Definitions

  • the invention relates to an improved emergency brake assistant for a vehicle, which takes into account the rear area in the definition of emergency braking parameters. Even during the emergency braking process, the rear area is monitored and the emergency brake parameters adjusted if necessary.
  • Environmental monitoring systems must therefore be reliable and the emergency braking play out in an optimal framework in order to prevent a collision with an object lying in front of the vehicle on the one hand and with a following vehicle on the other hand.
  • the object of the present invention is to improve an emergency brake assistant and a method for operating an emergency brake assistant.
  • the method for automatic emergency braking of a vehicle comprises the following steps, an object detection in the area in front of and behind the vehicle; and setting at least one
  • Emergency braking parameters as a function of at least one detected object in the Area in front of the vehicle; wherein at least one emergency braking parameter is modified if there is no object in the area behind the vehicle,
  • an emergency braking with the optimum parameters can thus take place, since no consideration has to be given to the traffic at the rear.
  • the emergency brake parameters may preferably be at least one permissible one
  • Speed range within which the emergency brake assist is active or a delay request; or a speed reduction; or time of emergency braking.
  • Delay request or deceleration can be set to an optimum value to avoid collision with the object before
  • an optimal value could be the maximum possible
  • Optimum values for the speed range are, among others, the values for standardized speed limits in and out of town, ie the ranges 30 - 50, 70 - 100 and 130 km / h.
  • emergency braking can take place in any speed range, since there is no danger from a rear-end collision due to the lack of objects in the rear area.
  • the emergency braking parameter can be modified as follows: the permissible speed range is increased or the
  • Deceleration request is increased or the deceleration is increased or the timing of the emergency deceleration is advanced.
  • the time of emergency braking can be advanced to have more time to decelerate the vehicle.
  • the increase of at least one of the emergency braking parameters can be maintained until an object, in particular a driving
  • such a recognized object in the rear area before or during emergency braking can be considered and the initiation or further implementation of the emergency braking can be changing
  • Traffic situations are adjusted.
  • the increase in the emergency braking parameters can be withdrawn and the standard parameters are used.
  • the object detection in the area behind the vehicle can determine a relative speed or a distance of the detected objects.
  • the distance and the relative speed are advantageousously, the distance and the relative speed
  • Notbremsparameter done dynamically with the relative speed or the distance of the detected object.
  • the adaptation of the emergency brake parameters during the emergency braking can be carried out continuously and so the emergency brake parameters are adapted to the emergency braking behavior of the own vehicle or to the behavior of the subsequent object.
  • an evasive maneuver can be performed when a collision with the detected object in the area in front of the vehicle and the detected object in the area behind the vehicle, in particular a moving following vehicle, by emergency braking is no longer preventable.
  • an evasive action can be initiated.
  • an emergency brake assistant for a vehicle comprises
  • Object recognition unit for the area in front of and behind the vehicle; and a control unit for carrying out the preferred method, wherein the control unit comprises an electronic memory on which a method according to one of the preceding claims is stored.
  • the middle vehicle 3 is equipped with an object detection unit 5, 7 for the area before 13 and behind 15 the vehicle 3.
  • the respective object detection unit 5 for the area before 13 and behind 15 the vehicle 3.
  • Object detection unit detects objects before 13 and behind 15 the vehicle 3, if objects 9, 1 1, or vehicles are in this area.
  • FIG. 2 shows a flowchart for the operation 21 of an emergency brake assistant.
  • the object detection unit 23 monitors the rear area of the vehicle and searches for objects in this area 25. If objects 31 are detected, the set default parameters 27 are used as emergency braking parameters for emergency braking. If, on the other hand, no objects are detected in the rear region 25, an emergency braking which may be initiated is carried out with optimum optimum parameters 29, which are higher than the standard parameters, as emergency brake parameters.
  • the method shown in Fig. 2 for the operation 21 of the emergency brake assist is also performed during an already held emergency braking. If, after the beginning of the emergency braking operation, the object detection unit 23 recognizes an object in the rear area 25 31, the emergency braking is continued with the standard parameters 27. The increased optimum parameters 29 are therefore no longer used.
  • intermediate parameters can also be used which lie between the optimum parameters 29 and the standard parameters 27.
  • FIG. 3 shows a diagram for the course of an emergency braking parameter 41.
  • the object detection system detects an object in the rear of the vehicle and reduces the allowed
  • Vehicles monitor the respective traffic space and determine the
  • the control unit 65 then adjusts the emergency braking parameters to the detected objects and controls the braking system 67 of the vehicle accordingly.
