Technical review of current autonomous braking systems and summary of how AEB works.

Key Findings:

  • No findings per se, however the website offers a great insight into how and why AEB is necessary.

  • AEB is now taken into account when the ratings are calculated for a vehicle during their testing procedure

  • Most AEB systems use radar, (stereo) camera and/or lidar-based technology to identify potential collision partners ahead of the car. This information is combined with what the car knows of its own travel speed and trajectory to determine whether or not a critical situation is developing.

  • If a potential collision is detected, AEB systems generally (though not exclusively) first try to avoid the impact by warning the driver that action is needed. If no action is taken and a collision is still expected, the system will then apply the brakes.

  • AEB systems improve safety in two ways: firstly, they help to avoid accidents by identifying critical situations early and warning the driver; and secondly they reduce the severity of crashes which cannot be avoided by lowering the speed of collision and, in some cases, by preparing the vehicle and restraint systems for impact.

Offers very good insight into AEB, very easy to follow, with most aspects of the system explained well.
