Automatic emergency braking method and arrangement
First Claim
1. A method for emergency braking of a vehicle having a detection system which detects obstacles located in or near the direction of motion of the vehicle and sensors which provide characteristic parameters of the condition of the vehicle and an evaluating unit which determines target quantities for controlling the motion of the vehicle from data concerning the obstacles and the parameters of vehicle condition and an automatic emergency braking system comprising determining in the evaluation unit a situation in which an impending collision of the vehicle with an obstacle can no longer be avoided by any steering and/or braking action of the vehicle and triggering the automatic emergency braking system to produce rapid deceleration of the vehicle only after the evaluating unit has determined that an impending collision of the vehicle with an obstacle can no longer be avoided by any steering and/or braking action of the vehicle to minimize the effect of the collision, wherein the automatic emergency braking system is not triggered by a situation in which a collision is possible but still avoidable as determined by the evaluation unit.

Abstract
A method and arrangement for emergency braking of a vehicle includes a detection system on the vehicle which detects obstacles located in or near the direction of motion of the vehicle and generates corresponding data, sensors on the vehicle which generate data representing characteristic parameters of the condition of the vehicle, and an evaluating unit which determines, from the data on the obstacles and the parameters of the condition of the vehicle, target values for controlling the motion of the vehicle and, only upon determining that an impending collision of the vehicle with an obstacle is no longer avoidable by any action on the vehicle by steering or braking, triggers an automatic emergency braking for rapid deceleration of the vehicle.
