    Toll collection device of a satellite toll system
    description
    The invention relates to a toll collection device of a satellite-based toll collection system, which is designed as a mobile device and can be fastened in a motor vehicle and comprises a controller. Furthermore, the invention relates to a method for setting up a toll collection device in a motor vehicle.
    A toll collection device, also called "On Board Unit". (OBU) is used to collect tolls within a satellites-based toll collection system. Each chargeable vehicle is equipped with such a device. The toll collection device is used to position the vehicle by means of a Global Navigation Satellite System (GPS), such as GPS. In addition, the toll collection device is set up for communication with centralized or decentralized toll system devices, for example by means of mobile radio devices and / or Dedicated Short Range Communication (DSRC). The determination of tolls takes place by means of known methods.
    To ensure optimum operation of the toll collection device, the location of the toll collection device in a motor vehicle is important. For this purpose, according to the prior art in assembly instructions, it is stated how the toll collection device is to be fastened, for example, to the inside of a windshield of the motor vehicle. A case of the toll collection device usually provides clues to align the toll collection device.
    A corresponding specification, for example, that a lower edge of the housing should be parallel to the lower edge of the front wheel of the motor vehicle. Such requirements are in the practical use of mobile
    Toll collection devices often disregarded, which leads to a wrong installation position. As a result, the function of the toll collection device is impaired.
    The invention has for its object to provide an improvement over the prior art for a data acquisition device of the type mentioned.
    According to the invention, this object is achieved by a data collection device according to claim 1 and a method according to claim 8. Improvements can be found in dependent claims.
    In this case, the toll collection device comprises a 3D acceleration sensor arranged to detect the ground acceleration, wherein the 3D acceleration sensor is connected to the controller for transmitting data, wherein the controller is adapted to generate from the data of the 3D acceleration sensor an output signal representing the attitude the toll detecting device is characterized with respect to the direction of ground acceleration, and wherein the controller is connected to an output unit for displaying a preferred position of the toll detecting device. The data of the 3D acceleration sensor incorporated in the computer is thus used to align the toll collection device with the mounting in the vehicle. In this case, the 3D acceleration sensor can also be used for other purposes, for example for a more accurate position determination of the motor vehicle in the road network.
    In an advantageous embodiment, the preferred location of the toll collection device is determined by the position of an antenna installed in the toll collection device. In this way, it is ensured that the user is displayed when the antenna is in an unfavorable position for receiving satellite signals.
    The antenna is preferably a DSRC antenna. Their situation is critical with respect to the receiving or. Broadcast quality. Conveniently, the antenna is a circularly polarized patch antenna.
    An advanced aspect of the invention provides that the preferred location of the toll collection device is also determined by the position of another antenna incorporated in the toll collection device. This is, for example, a GSNN antenna arranged in addition to anDSRC antenna. The alignment of the toll collection device is then based on the location of both antennas mounted in matched positions within the toll collection device.
    Furthermore, it is advantageous if the toll collection device comprises a fastening element, by means of which the toll collection device can be detachably fastened to a windscreen of the motor vehicle. In such a traffic detection apparatus intended for mobile use in various automobiles, the display of the preferred attitude proves to be particularly useful. The correct attachment to the windscreen is then quickly and easily carried out. In this case, advantageously, the fastening element is designed as a suction cup. This ensures a safe and easy releasable attachment of the toll collection device to the windscreen. Alternatively, a releasable adhesive bond or other releasable connections such as hook-and-loop fasteners can be used.
    A further improvement envisages that an orthogonal coordinate system fixedly connected to the data acquisition device is fixed and that the 3D acceleration sensor transmits to the controller data relating to the acceleration due to gravity of this coordinate system. In this way, a simple determination of the location of the toll collection device is given.
    In this case, it is favorable if an axis of the orthogonal coordinate system is oriented orthogonally to the direction of the ground acceleration in the case of a preferred position of the sound detection device.
    The method according to the invention for setting up the aforementioned toll collection device provides that position data of the toll collection device with respect to the direction of the gravitational acceleration are transmitted to the controller by means of the 3D acceleration sensor and that an output signal is output by means of the output unit, by means of which the position of the toll collection device can be recognized with respect to the direction of the ground acceleration. Then, the output signal indicates to a user whether the toll collection device is in a preferred attitude position with respect to the direction of the earth acceleration.
    In this case, it is advantageous if an axis of the orthogonal coordinate system fixedly connected to the data acquisition device is given a horizontal axis in the case of a preferred position of the data acquisition device, whereby a component of the gravitational acceleration in the direction of this axis is determined by means of the 3D acceleration sensor and by means of the output unit a change in this acceleration component due to a change in position of the toll collection device. The degree of deviation of the positional position of the toll collection device from the preferred position is particularly easy to detect in this way.
    In an alternative method, too, an axis of the orthogonal coordinate system fixedly connected to the toll-detecting device at a preferred position of the
    Mauterfassungsgeräts specified as a horizontal axis. In addition, a vector aligned parallel to this axis is predetermined, whereby a component of this vector in the direction of gravitational acceleration is determined by means of the 3D acceleration sensor, and a change of this vector component due to a position change of the toll detecting device is indicated by means of the output unit.
    The invention will now be described by way of example with reference to the accompanying drawings. Shown schematically:
    Fig. 1 toll collection device in a preferred position
    Fig. 2 toll collection device in a wrong position
    The toll collection device 1 is detachably attached to the inside of a windshield 2 of a motor vehicle, for example with suction cups. It comprises a 3D acceleration sensor 3, a GNSS antenna 6, a controller 4 and an output unit 5, which are arranged within a common housing.
    The 3D acceleration sensor 3 is advantageously oriented so that a first axis x of an associated orthogonal coordinate system is directed upwards along the windshield 2 when the toll collection system 1 is in a preferred position. A second axis y then runs orthogonal to the direction of gravitational acceleration g. The second axis y of a correctly mounted toll collection device 1 thus extends horizontally, transversely to the direction of travel of the motor vehicle.
    In general, the preferred attitude position depends on the orientation of the GNSS antenna. This extends in the illustrated example in the direction of the second axis y.
    As soon as the toll collection device 1 is swung out of its preferred position, the position of the coordinate system fixedly connected to the toll collection device 1, which is associated with the 3D acceleration sensor 3, also changes.
    According to the invention, the toll collection device 1 indicates to a user whether the toll collection device 1 is in a preferred position with respect to the direction of gravitational acceleration g. This is used to set up the toll collection device 1 in the stationary vehicle.
    As soon as the toll collection device 1 is located on the windscreen 2 of the stationary motor vehicle, only the acceleration due to gravity is detected by means of 3D acceleration sensor 3.
    The data output from the 3D acceleration sensor 3 indicates the detected gravitational acceleration g with respect to the associated coordinate system. These data are fed to the controller 4 and are converted into a suitable output signal.
    Preferably, the toll collection device 1 includes an input device to place the toll collection device 1 in its own mounting mode. Then, for example, an audible output signal sounds until the toll collection device 1 is in the preferred position. Or the output signal will sound for a limited time as soon as the toll collection device 1 is in the preferred position.
    Similarly, an optical output signal may be used to indicate the location of the toll collection device 1. For example, an LED will illuminate red until the toll collection device 1 is in the preferred position. The correct position can then be displayed, for example, by means of a green LED.
    As long as the 3D acceleration sensor 3 detects acceleration in the direction of the second axis y, the data acquisition device 1 is not in the preferred position. Namely, the second axis y is not horizontal and the detected gravitational acceleration g has a component gy in the direction of the second axis y.
    In a preferred embodiment, the output unit 5an shows to what extent the current position of the sound detection device 1 deviates from the preferred position.
    For this purpose, for example, the acceleration due to gravity g in the direction of the second axis y is converted by the controller 4 into a corresponding output value and displayed by means of the output unit 5.
    In another embodiment, a vector v, which is parallel to the second axis y, is determined to determine a corresponding output signal. While a user sets up the position of the toll detecting device 1, by means of the 3D acceleration sensor 3, a component vg of this vector v is detected in the direction of acceleration of gravity g and reported to the controller 4. The controller 4 converts these data into values which are displayed by the output unit 5. Only when the component vg disappears in the direction of the ground acceleration g, the sound detection device 1 is in the preferred position. The display unit then displays, for example, the value zero.
    An alternative provides that by means of 3D acceleration sensor 3 directly an inclination angle of a coordinate axis with respect to the direction of the ground acceleration g is detected. A corresponding data signal is processed by controller 4 to a display value displayed by output unit 5.
    Advantageously, for the preferred location, a range is set within which proper functioning of the toll collection device 1 is ensured. Concretely, upper and lower limits are specified for the individual position data.
    In a further development, the inclination of the windshield 2 of the motor vehicle can also be evaluated by means of a 3D acceleration sensor. The user may then be presented with a limited function of the toll collection device 1 if the motor vehicle has a too steep or too flat front disc 2. At this time, a third axis z of the coordinate system with respect to the direction of the ground acceleration g is evaluated.
