The airbag module is for a vehicle. The airbag module has an airbag with a vent. The temperature detector configured to detect an ambient temperature of the vehicle. The electronic controller is programmed to control the airbag module between an active venting condition and a non-venting condition based on a detected result detected by the temperature detector. The vent is in an open state in the active venting condition. The vent is in a closed state in the non-venting condition. ## Claims ### Claim 1 A vehicle airbag control system, comprising: an airbag module for a vehicle, the airbag module having an airbag with a vent; a temperature detector configured to detect an ambient temperature of the vehicle; and an electronic controller programmed to control the airbag module between an active venting condition in which the vent is in an open state and a non-venting condition in which the vent is in a closed state based on a detected result detected by the temperature detector. ### Claim 2 (depends on 1) The vehicle airbag control system according to claim 1, wherein the electronic controller controls the airbag module such that the vent is in the open state when the electronic controller determines that the ambient temperature is in a hot zone. ### Claim 3 (depends on 2) The vehicle airbag control system according to claim 2, wherein the hot zone is a temperature zone in which the ambient temperature is 90 degrees Fahrenheit or above. ### Claim 4 (depends on 1) The vehicle airbag control system according to claim 1, wherein the electronic controller controls the airbag module such that the vent is in the closed state when the electronic controller determines that the ambient temperature is in a cold zone. ### Claim 5 (depends on 4) The vehicle airbag control system according to claim 4, wherein the cold zone is a temperature zone in which the ambient temperature is 50 degrees Fahrenheit or below. ### Claim 6 (depends on 2) The vehicle airbag control system according to claim 2, wherein the electronic controller controls the airbag module such that the vent is in the closed state when the electronic controller determines that the ambient temperature is in a cold zone. ### Claim 7 (depends on 3) The vehicle airbag control system according to claim 3, wherein the electronic controller controls the airbag module such that the vent is in the closed state when the electronic controller determines that the ambient temperature is in a cold zone. ### Claim 8 (depends on 7) The vehicle airbag control system according to claim 7, wherein the hot zone is a temperature zone in which the ambient temperature is 50 degrees Fahrenheit or below. ### Claim 9 (depends on 1) The vehicle airbag control system according to claim 1, further comprising an occupant detector configured to detect a presence of an occupant of the vehicle, the electronic controller being programmed to control the airbag module between a deployed condition in which the airbag is inflated and a non-deployed condition in which the airbag is not inflated based on a detected result of the occupant detector. ### Claim 10 (depends on 9) The vehicle airbag control system according to claim 9, further comprising a seatbelt detector configured to detect whether the occupant is wearing a seatbelt, the electronic controller being programmed to control the airbag module between the active venting condition and the non-venting condition based on a detected result of the seatbelt detector. ### Claim 11 (depends on 6) The vehicle airbag control system according to claim 6, further comprising a seatbelt detector configured to detect whether the occupant is wearing a seatbelt, the electronic controller being programmed to control the airbag module between the active venting condition and the non-venting condition based on a detected result of the seatbelt detector. ### Claim 12 (depends on 11) The vehicle airbag control system according to claim 11, wherein the electronic controller controls the airbag module between the active venting condition and the non-venting condition when the electronic controller determines that the ambient temperature is in a nominal zone that is between the hot zone and the cold zone. ### Claim 13 (depends on 12) The vehicle airbag control system according to claim 12, wherein the electronic controller controls the airbag module such that the vent is in the open state when the electronic controller determines that the occupant is wearing the seatbelt when the ambient temperature is in the nominal zone. ### Claim 14 (depends on 13) The vehicle airbag control system according to claim 13, wherein the electronic controller controls the airbag module such that the vent is in the closed state when the electronic controller determines that the occupant is not wearing the seatbelt when the ambient temperature is in the nominal zone. ### Claim 15 (depends on 12) The vehicle airbag control system according to claim 12, wherein the ambient zone is centered at seventy degrees Fahrenheit. ### Claim 16 A vehicle airbag control system, comprising: an airbag module for a vehicle, the airbag module having an airbag with a vent; a temperature detector configured to detect an ambient temperature of the vehicle; and an electronic controller programmed to control determine whether the ambient temperature is in an ambient temperature zone based on the detected result of the temperature detector, the ambient temperature zone including a hot zone, a cold zone and a nominal zone, the electronic controller being further programmed to control the airbag module between an active venting condition in which the vent is in an open state and a non-venting condition in which the vent is in a closed state based on the temperature zone determined by the electronic controller. ### Claim 17 (depends on 16) The vehicle airbag control system according to claim 16, wherein the electronic controller controls the airbag module such that the vent is in the open state when the electronic controller determines that the temperature zone is in the hot zone. ### Claim 18 (depends on 17) The vehicle airbag control system according to claim 17, wherein the electronic controller controls the airbag module such that the vent is in the closed state when the electronic controller determines that the ambient temperature zone is in the cold zone.
