Definitions

  • the invention relates to a method and a device for opening and closing a rotatably or tiltably mounted in a vehicle part, in particular a door, a Ausstellmens, a trunk lid, a hood or a folding roof, according to the preamble of the independent claims.
  • a drive is actuated by means of a control, which moves the flap between a Aufklapp position and a Zuklapp position, wherein the respective position of the flap is detected.
  • the electric motor is connected via a rotary joint with a Helbelmechanismus, which in turn is connected via a rotary joint with the flap.
  • the method according to the invention with the characterizing features of claim 1 has the advantage that obstacles in the immediate vicinity of the vehicle when opening a rotatable or tiltable mounted part detected in time and the part is stopped before hitting an obstacle.
  • the obstacle is detected completely independent of whether the part is operated by motor or manually.
  • an obstacle located between the part and the vehicle is registered, and the movements of the part are stopped or reversed if the part already touches the obstacle.
  • both a risk of injury by pinching body parts, as well as damage to the vehicle or this surrounding objects is prevented.
  • sensors are arranged on the outer and / or inner side of the movable part, obstacles are detected early regardless of the actuating mechanism of the part, so that the movements of the part can be stopped or reversed upon reaching a minimum distance to the obstacle.
  • the sensor signals are thereby fed to a control unit which either controls the motor movements of the part or which influences the manual movements of the part.
  • ultrasound sensors or sensors are used for the method which emit and receive electromagnetic waves (RADAR).
  • transmitter and receiver can advantageously be combined in one component.
  • These sensors can detect an obstacle contactlessly, whereby the part can be stopped before abutting the obstacle.
  • the sensors are arranged so that their radiation fans cover the entire inner and / or outer surface of the part. If the sensors are moved along with the part, the sensitivity of the obstacle detection remains equally good in every position of the part. Covering the entire surface of the part ensures that every obstacle in the movement area of the part is detected in good time.
  • the sensors are not fastened to the body according to the invention, their radiation cone covers the entire adjustment path of the part.
  • a reference signal of the undisturbed motion sequence of the part is stored in the control unit. If the detected sensor signal deviates from the stored reference signal, this deviation is detected as an obstacle and the movement of the part is stopped or reversed.
  • This method can also be used to safely monitor the movement of moving parts with a complex or changing structure (folding roof).
  • the sensors can remain active even when the vehicle is parked for an arbitrarily adjustable period of time. For example, a sensor mounted on the inside of a hood can register the entry of animals, especially martens, into the engine compartment and trigger a warning signal to drive them out.
  • the operational readiness of the sensor can be selected according to the cooling time of the engine.
  • Another advantage of the operational sensors with parked vehicle is the realization of a burglary protection.
  • the sensors both as a motion detector in the interior of the vehicle as well as in the immediate vicinity of the vehicle register an unauthorized intrusion into the vehicle and trigger an alarm signal.

  • a parameter for the detection of an obstacle which is characteristic of the adjusting force applied by the motor.
  • An obstacle is detected particularly reliably when the non-contact sensors are combined with the detection of the parameter representing the adjusting force of the part.
  • the obstacle in a first stage, the obstacle is already detected before touching it by means of the sensors and, if the obstacle was not detected by them or the part was not stopped / reversed in time, in a second stage, the obstacle in contact with the part by means of the Detecting force representative parameter detected.
  • the invention consists in subdividing the range of movement of the part into different danger areas.
  • an obstacle can be detected by means of sensors and immediately before full closure by means of the parameter representing the adjustment force when the part is wide open. This ensures a higher level of security against a risk of pinching.
  • the function of the detection by means of sensors can be monitored by the parameter representing the adjusting force of the part. It will primarily the sensor signal evaluated but also compared simultaneously with the result of the measurement of the adjusting force representing parameter. Likewise, areas in which obstacles are detected primarily with the parameters representing the adjustment force can be monitored by a comparison with the sensor signal. This also increases the reliability of obstacle detection.
  • a significant increase in comfort is the operation of the motorized moving part by remote control.
  • the reliable realization of obstacle detection while damage to the part / obstacle or jamming is prevented.
  • the obstacle detection function is preferably switched off.
  • the control unit gets, for example, from the triggering device of the airbag a signal, eg. B. to open a door with maximum force without consideration of obstacle detection. As a result, the exit or recovery of the occupants after an accident is much easier.
  • the sensors determine the distance to a potential obstacle in the movement region of the part in order to calculate therefrom an allowable opening / closing angle of the part. This can be done before the part is moved and updated during the motion process.
  • the calculated permissible opening / closing angle is compared with the determined by the position detection position of the part and stopped before reaching the allowable opening / closing angle.
  • the position detection is preferably carried out by means of the measurement of the rotational speed or another parameter representing the adjustment of the part. This method is particularly suitable for opening a door when getting off in a narrow parking space.
  • the inventive method is advantageously applied to devices for opening and closing doors, Ausstellppern, trunk lids, hoods and folding roofs on motor vehicles. This increases comfort while minimizing the risk of injury or damage.
  • ultrasound sensors are particularly favorable since they provide reliable reception signals, especially at short distances. Also for the radiation of the waves parallel to the surface of the part of this sensor with combined transmitter and receiver is particularly suitable.
  • RARDAR sensors which have been adequately tested by other applications, such as, for example, park pilot systems (short range RADAR). In this case, sources of interference that reduce the reliability of the detection are excluded with high security.
  • the part for example a vehicle door
  • the part is designed so that it can be bent, since this creates more space, for example, for getting in or out.
  • the more complex movement mechanism can also be reliably monitored by the sensors to avoid a collision with an obstacle.
  • On Folding roof can be stowed very compactly in this way when the vehicle is open.
  • the device has a locking mechanism or a braking device, for example, in the hinge area of the part, then, when an obstacle is detected, even if the part is moved manually, it can be stopped before the obstacle is touched.
  • the sensors send a signal to the control unit, which then activates, for example, a lock or an electromagnetic brake device. This can prevent a non-motorized part from hitting an obstacle.

  • the rotational speed of the adjusting motor 16 is continuously measured as the parameter representing the adjusting force of the part 10 and compared with a previously determined limit value. If the speed falls below this threshold value, as long as the part 10 is not yet completely closed, this is interpreted as an entrapment event of an obstacle 30. Then, a signal is sent to the control unit 28 which stops or reverses the variable displacement motor 16.
  • a position detection 40 is necessary, which detects the position of the part 10, for example by means of two offset arranged on the motor shaft of the adjusting motor 16 Hall sensors.

  • both detection methods for obstacle detection are active simultaneously.
  • an obstacle 30 is detected by means of the sensors 24 before the part 10 touches the obstacle 30. If the part 10 is stopped too late, or if an obstacle 30 is overlooked by the sensors 24, in a second step the obstacle 30 is detected by means of the rotational speed measurement (parameter representing the adjustment force).
  • This two-stage system is used when opening and closing part 10 and provides a high level of safety.
  • the function of the sensors 24 in the detection area 36 can additionally be monitored by measuring the rotational speed (parameters representing the adjusting force).
