  • the flap of the motor vehicle in the context of the invention, in principle, any element that can be exposed to a motor vehicle body is covered, which in the closed state conceals an opening and releases it in the opened state. Consequentially fall under the concept of the flap of the motor vehicle according to the invention, first of all, the one or all side doors of the motor vehicle.
  • the flap can basically also be a sliding door. Also include the term of the flap, a tailgate or a fuel filler flap
  • these entire flaps have in common that they sweep in their adjustment movement both in the transition from the closed to the open state and vice versa areas in the vicinity of the vehicle body, which go beyond the outer skin of the closed body more or less pronounced. In these areas extending beyond the outer skin of the closed motor vehicle body, collisions with one or more obstacles may occur even when the motor vehicle is at a standstill.
  • static obstacles In the context of the invention not only static obstacles are detected, but also obstacles that move dynamically.

  • environment sensors are increasingly being used today and are typically coupled to a driver assistance system of the motor vehicle.
  • the entire outer region of the motor vehicle body is sensory detected, not only punctiform or radiating in a plane, but typically spatially. That is to say, with the aid of the environment sensor used according to the invention, a certain predetermined area of space outside the outer skin of the closed body of the relevant motor vehicle is sensory examined and recorded. This area of space may change dynamically in size, as is known for driver assistance systems.
  • the sensor or ambient sensor may be a sound sensor and, in particular, an ultrasonic sensor. Such sound sensors or ultrasonic sensors are often used as a distance sensor.
  • imaging sensors and in particular cameras are conceivable and are covered according to the invention.
  • magnetic sensors and in particular Hall sensors are Especially preferred.

Similarly, lidar: light detection and ranging is used, with the fundamental difference that lidar measurements are usually performed with electromagnetic light.
  • the invention uses an already installed or existing environmental sensor or several of these environmental sensors, which are regularly coupled to the driver assistance system of the motor vehicle and supply it with the data required for this purpose.
  • the data acquired by this one or more sensors or environment sensors now has an additional use in the context of the invention, namely for controlling the flap.

  • the data of the one or more environmental sensors are routinely available for detecting obstacles in the vicinity or in the area of the vehicle body. These data are now used according to the invention to determine and / or move the flap in the event of an imminent collision of the flap with an obstacle detected by the sensor.
  • the environment of the motor vehicle detected by the surroundings sensor is typically divided into several areas. As a rule, these areas are angle ranges which each originate from the vehicle and usually correspond to an associated sensor. Separate Positions within these angular ranges can now be specified, for example, in a polar coordinate system. Basically, the use of a Cartesian coordinate system is possible as well as combinations.

  • the flap sensor associated with the flap can now be determined by the control unit occupancy of one or more associated areas of the environment through the flap in this process.
  • the flap sensor is a rotation angle sensor which, for example in the case of a side door of a motor vehicle, detects the respective opening angle of the relevant side door in comparison to the motor vehicle body and reports it to the control unit. Then, the flap sensor is arranged, for example, in or on an associated hinge of the flap.
  • the control unit now evaluates the signals of the one or more environment sensors and optionally the flap sensor and / or signals of other sensors.
  • These other sensors may be one or more vehicle dynamics sensors, one or more door actuation sensors, etc.
  • the evaluation is carried out, for example, to determine whether at least one matching area in the environment of the motor vehicle is occupied or can be occupied both with the obstacle and with the flap. Because that means a threatening collision. In most cases it will be done so that the areas occupied by the flap and the obstacle concerned are examined for possible mutual rimpedement. As soon as the distance between the regions approaching, for example, falls below a minimum value, for example when only two or three regions between the respectively occupied regions are present as a gap, the control unit intervenes. The same applies if a comparison of the space curves of the obstacle and that of the flap results in a decreasing distance and a threatening collision.
  • the control unit can now ensure that the flap is determined by acting on the retaining element on the flap. So you will usually proceed when the flap is moved manually or by motor. Alternatively or additionally, a movement of the flap by means of a drive provided on the flap is possible. In this case, one will proceed regularly so that the drive is applied to the flap by the control unit so that the movement is carried out and made in the direction of increasing the distance to the obstacle. In this case, the control unit actively intervenes in the movement of the flap. It is conceivable in this context that an example made opening movement of a side door of the motor vehicle or the motor vehicle side door is not only stopped, but opens into a counter-movement to close the relevant motor vehicle side door. Such a procedure is recommended, inter alia, in the event that the motor vehicle is parked on a sidewalk or a bicycle path and approaching a cyclist or pedestrian.
  • the control unit can additionally evaluate signals of one or more driving dynamics sensors.

  • the holding element on the flap is deactivated with the aid of the control unit by evaluating a corresponding signal. Only when the door actuation sensor in question is not (more) acted upon, this is implemented by the control unit to the effect that the holding element again active is.
  • the invention is also a method for opening a flap of a motor vehicle, which is explained in more detail in claim 10.
  • a device and an associated method for opening / closing a flap of a motor vehicle are presented, with whose help not only a safe opening or closing the respective motor vehicle door is possible, but collisions with any obstacles are reliably avoided.
  • the invention takes into account not only static obstacles, but also those with dynamic character, such as passing cars, cyclists but also pedestrians, etc.
  • the device works with one or more environmental sensors. With the help of these environment sensors, the entire environment of the motor vehicle can be detected and examined to see whether one or more areas of the environment are occupied by an obstacle. Even a change in the occupancy of a dynamically moving obstacle can be easily detected in this way. Likewise, a space curve completed by the obstacle. Now, if the occupancy of the one or more areas of the environment by the obstacle are known and are available in the control unit, countermeasures can be taken by the control unit to prevent any collisions with the flap when opening or closing. In fact, in the control unit not only the occupancy of one or more areas by the obstacle is known, but also the occupancy of individual or several areas by the flap during the opening process as well as during the closing process.
  • the control unit has the data of the space curves of the obstacle and the flap. Overall, this data can be extrapolated into the future in order to depict future scenarios as well as imminent collisions. If the adjustment of these movement states causes the areas occupied by the obstacle and the flap to approach each other too much (the distance lies below a critical threshold of required areas between the respectively occupied areas), then the control unit ensures, for example: that the flap is fixed by means of the retaining element. Alternatively or additionally, however, the flap can also be actively moved by means of the drive provided on the flap. In this case, one will specify the movement of the drive by the control unit so that the flap is as it were moved away from the obstacle.
  • the invention advantageously uses the today typically provided in a motor vehicle environment sensors that interact with one or more driving assistance systems while driving.
  • the data of the one or more surrounding sensors are evaluated with regard to detected obstacles in addition to the effect that collisions with a flap during opening / closing in relation to the motor vehicle body are prevented.
