Definitions

  • the invention relates to a method and an arrangement for determining a detection area of a pre-crash sensor system.
  • Pre-crash sensing methods are known for determining possible motor vehicle accidents. These methods make use of non-tactile sensors that determine, for example, a relative speed, a time to an expected impact, an impact angle and an expected impact location of an object on a collision course in the vehicle environment.
  • impact probabilities can be determined and objects can be discriminated and object classes assigned using video sensors.
  • Pre-crash detection is a function of the passive safety of the vehicle and is divided into three levels. From a functional point of view, these levels build on each other because they each require a higher level of complexity and sensor capability. Furthermore, these stages follow one another in terms of time until the crash event.
  • the first stage is generally called PRESET ("PREcrash SETting of algorithm thresholds”) and relates to an adaptation of the triggering thresholds of the control algorithms of conventional pyrotechnically ignitable restraint devices.
  • the control of the pyrotechnically ignitable retention center! takes place here only after the start of the crash, since the algorithm also takes the conventional acceleration sensor into account in addition to the pre-crash information.
  • the second stage is generally called PREFIRE (“PREcrash Flring of Reversible Restraints”) and relates to the ignition of reversible restraint devices based on the precrash sensor information even before the start of the crash.
  • the third stage is called PREACT ("Precrash Engagement of ACTive safety"). When it detects an accident probability that exceeds a threshold value to be defined, active safety systems, in particular brakes, engine control, steering, are activated.
  • the detection and determination of the useful data required for the pre-crash sensing is carried out via suitable sensors in a detection area which is dependent on the respective sensor.
  • the respective safety device or the vehicle system of active safety is actuated in each case within a response time or tense time.
  • a detection range can be defined by a predetermined minimum detection distance and a predetermined maximum detection distance, whereby the amount of data is limited.
  • the method according to the invention and the arrangement according to the invention have the particular advantage that it is possible to determine a detection area for a particular driving situation, which ensures the detection of all objects relevant to accidents and yet a suitable limitation of the de - tection range and thus the determined sensor data.
  • the determination of the suitable detection range is advantageously possible with relatively little additional equipment or computing effort.
  • the sub-claims describe preferred further developments. In this case, in particular according to claim 10, a pre-crash detection method is created, in which the method according to the invention is used to determine the detection area.
  • a maximum detection distance is now determined from the tensioning time of a safety device or the tensioning times of several safety devices and driving state variables of the vehicle.
  • the maximum detection distance can preferably be the sum of the distance likely to be covered within the tensing time - which can be determined by integrating the dynamic properties, in particular the vehicle speed and the longitudinal vehicle acceleration - and a suitable measuring distance.
  • the measuring distance can be predefined or determined depending on sensor properties or driving state variables. Accordingly, a minimum detection distance can also be determined from the tense time and driving state variables, which, together with the maximum detection distance, defines the detection range.
  • an object detected by the sensor system can be classified and the determined object class - for example passenger cars, trucks, pedestrians, motorcyclists or cyclists - can be taken into account when setting the safety devices.
  • the safety devices to be set can, according to the invention, both in the PRESET stage mentioned at the outset, the triggering thresholds of the control logic for conventional pyrotechnically ignitable restraint devices, and also in of the PREFIRE stage described at the beginning are reversible restraining devices.
  • Such reversible restraint devices can protect both the protection of vehicle occupants, for example as reversible electromotive belt tensioners, electromotive or electromagnetically operated paddings, the knees or feet or neck and head in the event of a crash by actuating suitable adjusting devices, and also serve by passers-by.
  • systems of active safety in particular brakes, engine control, steering, can be activated in the PREACT stage mentioned at the outset in the pre-crash detection method according to the invention when an accident probability that exceeds a threshold value to be defined is detected.
  • a combined sensor concept is advantageously used, which has a long-range sensor device, preferably with a high-frequency or short-wave radar sensor device, a medium-range sensor device, preferably as a stereoscopic video sensor device with a suitable aperture angle, and a short-range sensor device, in particular with a system of several radar sensors at low frequencies or short-wave basis.
  • These sensor devices are combined to form a sensor system, which thus enables a detection range determined to be relevant to be set over a large length range.
  • data on the driving state of the vehicle from vehicle sensors or variables derived therefrom are used.
  • a detection range when cornering can also be determined from, for example, the set steering angle or a determined yaw rate of the vehicle.
  • the determination of the detection range can be made possible both during a stable driving state and during a skidding process, wherein data of a driving dynamics control or an anti-lock braking system can be used during a skidding process.
  • Figure 1 is a plan view of a vehicle with a sensor system according to the invention on a roadway.
  • FIG. 2 shows a side view of the illustration from FIG. 1 with objects on the road;
  • FIG. 3 shows a plan view of a vehicle on a straight and curved track

  • a short-range first sensor device 4 which uses a plurality of radar sensors based on 24 GHz, is provided for a first measuring range 5 over a first distance to 7 with a first opening angle of 140 °.
  • a medium-range second sensor device 6 has a video system, for example a stereoscopic video system, and will be used for a second measuring range with a second distance of approx. 40 m and a second opening angle of approx. 35 °.
  • a long-range third sensor device 8 uses a 77 GHz radar sensor and covers a third measuring range with a third distance of 9 to approximately 150 m and a third opening angle of 8 °.
  • the opening angle is chosen to be small, since this range is only required at higher speeds on routes with a small curve radius, especially motorways.
  • the short-range sensor device 4 detects a first vehicle 12 as an object on the roadway 2 at a distance d of 6 m and the medium-range sensor device 6, not shown in FIG. witness 13 at a distance of 20 m to the vehicle 1.
  • the two detected objects 12, 13 can be classified by the second sensor device 6 in a manner known per se and assigned to the object class "passenger car"
  • the first, second and third sensor devices 4, 6, 8 give first, second and third sensor signals S, s 2 , s 3 to an evaluation device 10 of the vehicle 1.

Abstract

L'invention concerne un procédé permettant de déterminer une zone de détection d'un système de détection de pré-collision de véhicule, selon lequel une distance de détection maximale (dmax) est déterminée en fonction d'au moins : un temps de réponse (tspann) d'un dispositif de sécurité du véhicule et d'une grandeur d'état de marche déterminée (Veigen, aeigen, φeigen) du véhicule. Selon l'invention, il est ainsi possible de déterminer une zone de détection permettant d'obtenir des signaux de détection suffisants pour une détection fiable de pré-collision et limitant néanmoins de manière significative le volume de données. L'invention concerne en outre un système correspondant.
