Automatic passenger airbag switch
Techniques described herein include a system and method for switching an airbag on or off based on determining that an object situated in a vehicle seat meets one or more conditions. In some embodiments, the vehicle seat may be fitted with a weight sensor configured to detect an object situated in the vehicle seat. The system may include a camera device configured to capture image information associated with the object situated in the vehicle seat. The image information may be processed to determine if the object is a person meeting one or more threshold conditions for activating the airbag. Upon processing the image information, the airbag may be provided with instructions to either activate or deactivate.
1. An airbag deployment apparatus, comprising:
an airbag deployment device configured to deploy an airbag in a vehicle in a collision event;
a sensor device configured to detect an object situated in a vehicle seat;
a pyroelectric sensor positioned on a ceiling of the vehicle above the vehicle seat, wherein the pyroelectric sensor is configured to detect height information related to the object situated in the vehicle seat by determining a distance between the pyroelectric sensor and a top of the object via infrared rays emitted by the object; and
a processor device configured to activate the airbag deployment device upon determining, from the pyroelectric sensor, that the object situated in the vehicle seat has a height above a height threshold.
2. The airbag deployment apparatus of claim 1 , wherein the sensor device is a pressure sensor.
3. A method of activating and deactivating an airbag deployment device in a vehicle, comprising:
detecting an object situated in a vehicle seat;
activating a pyroelectric sensor positioned on a ceiling of the vehicle above the vehicle seat, wherein the pyroelectric sensor is configured to detect height information related to the object situated in the vehicle seat by determining a distance between the pyroelectric sensor and a top of the object via infrared rays emitted by the object;
receiving information from the pyroelectric sensor related to whether the object situated in the vehicle seat has a height above a height threshold; and
providing activation instructions to the airbag deployment device, based at least in part on whether the object in the vehicle seat has a height above the height threshold.
4. The method of claim 3 , wherein providing activation instructions to the airbag deployment device comprises at least one of:
upon determining that the object situated in the vehicle seat has the height above the height threshold, activating the airbag deployment device; and
upon determining that the object situated in the vehicle seat does not have the height above the height threshold, deactivating the airbag deployment device.
5. The method of claim 3 , wherein the object is detected as being situated in the vehicle seat using a weight sensor.
6. A vehicle airbag system, comprising:
a vehicle seat equipped with one or more weight sensors;
an airbag deployment device configured to deploy an airbag to the vehicle seat;
a pyroelectric sensor positioned on a ceiling of the vehicle above the vehicle seat, wherein the pyroelectric sensor is configured to detect height information related to the object situated in the vehicle seat by determining a distance between the pyroelectric sensor and a top of the object via infrared rays emitted by the object;
a processor device; and
a memory including instructions that, when executed by the processor device, cause the vehicle airbag system to, at least:
receive information from the pyroelectric sensor related to whether the object situated in the vehicle seat has a height above a height threshold;
provide activation instructions to the airbag deployment device, based at least in part on whether the object in the vehicle seat has the height above the height threshold.
7. The vehicle airbag system of claim 6 , wherein the instructions further cause the vehicle airbag system to access a user profile related to the person situated in the vehicle seat, the user profile including data related to a person situated in the vehicle seat.
8. The vehicle airbag system of claim 7 , wherein the user profile is associated with one or more configuration settings, wherein the instructions to the airbag deployment device are provided based at least in part on the one or more configuration settings.
9. The vehicle airbag system of claim 8 , wherein the one or more configuration settings includes data related to at least one of an age or a medical condition.
