System includes a controller configured to obtain one or more of a route parameter or a vehicle parameter from discrete examinations of one or more of a route or a vehicle system. The route parameter is indicative of a health of the route over which the vehicle system travels. The vehicle parameter is indicative of a health of the vehicle system. The discrete examinations of the one or more of the route or the vehicle system separated from each other by one or more of location or time. The controller is configured to examine the one or more of the route parameter or the vehicle parameter to determine whether the one or more of the route or the vehicle system is damaged. The system also includes examination equipment configured to continually monitor the one or more of the route or the vehicle system responsive to determining that the one or more of the route or the vehicle is damaged.

Vehicle control system and method

A controller may receive interface information, associated with one or more interfaces used to communicate with one or more components of a vehicle, and may receive application information associated with one or more applications configured to receive information from the one or more components via the one or more interfaces. The controller may store, based on the interface information and the application information, registration information that indicates whether the one or more applications are permitted to communicate via the one or more interfaces. The controller may receive, from an application of the one or more applications, a request for vehicle information from an interface of the one or more interfaces. The controller may verify whether the application is permitted to communicate via the interface, and may selectively route the request for the vehicle information to the interface based on verifying whether the application is permitted to communicate via the interface.

Communication system for controlling or monitoring vehicle components

A system includes an energy management system configured to be communicatively coupled with a communication system of a vehicle that travels on a trip along a route. The energy management system is configured to be removably coupled with the communication system such that the energy management system is mechanically disengageable from the communication system. The energy management system is further configured to receive data parameters from the communication system and to generate at least one of a trip plan or a control message for the vehicle based on the data parameters. The trip plan and/or the control message dictates tractive and braking efforts of the vehicle during the trip. The energy management system is configured to communicate the trip plan and/or the control message to the communication system for the communication system to implement for controlling movement of the vehicle during the trip.

Data communication system and method for communicating data in a vehicle

A processing system and method for controlling the distribution of certain types of electronic messages, such as SMS messages, instant messages, emails, etc., that are wirelessly sent to a vehicle. In one embodiment, a messaging application installed on a communication device diverts to a call center outgoing messages destined for the vehicle. Once the electronic message is properly checked and authenticated at the call center, it is wirelessly forwarded on to the vehicle where its contents can be displayed to the passengers. By controlling the distribution of these types of electronic messages to the vehicle, the processing method can reduce or mitigate the effects of unauthorized third party communications.

Processing electronic messages wirelessly sent to a vehicle

A method of establishing an alternate communication channel between a telematics unit and a central facility that includes determining that a vehicle telematics unit is unable to communicate data over a voice call using a voice channel; initiating a data call from the vehicle telematics unit to a central facility based on that determination; sending information identifying the vehicle telematics unit to the central facility over the data call; establishing a voice call from the central facility to verbally communicate with the vehicle telematics unit based on the information identifying the vehicle telematics unit; and communicating data between the central facility and vehicle telematics unit via short messaging services (SMS) messages using the voice call from the central facility.

Method of communicating voice and data transmissions for telematics applications

A method and system for local broadcasting of messages from a wireless mobile device to many others located within the same geographic area. This can be done using SMS messaging wherein a message to be broadcast is addressed to a particular designated address and, when received by a wireless carrier system, is checked to determine that it came from an authorized sender, and then is broadcasted by the wireless carrier system to a geographically-limited area within which the sending wireless mobile device is located.

A data conversion system for a vehicle includes an interface gateway device that is configured to be communicatively coupled with a data acquisition module and a client module. The data acquisition module obtains a value of a data parameter related to operation of the vehicle and communicates the value to the interface gateway device in a first message provided in a first format. The interface gateway device is configured to convert the first format of the first message into a different, second format to form a second message and to communicate the second message to the client module. The client module uses the second message to perform a function for the vehicle.

Data conversion system and method for converting data that is distributed in a vehicle

A system and method of communicating data between a vehicle and call center via a voice channel of a wireless communication system. The method carried out by the system includes the steps of: establishing a voice channel connection between a vehicle telematics unit and call center via a wireless cellular network; generating a modem signaling carrier comprising a prefix followed by a single frequency tone; sending the modem signaling carrier over the voice channel connection using an EVRC-B vocoder; establishing a data communication session over the voice channel connection in response to the modem signaling carrier; and thereafter carrying out data communications between the vehicle telematics unit and call center during the data communication session.

Modem signaling using a multitone prefix over a voice channel of a wireless communication system

A tone detector and associated method for use with EVRC-B and GSM vocoders to enable reliable detection of system connect tones over a wireless communication system. The tone detection method examines a number of sequential data frames of the signal received from the vocoder and determines that the tone is present if the spectral energy at frequencies around the tone is much higher than that at neighboring frequencies and if the calculated center frequency of the data frames is at or near the frequency of the tone.

Tone detection for signals sent through a vocoder

A method of processing global navigation satellite system (GNSS) data includes identifying one or more GNSS satellites servicing a predefined area, receiving at least one of GNSS almanac data or space-based augmentation system (SBAS) data for the satellites servicing the predefined area, determining the performance of the GNSS satellites servicing the predefined area using the almanac data or SBAS data, and applying a performance rating to the predefined area based on the performance of the GNSS satellites.

Method of processing global navigation satellite system data

A system and method for data communication over a cellular communications network that allows the transmission of digital data over a voice channel using a vocoder that monitors parameters of a Levinson Durbin recursion and then uses full rate CELP if the monitored prediction error falls to below a predetermined threshold within a pre-selected number of iterations of the recursion. The system and method encode digital data to be transmitted using a continuous signal modulation technique at a selected bit rate and one or more frequencies that are selected such that the resulting modulated carrier signal is processed by the vocoder using full rate CELP as a result of the monitored prediction error.

Method for data communication via a voice channel of a wireless communication network using continuous signal modulation

A system and method for data communication over a cellular communications network that allows the transmission of digital data over a voice channel connection using a vocoder that prevents the generation of spurious signals during transmission. The method utilizes a signaling waveform which varies in amplitude, frequency, phase, or combination thereof without exhibiting periodic nullities.
