Abstract

A system for providing updates in a vehicle includes a server device configured for providing an OTA campaign update and the vehicle. The vehicle includes a device including software to be upgraded by the over-the-air campaign update and a low voltage battery providing low voltage power. The system further includes a battery providing high voltage power and an accessory power module configured to transform the high voltage power into low voltage power and including programming to estimate an available power of the low voltage battery. The system further includes a controller monitoring the available power, comparing the available power to a threshold, and, when the available power is less than the threshold, commanding the accessory power module to transform the high voltage power to provide the low voltage electrical power. The controller further schedules receiving the update based upon the available power and updates the device with the update.

First claim

What is claimed is:

1. A system for providing updates to software in a vehicle to be updated, comprising:
a remote server device configured for providing an over-the-air campaign update to the vehicle to be updated; and
the vehicle to be updated including:
a device including software configured for being upgraded by the over-the-air campaign update;
a relatively low voltage battery providing relatively low voltage direct current electrical power;
a relatively high voltage electric vehicle battery providing relatively high voltage direct current electrical power;
an accessory power module configured to transform the relatively high voltage direct current electrical power into the relatively low voltage direct current electrical power and including programming to estimate an available power of the relatively low voltage battery;

a supervisory controller including programming to:
monitor the available power of the relatively low voltage battery;
compare the available power of the relatively low voltage battery to a threshold power level;
when the available power of the relatively low voltage battery is equal to or less than the threshold power level, command the accessory power module to transform the relatively high voltage direct current electrical power to provide the relatively low voltage direct current electrical power;
schedule receiving the over-the-air campaign update based upon the available power of the relatively low voltage battery; and
update the software of the device with the over-the-air campaign update;

wherein the remote server device includes programming to:
map a list of a plurality of available over-the-air campaign updates to be operated for a group of vehicles with situational awareness information; and
send the list of the plurality of available over-the-air campaign updates to the group of vehicles including sending a relevant portion of the list of the plurality of available over-the-air campaign updates to the vehicle to be updated;

wherein the supervisory controller further includes programming to:
monitor situational awareness information of the vehicle to be updated;
estimate available time periods in which to schedule receiving a plurality of over-the-air campaign updates corresponding to the relevant portion of the list of the plurality of available over-the-air campaign updates based upon the available power of the relatively low voltage battery and the situational awareness information; and
schedule receiving the plurality of over-the-air campaign updates based upon the available time periods.

2. The system of claim 1 , wherein the supervisory controller further includes programming to:
evaluate a situational awareness factor; and
reevaluate the estimated available power based upon the situational awareness factor.

3. The system of claim 2 , wherein evaluating the situational awareness factor includes evaluating a vehicle location, scheduling data, a feature update list, a timeline, an average power degradation, or temperature.

4. The system of claim 1 , wherein the supervisory controller further includes programming to:
monitor occurrence of a plug-in event; and
recalculate the available power of the relatively low voltage battery based upon charging performed during the plug-in event.

5. The system of claim 1 , wherein the supervisory controller further includes programming to:
monitor actual power consumption through an operational period including the available time periods;
compare the actual power consumption to a predictive power algorithm; and
when the actual power consumption exceeds power consumption predicted by the predictive power algorithm, adjust the available time periods based upon the actual power consumption.

6. A system for providing updates to software in a plurality of vehicles, comprising:
a remote server device configured for providing an over-the-air campaign update to the plurality of vehicles; and
the plurality of vehicles, each of the plurality of vehicles including:
a device including software configured for being upgraded by the over-the-air campaign update;
a relatively low voltage battery providing relatively low voltage direct current electrical power;
a relatively high voltage electric vehicle battery providing relatively high voltage direct current electrical power;
an accessory power module configured to transform the relatively high voltage direct current electrical power into the relatively low voltage direct current electrical power and including programming to estimate an available power of the relatively low voltage battery;

a supervisory controller including programming to:
monitor the available power of the relatively low voltage battery;
compare the available power of the relatively low voltage battery to a threshold power level;
when the available power of the relatively low voltage battery is equal to or less than the threshold power level, command the accessory power module to transform the relatively high voltage direct current electrical power to provide the relatively low voltage direct current electrical power;
schedule receiving the over-the-air campaign update based upon the available power of the relatively low voltage battery;
update the software of the device with the over-the-air campaign update;

wherein the remote server device includes programming to:
identify a group of vehicles within the plurality of vehicles to be updated with a same plurality of over-the-air campaign updates;
evaluate the available power of the relatively low voltage battery of each of the group of vehicles; and
schedule transmission of the plurality of the over-the-air campaign updates to each of the group of vehicles at simultaneous times based upon the evaluating.

7. The system of claim 6 , wherein the supervisory controller further includes programming to:
evaluate a situational awareness factor; and
reevaluate the estimated available power based upon the situational awareness factor.

8. The system of claim 7 , wherein evaluating the situational awareness factor includes evaluating a vehicle location, scheduling data, a feature update list, a timeline, an average power degradation, or temperature.

9. The system of claim 7 , wherein the remote server device includes programming to:
map a list of a plurality of available over-the-air campaign updates to be operated for the plurality of vehicles; and
send the list of the plurality of available over-the-air campaign updates to the plurality of vehicles including sending a relevant portion of the list of the plurality of available over-the-air campaign updates to each of the plurality of vehicles.

10. The system of claim 9 , wherein the supervisory controller further includes programming to:
estimate available time periods in which to schedule receiving a plurality of over-the-air campaign updates corresponding to the relevant portion of the list of the plurality of available over-the-air campaign updates based upon the available power of the relatively low voltage battery and the situational awareness factor; and
schedule receiving the plurality of over-the-air campaign updates based upon the available time periods.

11. The system of claim 10 , wherein the supervisory controller further includes programming to:
monitor actual power consumption through an operational period including the available time periods;
compare the actual power consumption to a predictive power algorithm; and
when the actual power consumption exceeds power consumption predicted by the predictive power algorithm, adjusting the available time periods based upon the actual power consumption.
