Vehicle extreme temperature safety systems and methods
First Claim
1. A system for preventing excessive thermal stress exposure to any occupants of a vehicle, the system comprising:
- an occupancy sensor;
an occupant body surface temperature sensor configured to detect a body surface temperature of an occupant in the vehicle;
an actuator; and
,a controller configured to receive signals from the occupancy sensor and from the occupant body surface temperature sensor,wherein the controller is configured to determine an occupant body core temperature based on the signals from the occupant body surface temperature sensor when the controller receives an occupant present signal from the occupancy sensor; and
,wherein the controller is configured to activate the actuator when the determined occupant body temperature falls outside a preset temperature range.

Abstract
Safety systems and methods to prevent or mitigate thermal stress conditions in a vehicle. The systems include sensors to detect conditions in and around a vehicle, particularly the temperature inside the vehicle and the condition of occupants. System controllers receive the sensor information, determine the thermal stress status of occupants, and activate appropriate actuators configured to reduce thermal stress in the vehicle. The methods include providing the system, detecting a vehicle occupant surface temperature, using the detected temperature to determine a body core temperature, and activating an actuator if the occupant body core temperature is determined to be out of a preset range.
