BMW 5 Series: Airbag front sensor
Two airbag front sensors are installed in the front area of the engine supports. The measured values are forwarded to the Advanced Crash Safety Module (ACSM) where they are evaluated.
The airbag front sensors on the left and right assist with the identification of a head-on crash.
The sensors deliver additional information to the Advanced Crash Safety Module (ACSM) on the characteristics and severity of the collision. Each sensor contains an acceleration sensor for recording the deceleration, signal processing technology and electronics for data transfer. The measured values are sent in the form of a message to the Advanced Crash Safety Module (ACSM) and are used in the calculation of the algorithm.

Sensors in the ACSM
In the G30, the central sensor system is integrated in the ACSM. The ACSM contains a longitudinal and lateral acceleration sensor, a vertical acceleration sensor and a roll rate sensor (with the Dynamic Damper Control (OE 223)) for the impact detection. The ACSM also includes a longitudinal and lateral acceleration sensor and a yaw sensor for the driving dynamics control.
The sensor data for impact detection are evaluated in the ACSM and help identify side-on, rear-end or head-on crashes and assists with roll-over detection. The sensor data not yet evaluated for the driving dynamics control is sent to the DSC via FlexRay where it is processed.

CIS mat
The capacitive interior sensing mat (CIS mat) is fitted in the front passenger seat. The CIS mat detects whether the front passenger seat is occupied by an adult or a by child in a child seat. The deactivation of the front passenger airbag, the side airbag and the knee airbag on the passenger's side is signalled by the indicator light for front passenger airbag deactivation.

Concept
The AUTO program cools, ventilates or heats
the car's interior automatically.
The air distribution and temperature are controlled
automatically depending on the temperature
in the car's interior and the desired temperature
setting including the selected intensity of the air
flow.

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.
