Definitions

  • the invention relates to a device for controlling an occupant comfort system and / or occupant protection system in a motor vehicle, having a first sensor which detects a signal from which an occupancy of a vehicle seat by a vehicle occupant can be closed, and one coupled to the first sensor Control unit which activates the occupant comfort system and / or occupant protection system depending on the detected signal. Furthermore, the invention relates to a method for controlling an occupant comfort system and / or occupant protection system in a motor vehicle.
  • occupant comfort systems eg, belt conveyors or belt buckle conveyors
  • occupant comfort systems eg, belt conveyors or belt buckle conveyors
  • These bring the belt or the buckle in a bidding position, so that the application of the seat belt for the vehicle occupant is particularly easy and comfortable.
  • seat height adjusters are known which bring the vehicle seat in an elevated position, which facilitates boarding for the vehicle occupant, and then lower again.
  • These systems are usually triggered as soon as a signal of a door opening switch is detected by a control unit, ie already when opening the vehicle door or with a predetermined time delay after opening. This sometimes proves unfavorable in practice, in particular if a person opens the vehicle door but does not get into the vehicle immediately. In the worst case, then the occupant comfort system may even hinder the vehicle occupants when boarding, for example, by an extending out of the B-pillar of the vehicle arm, which brings the seat belt in a bidding position.
  • a device for controlling an occupant comfort system and / or occupant protection system of the aforementioned type in which the first sensor is arranged in the region of an inner handle of a vehicle door assigned to the vehicle seat. Touched now the vehicle occupant after boarding the inner handle of the vehicle door to close this, this is detected by the first sensor and passed a corresponding signal to the control unit, which then controls the occupant comfort system and / or occupant protection system, in particular activated and / or deactivated.
  • the occupant comfort system or occupant protection system is usually activated only after the vehicle occupant has actually entered the vehicle. In the case of an occupant protection system such as a gas bag module or a belt tensioner, of course, an activation is not to be understood as the triggering of the same, but the system is brought to a standby state or held therein.
  • the occupant comfort system and / or occupant protection system preferably has a drive which is activated by the control unit as soon as it receives the corresponding signal from the sensor.
  • the occupant comfort system and / or occupant protection system comprises a mechatronic, in particular reversible, system which is activated by the signal detected by the sensor and, for example, is deactivated again or returned to its initial state upon a further signal or after a predetermined period of time.
  • the occupant protection or occupant comfort system preferably comprises a belt feeder, a belt lock driver, an electric motor driven belt retractor and / or a seat height adjuster, which each serve to make it easier for the vehicle occupant to fasten their seatbelts.
  • the control unit activates, for example, the belt feeder and / or belt buckle bringers, which brings the belt or the buckle in a bidding position.
  • the vehicle seat is lowered from a raised position, which facilitates boarding, to a position favorable during travel.
  • a preferred embodiment of the invention provides a second sensor coupled to the control unit, which is arranged in the region of an outside handle of the vehicle door associated with the vehicle seat, in particular a passenger door, and the occupant comfort system and / or occupant protection system can also be activated depending on its signal.
  • the advantage of such an additional sensor in the region of the outer handle of the vehicle door is that the occupancy of the associated vehicle seat is detected even when the vehicle occupant does not close the door himself (ie from the inside), but this is done by another person who is outside the vehicle. This case occurs more often on the passenger side or possibly also in the rear seats; here it is more likely that the vehicle occupant is a person who needs help closing the door.
  • the first and / or second sensor may be a touch sensor, a pressure sensor, a proximity sensor and / or a capacitive sensor. Basically, any type of sensor is suitable here with which a touch of the door handle can be detected inside or outside.
  • the activation of the passenger comfort system and / or occupant protection system by the control unit takes place as a function of a signal of at least one sensor that is further from the first sensor.
  • a signal of at least one sensor that is further from the first sensor.
  • the at least one further sensor has a door opening switch, a seat covering mat and / or a buckle switch.
  • These sensors are common in modern vehicles, so existing systems can be used.
  • a further signal such as a buckle switch or a seat covering mat, it can be distinguished, for example, whether in the case of a signal from a mounted on the outside door handle sensor actually a person has got into the vehicle or only a piece of luggage was parked in the passenger seat.
  • a further signal such as a buckle switch or a seat covering mat
  • the senor in the inner handle part of the door inner handle unit which has a handle shell for a door opening lever or an armrest.
  • the sensor is designed so that it can detect touches both in the region of the door opening lever and in the region of the armrest. This makes it irrelevant whether the occupant closes the door over the provided on the armrest handle or the door opening lever, which are usually spatially separated from each other.
  • a second aspect of the invention provides a method for controlling an occupant comfort system and / or occupant protection system in a motor vehicle, in particular by means of a device as described in the previous sections.
  • the method comprises the following steps: First, a signal is detected by a sensor which is arranged in the region of an inner handle of a vehicle seat assigned to a vehicle seat, from which an occupancy of the vehicle seat by a vehicle occupant can be deduced. The signal is evaluated in a control unit coupled to the sensor, and the occupant comfort system and / or occupant protection system is activated by the control unit.
  • unwanted activation of the occupant comfort system or occupant protection system is largely avoided.
  • all further developments which are described with reference to the device according to the invention can also be used advantageously in the method according to the invention.
  • FIG. 1 is a schematic representation of a device according to the invention for controlling a passenger comfort system and / or occupant protection system;
  • FIG. 2 is a perspective view of the arrangement of a sensor of the device according to the invention in the interior of a vehicle;
  • FIG. 3 is a schematic representation of the arrangement of a sensor of the device according to the invention in the outer region of a vehicle.
  • FIG. 1 shows a device 10 for controlling an occupant comfort system 12 and an optional occupant protection system 13 in a motor vehicle, which has a control unit 14 and a first sensor 16 coupled to the control unit 14.
  • the sensor 16 detects whether a vehicle seat 18, here purely by way of example the driver's seat, is occupied by a vehicle occupant (see FIG. 2) and is arranged in the area Bi, B 2 of an inner handle of a vehicle door 20 (here corresponding to the driver's door).
  • the sensor 16 is part of the door inner handle unit 22, which comprises a handle shell 24 for a door opening lever 26 and an armrest 28.
  • the senor 16 may be arranged in one of the highlighted in Figure 2 areas BL B 2 , but preferably in both, since the vehicle door 20 could be closed by the occupant not only by pulling the handle of the armrest 28, but also by pulling the door opening lever 26 ,
  • the occupant comfort system 12 includes a mechatronic.es, reversible system such as a belt feeder, a belt buckle and / or a seat height adjuster.
  • a mechatronic.es, reversible system such as a belt feeder, a belt buckle and / or a seat height adjuster.
  • an occupant protection system 13 for example, a gas bag module or a belt tensioner, this activation is of course not to be understood as the activation of the same, but rather that the system is kept in a ready state or brought into it.
  • a second sensor 30 is provided which is arranged in the region B 3 of an outer handle 32 of the vehicle door 20 and is likewise coupled to the control unit 14.
  • the occupant comfort system 12 or occupant protection system 13 is likewise activated as a function of the signal from the second sensor 30.
  • This second sensor 30 in the exterior of the vehicle ensures that the occupant comfort system 12 (or occupant protection system 13) is activated even when the vehicle occupant does not close the vehicle door 20 from the inside, but rather by a person outside the vehicle.
  • the sensor 30 may be part of a keyless convenience entry system.
  • Both the first sensor 16 and the second sensor 30 is designed as a contact sensor, pressure sensor or proximity sensor, in particular it is a capacitive sensor.
  • the device 10 not only a passenger comfort system 12, but alternatively or additionally an occupant protection system 13 is to be controlled, it makes sense to activate the system by the control unit 14 in response to a signal of another sensor 34 and several other sensors allow.
  • the further sensor 34 may be e.g. to act a door opening switch, a seat occupancy mat and / or a buckle switch.
  • the method according to the invention for controlling the occupant comfort system 12 or the occupant protection system 13 provides in a first step, that a signal of the sensor 16 or the sensor 30 is detected, from which an occupancy of the vehicle seat 18 by a vehicle occupant can be closed, namely when the vehicle occupant touches the door opening lever 26 or the armrest 28 or if a person outside the vehicle the outside handle 32 touched. Subsequently, the signal is evaluated in the sensor 16 coupled to the control unit 14 and then the occupant comfort system 12 (or its drive 29) and / or the occupant protection system 13 activated by the control unit 14.
  • one or more further sensors 34 can detect further signals and transmit them to the control unit: opening or closing the vehicle door (door opening switch), occupancy of the vehicle seat (seat occupancy mat) and / or closing the seat belt (buckle switch) ,
