Definitions

  • the invention relates to an automatic emergency braking system in a vehicle and to a method for operating the vehicle
  • the distance is shortened on the basis of information of the preceding vehicle.
  • the object of the present invention is to improve the acceptance of an emergency braking system.
  • Environment detection system includes the following steps, determining a distance to a preceding vehicle by the surroundings detection system and initiating the emergency braking operation depending on the distance and a status value, the status value having a first state for initiating the emergency braking operation and a second state for not initiating the emergency braking operation ,
  • a collapse of a vehicle from the secondary lane are made possible without an emergency braking process is initiated although the einscherende vehicle falls below the safety distance and actually an emergency braking should take place.
  • the status value would only have the second state
  • An attentive driver can prevent the initiation of the emergency braking process by setting the status value, because he considers emergency braking in spite of falling below the safety distance unnecessary on the basis of his situation assessment.
  • the status value can be influenced by a lighting system of the vehicle.
  • the status value can be replaced by a
  • a driver can indicate to another driver or vehicle the shearing by pressing the flasher and at the same time the own emergency braking system
  • the Status value can be converted from a second state after a period of time back to the first state.
  • the shearing vehicle has the safety distance restored within a specified period of time, so that the emergency braking process should be initiated again alone depending on the distance.
  • the first state can therefore also be regarded as a standard state for the status value.
  • the light horn switch can convert the status value in the second state.
  • the emergency brake operation can only be deactivated by the light horn switch.

Abstract

L'invention concerne un procédé pour commander un processus de freinage d'urgence d'un véhicule au moyen d'un système de détection d'environnement, ce procédé comprenant les étapes suivantes : détermination de la distance entre le véhicule et un véhicule précédent au moyen du système de détection d'environnement et déclenchement du processus de freinage d'urgence en fonction de cette distance et d'une valeur d'état, l'invention étant caractérisée en ce que la valeur d'état présente un premier état pour le déclenchement du processus de freinage d'urgence et un deuxième état pour le non-déclenchement du processus de freinage d'urgence.
