Definitions

  • the invention relates to seat occupancy recognition for a vehicle seat, in particular commercial vehicle seats, and to a method for recognising the occupancy of a seat.
  • the prior art discloses vehicle seats by means of which it can be recognised whether or not a vehicle seat is occupied.
  • Simple seats having seat occupancy recognition use sensor data, which can be used to recognise a weight on the vehicle seat and to draw conclusions on whether the seat is occupied by a person.
  • this method and the vehicle seat are not able to accurately recognise whether a person or any given object, e.g. a crate of beer, is positioned on the commercial vehicle seat.
  • a seat occupancy recognition device comprising at least one volume detection device having at least one first sensor provided and designed to detect a volume on the vehicle seat, and comprising at least one body function detection device having at least one second sensor provided and designed to detect body functions, in particular after a volume has been detected. More preferably, the seat occupancy recognition device comprises at least one body function measuring device for measuring the detected body functions.
  • a mass can also be recognised by means of the volume detection device, such that a seat occupancy is recognised when a mass is positioned on the vehicle seat.
  • outlines can also be recognised in order to recognise a seat occupancy in this manner.
  • the volume detection device of the seat occupancy recognition can therefore be designed as a volume-mass detection device, by means of which a volume and/or a mass can be determined.
  • a volume should be understood to mean at least a portion of the volume of a human body. By means of a volume detection device or a volume-mass detection device, it can therefore be recognised whether at least a portion of the volume of the human body is positioned on the vehicle seat.
  • sensors or sensor apparatuses that can simultaneously detect and register the occupancy of a seat and a body function, sensors or sensor apparatuses of this kind of course having to read and process the recorded signals properly.
  • At least one of an outline and a mass can additionally be detected by means of the first sensor of the volume detection device.
  • both the volume detection device, or volume-mass detection device, and the body function detection device comprise at least one sensor by means of which a volume or body function can be detected.
  • a sensor of this kind can be designed as a capacitive sensor, an inductive sensor, an electromagnetic sensor, a photoelectric sensor, an ultrasound sensor, or a combination thereof. Obviously, other types of sensor, not listed specifically here, are also conceivable.
  • the sensors are designed to allow contact-free detection. It is, of course, also conceivable for detection to be possible by the sensors coming into contact with the person or the like, although contact-free detection is advantageous since these sensors do not restrict or impair the person in their work.
  • the seat occupancy recognition device and, in particular, the sensors are integrated in the vehicle seat, and specifically such that they are arranged and particularly advantageously integrated in a seat part and/or in a backrest part.
  • the maximum of detection areas of at least the at least one first sensor being substantially in a range over the seat, in other words, in a range in which the person seated on the vehicle seat is expected to be found.
  • the detection areas can take various geometric shapes, for example round, oval, elliptical or even rectangular. As a result, adapting or shaping to fit the volume to be detected is conceivable. In particular, the detection areas can be adapted to the expected volume on the vehicle seat.
  • At least one sensor is arranged and, in particular, integrated in at least one armrest and/or in a display apparatus. Furthermore, in addition or alternatively, it is conceivable for at least one sensor to be arranged and, in particular, integrated in a cover of the vehicle seat, in particular a side cover.
  • At least one of cardiac function and pulmonary function can be recognised by means of the second sensor of the body function detection device.
  • gestures and/or movements typical of humans can be detected by means of the second sensor.
  • the seat occupancy recognition device comprises a body function recognition device for recognising body functions.
  • the recorded body functions can advantageously also be assigned to a person, and thus, the seat being occupied by an animal or at least one manipulated object can be ruled out.
  • the second sensor is designed and provided to record sensor data and to transmit said data to the body function measuring device, the measurement data being able to be compared with previously recorded measurement data by means of the body function measuring device in order to determine a health status.
  • the seat occupancy recognition device comprises a control device that is preferably connected to the volume detection device and the body function detection device at least for signalling.
  • a volume detection by means of the volume detection device can be initiated first, followed by a body function detection once the volume detection is complete.
  • the result of the volume detection can be used further by the control device. If the volume detection is negative, no body function detection is possible, for example, since the basic requirement for seat occupancy is not met.
  • control device initiates a body function detection.
  • the seat occupancy recognition is active as long as the vehicle, in particular the vehicle functions, are active or can be activated.
  • a vehicle can be deemed active if the engine has not yet been started but the ignition has already been activated, since activating the ignition already enables many vehicle functions.
  • the seat occupancy it is conceivable for the seat occupancy to be recognised continuously as long as the vehicle is active. Alternatively, it is also conceivable for the seat occupancy to be recognised after regular or irregular periods of time. In this context, the time periods can, of course, be selected and adjusted appropriately. Too long a period may result in the seat occupancy recognition being bypassed, which is, of course, undesirable due to safety issues.
  • the seat occupancy recognition is event-triggered, e.g. by the actuation of vehicle functions.
  • the volume detection device and the body function detection device are designed such that the corresponding volume and the corresponding body functions can be detected and measured in a contact-free manner.
  • detection or measurement by contact is also conceivable, but it is more convenient for vehicle drivers if contact-free detection or measurement is possible.
  • the first sensor and the second sensor are each selected from an optical, electrical, magnetic, electromagnetic, thermal, capacitive, acoustic or mechanical sensor.
  • the detection area of a capacitive sensor in particular, can take various geometric shapes.
  • a body function measuring device can be provided by means of which it can be recognised whether or not the recorded sensor data can be assigned to a person. It can thus be ruled out that, for example, an animal is positioned on the seat and the seat occupancy recognition is thus bypassed.
  • the seat occupancy recognition device can comprise a memory or a memory apparatus by means of which the recorded sensor data from the corresponding sensors can be stored. These stored values can then be retrieved again for further use, for example for displaying the change in heart rate or breathing rate, or to recognise particular health statuses by comparing said values with previously recorded sensor data.
  • the sensors used are either passive or active sensors, passive sensors being preferred since the seat occupancy recognition should be designed as simply as possible and should, if possible, not unnecessarily complicate the circuitry or construction of the vehicle seat.
