Definitions

  • the invention relates to an ultrasonic sensor system and method for detecting objects in the environment of a vehicle.
  • Obstacles for example, are used in motor vehicles to assist the driver in maneuvering.
  • the driver is warned acoustically or optically, especially when approaching the obstacles.
  • Ultrasonic sensors can use ultrasound to detect the presence of objects or obstacles within a limited detection area or range and also measure the distance to the objects.
  • a method for the vehicle data dependent distance measurement is known from DE 196 45 339 Al. Next, a distance measuring device in DE 102 61 018 Al is described.
  • the principle of the pulse-echo method is used.
  • the transmission and detection range of the individual ultrasonic sensor is determined by its directional characteristic. This has a vertical opening angle, which usually depends on the sensor geometry and on the control of the ultrasonic sensor, for example the transmission frequency.
  • an ultrasonic sensor can be installed on a vehicle such that its directional characteristic has a certain angle of attack with respect to the vehicle horizontal plane (vertical angle of attack). This can be positive, ie directed upwards, or negative, that is, downwards in the direction of
  • the sensitivity of ultrasonic sensor systems is thus influenced by the shoring on the vehicle. Decisive for this is the height of the applied threshold for the detection of reflected signals, because this is usually adjusted so that ground reflections are hidden. This applies to both fixed and adaptive thresholds. This requirement alone would lead to a sensor design with a very small opening angle or to high angles of attack of the sensor outer surface and the directional characteristic upwards. However, a further requirement in ultrasound sensor systems is also to provide low objects potentially damaging the vehicle, such as e.g. high curbs to detect. Therefore, the ultrasonic sensors must be installed so that a significant proportion of the sound emission, so the directional characteristic, is also directed to the ground.
  • the vertical opening angle of the sound radiation or directional characteristic is e.g. approx. ⁇ 30 ° and the installation of the ultrasonic sensors is to be carried out in such a way that low installation heights of, for example, less than 50 cm with upward angles of attack, ie positive angles of attack and relatively high installation heights of, for example, more than 50 cm with angles of attack directed towards the ground, ie negative angles of attack, be installed.
  • a resulting installation guideline is shown in FIG.
  • DE 10 2009 046 338 A1 further describes a method in which a transmission signal is transmitted by a plurality of ultrasonic sensors, a reception signal generated by reflection of the transmission signal on an object is received by at least one further ultrasonic sensor and the respective reception signal is evaluated in Dependency of a provided sensitivity characteristic for the reception.
  • the sensitivity characteristic is provided as a function of at least one property of the transmitting ultrasonic sensor. It is shown to provide superimposed ultrasonic sensors for detecting obstacles in the region of a bumper, wherein the different ultrasonic sensors can each have different angles of incidence and geometries.
  • arranged object can be estimated.
  • the invention is based on the idea in the area of a bumper
  • Obstacles can be detected particularly well and safely.

  • the core of the invention is therefore the use of additional
  • Ultrasonic sensors which are installed in a level below the usual installation level. This lower level of ultrasonic sensors (second group) Its purpose is to detect low objects. According to the invention
  • the increase in the sensitivity of the first group can be made possible, for example, either by installing the ultrasonic sensors with vertical angles of attack and / or installation heights well above the installation guidelines.
  • the respective directional characteristics of the ultrasonic sensors of the first group have a positive vertical angle of attack, in particular between 0 ° and 15 °, relative to the horizontal plane, ie they are tilted upwards. Due to this alignment, the sensors of the first group detect less ground echoes, whereby the threshold for the detection of the echo signals does not have to be adapted to the fading of ground echoes. Thus, a (fixed or adaptive) threshold can be used for the detection of echo signals, which makes it possible to detect even weakly reflecting objects, such as pedestrians. Accordingly, the sensitivity of the ultrasonic sensors with respect to the detection of objects increases.
  • the respective directional characteristics of the ultrasonic sensors of the second group are preferably aligned horizontally or have a negative vertical angle of attack relative to the horizontal plane.

  • ultrasonic sensors with smaller vertical opening angles can be used in comparison to the ultrasonic sensors of the second group.
  • the lower vertical Aperture angle results in fewer ground echoes being received by the ultrasound sensors of the first group and, correspondingly, a detection threshold that allows detection of low-reflectivity objects or more distant objects.
  • a smaller vertical opening angle can be realized in various ways within the scope of the invention.
  • the ultrasonic sensors are designed such that they have in a known manner a diaphragm pot with a vibratory membrane and a circumferential wall around the membrane, wherein on a inside of the membrane, a piezoelectric transducer is arranged.
  • the ultrasound sensors of the first group can now have a smaller diaphragm diameter than the ultrasound sensors of the second group, resulting in a comparatively lower vertical aperture angle of the directional characteristic for the ultrasound sensors of the first group.
  • the ultrasonic sensors of the first group may have a higher membrane rigidity. This leads to a comparatively increased resonance frequency of the diaphragm pot. A higher resonance frequency results in a lower vertical opening angle of the directional characteristic and thus leads to an increased sensitivity.
  • the ultrasonic sensors of the first group are preferably operated at a higher transmission frequency than the ultrasonic sensors of the second group.
  • a higher transmission frequency results in a lower compared vertical
  • Opening angle of the directional characteristic When using different transmission frequencies for the two groups, preferably the same
  • Sensor structure and the same sensor geometry, in particular the same membrane diameter can be used for the respective ultrasonic sensors of the two groups.
  • the transmission frequency for the first group should only be increased so far that the ultrasonic sensors of the second group still have sufficient sensitivity in this frequency range, preferably> 50% based on the sensitivity of the ultrasonic sensors of the first group.
  • a variation of the vertical opening angle can also be achieved by incorporating an ultrasonic sensor in a funnel-shaped holder, wherein the effective directional characteristic achieved with respect to the object detection is influenced by the geometry of the funnel.
