Abstract
A system includes a processor configured to determine that a telematics control unit component temperature is above a predefined maximum temperature. The processor is also configured to send a message to a remote communication server notifying the server that packet communication will be disabled and disable packet communication, responsive to the determination. The processor is further configured to enable binary user-data-embedded SMS message handling for remote commands received from the server, responsive to disabling the packet communication.
Claims20
A system comprising:
- a vehicle processor configured to:
- determine that an onboard telematics control unit component temperature is above a predefined maximum temperature;
- responsive to the determination, (i) send a message to a remote communication server notifying the server that packet communication will be disabled and (ii) disable packet communication;
- and
- enable SMS message handling for remote vehicle commands received from the server, responsive to disabling the packet communication, wherein the SMS message includes embedded data providing instructions.
A computer-implemented method comprising:
- determining a telematics control unit component, included in a vehicle, temperature;
- sending state-change messages to a backend server, responsive to the temperature crossing a predefined threshold;
- disabling an enabled packet communication capability responsive to the temperature rising above the threshold;
- enabling a disabled packet communication capability responsive to the temperature falling below the threshold;
- and
- enabling receipt and handling of remote vehicle commands received as SMS messages including embedded control-instruction data while the packet communication capability is disabled.
A system comprising:
- a telematics control unit (TCU) processor;
- and
- a server, wherein
- the TCU processor is included in a vehicle and is configured to:
- detect an onboard modem temperature above a predefined threshold;
- responsive to the temperature, send a first message to the server, and
- disregard wake-up messages and process messages including embedded vehicle control-instruction data while the temperature remains above the threshold;
- wherein the server is configured to:
- switch messaging formats to a vehicle from wake-up to messages including embedded control-instruction data responsive to receiving the first message.
