Power management system
A vehicle communication system facilitates hands-free interaction with a mobile device in a vehicle or elsewhere. Users interact with the system by speaking to it. The system processes text and processes commands. The system supports wireless technology for hands-free use. The system handles telephone calls, email, and SMS text messages. The user can customize the device via a user profile stored on an Internet web server. The system also includes a plurality of power conservation features.
1. A method for controlling power consumption in a vehicle communication system including the steps of:
a) monitoring global positioning system-based positional movement of a control unit in a vehicle in a LOW POWER state, the control unit having an OFF state, an ON state, and the LOW POWER state, and the control unit being operable to communicate wireles sly with a mobile communication device;
b) monitoring accelerometer-based positional movement of the control unit in the LOW POWER state; and
c) entering the ON state from the LOW POWER state in response to detection of movement in said step (a), said step (b), or both.
2. The method of claim 1 wherein said step c) includes entering the ON state from the LOW POWER state in response to detection of movement in said step (a).
3. The method of claim 1 wherein said step c) includes entering the ON state from the LOW POWER state in response to detection of movement in said step (b).
4. The method of claim 1 wherein the mobile communication device is a cell phone.
5. A method for controlling power consumption in a vehicle communication system including the steps of:
a) monitoring vehicle power bus activity while a control unit is in a LOW POWER state;
b) identifying a power spike on the vehicle power bus as a vehicle ignition start condition;
c) identifying a repeated pattern of signal noise on the vehicle power bus as a vehicle running condition; and
d) commanding the control unit to enter an ON state in response to said step (b), said step (c), or both, the control unit being operable to communicate wirelessly with a mobile communication device.
6. The method of claim 5 , wherein said step (a) is performed via a vehicle lighter socket.
7. The method of claim 5 , further including the step of:
e) receiving a wireless command signal via at least one wireless communication module; and
f) commanding the control unit to enter the ON state from a LOW POWER STATE in response to said step (e).
8. The method of claim 5 further including the step of:
e) commanding the control unit to enter the OFF state in response to a predetermined period of inactivity.
9. The method of claim 5 wherein said step d) includes commanding the control unit to enter an ON state from the LOW POWER state in response said step (b).
10. The method of claim 9 wherein said step d) includes commanding the control unit to enter an ON state from the LOW POWER state in response said step (c).
11. The method of claim 10 wherein the mobile communication device is a cell phone.
12. A method for controlling power consumption in a vehicle communication system including the steps of:
a) monitoring global positioning system-based positional movement of a control unit in a vehicle in a LOW POWER state, the control unit having an OFF state, an ON state, and the LOW POWER state, and the control unit being operable to communicate wireles sly with a mobile communication device;
b) monitoring accelerometer-based positional movement of the control unit in the LOW POWER state;
c) monitoring vehicle power bus activity while the control unit is in a LOW POWER state;
d) identifying a power spike on the vehicle power bus as a vehicle ignition start condition;
e) identifying a repeated pattern of signal noise on the vehicle power bus as a vehicle running condition;
f) detecting environmental stimuli, wherein the environmental stimuli includes light or sound;
g) entering the ON state from the LOW POWER state in response to detection of movement in said step (a) or in said step (b), or in response to said step d), or in response to said step e), or in response to said step f).
13. The method of claim 12 wherein the mobile communication device is a cell phone.
