Definitions
- the invention relates to devices and methods for controlling a passenger airbag of a vehicle.
- Document DE 10 2017 000 734 A1 discloses a detection of objects on the passenger seat of a vehicle and controls the passenger airbag depending on the detected objects.
- the airbag is switched on.
- the airbag is switched off.
- Document DE 69431 667 T2 discloses a deactivation of the passenger airbag when a child seat without a child and a rear-facing child seat are detected. The detection is carried out with the help of distance sensors.
- Document US 6,608,910 Bl discloses the classification of objects on the passenger seat into "adult person”, “forward-facing child seat” and “rear-facing child seat”.
- Document US 2006 0030988 Al discloses a camera of a vehicle for detecting children in the interior.
- a purely weight-based distinction between empty seat, empty child seat, child in child seat, child in baby seat and adult person is becoming increasingly inaccurate due to increasingly heavy and diverse child seat systems.
- Increasingly flexible (forward/backward, isofix/vehicle belt) child seats and those approved for a very wide range of weights are further exacerbating the problem.
- the invention is based on the knowledge that the risk of injury in serious crashes can be reduced by reactivating the airbags for larger forward-facing children.
- the orientation of the child seat and precise separation of the children's sizes can be determined with great difficulty using seat sensors alone. A possible reactivation of the airbags in serious crashes cannot be carried out due to this uncertainty.
- the object of the invention to provide a device and a method for controlling a passenger airbag of a vehicle, which increase the accuracy of the detection of objects on the passenger seat.
- the proposed device for controlling a passenger airbag of a vehicle according to claim 1 uses a two-stage and according to claim 3 a double detection principle with the aid of a sensor unit in the passenger seat and image processing of a camera image. This improves the exact and correct classification, in particular of children in child seats, so that, for example, in the event of serious crashes and for children older than 6 or older than 10 years in forward-facing child seats, the passenger airbag can be reactivated, even if the passenger airbag is deactivated when a child in the child seat is detected on the passenger seat.
- a control parameter is generated, which is preferably transmitted to an airbag control unit.
- the airbag control unit can then reactivate the passenger airbag depending on the control parameter and preferably on further parameters, in particular based on measured values from collision sensors, even if a child has been detected on the passenger seat.
- a safe classification of children in the front passenger seat is thus possible even if no clear classification is possible using the sensor unit in the front passenger seat to determine the weight when this sensor unit is used conventionally.
- the proposed device for controlling a passenger airbag of a vehicle uses image processing of a camera image from an interior camera to classify objects on the passenger seat of the vehicle. This improves the exact and correct classification of children in child seats in particular, so that, for example, in the case of serious crashes and children older than 6 or older than 10 years in forward-facing child seats, the passenger airbag is reactivated, even if the passenger airbag is deactivated when a child is detected on the passenger seat. This reduces the risk of serious injuries to children in the passenger seat in the event of serious crashes.
- a control parameter is generated, which is preferably transmitted to an airbag control unit.
- the airbag control unit can then reactivate the passenger airbag depending on the control parameter and preferably depending on further parameters, in particular based on measured values from collision sensors, even if a child has been detected on the passenger seat
- the sensor unit integrated into the passenger seat is in particular a capacitive or pressure-sensitive sensor mat, which is preferably integrated into the seat cushion of the passenger seat.
- the processing unit is designed to transmit the control parameter to the airbag control unit.
- the airbag control unit is designed to activate, deactivate or reactivate the passenger airbag depending on further parameters.
- Further parameters can be in particular an expected collision intensity, a collision intensity measured with the aid of sensors, e.g. acceleration sensors, and/or a collision speed between the vehicle and a collision object.
- the classification, the further classification or the overall classification are classified as classification result, first classification result, second classification result, further classification result and/or overall classification result: "empty passenger seat”, “empty child seat on the passenger seat”, “empty baby seat on the passenger seat”, “child in a forward-facing child seat on the passenger seat”, “child in a rear-facing baby seat on the passenger seat”, “child in a forward-facing baby seat on the passenger seat” and “adult in the passenger seat” (at least 5 percentile woman and above).
- the following are classified as sub-classification result: classifies a "person up to 1 year old", a "person 1 to 3 years old", a "person 3 to 6 years old” and/or a "person 6 to 10 years old".
- the processing unit preferably determines the control parameter depending on the classification result and the subclassification result.
- the processing unit carries out the classification and/or the second classification and/or the sub-classification based on the image data using a human body pose estimation method, a pattern recognition method and/or a machine learning method.
- a human body pose estimation method dimensions of limbs can be determined in particular from a 2-dimensional image, which can then be used for object recognition, in particular for determining the age of a child.
- the airbag control unit is designed to deactivate the airbag depending on the control parameter dependent on the classification result and/or the sub-classification result and that the airbag control unit is designed to reactivate the airbag depending on the control parameter and depending on the sensor signals from at least one airbag triggering sensor unit. This makes it easy to reactivate the passenger airbag, particularly in the event of serious crashes.
- the airbag control unit when detecting a collision, at a collision speed with a collision object of greater than or equal to a preset speed threshold value or at a medium or high expected severity of an expected or occurred collision determined by the airbag control unit on the basis of sensor signals and a control parameter based on a classification of a child in a forward-facing child seat and/or a subclassification of a 6 to 10-year-old child, the airbag is reactivated. A collision with an impact speed of 56 km/h is considered to be severe.
- the camera is an interior camera of the vehicle, wherein the field of view of the camera in particular has a detection angle in the range of 100° to 150°, wherein the camera is preferably a monocular camera and/or an RGB camera and/or an RGB-IR camera.
- the images recorded with the camera can be used in combination with a sensor unit integrated into the passenger seat, in particular the sensor mat, to classify an object on the passenger seat.
- the triggering logic of an airbag control unit for deactivating the passenger airbag or for reactivating the passenger airbag depends on the severity of a crash.

- FIG 1 shows a perspective schematic representation of a cockpit 100 of a vehicle 102.
- a vehicle driver 104 sits on a driver's seat 106 of the vehicle 102.
- a display 108 for displaying information when the passenger airbag 146 of the vehicle 102 is deactivated is arranged, for example, in the area of a center console 110 of the cockpit 100.
- the cockpit 100 also includes a central information display (CID) 112, a head-up display 114 and a graphic instrument cluster 116, which are arranged in a dashboard 118 of the vehicle 102.
- the dashboard 118 also includes air outlet nozzles 120 of an air conditioning system of the vehicle 102.
- air outlet nozzles 120 are shown, for example, in the area of the center console 110 and on a passenger side.

- a camera 134 is arranged in the upper area of a windshield 132 of the vehicle 102.
- the camera 134 is arranged and aligned in such a way that it captures images 200, 300 with an image of an area of the interior of the vehicle 102 that includes at least a part of the passenger seat 202.
- the field of view of the camera 134 is directed towards the driver's seat 106 and a passenger seat 202 of the Vehicle 102.
- Exemplary images 200, 300 of the camera 134 are shown in Figures 2 and 3.
- the camera 134 is designed in particular to capture a plurality of images following one another in time, to generate image data corresponding to the images 200, 300 and to transmit these to a control unit 136.
- the camera 134 has a field of view of 120 degrees. In other embodiments, the camera 134 can also have a field of view in the range of 150 degrees or more.
- the control unit 136 has data outputs 138 and data inputs 140, which are used to connect to other units of the vehicle 102, for example to other sensors, input and output units and control units of assistance systems.
- the control unit 136 is connected to an airbag control unit 142, which is designed to trigger the airbags of the vehicle 102 in accident situations, i.e. in the event of a crash, in particular to control the triggering of the passenger airbag 146.
- the control unit 136 further comprises a communication module 144 which is designed to establish a connection to a telecommunications network, in particular a mobile radio network.
- a sensor mat integrated in the passenger seat 202 detects the weight of an object located on the passenger seat 202.
- a sensor mat can be a capacitive or pressure-sensitive sensor mat.
- a possible object located on the passenger seat 202 is classified as "no object present or empty passenger seat”, “empty child seat on the passenger seat”, “empty baby seat on the passenger seat”, “child in a forward-facing child seat on the passenger seat”, “child in a rear-facing baby seat on the passenger seat”, “child in a forward-facing baby seat on the passenger seat” and "adult person on the passenger seat”.
- the control unit 136 determines a control parameter depending on the classification result and the sub-classification result, which is transmitted to the airbag control unit 142. It is advantageous if the sensor mat integrated in the passenger seat 202 determines the weight of the child 302 including the child seat 310.
- the weight of the empty child seat 310 was determined with the help of the sensor mat and stored in the control unit 136.
- the weight of the child 302 can thus be determined relatively accurately and used to determine the Age of the child 302 can be used.

- the camera 134 captures an image with a depiction of an area of the vehicle interior comprising at least part of the passenger seat 202 and generates image data corresponding to the image, which the control unit 136 processes.
- the control unit 136 carries out a second classification of an object located on the passenger seat 202 based on the image data and determines a second classification result.
- the control unit 136 adjusts at least one threshold value used for the first classification in such a way that the first classification result matches the second classification result after the adjustment. This permanently improves the first classification so that the first classification is carried out during or before each journey and the second classification only needs to be carried out at longer intervals.
- the second classification can also be carried out during each journey or before each journey.
- the control unit 136 determines the control parameter for controlling the airbag control unit 142 based on an adjusted first classification result determined after the adjustment during classification and transmits it to the airbag control unit 142.
- at least one camera 134 of the vehicle 102 is provided, which captures at least one image with an image of an area of the vehicle interior comprising at least part of the passenger seat 202 and generates image data corresponding to the image, which the control unit 136 then processes. Based on the image data, the control unit 136 carries out a classification of an object located on the passenger seat 202 and determines a classification result.
- control unit 136 determines a control parameter for an airbag control unit 142 for triggering the passenger airbag 146. This makes an exact classification and also a correct subclassification of the object possible in a simple and reliable manner. Incorrect classifications are avoided.
- a sensor mat integrated into a passenger seat 202 can determine at least one measured value of the weight of an object located on the passenger seat 202.
- the control unit 136 processes the measured value transmitted from the sensor mat to the control unit 136 and, based on the measured value and at least one threshold value stored in the control unit 136, classifies the object in order to determine a further classification result.
- the control unit 136 determines an overall classification result based on the determined classification results of the classification and the further classification.
