ACSM: Crash safety module

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

The crash safety module (ACSM) evaluates the signals from the pedestrian protection sensor(s) ("ACSM" stands for "Advanced Crash Safety Module"). If a collision with a pedestrian is registered by the pedestrian protection sensor(s), the crash safety module always triggers all the actuators for pedestrian protection.

Pedestrian protection only triggers within a defined driving speed range. Outside of the defined driving speed range, the function is blocked in the crash safety module.
