BMW 5 Series: Introduction
The hidden protector
The passive safety system of the G30 is based on the objectives and characteristics of current BMW models. The passive safety system fulfils all legislative requirements worldwide.
The restraint systems ensure that the risk of injury is reduced.
The 5th generation Advanced Crash Safety Module (ACSM) is used as the central airbag control unit for the passive safety system in the G30. With the passive safety system of the G30, the central sensor system is integrated in the ACSM control unit, which is installed in the center of vehicle.
The ACSM of the G30 is a bus user in the FlexRay. This allows the sensor data of the central sensor system to be transferred to the Dynamic Stability Control (DSC).
The following bus overview shows an overview of the G30 vehicle electrical system structure and the incorporation of the Advanced Crash Safety Module (ACSM) in the FlexRay.

24 V Electronic Power Steering
The greater weight of the engines in the G30 on vehicles with 8-cylinder
engines results in a higher
front axle load. This has the effect that the required power of the steering
assist increases. Due to
these high currents, it is necessary to increase the voltage supply of the EPS
to 24 V.
