Description

The present invention relates to an ultrasonic sensor for a vehicle for mounting in a recess of a trim panel of the vehicle, comprising a cup-shaped diaphragm housing having an ultrasonic diaphragm formed in a bottom portion thereof, and a decoupling ring annularly surrounding the diaphragm housing at the bottom portion thereof.

Also, the present invention relates to an arrangement comprising a trim part for a vehicle, and at least one above ultrasonic sensor, wherein in the trim part at least one recess is formed, and the at least one ultrasonic sensor is held in the at least one recess.

Furthermore, the present invention relates to a mounting panel for attachment in the region of a recess of a trim part of a vehicle, wherein the recess for receiving an ultrasonic sensor is executed.

Furthermore, the present invention relates to an arrangement comprising a trim part for a vehicle, at least one ultrasonic sensor, and at least one above mounting panel, wherein in the trim part at least one recess is formed, the at least one ultrasonic sensor is held in the at least one recess, and the at least one Mounting panel is mounted in the region of at least one recess of the trim part.

In current vehicles, ultrasonic sensors are used to detect objects in an environment of the vehicle. Ultrasonic sensors typically cover a short range of a few meters around the vehicle. For complete detection of the environment, a plurality of ultrasonic sensors are usually positioned along all sides of the vehicle and evaluated together.

Sensor information of the ultrasonic sensors can be used in various driving support systems. Driving assistance systems already include widespread driver assistance systems that assist a driver in driving the vehicle. Such driver assistance systems include, for example, parking assist systems or distance warning systems, which are typically active at low speeds, and increasingly assistance systems that typically assist in driving at higher speeds, such as lane change assistance systems and blind spot assistance systems.

Based on the initial applications of ultrasonic sensors at low speeds, ultrasonic sensors and, for example, their holders are typically designed and integrated into the vehicle for low speeds, taking into account aerodynamic requirements and design requirements of the vehicle. The integration continues to be done at low speeds. These are typically speeds in the low double-digit range, for example up to 30 or 40 km / h.

However, the driving support systems are increasingly expanding through high-speed applications. High-speed driving refers to driving at a speed typical of highways and in particular highways, for example above 60 to 80 km / h or above 100 km / h. In principle, however, high-speed driving involves all journeys that are not covered by the typical low-speed applications.

It has been found to be problematic that can form turbulent flows around the panel of the vehicle, especially in a front and a rear portion of the vehicle. Thus, the turbulent flow around in the bumpers, which are a typical installation site for the ultrasonic sensors, and create problems there.

Due to the turbulent flow around the vehicle and its fairing parts strong local speed and pressure changes may occur in the field of installation locations of the ultrasonic sensors. This leads to turbulent behavior in an air boundary layer over the ultrasonic membrane. These turbulence effects provide for time varying local pressure fluctuations on the sensor membrane that produce ghost echoes, i. The ultrasonic membrane of the ultrasonic sensor is excited by the turbulences with an ultrasonic frequency, so that the sensor can perceive a signal as in a reflection of an ultrasonic pulse on an object. These turbulences can superimpose "real" reflection of ultrasonic pulses and make them invisible. In addition, the emission of the ultrasonic pulses is disturbed with the ultrasonic sensor. Overall, there is a poor detection of objects and other obstacles when driving at high speeds.

The turbulences are different in each case with different vehicles, for example, depending on a geometry of the vehicle, a local installation location of the ultrasonic sensors, or others. In addition, the hang Turbulence of various parameters, such as a vehicle speed and environmental conditions such as temperature, humidity and air density.

The driving assistance systems can also provide functions in autonomous vehicles to support an autonomous guidance of the vehicle.

In this context is from the DE 198 39 598 C2 a fastening sleeve for fastening a transducer to a plate known, in which the transducer is inserted and terminates in the installed position in front of the bumper. It has a circumferential, substantially annular projection whose height of the lateral surface varies over the circumference, wherein the front end face facing away from the bumper lies substantially in a plane running perpendicular to the longitudinal axis of the sleeve.

The DE 199 24 505 B4 relates to a fastening device for fastening ultrasonic transducers to a vehicle part, in particular a plastic part of a motor vehicle, in particular a bumper, with a holder receiving the ultrasonic transducer and with a provided on the plastic part for receiving the holder receiving portion, wherein the receiving portion has an opening and the holder their side facing the plastic part has a flange-like projection, on which on the side facing the plastic part, a projection is present. The projection is at least partially insertable from the side facing the holder in the receiving portion. The plastic part has an area adjacent to the breakthrough, the holder facing, flat contact area for surface contact with the approach.

Furthermore, from the EP 2 616 836 B1 an arrangement with a bumper for a vehicle and with an ultrasonic sensor, which is arranged on the bumper, known, wherein the ultrasonic sensor has a decoupling ring which extends in regions in a recess of the bumper. The ultrasonic sensor is arranged in particular on the bumper so that it extends at least partially into a recess in the bumper. It can be arranged in particular in the region of the recess in the bumper for detection by the recess. The recess may be formed in particular as a passage opening or as a blind hole. It may be formed, for example, as a passage opening, which is closed in particular on the outside of the bumper by a suitable cover. Such a cover member may be, for example, a thin wall portion of the bumper itself or a flexible film. The ultrasound sensor arranged on the bumper may in particular be part of a driver assistance device of a motor vehicle. The bumper is then in particular an outer lining element of the vehicle or motor vehicle.

Based on the above-mentioned prior art, the object of the invention is thus to specify an ultrasonic sensor for a vehicle for mounting in a recess of a trim part of the vehicle, which enables improved provision of sensor information when driving the vehicle, in particular during high-speed driving.

The object is achieved by the features of the independent claims. Advantageous embodiments of the invention are specified in the subclaims.

According to the invention, therefore, an ultrasonic sensor for a vehicle for mounting in a recess of a trim part of the vehicle is specified, with a cup-shaped diaphragm housing having an ultrasonic diaphragm formed in a bottom region thereof, and a decoupling ring annularly surrounding the diaphragm housing at its bottom region, wherein the decoupling ring is a wind deflector which is arranged and designed to generate turbulence in the recess mounted state when driving the vehicle in the area above the ultrasonic diaphragm.

According to the invention there is also provided an arrangement comprising a trim part for a vehicle, and at least one above ultrasonic sensor, wherein in the trim part at least one recess is formed, and the at least one ultrasonic sensor is held in the at least one recess.

Further, according to the invention a mounting panel for attachment in the region of a recess of a trim part of a vehicle is specified, wherein the recess for receiving an ultrasonic sensor is executed, and the mounting panel comprises a wind deflector, which is arranged and executed in the assembled state when driving the vehicle in the Area above the ultrasonic membrane to create a turbulence.

The invention also provides an arrangement comprising a trim part for a vehicle, at least one ultrasonic sensor, and at least one above mounting panel, wherein in the trim part at least one recess is formed, the at least one ultrasonic sensor is held in the at least one recess, and the at least one mounting panel in the field of at least one recess of the trim part is attached.

The basic idea of the present invention is therefore to change the air flow during the driving of the vehicle by the form of the decoupling ring or the mounting panel in such a way that turbulences constantly occur in the area above the ultrasound membrane. As a result, a behavior of the ultrasound sensor that is practically unpredictable as hitherto can only be brought about consistently by turbulence occurring only under certain conditions, which facilitates handling of the turbulences on the ultrasound diaphragm. Thus, for example, the turbulences can be easily filtered, or it can be easily adapted to the transmission behavior as well as the reception behavior of the ultrasonic sensor. Distinguishing between an operating state with turbulences in the region above the ultrasonic membrane and an operating state without such turbulences is not necessary. In this case, a slight loss of reception sensitivity compared to an operating state without turbulence can be compensated by a simple handling and control of the ultrasonic sensor over all operating conditions.

This is particularly effective when the turbulence is as uniform as possible and is influenced by as few boundary conditions as possible. Preferably, the turbulence is as independent as possible of a movement speed of the vehicle. A change in the characteristics of the ultrasonic sensor thus takes place only to a small extent.

The ultrasonic sensor can be designed differently as such. A piezoelectric element is typically coupled to the ultrasound membrane in order to generate ultrasonic pulses and to receive their reflections and convert them into electrical signals. The piezoelectric element is arranged on the inside of the ultrasonic membrane, i. inside in the pot-shaped membrane housing. Further, the pot-shaped membrane housing may be closed at the back, or the pot-shaped membrane housing is filled with a thermosetting material to hold the piezoelectric element and protect each.

The decoupling ring serves to decouple the ultrasound diaphragm from other components in terms of vibration engineering, i. in particular a trim part surrounding the ultrasonic membrane. The same applies if the ultrasonic sensor has a holder with which the membrane housing is held on the covering part. The holder can also extend into the recess of the trim part, so that the decoupling takes place here between the ultrasound membrane and the holder. The decoupling ring is arranged in this case between the ultrasonic diaphragm and the holder. The decoupling ring is preferably made of a soft-elastic material. In particular, the decoupling ring rests directly on an outer circumference of the ultrasound membrane.

The wind deflector can generate the turbulence when driving the vehicle in the area above the ultrasound diaphragm both by its arrangement on the vehicle as well as by its configuration. Various configurations and arrangements of the wind deflector are possible. Some possible embodiments of the wind deflector are given below.

The wind deflector generates the turbulences, in particular during high-speed driving, for example driving at a speed which is typical for highways and in particular highways, for example over 60 to 80 km / h or over 100 km / h. In principle, however, high-speed driving involves all journeys that are not covered by typical low-speed applications, such as parking.

With the mounting panel, a similar effect can be achieved as in the corresponding embodiment of the decoupling ring. However, it can be achieved by the use of the mounting panel that the ultrasonic sensors used itself need not be adjusted compared to the prior art. The object according to the invention of generating the turbulences in the region above the ultrasound membrane in the assembled state when driving the vehicle can thus be achieved in a very cost-effective manner using standard ultrasound sensors.

In an advantageous embodiment of the invention, the wind deflector is designed with at least one projection which protrudes in the recess mounted state relative to the trim part. By projecting against the cowling, an air flow along the cowling can be changed. This relates in particular to an attachment of the ultrasonic sensor to a lateral region of the vehicle. There, a design is preferred in the art for aerodynamic and optical reasons, which has as little air resistance. However, this has the above-mentioned disadvantages for the use of the ultrasonic sensors, so that the turbulence is generated specifically by the at least one projection. The wind deflector may have a single projection, which preferably has a width in the range of a diameter of the Ultrasonic membrane has. Alternatively, the wind deflector may comprise a plurality of projections which may be arranged distributed around the ultrasonic membrane. In principle, a plurality of projections may also be arranged only on one side of the ultrasound membrane.

In an advantageous embodiment of the invention, the at least one projection is designed in the manner of a spoiler. The spoiler has a slowly rising shape in the direction of travel. At the end of the spoiler usually creates a turbulence. The end of the spoiler thus preferably adjoins the bottom region with the ultrasound membrane formed therein, so that the turbulence is generated in this region.

In an advantageous embodiment of the invention, the at least one projection is designed in the manner of a storage element. The baffle element is arranged, for example, perpendicular to a surface of the trim part or to a flow direction. As a result, turbulence is already generated on its front side, ie its side facing the air flow. The turbulence preferably extends over the bottom area with the ultrasound membrane formed therein. For example, the at least one projection is formed uniformly on its front and rear sides.

In an advantageous embodiment of the invention, the at least one projection is designed like a knob. The projection is thus designed, for example, with a round or oval base surface and preferably extends vertically upwards from a surface of the decoupling ring. In this case, the knob-like projection on a typically small height, for example of a maximum of two millimeters

In an advantageous embodiment of the invention, the ultrasonic sensor has a plurality of knob-like projections. There are a plurality of knobs positioned with a free space next to each other to form the wind deflector. The space between the nubs can be chosen differently. Preferably, the free space is narrower than a width of the nubs. The plurality of nubs may be arranged in a circle around the ultrasound membrane. Particularly preferably, the nubs are evenly spaced along the surface of the decoupling ring.

In an advantageous embodiment of the invention, the wind deflector is arranged in the mounted state at a position in the direction of travel of the vehicle in front of the ultrasound membrane. The ultrasonic diaphragm is thus in the direction of travel behind the wind deflector. A turbulence in the region above the ultrasound membrane can thus be generated reliably.

In an advantageous embodiment of the invention, the at least one ultrasonic sensor is arranged in a holding element, and the holding element is attached to the lining part. With the holding member, the ultrasonic sensor can be easily used and attached to the cowling. In particular, the ultrasonic sensor may comprise, for example, a metallic diaphragm housing, and the retaining element may be made of plastic and have a receptacle for the diaphragm housing. Thus, the ultrasonic sensor can be easily and flexibly attached to the cowling. This is particularly advantageous for trim parts made of materials other than metal. Various trim parts such as bumpers and others are now increasingly made of plastic. Other, non-metallic materials, such as carbon or other, are increasingly being used to make trim parts.

In an advantageous embodiment of the invention, the mounting panel is designed for attachment to the ultrasonic sensor. As a result, the ultrasonic sensor can be produced independently of a configuration of the mounting panel. A special adaptation of the ultrasonic sensors over a mounting preparation for mounting the mounting bracket addition is not required, so that uniform ultrasonic sensors can be used independently of a vehicle or an attachment to the vehicle. The ultrasonic sensors can thus be manufactured inexpensively.

In an advantageous embodiment of the invention, the mounting panel is designed for attachment to the trim part of the vehicle. Preferably, the trim panel is designed accordingly, so that the mounting panel can be attached thereto. Such an embodiment of the mounting panel allows the ultrasonic sensor to be manufactured and mounted independently of the mounting panel. A special adaptation of the ultrasonic sensors is not required, so that uniform sensors can be used independently of a vehicle or an attachment to the vehicle. The ultrasonic sensors can thus be manufactured particularly cost-effectively. It can be used regardless of the use of the mounting panel identical ultrasonic sensors. Fairing parts are each manufactured vehicle-specific, so that an adjustment for mounting the mounting bracket in the design can be considered accordingly and is practically cost-neutral in the production.

In an advantageous embodiment of the invention, the at least one mounting panel is integral with the cowling. The mounting panel can thus already be provided with the trim part to facilitate the installation of the ultrasonic sensor. For example, the trim part can be made integral with the mounting panel. As a result, the trim part can be manufactured with the mounting panel in a single manufacturing step. This facilitates subsequent processing, such as painting, and attachment to the vehicle. Fairing parts are each manufactured vehicle-specific, so that an integral design with the mounting panel in the design of the trim parts can be considered accordingly and is virtually cost-neutral in the production.

In an advantageous embodiment of the invention, the at least one mounting panel and the cowling are made of a plastic material, and the at least one mounting panel is welded to the cowling. For example, the cowling may be a bumper of the vehicle, which is typically made of plastic. A corresponding mounting panel is preferably made of a same or at least similar plastic as the trim panel. For example, the trim part and the mounting panel may be made of a thermoplastic material.
