Hyundai Ioniq (AE): Restraint / General information

The supplemental restraint system (SRS) is designed to supplement the seat belt to help reduce the risk or severity of injury to the driver and passenger by activating and deploying the driver, passenger, side airbag and belt pretensioner in certain frontal or side collisions.

The SRS (Airbag) consists of ; a driver side airbag module located in the center of the steering wheel, which contains the folded cushion and an inflator unit ; a passenger side airbag module located in the passenger side crash pad contains the folded cushion assembled with inflator unit ; side airbag modules located in the front seat contain the folded cushion and an inflator unit ; curtain airbag modules located inside of the headliner which contains folded cushions and inflator units. The impact sensing function of the SRSCM is carried out by electronic accelerometer that continuously measure the vehicle’s acceleration and delivers a corresponding signal through amplifying and filtering circuitry to the microprocessor.

SRSCM (SRS Control Module)

SRSCM will detect front impact with front impact sensors and internal acceleration sensors inside of SRSCM. For side impact, SRSCM will detect the side impact with 4 side impact sensors, 2 conventional acceleration sensors in Center pillar inner locations and 2 pressure sensing sensors in side of front door module, and internal acceleration sensor inside of SRSCM.

SRSCM is designed to issue corresponding airbag module(s) deployment(s) using above described sensor inputs.
