Automatic emergency steering

How this technology works

Automatic emergency steering uses sensors to detect potential collisions with a vehicle ahead and automatically steers the vehicle to avoid a collision or make it less severe. Some systems may also detect pedestrians or other objects.

Some systems can help steer when the drivers steering isn't enough to avoid a collision. Others can help steer even if a driver doesn't move the steering wheel to avoid a collision.

Operation

Automatic emergency steering is an active safety system that the driver doesn't have to turn on. Drivers can take over the automatic steering by turning the steering wheel. Systems can be switched off at times, but they will be automatically activated again the next time the vehicle starts.

Other names for this technology

  • Autonomous Emergency Steering System
  • Emergency steering control
  • Emergency steering takeover systems
  • Evasive Steering Assist
A car’s front sensor detects stopped vehicle. Its side sensors identify an opening in the adjacent lane and the car moves over to avoid a collision.

Things for drivers to keep in mind

  • Automatic emergency steering systems are designed to help you avoid collisions
    • They can't replace your attention and judgment
    • You should always keep a safe speed and following distance from the traffic ahead, and stay focused on the road
  • The system may not work in all traffic, weather, and road conditions, like:
    • in heavy rain
    • in snow
    • in dense fog
    • in strong sunlight
    • at night on curved roads
  • The system shouldn't activate in normal driving situations, only in cases when a collision could occur 
  • Don't depend on this technology to avoid collisions. It is only for situations where you can't avoid a collision
  • Some automatic emergency steering systems may be able to detect vehicles, pedestrians, cyclists or large animals
  • These systems may be limited to city or highway speeds
    • Make sure you know what the operating speed range is for your vehicle
  • Drivers are encouraged to read the owner's manual to become familiar with this system, including its capabilities and limitations
