Abstract

A vehicle system includes temperature sensors positioned in the vehicle and a control module in communication with the temperature sensors. The temperature sensors are configured to measure surface temperatures of objects in the vehicle. The control module is configured to receive the measured surface temperatures from the temperature sensors, determine whether any of the measured surface temperatures is greater than a defined threshold, and in response to any of the measured surface temperatures being greater than the defined threshold, transmit an alert signal to a user communication device indicative of the objects in the vehicle having the measured surface temperatures greater than the defined threshold.

First claim

What is claimed is:

1 . A vehicle system for selectively controlling airflow in a vehicle, the vehicle system comprising:
a plurality of temperature sensors positioned in the vehicle, the plurality of temperature sensors configured to measure surface temperatures of a first set of objects in the vehicle; and a control module in communication with the plurality of temperature sensors, the control module configured to:
receive the measured surface temperatures from the plurality of temperature sensors;
determine whether any of the measured surface temperatures is greater than a defined threshold;
receive vehicle data associated with the vehicle and environmental data associated with an environment around the vehicle, the vehicle data including one or more of a vehicle heading, a pitch of the vehicle, a yaw of the vehicle, and a latitude and longitude of the vehicle, and the environmental data including at least forecasted weather data;
estimate a surface temperature of a second object in the vehicle based on the received vehicle data and the environmental data;
determine whether the estimated surface temperature of the second object is greater than the defined threshold; and
in response to at least one of the measured surface temperatures and the estimated surface temperature being greater than the defined threshold, transmit an alert signal to a user communication device indicative of each of the first set of objects and the second object in the vehicle having the measured surface temperatures or estimated surface temperature greater than the defined threshold.

2 . The vehicle system of claim 1 , wherein the control module is configured to, in response to one of the measured surface temperatures being greater than the defined threshold, identify at least one zone in the vehicle that directs airflow to the object having the measured surface temperature that is greater than the defined threshold and selectively control a climate control module to cool the zone in the vehicle.

3 . The vehicle system of claim 2 , wherein the control module is configured to selectively control the climate control module to cool the zone in the vehicle until the measured surface temperature is less than the defined threshold.

4 . The vehicle system of claim 1 , wherein the control module is configured to:
determine whether one of the objects in the vehicle having the measured surface temperatures greater than the defined threshold is touched for a defined period of time; and in response to determining that one of the objects is touched for the defined period of time, transmit an emergency signal to the user communication device.

5 . The vehicle system of claim 1 , wherein the plurality of temperature sensors includes at least one infrared temperature sensor.

6 . The vehicle system of claim 1 , wherein at least one temperature sensor of the plurality of temperature sensors is configured to measure a surface temperature of a seat, a center console, a steering wheel, an arm rest, or a child car seat.

7 . The vehicle system of claim 1 , wherein:
at least one temperature sensor of the plurality of temperature sensors is an infrared temperature sensor configured to measure a surface temperature of a seat, a center console, a steering wheel, an arm rest, or a child car seat; and the control module is configured to, in response to one of the measured surface temperatures being greater than the defined threshold, identify at least one zone in the vehicle that directs airflow to the object having the measured surface temperature that is greater than the defined threshold, and selectively control a climate control module to cool the zone in the vehicle until the measured surface temperature is less than the defined threshold.

8 . A method for selectively controlling airflow in a vehicle, the method comprising:
receiving, from a plurality of temperature sensors, measured surface temperatures of first set of objects in the vehicle; determining whether any of the measured surface temperatures is greater than a defined threshold; receiving vehicle data associated with the vehicle and environmental data associated with an environment around the vehicle, the vehicle data including one or more of a vehicle heading, a pitch of the vehicle, a yaw of the vehicle, and a latitude and longitude of the vehicle, and the environmental data including at least forecasted weather data; estimating a surface temperature of a second object in the vehicle based on the received vehicle data and the environmental data; determining whether the estimated surface temperature of the second object is greater than the defined threshold; and in response to at least one of the measured surface temperatures and the estimated surface temperature being greater than the defined threshold, transmitting an alert signal to a user communication device indicative of each of the first set of objects and the second object in the vehicle having the measured surface temperatures or estimated surface temperature greater than the defined threshold.

9 . The method of claim 8 , further comprising identifying at least one zone in the vehicle that directs airflow to at least one of the objects having with the measured surface temperature that is greater than the defined threshold and selectively controlling a climate control module to cool the zone in the vehicle.

10 . The method of claim 9 , wherein selectively controlling the climate control module to cool the zone in the vehicle includes selectively controlling the climate control module to cool the zone in the vehicle until the measured surface temperature is less than the defined threshold.

11 . The method of claim 10 , further comprising:
determining whether one of the objects in the vehicle having the measured surface temperatures greater than the defined threshold is touched for a defined period of time; and in response to determining that one of the objects is touched for the defined period of time, transmitting an emergency signal to the user communication device.

12 . The method of claim 8 , wherein the plurality of temperature sensors includes at least one infrared temperature sensor.

13 . The method of claim 12 , wherein receiving surface temperatures of objects in the vehicle includes receiving surface temperatures of a seat, a center console, a steering wheel, an arm rest, and/or a child car seat.

14 . A method for warning users, the method comprising:
receiving vehicle data associated with the vehicle and environmental data associated with an environment around the vehicle, the vehicle data including one or more of a vehicle heading, a pitch of the vehicle, a yaw of the vehicle, and a latitude and longitude of the vehicle, and the environmental data including at least forecasted weather data; estimating a surface temperature of an object of the vehicle based on the received vehicle data and the environmental data; determining whether the estimated surface temperature of the object is greater than a defined threshold; and in response to determining the estimated surface temperature of the object is greater than the defined threshold, transmitting an alert signal to a user communication device to notify a user of the object having the estimated surface temperature greater than the defined threshold.

15 . The method of claim 14 , wherein:
the method further comprises generating one or more recommendations to decrease the estimated surface temperature of the object in response to determining the estimated surface temperature of the object is greater than the defined threshold; and tran
