processor in signal communication with the sensor and a memory configured to store computer-executable instructions. The computer-executable instructions are configured to cause the processor to receive the generated route information, generate a wheel signal responsive to the received route information indicating a change in wheel engagement status, and output the wheel signal to a disconnect.

An apparatus for collecting feature data includes a memory configured to store map information including a probability distribution of reliability indicating how likely a feature related to travel of vehicles exists as a function of position; and one or more processors configured to store feature data indicating the position of the feature in the memory whenever receiving the feature data from any of one or more vehicles via a communication circuit, update the probability distribution of reliability indicating how likely the feature exists as a function of position, based on the position of the feature indicated by each of one or more pieces of received feature data, and transmit an instruction to stop collecting the feature data to the one or more vehicles via the communication circuit for a feature regarding which the extent of the updated probability distribution is not greater than a predetermined threshold.

An apparatus receives a plurality of instances of map update data during a time window. Each instance is associated with a respective geographic region of a plurality of defined geographic regions. The apparatus determines, for the time window, region rankings for the plurality of defined geographic regions. A region ranking is determined based on a volume measure, a measure of map update activity, a measure of inaccurate activity, a general priority weight, and/or an interest density corresponding to the respective geographic region. The apparatus determines, for the time window, respective ranking ranges for a plurality of data buckets and assigns respective instance rankings to the instances of map update data. The instances are assigned to data buckets based on the instance rankings and ranking ranges. The apparatus ingests the instances based on the respective data buckets to cause a digital map maintained by the apparatus to be updated.

A system and method for tracking the position of a smart plug on a marine vehicle is provided. Generally, the system and method of the present disclosure are designed to generate indicia used to alert a user of the position of the smart plug on a marine vehicle so that the user may properly position the smart plug on the marine vehicle prior to launching said marine vehicle in a body of water. The system generally comprises a smart plug, a plug sensor, a processor operably connected to the plug sensor, and a non-transitory computer-readable medium coupled to the processor and having instructions stored thereon. In some preferred embodiments, a computing device having a user interface may be operably connected to the processor. At least one sensor of the smart plug collects data that may be used by the system to alert a user to secure the smart plug in the drain hole.

Disclosed embodiments include systems, vehicles, and methods for tracking off-road travel. In an illustrative embodiment, a system includes a computing device having computer-readable media storing computer-executable instructions configured to cause the computing device to monitor a vehicle location. The vehicle location is identified on map data for an area encompassing the location and including road data for recognized roads in the area. Off-road travel is detected in response to determining that the vehicle location is outside of the recognized roads. Travel data is recorded representing the off-road travel of the vehicle.

A method, a device and a system for perceiving a multi-site roadbed network are provided. The method includes: constructing a global grid map of the roadbed network that is marked with a position of the system for perceiving at least two roadbed base stations and a perceived range of the system; receiving the detected target list transmitted by each of the systems for perceiving at least two roadbed base stations, where the detected target list is the set of the preset detected targets; according to the position of each system for perceiving the roadbed base station, indexing into the global grid map the detected target list transmitted by each system for perceiving the roadbed base station to generate a global tracking list; and tracking the preset detected target in the detected target list transmitted by the system for perceiving the roadbed base station according to the global tracking list.

The invention relates to a method for ergonomically representing virtual information in a real environment, including the following steps: providing at least one view of a real environment and of a system setup for blending in virtual information for superimposing with the real environment in at least part of the view, the system setup comprising at least one display device, ascertaining a position and orientation of at least one part of the system setup relative to at least one component of the real environment, subdividing at least part of the view of the real environment into a plurality of regions comprising a first region and a second region, with objects of the real environment within the first region being placed closer to the system setup than objects of the real environment within the second region, and blending in at least one item of virtual information on the display device in at least part of the view of the real environment, considering the position and orientation of said at least one part of the system setup, wherein the virtual information is shown differently in the first region than in the second region with respect to the type of blending in the view of the real environment.
