Abstract
Description
Technical Field
[0001] The invention relates to a seat occupancy arrangement for determining an occupancy state of a seat in a vehicle having the features of the preamble of claim 1. The invention also relates to a method for determining an occupancy state of a seat and to a corresponding vehicle. Background Art
[0002] In vehicles, the occupancy of seats is often detected, for example, to be used to output a corresponding seat belt warning when the seat belt is not worn. Seat detection devices that are integrated into the seat and work based on pressure sensors are reliable, but costly.
[0003] Furthermore, it is known to carry out a camera-based seat occupancy determination, wherein the seat occupancy determination is carried out via digital image processing.
[0004] Patent document WO2013 / 071986A1 proposes another method, which suggests a method for determining the occupancy of at least one seat in a motor vehicle, wherein at least one inclination information is determined, and the inclination information describes a certain time trend and / or change of the inclination of the motor vehicle with respect to the longitudinal axis and / or transverse axis of the motor vehicle, wherein the inclination information is used to determine seat occupancy information, which describes that a seat in the motor vehicle is occupied by an object. Summary of the invention
[0005] The object of the present invention is to propose a seat occupancy component which enables an improved detection of the seat occupancy state and to propose a corresponding method. The object is achieved by a seat occupancy component having the features of claim 1, by a method having the features of claim 9 and by a vehicle having the features of claim 10. Preferred or advantageous embodiments of the invention are revealed in the dependent claims, the subsequent description and the drawings.
[0006] One subject of the invention is a seat occupancy arrangement which is suitable and / or designed for determining an occupancy state of a seat in a vehicle.
[0007] The vehicle is designed, for example, as a passenger car and has a vehicle seat on which a person can sit.
[0008] The seat occupancy state can be configured as an occupied seat occupancy state or an unoccupied seat occupancy state. In the unoccupied seat occupancy state, the corresponding vehicle seat is empty; in the occupied seat occupancy state, the corresponding vehicle seat is occupied by a person. The person can be an adult or a child placed in a child seat or a child between three and six years old. Alternatively, instead of a person, an animal or another object can be identified.
[0009] The seat occupancy component has a camera device, which is particularly designed and / or arranged for detecting the interior of the vehicle. The camera device is particularly understood to be a sensor device for location resolution. In particular, the camera device is designed as at least one interior camera. The camera device can be designed as a grayscale camera, an RGB camera, an IR camera, an RGB-IR camera or a ToF camera (Time-of-Flight). The camera device can also realize other functions, such as drive monitoring, driver observation. For example, the camera device is arranged and / or can be arranged on the interior rearview mirror of the vehicle. Optionally, the camera device is designed to be movable by a motor.
[0010] The camera device is designed to detect a person in a seat based on camera-supported seat occupancy data. In the simplest design, the camera-supported seat occupancy data can be designed as a camera image of the seat with or without a person. It is also possible that the camera-supported seat occupancy data is already designed as metadata, which is derived from the camera image. The camera-supported seat occupancy data in particular includes seat occupancy information for the seat.
[0011] In addition, the seat occupancy component comprises a buffer detection device for detecting the state of at least one buffer of the vehicle. The buffer of the vehicle is in particular designed as a shock absorber and is assigned to one of the wheels. The state of the at least one buffer of the vehicle forms the basis for the seat occupancy data supported by the buffer. The seat occupancy data supported by the buffer can be formed based on the state of exactly one buffer of the vehicle, instead of detecting the states of a plurality of buffers. Particularly preferably, the state of two buffers of a common axle is detected. The detection of the state of two buffers of a common axle has the advantage that vehicle roll information can be derived, which is particularly convincing with regard to seat occupancy in the vehicle.
[0012] The seat occupancy data supported by the buffers can in particular describe the degree of cushioning of the respective buffer. The degree of cushioning of the buffer depends on the mass to be cushioned and therefore on the vehicle plus the persons in the vehicle. In the event of a person boarding the vehicle, the mass is increased and the degree of cushioning changes, in particular it is reduced. Since the buffers are assigned to the seats, a location resolution is achieved, so that a change in the degree of cushioning can be assigned to a seat. The seat occupancy data supported by the buffers can be in the form of raw data, but can also be metadata, which are derived from the raw data.
[0013] The seat occupancy module has an evaluation device for determining the seat occupancy state in the vehicle. The evaluation device is in particular designed as a digital data processing device. The evaluation of the raw data of the buffer detection device and / or the camera device can be carried out selectively in the buffer detection device or in the evaluation device or in another data processing device.
[0014] In the context of the invention, it is proposed that the evaluation device is designed to determine the seat occupancy state based on the camera-supported seat occupancy data and the buffer-supported seat occupancy data, at least in some situations. In particular, the seat occupancy state is determined—preferably only—for vehicle seats that are at least partially obscured, for example, by the front seats, in particular by the driver's seat and / or the front passenger seat (as interfering contours in the field of view of the camera device). Specifically, the seat occupancy state is determined—preferably only—for the rear lateral vehicle seats.
[0015] The present invention takes into account that the two detection methods for determining the seat occupancy state have advantages and disadvantages:
[0016] Therefore, the seat occupancy state can be reliably detected only in certain situations by means of the seat occupancy data supported by the buffer, for example when the vehicle is stationary and especially when people are getting on and off the vehicle. In contrast, many interfering influences occur during vehicle travel, so that it cannot be ruled out that the determination of the seat state solely by means of the seat occupancy data supported by the buffer does not provide sufficient confidence.
[0017] On the other hand, the determination of the seat occupancy state by means of camera-assisted seat occupancy data is very reliable, provided that the person sitting in the seat is not obscured by interfering contours. If, for example, the rear lateral seats in a vehicle are examined and the camera device is centrally mounted, for example on the interior rearview mirror, these seats are usually obscured by the driver's seat and the front passenger seat as interfering contours. It cannot therefore be ruled out that a person is sitting in the seat and is nevertheless not in the field of view of the camera device.
[0018] Against this background, it is proposed to use camera-assisted seat occupancy data and buffer-assisted seat occupancy data in the determination of the seat occupancy state in order to increase the process reliability of this determination.
[0019] In a preferred embodiment of the invention, the evaluation device is designed to evaluate the camera-supported seat occupancy data and the buffer-supported seat occupancy data simultaneously and / or in parallel. For example, it is in principle possible to examine the two seat occupancy data as a time series and to evaluate and determine the seat occupancy state by joint evaluation. Alternatively, it is also possible to use artificial intelligence, such as a neural network, in the evaluation and to determine the seat occupancy state in this way.
[0020] In a preferred embodiment of the invention, the evaluation device is designed to carry out a camera-based evaluation of the camera-assisted seat occupancy data and to determine an occupied or unoccupied camera seat occupancy state as a result.
[0021] In this case, it is preferred that the starting point is that for the case where the camera sub-evaluation yields the result that there is an occupied camera seat occupancy state, the occupied camera seat occupancy state is simultaneously further used as the occupied seat occupancy state. This evaluation reflects the idea that the camera device and / or the seat occupancy data supported by the camera are already very convincing and reliable in themselves in the case of a positive detection of a person in the seat.
[0022] In the case where the camera sub-evaluation yields the result that an unoccupied camera seat occupancy state exists, then, as will be explained further below, this unoccupied camera seat occupancy state is checked and / or verified by means of the seat occupancy data supported by the buffer.
[0023] As an alternative or in addition, the evaluation device is designed to perform a buffer sub-evaluation of the seat occupancy data supported by the buffer and determine an occupied or unoccupied buffer seat occupancy state or a buffer seat occupancy change as a result. Thus, for example, on the one hand, an occupied or unoccupied buffer seat occupancy state can be inferred by the buffer sub-evaluation via the absolute value of the buffer degree and / or the absolute position of the buffer. As an alternative or in addition, a change in the buffer degree of the buffer and / or a change in the absolute position of the buffer is detected and the buffer seat occupancy change is determined in this way. Thus, when a person gets on the vehicle, the buffer is compressed, so that the buffer degree is reduced and / or the absolute height position of the buffer is changed. In the same way, when a person gets off the vehicle, the buffer is unloaded, so that the buffer degree is increased and / or the absolute height position of the buffer is changed. In particular, getting on and off the vehicle can be detected and evaluated particularly easily via the buffer seat occupancy change.
[0024] Thus, the camera seat occupancy state as well as the buffer seat occupancy state and / or the buffer seat occupancy change may be taken into account when determining the seat occupancy state.
[0025] It is particularly preferred that the evaluation device is configured to determine the occupied seat occupancy state when the camera seat is occupied, and to determine the seat occupancy state according to the buffer seat occupancy state and / or to change the seat occupancy state according to a change in the buffer seat occupancy state when the camera seat is unoccupied. In the case where there is an unoccupied camera seat occupancy state, the evaluation device can first use the seat occupancy data supported by the buffer and in particular use the result of the buffer sub-evaluation. In the case where the buffer sub-evaluation results in an occupied buffer seat occupancy state, the seat occupancy state is also placed on the occupied seat occupancy state. As an alternative or in addition, it can be provided that when there is a change in the buffer seat occupancy state, the seat occupancy state is determined or changed according to a change in the buffer seat occupancy state. If the change in the buffer seat occupancy state means getting off the vehicle, the unoccupied seat occupancy state is determined. If the change in the buffer seat occupancy state means getting on the vehicle, the occupied seat occupancy state is determined.
[0026] In one possible embodiment, the seat occupancy state is determined when a person exits the vehicle. First, the occupied seat occupancy state is determined in the occupied camera seat occupancy state. After the transition to the unoccupied camera seat occupancy state, the seat occupancy state is determined based on the buffer seat occupancy state and / or based on the change in the buffer seat occupancy state when the person exits the vehicle. In this way, it can be distinguished whether the person actually exits the vehicle or only moves to an area of the seat that can no longer be detected by the camera device. Thus, possible error sources when determining the seat occupancy state solely by the camera device are compensated.
[0027] Alternatively or additionally, the evaluation device is designed to determine the seat occupancy state during the boarding process. In this case, it is provided that, in the case of an unoccupied camera seat occupancy state, the seat occupancy state is determined as an occupied seat occupancy state independently of the camera seat occupancy state based on the buffer seat occupancy state and / or based on a change in the buffer seat occupancy state when a person boards the vehicle. The occupied seat occupancy state can then be confirmed and / or verified by the occupied camera seat occupancy state. Thus, a possible error source, namely a late recognition of the occupied camera seat occupancy state, is compensated by using the seat occupancy data supported by the buffer.
[0028] In a further advantageous embodiment, the method already mentioned can be used to determine whether a child is present as a person even in a rearward-oriented child seat. This cannot be detected by the camera due to the orientation. In addition, it can be determined whether an adult has placed a child or infant in the seat or removed it from the seat. In an advantageous embodiment, the weight of the empty child seat can be stored or detected.
[0029] In a preferred embodiment of the invention, the evaluation device is designed to determine the buffer seat occupancy state and / or the buffer seat occupancy state change based on a threshold value and / or based on pattern recognition. By means of this robust determination method, the buffer seat occupancy state or the buffer seat occupancy state change can be determined particularly reliably.
[0030] After a possible false recognition due to loading of the luggage compartment (false positive seat occupation recognition), it is preferably provided that when opening the tailgate, the damping levels of all four dampers are taken into account and the mode of luggage compartment loading is clearly identified and accordingly ignored. For example, when loading the luggage compartment, the two rear dampers are loaded more strongly in relation to the front dampers (pitch angle of the vehicle) than when entering the vehicle on the rear seats.
[0031] Another subject of the present invention relates to a method for determining a seat occupancy state in a vehicle, preferably using a seat occupancy component as already described above, wherein seat occupancy data supported by a camera are ascertained by a camera device and seat occupancy data supported by a buffer are ascertained by a buffer detection device, and the seat occupancy state is determined based on the seat occupancy data supported by the camera and the seat occupancy data supported by the buffer, as already described above.
[0032] Another subject matter is constituted by a vehicle comprising the seat occupancy assembly. BRIEF DESCRIPTION OF THE DRAWINGS
[0033] Other features, advantages and effects of the present invention are obtained from the subsequent description of the preferred embodiments of the present invention.
[0034] Figure 1 A schematic block diagram of a vehicle as an embodiment of the present invention is shown.
[0035] Corresponding or identical components are provided with the same reference symbols in the figures. DETAILED DESCRIPTION
[0036] Figure 1 A schematic top view of a vehicle 1 with a seat occupancy arrangement 2 is shown as an exemplary embodiment of the invention. The vehicle 1 is designed as a passenger car, for example, and has a driver's seat 3 and a front passenger seat 4 in the front area. Three seats 5a, 5b, 5c are depicted in the rear area, wherein the seats 5a, 5b are arranged laterally in the direction of travel, behind the driver's seat 3 and the front passenger seat 4. For orientation in the vehicle 1, an interior rearview mirror 6 is depicted, which is arranged centrally in the vehicle 1.
[0037] The vehicle 1 , in particular the seat occupancy arrangement 2 , has a camera device 7 , which is designed as an interior camera. In this exemplary embodiment, the camera device 7 is arranged centrally in the region of the interior rearview mirror 6 and observes the interior of the vehicle 1 .
[0038] The vehicle 1 includes shock absorbers 8a, 8b, 8c, and 8d, and each shock absorber 8a, 8b, 8c, and 8d damps and / or springs the vehicle body of the vehicle 1. For example, each shock absorber 8a, 8b, 8c, and 8d includes a spring and a shock absorber.
[0039] The vehicle 1 and in particular the seat occupancy component 2 have buffer detection devices 9a, 9b, 9c, 9d, which are selectively assigned to the buffers 8a, 8b, 8c, 8d and by which, for example, the height position and / or the degree of buffering are recorded.
[0040] The seat occupancy module 2 has an evaluation device 10 which is connected in terms of data technology to at least one of the individual bumper detection devices 9a, 9b, 9c, 9d and the camera device 7. The vehicle 1 and / or the seat occupancy module 2 comprises a seat belt warning device 11 which is connected in terms of data technology to the evaluation device 10 and which outputs or can output a seat belt warning for each seat 3, 4, 5a, 5b, 5c in conjunction with the seat belt state based on the determination of the seat occupancy state by the evaluation device 10.
[0041] The seat occupancy module 2 is designed to determine the seat occupancy status in the vehicle 1 , in particular for determining the seat occupancy status of the rear lateral seats 5 a , 5 b .
[0042] The determination of the seat occupancy status is based on the detection of the camera device 7, wherein the detection or non-detection of a person in the seat 3, 4, 5a, 5b, 5c forms the basis for the camera-assisted seat occupancy data. In particular, boarding and exiting processes are detected by the sensor fusion of the camera device 7 and the bumper detection devices 9a, 9b, 9c, 9d.
[0043] As can be seen from the top view of the vehicle 1, the field of view 12 of the camera device 7, in particular the field of view of the rear lateral seats 5a, 5b, is limited by the driver's seat 3 and the front passenger seat 4, because the driver's seat and the front passenger seat form an interfering contour in the field of view 12. Therefore, when determining the seat occupancy based on the camera, the recognition of the boarding process or the exiting process in the seats 5a, 5b outside the rear seat row is problematic because they are blocked by the front seats 3, 4. This is particularly problematic in the case of small people (5% ladies). For the seat belt warning function of the seat belt warning device 11, a rapid reaction time of 2 seconds is specified for boarding and a rapid reaction time of 1 second is specified for exiting. In particular, in the case of small people, it may take a long time until the person is visible in the field of view 12 of the camera device 7 (due to the blockage).
[0044] In addition, the state of at least one buffer 8a, 8b, 8c, 8d is detected by a buffer detection device 9a, 9b, 9c, 9d, forming the basis for seat occupancy data supported by the buffer, wherein the seat occupancy component 2 is configured to determine the seat occupancy state in the vehicle 1 in part based on the seat occupancy data supported by the buffer.
[0045] It should be emphasized that the evaluation of the measurement data of the camera device 7 or the buffer detection devices 9a, 9b, 9c, 9d can be carried out locally, centrally, remotely, in the cloud, in the evaluation device 10 or in any other digital data processing device which is digitally connected to the seat occupancy component 2.
[0046] It can be provided that the evaluation device 10 is designed to carry out a camera-based evaluation of the camera-supported seat occupancy data. In this case, in particular, the camera image of the camera device 7 is evaluated by means of digital image processing, and an occupied camera seat occupancy state or an unoccupied camera seat occupancy state is determined based on the camera image thus evaluated as camera-supported seat occupancy data.
[0047] The evaluation device 10 is designed to perform a buffer-based evaluation of seat occupancy data supported by the buffer. In this case, it is taken into account that when a person enters the vehicle 1, the corresponding buffer 8a, 8b, 8c, 8d changes. When evaluating the seat occupancy data supported by the buffer, on the one hand, the absolute height position of the buffer 8a, 8b, 8c, 8d can be evaluated. As an alternative or in addition, it is possible to determine the degree of cushioning of the corresponding buffer 8a, 8b, 8c, 8d. The mentioned measured variables change depending on the occupancy of the seat 3, 4, 5a, 5b, 5c. As an alternative or in addition, it is possible to evaluate the change of the state of the buffer 8a, 8b, 8c, 8d, especially when boarding or when getting off the vehicle. During the boarding process or the getting off process, there is a spring compression or spring extension of the buffer 8a, 8b, 8c, 8d, wherein the change of the buffer seat occupancy state can be determined by the change of the state of the corresponding buffer 8a, 8b, 8c, 8d.
[0048] The evaluation device 10 is designed in particular to determine the seat occupancy status based on a camera seat occupancy status and based on a buffer seat occupancy status and / or a buffer seat occupancy status change. Thus, the camera-based seat occupancy determination for the rear outer seats 5a, 5b in combination with the measured cushioning levels of the cushions 8a, 8b, 8c, 8d allows the detection of dynamic and / or static changes in the cushioning levels when boarding or exiting the vehicle.
[0049] Evaluate the disembarkation process in stages:
[0050] During the exit process, the people on seats 3, 4, 5a, 5b, 5c and especially the people on the rear side seats 5a, 5b are first detected by the camera device 7, so that the occupied camera seat occupancy state and thus the occupied seat occupancy state are determined. As long as the people on seats 5a, 5b are identified based on the camera, the result of the camera device 7 is used.
[0051] During the process of getting off the vehicle, it is possible that a person, especially in the case of the rear side seats 5a, 5b, walks to the outside of the vehicle 1, so that the person can no longer be detected by the camera device 7 and there is an unoccupied camera seat occupancy state. During the process of getting off the vehicle, the seat occupancy state is not directly converted to the unoccupied seat occupancy state. In more cases, the buffer seat occupancy state or the buffer seat occupancy state change is taken into account, so that the unoccupied seat occupancy state is determined by the evaluation device 10 only when the buffer seat occupancy state or the buffer seat occupancy state change determines the unoccupied buffer seat occupancy state. Therefore, after the person disappears from the field of view 12 of the camera device 7, waiting is carried out until the person's getting off the vehicle is also determined based on the seat occupancy data supported by the buffer. Until this moment, the seat occupancy state remains occupied. If the person on the seat 5a, 5b is no longer visible, the degree of buffering is evaluated. When the load drop of the shock absorber 8a, 8b, 8c, 8d on the corresponding side is detected, it is recognized that the person has gotten off the vehicle.
[0052] Evaluate the boarding process in stages:
[0053] As long as it is detected based on the camera that there is no one on the seat and the load of the shock absorber 8a, 8b, 8c, 8d is constant, the seat occupancy is interpreted as “no one” and / or unoccupied. During the boarding process, it can happen that a person, especially in the case of the rear side seats 5a, 5b, is first positioned so that the person is outside the field of view 12 of the camera device 7, so that an unoccupied camera seat occupancy state is determined by the evaluation device 10 based on the seat occupancy data supported by the camera. However, the occupied buffer seat occupancy state is determined by the buffer-supported seat occupancy data about the buffer seat occupancy state, or according to the buffer seat occupancy state change, and this buffer seat occupancy state is interpreted by the evaluation device 10 as an occupied seat occupancy state. It is also conceivable that a person arrives in the field of view 12 of the camera device 7, so that the occupied camera seat occupancy state is also detected by the evaluation device 10 and the occupied seat occupancy state is thus verified. When the carrier of the shock absorber 8a, 8b, 8c, 8d on the corresponding side is detected to be raised, this change is interpreted as a person boarding the vehicle. Camera-based verification takes place as soon as it is visible in the detection range of the camera device 7. Threshold values and pattern recognition for the damper loads are used to detect entry or exit processes (eg short supports outside the vehicle should not be detected as entry).
[0054] Camera-based seat occupancy recognition is used as an enabler for the function of the seat belt warning by the seat belt warning device 11. For example, the camera device 7 can be an interior camera (RGB-IR, IR or ToF) on the interior rearview mirror 6, which covers the entire interior (for driver monitoring, seat occupancy recognition functions) and can be (movably) mounted. With the help of such a camera device 7 and the buffer information, a camera-based determination of the seat occupancy can be achieved for all seats. By using the buffer information as seat occupancy data supported by the buffer, a fast initial recognition can be achieved, which is supplemented by the camera information.
