Abstract

A telematics control unit comprising a transceiver configured to receive a message from a vehicle module during a sleep mode, the message requesting the telematics control unit to output information via a telecommunications network. The telematics control unit also includes a processor configured to determine whether to output the information or delay the output of the information based upon the message, and output the information to the telecommunications network, or delay outputting the information until the telematics control unit enters a full-power mode or a wake-up cycle.

Claims

1. A body control module (BCM) in a vehicle, comprising:

a transceiver for receiving an alert from a remotely located device during a sleep mode of a telematics control unit (TCU) of the vehicle, the transceiver in communication with the TCU and the remotely located device utilizing a vehicle bus, the alert requesting, via the transceiver, the TCU to output information to a telecommunications network;

a processor configured to;

send a request to the TCU to delay output of the information to the telecommunications network in response to the alert; and

after outputting the information, send a request to the TCU to activate a power mode of the TCU corresponding to the alert.

2. The body control module of claim 1, wherein the processor is configured to update a firmware version of the BCM.

3. The telematics control unit of claim 2, wherein the update to the firmware version of the BCM updates an alert strategy of the BCM and the TCU.

4. The telematics control unit of claim 2, wherein the update to the firmware version of the BCM is performed via a wireless connection.

5. The telematics control unit of claim 2, wherein the alert notifies a user of a plug status of a vehicle battery.

6. A control unit, comprising:

a vehicle transceiver receiving from a vehicle controller an alert including a short-message service (SMS) and content related to vehicle functionality;

a processor configured to, in response to the content and a charge-level of a vehicle battery;

(1) output of the alert and the SMS to a telecommunications network utilizing a wireless transceiver;

(2) activate a power mode of the control unit corresponding to the alert after outputting the alert and the SMS.

7. The control unit of claim 6, wherein the vehicle controller includes a body control module.

8. The control unit of claim 6, wherein the processor is further configured to output the alert during a wake-up cycle of the control unit.

9. The control unit of claim 6, wherein the processor is further configured to update a firmware version of the control unit.

10. The control unit of claim 9, wherein the update to the firmware version of the control unit updates an alert strategy of the control unit.

11. The control unit of claim 9, wherein the update to the firmware version of the control unit is performed via a wireless connection.

12. The control unit of claim 6, wherein the alert is a performance alert of a charging system of the battery.
