Abstract: 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.

Abstract: Provided are methods, systems, and apparatuses for telematics navigation.

Abstract: A personal emergency response (PER) device may include an audio sensor that is used to enhance the operation of the PER device. The audio sensor may obtain audio data that can be used to verify whether a fall event that is detected by the PER device is a false positive signal and/or enhance the reliability of a detected fall event. In some implementations, the audio data may be used in the detection of vehicle crashes in which a user of the PER device is involved.

Abstract: 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.

Abstract: A first device may transmit a message, such as a connection request, to a second device, and the message may include a friendly name associated with the first device. A connection may be established between the first and second devices based on the message, and first data may be transmitted via the connection. The first device may generate a modified message by modifying the friendly name based on second data, and the first device may forward the modified message to a third device. The third device may evaluate the modified message to identify and extract the second data.

Abstract: Vehicle diagnostic tests may be performed by an owner of a vehicle on a self-serve basis. In one implementation, a method may include communicating, by a vehicle diagnostic device, with a vehicle through an OBD connector of the vehicle, to obtain diagnostic information relating to operation of the vehicle. The method may further include receiving instructions relating to the obtaining of the diagnostic information and playing, via a speaker associated with the vehicle diagnostic device, the instructions as audible instructions.

Abstract: A user device application transmits the device's location and unique identifier with a message requesting location information that corresponds to a vehicle associated with the user device's unique identifier. The application sends the request message over a communication network to a central computer. The central computer obtains location information corresponding to the vehicle from a device proximate the vehicle. The central computer compares the locations of the user device and telematics device and generates a location differential value corresponding to the distance between them. If the differential value meets predetermined criteria, the central computer causes an action, for example forwarding the location information corresponding to the vehicle to the requesting user device. Or, the central computer sends the requesting device a request denied message. The central computer may also deny the request when the vehicle is moving, or if the user device has requested the vehicle's location too frequently.
