AIRBAG SYSTEM SYSTEM DESCRIPTION


  1. GENERAL


    1. Deceleration sensors and pressure sensors used for the airbag system are installed on various parts on the vehicle and calculate the deceleration rate and pressure of each part during a collision.

    2. Depending on the situation, the airbag sensor assembly sends a deployment signal to each airbag squib, pretensioner squib and pop up hood squib based on the information from each sensor.

  2. DEPLOYMENT CONDITION (ITEMS FOR OCCUPANT PROTECTION)


    1. FRONTAL COLLISION

      A01CZVAE02

      1. Frontal collision signals are produced based on the information from the airbag sensor assembly and front airbag sensors.

        Tech Tips

        *1: In case of a frontal collision, the SRS ignition signal may be output after receiving an ON signal from the deceleration sensor built into the airbag sensor assembly even without a signal from the front airbag sensors.

      2. Frontal collision signals are used to deploy the airbags and pretensioners in the illustration.

    2. SIDE COLLISION (Pattern 1)

      A01CZAHE01

      1. Side collision (Pattern 1) signals are produced based on the information from the airbag sensor assembly and side airbag sensor assembly.

      2. Side collision (Pattern 1) signals are used to deploy the airbags and pretensioner in the illustration.

    3. SIDE COLLISION (Pattern 2)

      A01CZTOE07

      1. Side collision (Pattern 2) signals are produced based on the information from the airbag sensor assembly and rear airbag sensor.

      2. Side collision (Pattern 2) signals are used to deploy the airbags in the illustration.

  3. DEPLOYMENT CONDITION (ITEMS FOR PEDESTRIAN PROTECTION)


    1. A pedestrian collision signal is sent from the pedestrian protection sensors to the airbag sensor assembly.

      A01CZ49E01
      *1 Pedestrian Protection Sensor LH/RH
      *2 Airbag Sensor Assembly
      *3 Vehicle Speed Signal, etc.
      *4 Pop Up Hood Squib LH/RH (Pop Up Hood Lifter Assembly LH/RH)

    2. Based on a signal from the pedestrian protection sensors and vehicle speed signal, etc., when the specified conditions are met, the airbag sensor assembly sends an ignition signal to the pop up hood lifters.
