Smart vehicle fire warning system

A system comprising:

• one or more vehicle sensors of a vehicle, the one or more vehicle sensors configured to obtain sensor data pertaining to the vehicle and its surroundings, including preliminary sensor data, and further including additional sensor data of a plurality of different modalities, including tire pressure monitoring sensor data, ultrasonic sensor data, exterior temperature sensor data, and interior temperature sensor data;
• and
• a processor that is coupled to the one or more vehicle sensors and that is configured to at least facilitate:
• determining, using the preliminary sensor data, whether the vehicle is parking at a parking lot;
• and
• when it is determined that the vehicle is parking in a parking lot, then:
• determining a confidence level as to whether a fire event is occurring within the parking lot, using the additional sensor data, wherein the confidence level is based on each of the plurality of different modalities, including the tire pressure monitoring sensor data, the ultrasonic sensor data, exterior temperature sensor data, and the interior temperature sensor data, wherein the confidence level is selected from one of the following:
• a high confidence level that is consistent with the following:
• (a) a high noise level of the ultrasonic sensor data that is greater than a noise level threshold and that lasts for more than a predetermined amount of time;
• a high exterior temperature sensor data value that is greater than a first temperature threshold;
• (c) a high TPMS value sensor data 406 value that is greater than the first temperature threshold per second;
• and (d) a high internal temperature sensor data value that is greater than the first temperature threshold;
• a medium confidence level that is consistent with the following:
• (a) the high noise level of the ultrasonic sensor data that is greater than the noise level threshold and that lasts for more than the predetermined amount of time;
• (b) a medium exterior temperature sensor data value that is less than the first temperature threshold and greater than a second temperature threshold;
• (c) a medium TPMS value sensor data value that is less than the first temperature threshold and greater than the second temperature threshold;
• and (d) a medium internal temperature sensor data value that is less than the first temperature threshold and greater than the second temperature threshold;
• and
• a low confidence level that is consistent with the following:
• (a) a high noise level of the ultrasonic sensor data but that lasts for less than the predetermined amount of time;
• (b) a low exterior temperature sensor data value that is less than the second predetermined threshold;
• (c) a low TPMS value sensor data value that is less than the second predetermined threshold per second;
• and (d) a low internal temperature sensor data value that is less than the second predetermined threshold;
• and
• taking an action for automatically controlling the vehicle via the processor, including by automatically moving the vehicle in accordance with instructions provided by the processor, based on the confidence level that the fire event is occurring within the parking lot.

• determining, using the preliminary sensor data, whether the vehicle is parking at a parking lot;
• and
• when it is determined that the vehicle is parking in a parking lot, then:
• determining a confidence level as to whether a fire event is occurring in proximity to the parking lot, using the additional sensor data, wherein the confidence level is based on each of the plurality of different modalities, including the tire pressure monitoring sensor data, the ultrasonic sensor data, exterior temperature sensor data, and the interior temperature sensor data, wherein the confidence level is selected from one of the following:
