摘要:
A system comprises a weather data network configured receive a severe weather profile including severe weather duration data, severe weather geographic boundary data, and severe weather type data. The system receives an automotive sensor profile for at least one individual vehicle including individual vehicle geographic location data. The system determines and stores a vehicle exposure profile for the at least one individual vehicle including proximity of said individual vehicle geographic location data to the severe weather geographic boundary data.

A computing device may execute a routing application to perform operations including identifying a contextual parameter indicative of a quality preference for routing over segments of geographic mapping data, weighing the segments of geographic mapping data according to traffic score information indicative of the presence of the contextual parameter over the respective segments determined based at least in part on vehicle diagnostic data, and determining a suggested route for a vehicle from a current location to a destination location over the weighed segments of geographic mapping data based on the contextual parameter. The device may be further configured to receive a route request including the destination location for the vehicle; and display the route for the vehicle on a map including indications of the quality of the segments along the suggested route. To improve the routing, learning heuristics identify what diagnostic data variables correlate with presence of which contextual parameters.
摘要:
A system and method for generating and displaying a video animation or replay of a user's drive or run using data from sensors, mapping data, manufacturer data, environmental data, and/or user data. The video replay shows an avatar representing the user or the user's vehicle and may also show the surrounding environment through which the user traveled. The video replay may be used for entertainment, instruction, insurance, or law enforcement purposes, for example.

A network device associates a fleet vehicle with a driver of it. The network device receives customer input associating a group of media access control (MAC) addresses of portable devices with driver identifiers and stores, in a memory, the MAC addresses associated with the driver identifiers. The network device also receives, from a vehicle telematics unit, a vehicle identifier of a vehicle connected to the vehicle telematics unit and a MAC address of a particular portable device proximate the vehicle. Based on the MAC address of the particular portable device, the network device associates a particular driver identifier and the vehicle identifier. The vehicle telematics unit may determine that driver is no longer driving when it can no longer detect a signal from the particular portable device that was proximate the vehicle.

Modular auxiliary processor circuitry, capable of performing telematics services, including wireless communications, diagnostic assessment and reporting, location based services, and internetworking, couples with a vehicle head unit through an auxiliary processing module interface. When so coupled, the auxiliary processing module circuitry can perform tasks, services, functions, and aspect that a lower-capability processor of the head unit cannot perform as quickly or as efficiently, if at all. When the auxiliary processor module is coupled and active, its display output can couple to a display device either permanently fixed in the vehicle, or portable and mobile with respect to the vehicle, through conductors or a wireless link. When the auxiliary processor circuitry's output couples to the display device, software running on the head unit, or the auxiliary processor module, may decouple the head unit from the display device unless a user interface requests its services, such as tuning an AM/FM radio circuit.
摘要:
Traffic at an intersection, or other portion of a road, is detected, and the stop/go traffic signal apparatus at the intersection, or other portion is controlled based on vehicle types in the detected traffic. A vehicle type may be determined based on information collected by that vehicle's onboard telematics unit, or with a user's device in communication therewith. An input may be received from a user device, onboard the vehicle, to request changing the current stop/go configuration of the traffic signal. The request may be processed based on the determined vehicle type to determine whether or nor to change the traffic signal in response to the request. The request may be accompanied by an offer of money, and if the request is not granted, the user device may forward another request associated with a different offer.
摘要:
A vehicle head unit may receive a request, from a user device and by the head unit, to establish communication with a control device of a vehicle. The control device may be in communication with the head unit via a vehicle communication network associated with the vehicle. The head unit may establish communication between the user device and the control device based on the received request. The head unit may forward a message between the user device and the control device based on the established communication. The message may be forwarded between the user device and the control device via the head unit.
摘要:
A mobile device in, or at, a vehicle sends a vehicle status message to a remote host upon occurrence of a trigger event, such as turning off the vehicle's engine. The remote host processes the vehicle status message and determines whether it can access, or find, content that is associated with location information contained in the vehicle status message. If so, the remote host forwards the content in a content message to a user device, which may or may not be the device that transmitted the vehicle status message. The remote host typically associates the user device with the vehicle, or mobile device therein, from which the vehicle status message emanated. Thus, the user device receives content corresponding to the location of the vehicle when the trigger event occurred. The content may include advertising, product promotion, tourist information, weather, traffic, or other information relevant to the trigger event occurrence location.

Upon initial boot-up, a telematics device receives a PID map in response to a PID map request. The TCU may send multiple PID map requests for different mode and PID combinations over a vehicles communication bus, and then may append each received PID map to the already-received PID maps. The multiple PID maps appended to one another form a composite bit value, or composite PID map. The composite PID map is processed according to a hash algorithm, resulting in a pseudo-VIN. Upon subsequent boot-ups of the TCU, the TCU sends the multiple PID map requests over the vehicle's bus and generates a pseudo VIN following the same steps as it did at initial boot-up. The TCU compares the currently generated pseudo-VIN to the initial pseudo VIN; if it determines a mismatch, it sends a notification to an interested third party that indicates improper usage of the TCU.
摘要:
A filter processes acceleration magnitude signals from an accelerometer device to output spectral content related to walking and running. A device containing the accelerometer determines steps by qualitatively analyzing the processed acceleration signals to determine whether increased acceleration magnitude results from a step impact from running or walking activity. The device may analyze the acceleration signals to determine crossings of an axis at zero magnitude, which crossings typically correspond to a person's foot impacting the ground, and may analyze the period between the zero crossings. The step count can indicate whether the device, in a height determination mode, is moving in a vehicle; if analysis of accelerometer signals indicates no stepping or running, but another circuit of the device indicates rapid movement, the device assumes it is moving in a vehicle, and resets a height above ground value to zero upon determining resumption of walking or running activity.
