Collision avoidance features
ALKS deals with some cases of collision avoidance.
ALKS defines some concepts:
Imminent collision risk describes a situation or an event which leads to a collision of the vehicle with another road user or an obstacle which cannot be avoided by a braking demand with lower than 5 m/s
— Uniform provisions concerning the approval of vehicles about automated lane-keeping systems
Emergency Manoeuvre (EM) is a maneuver performed by the system in case of an event in which the vehicle is at imminent collision risk and has the purpose of avoiding or mitigating a collision.
— Uniform provisions concerning the approval of vehicles about automated lane-keeping systems
The activated system shall not cause any collisions that are reasonably foreseeable and preventable. If a collision can be safely avoided without causing another one, it shall be avoided. When the vehicle is involved in a detectable collision, the vehicle shall be brought to a standstill.
— Uniform provisions concerning the approval of vehicles concerning automated lane-keeping systems
The activated system shall detect the distance to the next vehicle in front as defined in paragraph 7.1.1. and shall adapt the vehicle speed to avoid collision.
— Uniform provisions concerning the approval of vehicles about automated lane-keeping systems
The activated system shall be able to bring the vehicle to a complete stop behind a stationary vehicle, a stationary road user, or a blocked lane of travel to avoid a collision. This shall be ensured up to the maximum operational speed of the system.
