Side impact, function - GF91.60-P-2005QMC
MODEL 209.4 as of 1.6.04 with CODE (494a) USA version
Progress of sidebag deployment, shown on model 171.4
The times that are specified are merely intended to indicate the short duration of the sidebag inflation and deflation process.
Side impact collision
If a side impact is detected by the left sidebag and windowbag sensor (A53/1) or the right sidebag and windowbag sensor (A54/1), the lateral body acceleration data are transmitted to the restraint systems control unit (N2/7). The restraint systems control unit (N2/7) checks the plausibility of the data. If plausible, the following squibs are ignited in the event of a side collision from the left:
- Front left sidebag squib (R12/20)
- left rear sidebag squib (R12/11)
In the event of side collision from right:
- Right front sidebag squib (R12/21)
- right rear sidebag squib (R12/12)
The WSS (Weight Sensing System) control unit (N2/13) detects the occupancy of the front passenger seat with the aid of the pressure sensor (B48/4). In order to determine whether a child seat is present, the belt tension sensor (B48/3) is also read in by the WSS (Weight Sensing System) control unit (N2/13) and the relevant message sent to the restraint systems control unit (N2/7) via the Controller Area Network Bus class B (interior) (CAN-B). If the front passenger seat is unoccupied or a child seat has been installed, the right front sidebag squib (R12/21) is not deployed.
If there is a fault in the seat occupied recognition, the right front sidebag squib (R12/21) is deployed for safety reasons.
