Definitions
- the present invention relates to an anti-trap device for a vehicle door or a hatch of a vehicle, with a sensor arrangement which has one sensor or a plurality of sensors, the sensor arrangement being set up to detect the presence or absence of a trapping event and the sensor arrangement being designed to distinguish between two or more Local areas for localizing the pinching event is set up.
- the invention further relates to a vehicle with such an anti-trap device.
- Such anti-trapping devices serve to prevent people or objects from being trapped when a vehicle door or hatch is closed manually or when the vehicle door or hatch is closed partially or fully automatically.
- a closing movement is aborted or an immediate opening movement is carried out in the opposite direction to the closing movement if a pinching event is detected. This is to avoid personal injury, property damage, or damage to the vehicle itself.
- An anti-trapping device of the type mentioned at the outset is known from document WO 2008/025422 A2.
- detection segments with different triggering thresholds are distinguished for a tailgate of a vehicle, for example, which are arranged close to a pivot axis or away from a pivot axis. In this way, the detection of erroneous pinching events and associated unnecessarily aborted closing processes are to be prevented.
- no statement can be made about the severity or severity of the pinching event in order to be able to assess and take into account a possible risk of injury to persons and a risk of damage to property.
- the invention is based on the technical problem of specifying an improved anti-trapping device for a vehicle, which can be operated more safely, in particular with the risk of injury to persons and the risk of damage to property being able to be reduced.
- the technical problem described above is solved in each case by the independent claims. Further configurations of the invention emerge from the dependent claims and the following description.
- the invention relates to an anti-trapping device for a vehicle door or a hatch of a vehicle, with a sensor arrangement which has one sensor or a plurality of sensors, the sensor arrangement being set up to detect the presence or absence of a trapping event, and the sensor arrangement being able to distinguish between two or more local areas for localizing the pinching event is set up.
- the anti-trap device is characterized in that the sensor arrangement is set up to differentiate between two or more load cases. Therefore, not only the location, but also the severity or severity of the trapping event can be detected in order to reduce the risk of injury to people and the risk of damage to property.
- a vehicle door or a hatch is mentioned here, it is in particular a displaceable or pivotable door or hatch of a vehicle.
- the vehicle door may be a door configured for personal access to a passenger compartment of a vehicle, such as a driver's door, a passenger door, or a rear door of a passenger vehicle.
- a flap can be set up to open and close a storage space, an engine compartment or a maintenance opening of a vehicle, such as a tailgate, a hood, a closure flap for a tank or charging interface or the like.
- a vehicle is mentioned here, it is in particular a motor vehicle or a commercial vehicle.
- the vehicle can in particular be a passenger car.
- Two or more load cases can be distinguished, for example, in that falling below a specified load threshold defines a first load case and reaching or exceeding the specified load threshold defines a second load case.
- n different load cases in particular up to twenty different load cases, are differentiated with respectively assigned load thresholds, it being possible for at least two load cases to be defined for each local area.
- up to ten different load cases, each with assigned load thresholds can be distinguished, with at least two load cases being able to be defined for each location.
- the load cases and their assignment to local areas can be stored in evaluation electronics that evaluate measured values of the sensor arrangement and in this way determine the presence or absence of a pinching event.
- the sensors for force and/or location determination described below can be resistive or capacitive sensors.
- a device for self-compensation and/or self-diagnosis can be assigned to each of the described sensors for force and/or position determination, in particular for compensating for temperature fluctuations and/or aging or fatigue effects and/or for determining the usability or maintenance requirement.
- At least one force sensor of the sensor arrangement can have a plastic profile, in particular a sealing profile, such as a rubber hose or the like, with at least one switching element, the switching element at least is encased in sections by a wall of plastic profile, and the switching element can be switched by compressing the plastic profile.
- a load threshold can be defined by a shape and/or Shore hardness of the plastic profile, in particular by a rigidity of the plastic profile.
- a compression of the plastic profile means in particular a local narrowing of a profile cross section of the plastic profile.
- the switching element can therefore be switched in particular by a local narrowing of a profile cross section of the plastic profile.
- the plastic profile can have been produced by extrusion or co-extrusion.
- the plastic profile can have a metal core for stiffening the plastic profile.
- the switching elements of the plastic profile can be embodied as guide elements and can be, for example, electrical conductors or lines which are connected to evaluation electronics on one or both sides and extend inside the plastic profile.
- the switching elements are at a distance from one another when there is no trapping event and contact one another locally at the location of the trapping event if there is a trapping event.
- At least one force sensor of the sensor arrangement can have a pressure hose with at least one pressure sensor.
- the pressure hose can in particular have a single pressure sensor.
- the pressure hose has two end-side pressure sensors on which a pressure medium of the pressure hose accommodated in an interior space of the pressure hose acts.
- the pressure medium can be ambient air or a gas or a gas mixture.
- both the position and the severity of a pinching event can be determined.
- the position of the dynamic trapping event can be determined based on the propagation times of the pressure pulse to the sensors.
- the measured amplitude allows conclusions to be drawn about the severity of the pinching event or the magnitude of the force of the pinching event.
- At least one force sensor of the sensor arrangement can be set up to measure a deformation of a structural component as a result of a force effect of a door drive, the force sensor being in particular a resistive, capacitive or inductive sensor.
- a spindle drive of a door drive can be supported on the structural component in order to measure the force exerted by the door drive during a closing process.
- a pinching event can be detected, for example, by a sudden increase in force and/or a load threshold being exceeded.
- Sensor signals can be evaluated by means of evaluation electronics.
- the sensor arrangement can have a plastic line segmented by guide elements in order to differentiate between two or more local areas for localizing the trapping event, with the guide elements differing in length.
- lengths or differences in length of the guide elements can specify lengths of local areas. If, for example, three local areas are to be differentiated, at least three guide elements of different lengths are provided, which can be contacted with another guide element that covers the entire length. The position of the trapping event can therefore be assigned to one of the local areas on the basis of the guide elements that have been contacted as a result of a trapping event. In particular, a local narrowing of the cross section of the plastic line can be detected as a pinching event.
- the conducting elements can simultaneously be the switching elements described above and, for example, be electrical conductors or lines which are connected to evaluation electronics on one or both sides and extend inside the plastic profile.
- the plastic line can therefore be part of a plastic profile or be a plastic profile.
- the sensor arrangement can have at least one high-impedance conducting element to distinguish between two or more local areas for localizing the trapping event. The resistance measured as a result of a trapping event allows conclusions to be drawn about the distance between the conductor connections of the high-impedance conducting element and the position of the trapping event. In particular, the position can be evaluated by means of a Wheatstone bridge.
- the sensor arrangement can have a plastic line segmented by high-impedance conductive elements to differentiate between two or more local areas for locating the trapping event, with the high-impedance conductive elements in particular having different lengths.
- the advantages of using high-impedance conducting elements can be combined with those of segmentation. Furthermore, improved compensation for signs of ageing, corrosion and fatigue and improved temperature compensation can be achieved with this arrangement.
- the sensor arrangement can have a plastic line segmented by resistors to distinguish between two or more local areas for localizing the trapping event.
- Two or more resistors can be distributed along a length of the plastic line, with a measured current or resistance enabling the position of the pinching event to be determined or enabling the position of the pinching event to be assigned to a local area.
- a plastic profile with guide elements and/or resistors can therefore be set up both for local resolution, i.e. in particular for assigning a pinching event to a local area, and for determining whether a load threshold has been reached or exceeded.
- the sensor arrangement can have at least one pressure hose with at least one pressure sensor to differentiate between two or more local areas for localizing the pinching event.
- the pressure hose has two end-side pressure sensors.
- a pressure pulse can be used to determine both the position and the severity of an entrapment event.
- the pressure hose can therefore be used for local resolution, ie in particular for assigning a pinching event a location area, as well as to determine whether a load threshold has been reached or exceeded.
- the invention relates to a vehicle with a vehicle door or a hatch and with an anti-trap device assigned to the vehicle door or the hatch, wherein the anti-trap device is designed in a manner according to the invention.
- At least part of the sensor arrangement can be part of a door seal of the vehicle door.
- a plastic profile described above can be a door seal or part of a door seal.
- the sensor arrangement can have at least two sensors, namely a force sensor for distinguishing between two or more load cases and a further sensor for distinguishing between two or more local areas for localizing the trapping event, such as a plastic profile described above.
- At least one force sensor is held on a structural component, in particular on a support plate, the structural component being coupled to a door drive for partially or fully automatically opening and/or closing the vehicle door and/or the force sensor is integrated into a power flow of the door drive.
- the door drive can have a spindle drive and one end of a spindle of the spindle drive can be held on the structural component.
- the force sensor can therefore be set up to measure reaction forces which the door drive exerts on the structural component.
- the structural component can in particular be connected to an A-pillar of the vehicle, in particular can be articulated.
- door drives that deviate from this can be provided, such as a rack and pinion drive, a drive in the hinge of the door or the like.
- the force sensor can be connected to evaluation electronics of the vehicle.
- the evaluation electronics can be set up in the manner described above for evaluating sensor signals.
- the evaluation electronics can be set up to interrupt a closing movement and/or to carry out an opening movement in the opposite direction to the closing movement if a trapping event is detected.
- the evaluation electronics can be set up to trigger an optical or acoustic warning signal or an emergency call as a result of a trapping event being detected.
- the evaluation electronics can be set up to initiate active countermeasures in the event that a trapping event is detected in order to end the trapping, and/or be set up to trigger passive countermeasures, such as the aforementioned warning signals or an emergency call.

- the evaluation electronics can be set up to detect the severity of a collision of the vehicle using the force sensor, in which measured forces are converted to a collision area.
- the evaluation electronics can be set up to send an emergency call or to activate warning signals of the vehicle, in particular optical or acoustic warning signals, if a collision is detected.

- FIG. 1B shows a vehicle door of the vehicle from FIG. 1A;
- FIG. 2A shows a first sensor;
- FIG. 3A shows the sensor arrangement from FIG. 1A in a further view
- FIG. 3B shows the sensor arrangement from FIG. 1A in a further view.
- the vehicle 1A shows a vehicle 2.
- the vehicle 2 is a passenger car 2.
- the vehicle 2 has a vehicle door 4.
- the vehicle 2 has an inventive anti-trap device 6 assigned to the vehicle door 4.
- the anti-trap device 6 has a sensor arrangement 8 .
- the sensor arrangement 8 is set up to detect the presence or absence of a pinching event.
- the sensor arrangement is set up to differentiate between two or more load cases.
- the sensor arrangement 8 has a force sensor 10.
- the sensor arrangement 8 is set up to differentiate between five local areas A0-A4 for locating the pinching event, which are shown in FIG. 1B.
- the sensor arrangement 8 has a plastic profile 12 .
- the plastic profile 12 is at the same time a sealing profile 12 or a door seal 12.
- the plastic profile 12 cannot be a sealing profile, so that an additional door seal can be provided.
- the plastic profile 12 forms a further sensor 12 of the sensor arrangement 8.
- the plastic profile 12 can be formed all the way around, so that all local areas A0-A4 can be detected with the plastic profile 12. Alternatively, provision can be made for two or more plastic profiles 12 to be lined up in order to cover the spatial regions A0-A4 to be differentiated for the detection of trapping events.
- plastic profiles 12 are described schematically with reference to FIGS. 2A-2H, which enable trapping events to be assigned to local areas and can therefore be used as plastic profile 12 according to FIG. 1B.
- FIG. 2A shows a variant of a deformable plastic profile 12, the plastic profile 12 having a plastic line 20 segmented by guide elements 14, 16, 18. A longitudinal extension of the plastic profile 12 runs in the x-direction.
- a first segment A1 forms, for example, the local area A1 according to FIG. 1B.
- a second segment A2 forms, for example, the local area A2 according to FIG. 1B.
- a third segment A3 forms the local area, for example A3 according to Fig.
- a pinching event i.e. a local compression in the y-direction, leads e.g. in the area A3 to the fact that the conducting element 14 contacts a conducting element 22 to which a measuring voltage is applied, so that between the electrical connections SO and S3 e.g. a current or a current rise is measurable.
- a pinching event i.e. a local compression in the y-direction, leads e.g current rise is measurable.
- a pinching event ie a local compression in the y-direction, leads, for example, in the area A1 to the conducting elements 14, 16, 18, 22 contacting one another, so that between the electrical connections SO and S1, SO and S2 and SO and S3 eg a current or a current increase can be measured.
- the result is therefore the following evaluation logic for detecting a pinching event in one of the areas A1, A2 or A3:
- pinch events can be assigned to the local areas.
- the guide elements 14, 16, 18, 22 are at the same time switching elements 14, 16, 18 which, given a known rigidity of the plastic profile 12 in the y-direction, also enable detection of a load threshold being reached or exceeded. In this way, the plastic profile 12 can at least be used to distinguish whether a predetermined load threshold has been reached or exceeded, but without measuring the exact amount of a statically or dynamically acting force.
- the plastic profile has a high-impedance resistance element 24.
- the high-impedance resistance element is connected on two sides, namely with the terminals R0 and R1.
- a distance along the x-axis up to a pinching event i.e. a local compression in the y-direction, can be determined, at the position of which the conducting element 22, to which the measurement voltage is applied, the high-impedance Resistance element contacted.
- the evaluation can be carried out using a Wheatstone bridge.
- the arrangement according to FIG. 2B forms a voltage divider, so that the respective partial distances to the location of the trapping event can be precisely determined. Since relative resistance values are evaluated here, this arrangement is particularly robust with regard to aging phenomena, such as, for example, a contact resistance that increases as a result of aging. Such an aging-related increasing contact resistance is automatically compensated based on the evaluation of the relative resistances of the voltage divider.
- the guide elements 22, 24 are at the same time switching elements 22, 24 which, given a known rigidity of the plastic profile 12 in the y-direction, also enable detection of a load threshold being reached or exceeded. In this way, the plastic profile 12 can at least be used to distinguish whether a predetermined load threshold has been reached or exceeded, but without measuring the exact amount of a statically or dynamically acting force.
- FIG. 2C shows a further variant of a deformable plastic profile 12, which represents a combination of the arrangement from FIG. 2B with a further guide element 26.
- the guide elements 22, 24, 26 are at the same time switching elements 22, 24, 26 which, when the rigidity of the plastic profile 12 in the y-direction is known, also enable detection of a load threshold being reached or exceeded. In this way, the plastic profile 12 can at least be used to distinguish whether a predetermined load threshold has been reached or exceeded, but without measuring the exact amount of a statically or dynamically acting force.
- FIG. 2D shows a further variant of a deformable plastic profile 12.
- the variant according to FIG. 2D is a combination of the segmented arrangement according to FIG. 2A and the use of a high-impedance conducting element according to FIG. 2B.
- three high-impedance conducting elements 28, 30, 32 of different lengths are provided, which are each contacted on two sides—namely with the connections S1/S1-1, S2/S2-1 and S3/S3-1.
- the plastic profile 12 is shown broadened, viewed in the y-direction, merely to illustrate the arrangement of the guide elements. It goes without saying that the guide element 12 according to FIG. 2D, like the examples described above and described below, is also an elongate plastic profile, which can be designed in particular in the area of a door seal or as part of a door seal of a motor vehicle.
- the guide elements 22, 28, 30, 32 are at the same time switching elements 22, 28, 30, 32 which, when the rigidity of the plastic profile 12 in the y-direction is known, also enable detection of a load threshold being reached or exceeded. So can be distinguished by means of the plastic profile 12 at least whether a specified load threshold is reached or exceeded, but without measuring the exact amount of a statically or dynamically acting force.
- Fig. 2E shows another variant of a deformable plastic profile 12.
- the plastic profile according to FIG. 2E corresponds to the plastic profile according to FIG the length of the area A1 is insulated (insulation 21).
- the insulation 19, 21 results in the following evaluation logic for detecting a pinching event in one of the areas A1, A2 or A3:
- Fig. 2F shows another variant of a deformable plastic profile 12.
- the plastic profile according to FIG. 2F corresponds to the plastic profile according to FIG the length of the area A1 is insulated (insulation 21).
- FIG. 2G shows a further variant of a deformable plastic profile 12.
- the plastic profile 12 according to FIG. 2E is designed as a pressure hose 12 and has a first pressure sensor P1 and a second pressure sensor P2.
- the pressure hose 12 is sealed off from the environment and filled with a pressure medium, such as air. According to alternative configurations, only one pressure sensor can be provided on the pressure hose.
- a local pinching event in the y-direction generates an impulse that is transmitted bilaterally in the print medium in the direction of sensors P1 and P2.
- the amplitude of the measured signal allows conclusions to be drawn about the severity or severity of the pinching event, so that, for example, reaching or exceeding a predetermined force threshold can be detected.
- Fig. 2H shows another variant of a deformable plastic profile 12. To differentiate between the local areas A1, A2 and A3, resistance elements 34, 36, 38 are arranged along a guide element 39, with a pinching event being assigned to a respective local area A1, A2 or A3 based on the measured resistance can be.
- the guide elements 22, 39 are at the same time switching elements 22, 39 which, when the rigidity of the plastic profile 12 in the y-direction is known, likewise enable detection of a load threshold being reached or exceeded. In this way, the plastic profile 12 can at least be used to distinguish whether a predetermined load threshold has been reached or exceeded, but without measuring the exact amount of a statically or dynamically acting force.
- FIG. 3A shows a further view of the anti-trap device 6 and the sensor arrangement 8 according to FIG. 1A with the vehicle door 4 open with a view of an A-pillar 40 of the vehicle 2 to which the vehicle door 4 is connected in an articulated manner.
- the plastic profile 12 is set up to differentiate between the local areas A0, A1, A2, A3, A4 in order to localize a pinching event when the vehicle door is closed.
- the force sensor 10 (FIG. 3B) is used to distinguish between two or more load cases.
- the force sensor 10 is set up to measure an absolute value of an acting force in a predetermined measuring range.
- the force sensor 10 is held on a support plate 42 .
- the support plate 42 is a structural component 42.
- the support plate 42 is coupled to a door drive 44 for partially or fully automatically opening and/or closing the vehicle door 4.
- the door drive 44 has a spindle 46 and a spindle drive 48.
- different door drives can be provided, such as a rack and pinion drive, a drive in the hinge of the door or the like.
- One end 50 of the spindle 46 is held on the support plate 42 .
- the acting forces are supported on the support plate 42 and can be detected by the force sensor 10 be measured.
- the force sensor 10 is integrated into a force flow of the door drive. According to alternative configurations, the force sensor can therefore also be installed in a different position or, for example, be part of one of the screws shown.
- the support plate 42 is formed from a steel material.
- support plate 42 is secured by four bolted connections 52 .
- the force sensor is connected to evaluation electronics 56 of vehicle 4 via a plug 54 (FIG. 1A).
