Collision warning

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.

In contrast to the collision warning, with Active Cruise Control (ACC = Radar), a camera-based technology is applied. Beyond a speed threshold of 15 km/h, the collision warning can issue warnings to rear views of vehicles.

The collision warning has the following subfunctions:

Initial warning
Warning, e.g. for signs of collision risk or for very small distances to a vehicle ahead.

Warning through red vehicle symbol in the instrument cluster, alternative Head-Up Display.
- Static prewarning for small distance
- Dynamic prewarning for approaching
Acute warning
Warning for immediate risk of collision, if the vehicle approaches another object with relatively high differential speed. Flashing red vehicle symbol in the instrument cluster, alternative Head-Up Display and acoustic warning signal
Pre-filling of the brake
Adaptation of the thresholds for the Dynamic Brake Control

A Check Control message is also issued.

The time of the warning can be dependent on different values. For example:

Classification of the current driving situation
Possibly wet roadway
Estimation of the attention of the driver via pedal movements and steering wheel movements
