System Outline

* To reduce the steering force requires by the driver, an appropriate amount of assist current is calculated from the torque sensor signal and the vehicle speed signal and then output to the motor.

* When an abnormality is found in the system, the power relay and motor relay (Built in the ECU) are shut off to stop the assistance and the warning lamp (P/S) illuminates in the meter.

* The system reaches an ignition judgment to deploy the following devices based on the signals received from the front airbag sensor and deceleration sensor.

• Driver Airbag
• Front Passenger Airbag
• Seat Belt Pretensioner

* The system reaches an ignition judgment to deploy the following devices based on the signals received from the side airbag sensors.

• Side Airbags
• Curtain Shield Airbags

* A dual-stage SRS airbag system has been used for the driver and front passenger airbags. This system optimizes the airbag inflation by judging the extent of impact, seat position (driver seat), whether or not the seat belt is fastened (driver seat) and information from the front passenger occupant classification system.

* The front passenger occupant classification system judges whether the front passenger seat is occupied by an adult or child (with child seat) or is unoccupied, according to the load applied to the front passenger seat and whether the seat belt is buckled.

Based on the results, it restricts the deployment of the front passenger airbag, front passenger side airbag, and front passenger seat belt pretensioner. In addition, the system informs the driver of the result of the judgment through the use of the AIRBAG ON/OFF indicator lights.

* A Roll Sensing Curtain Shield Airbag system has been adopted in order to deploy the curtain shield airbags and the pretensioners, in the event that the vehicle rolls over.
