BMW 3: Evasion assistance

Concept

The system supports the driver in making evasive maneuvers in certain situations, such as when obstacles or persons suddenly appear.

General information

The system issues a warning and intervenes to support the driver if a lateral evasive maneuver is possible. Sensors monitor and detect the clearance around the vehicle. If the system identifies space alongside the vehicle, it supports an evasive maneuver begun by the driver by safely providing targeted steering support.

Safety information

Warning The system cannot serve as a substitute for the driver's personal judgment in assessing visibility and traffic situation. There is a risk of accident.

Adjust driving style to traffic conditions. Watch traffic closely and actively intervene where appropriate.

Warning Indicators and warnings cannot serve as a substitute for the driver's personal judgment. Due to its limits, the system may not issue warnings or reactions, or these may be issued late or in a manner that is not consistent with their normal use. There is a risk of accident. Adjust driving style to traffic conditions. Watch traffic closely and actively intervene where appropriate.

Overview

Radar sensors

The radar sensors are located in the bumpers.

Safety

Front center bumper.

Safety

Front side bumper.

Safety

Rear bumper.

Always keep the bumper in the area of the radar sensors clean and unobstructed.

Camera

Safety

The camera is installed near the interior mirror.

Keep the windshield in front of the interior mirror clean and clear.

Functional requirements

  • Pedestrian warning with braking function is switched on.
  • Front collision mitigation is switched on.
  • Sensors detect sufficient clearance around the vehicle.

Switching on/off

The system is automatically active after every driving off.

Warning with evasion support

Display in the instrument cluster

A warning symbol appears in the instrument cluster and in the Head-up Display if a collision with a detected vehicle is imminent.

Symbol lights up red: prewarning.

Brake and increase distance.

Symbol flashes red and an acoustic signal sounds: acute warning for obstacles.

Brake and make an evasive maneuver, if necessary.

Symbol flashes red and an acoustic signal sounds: acute warning for pedestrians.

Brake and make an evasive maneuver, if necessary.

Acute warning with evasion support

An acute warning is displayed when there is an imminent danger of collision due to the vehicle approaching another object at a high speed.

Intervene in the case of an acute warning. The system is designed to provide assistance by taking evasive action when there is a risk of collision.

Acute warnings may be provided even when there has been no prior warning.

System limits

Safety information

Warning The system is designed to operate in certain conditions and circumstances. Due to conditions or other factors, the system may not respond.

There may be a risk of accident or risk of damage to property. Actively intervene as warranted. Refer to the information in this Owner's Manual regarding the scope of the system's operation and limitations.

Detection range

Safety

The system's detection potential is limited.

Only objects that are detected by the system are taken into account.

Thus, a system reaction might not come or might come late.

The following situations may not be detected, for example:

  • Slow moving vehicles when you approach them at high speed.
  • Vehicles that suddenly swerve in front of you, or sharply decelerating vehicles.
  • Vehicles with an unusual rear appearance.
  • Two-wheeled vehicles ahead of you.

Functional limitations

The system may not be fully functional in the following situations:

  • In heavy fog, wet conditions, or snowfall.
  • In tight curves.
  • If the driving stability control systems are limited or deactivated, for instance DSC OFF.
  • If the field of view of the camera or the windshield is dirty or covered in the area of the interior mirror.
  • If the camera has overheated and been temporarily switched off due to excessively high temperatures.
  • Depending on the equipment: if the radar sensors are dirty or covered.
  • After improperly performed work on the vehicle paint in the area of the radar sensors.
  • Up to 10 seconds after the start of the engine via the Start/Stop button.
  • During calibration of the camera immediately after vehicle delivery.
  • If there are constant blinding effects because of oncoming light, for instance from the sun low in the sky.
