Abstract
A method for autonomous emergency braking of an ego vehicle includes capturing driving-dynamics variables of the ego vehicle, capturing distance measurement signals, determining a longitudinal distance of the ego vehicle from an object in front, detecting an emergency braking situation based on the driving-dynamics variables and the distance measurement signals. The method further includes advanced determining or projecting, in response to the detecting the emergency braking situation, of first, second, and third starting points for initiation of a warning phase, a subsequent partial braking phase, and an emergency braking brake pressure. The advanced determining or projecting of the first, second, and/or third starting points includes: setting up a minimum period criterion with at least one minimum period and projecting, in advance in accordance with the longitudinal distance from the object, a criticality function that represents a criticality of the traffic situation.
