Abstract:
Data obtained and preferably stored or buffered by the positioning system for racing cars according to an older, separate application PCT/EP00/10518 is used to support computer-based simulation games, The reference data obtained in such a way forms marginal conditions for the computer simulation game. The use of the positioning system, or the data obtained thereby, opens up the possibility of providing such simulation games with an as yet unachieved realistic touch. The real-time axis of the racing course, for example, or the real driving condition data and operating data pertained to the racing cars during the real finished or ongoing race are entered as marginal conditions for the simulation game. Tis data can be made compatible with the simulation immediately by means of appropriate interface software.

Description:
DESCRIPTION  
         [0001]    The present invention Concerns a positioning system for racing vehicles, in particular for use with Formula One races, and in particular with reference to the use of data gathered by such a positioning system in the course of a race.  
           [0002]    Sports races with various race vehicles have been known and popular for centuries. Their popularity has often led to the development and use of special vehicles for the type of race, of racetrack improvements, driving techniques etc. There are always new developments that provide increased safety, information to the public and increased racing speed or the like.  
           [0003]    U.S. Pat. No. 5,731,788 shows a system and procedure to control the positioning and manage the positions and speeds of racing yachts that encompasses the strategic placement of GPS receivers and transmitters on a buoy and a committee boat marking the starting line for yacht races, as well as the radio and GPS receivers on the yacht, GPS and radio transmitter units are attached to a buoy at the starting line of the race and a committee boat and another GPS and radio transmitter unit receives GPS signals from positioning satellites and radio signals from the starting buoy and the committee boat. The information received by the racing yacht is processed in order to determine, the relative and absolute positions and speeds as well as the estimated arrival time back at the starting line of the race at the average current yacht speed for display on a user-friendly race control screen.  
           [0004]    Another example is U.S. Pat. No. 3,724,649 that shows a racecar monitoring system that represents a completely automated system to monitor a race or the like. Each vehicle carries a transponder that calculates when it passes a certain position event, for example the crossing of the starting/finishing line, the entry or exit from the box area etc., and that transmits the respective signal to a receiver on the side of the track next to the position event in a time-multiplex process with the transponders of all other vehicles. A main transmitter transmits a synchronization signal that is divisible time-wise to all vehicle transponders and each transponder is designed to transmit a position event signal only during a specified time segment of the synchronization signal. The receivers at the side of the racetrack feed into a central control unit that is also synchronized with the main transmitter and that records the appearance of the position events of each vehicle in real time. A clock and a computer are provided to be able to determine the race rank, the rotation speeds etc, from the recorded data. The system for recognizing a position event is based on the principle that an inductance carried in the vehicle crosses a changeable magnetic field, the polarity orientation of which defines the position of the respective event.  
           [0005]    Furthermore, U.S. Pat. No. 4,949,067 shows a race danger warning system that encompasses a transmitter activated by a track surveyor or other race official as well as a sufficient number of receiver units so that each racing vehicle has a receiver unit. The transmitter sends a coded signal that can be received anywhere along the racetrack depending on the status of a red, yellow or green flag. The receiver units that are self-contained and include a built-in power supply receive and decode the signal and subsequently switch on green, yellow or red lamps. The system essentially alerts the race participants to an imminent danger situation on the racetrack.  
           [0006]    In our own, previous patent application PCT/BP00/10158, whose content is included in the present application, a positioning system for racecars is proposed that offers an increased functionality, simpler control and increased safety compared with the current state of the art. Other advantages of the invention are explained in detail below.  
           [0007]    Important characteristics of this positioning system are indicated in claims  6  to  20 .  
           [0008]    In essence such a positioning system according to a first embodiment consists of a vehicle information device installed in a racecar, and which includes a positioning device for the collection and output of position data through which the position of the racing vehicle can be determined, and a transmitter that sends the position data to a control center. This ensures a cost-effective and reliable determination of the vehicle position. In particular it avoids the possibility of confusing the various racecars as each racecar determines and reports its own position data. In addition the transmitter can also be used to send further data to the control center.  
           [0009]    For an advantageous embodiment of the invention a plurality of such vehicle information devices is operated in combination with a computation unit that calculates the position of the various vehicles on the track from the position data with the help of stored racetrack data. Through the virtual display of the race course in the form of racetrack data the respective positions of the racecars can be calculated using the transmitted position data without the need to install position-calculating devices at all important points of the racetrack. It is even possible to determine when a vehicle exits the racetrack or is stalling on the track and to pinpoint its position precisely without additional effort.  
           [0010]    The track data may be reused if stored in a professional manner; however, in case the track changes they can also be updated either in part or in full as needed. Even the transfer of the track data to another positioning systems is feasible.  
           [0011]    Any professional knows that positioning data can be collected in a vehicle in many ways. For example the vehicle can be equipped with a GPS receiver (GPS “Global Positioning System,” a global, satellite-supported navigation system) or other satellite receiver, a localizing receiver or a gyrosensor. It is also possible to use a redundant combination of such receivers or sensors. If necessary the various racing vehicles can also be equipped with different positioning devices to collect the position data. In case a localizing receiver is used it is necessary to complete the positioning system with at least three localizing transmitters along the racetrack the positions of which are known exactly. By measuring the distance between the localizing transmitters and the respective localizing receiver the position of the latter can be determined  
           [0012]    As already mentioned above, the transmitter provided in the vehicle information device can also be used to transmit vehicle-operating data, for example vehicle speed, engine rotations and similar data, Such data are collected through respective sensors or from the electronic system of the vehicle and help in quickly recognizing a stall or other dangers the racecar might be in. In order to prevent an abuse of the positioning and operating data, the data can be transmitted partially or fully encoded in a known manner. Even for this advantageous characteristic of the invention it is not necessary to equip the various vehicle information devices or racecars in the same way.  
           [0013]    The positioning system preferably includes a control center that has the above-mentioned computation unit, a memory to store the track data of the racetrack and one or more receivers to receive the positioning and operating data sent by the various vehicle information devices. In such a case the system components that do not necessarily have to be separated in space can be designed as individual components, as partial groups or as an integrated total unit.  
           [0014]    It is also of advantage if the control center has a transmitter that can be used for sending safety data and if one or more racecars that are part of the positioning system have the respective receivers and display devices in order to, if need be, receive the safety data and display them. This would make it thus possible, for example when it is determined via the positioning system under this invention that a racecar has stalled, to emit and signal a warning analogous to the green, yellow and red flags used for Formula One races to the other racecars that are part of the positioning system,  
           [0015]    In particular the receivers mounted in the racecars can also be provided with an ID code that would allow the control center to selectively address the respective receiver. In this way it is possible to differentiate between the racecars that are part of the positioning system depending on the danger situation, For example racecars that will reach the danger spot only after a prolonged time would have a green signal while racecars that will pass the danger spot shortly would have a “red” signal. The other vehicles would have a “yellow” signal. Other professionally practiced differentiation methods, for example the time and frequency multiplex operation, may also be used here to make it possible to selectively address the various racecars.  
           [0016]    In order to circumvent the need of having all racecars take part in the positioning system or to guarantee further track safety, the track monitoring posts normally set up at race events may also be part of the positioning system by equipping one or more of them also with receivers and display units that receive and properly display the transmitted safety data. Again, by using an ID code or something similar, it is possible to selectively contact the respective track monitoring post possible. For security reasons the safety data can be fully or partially coded in a professional manner,  
           [0017]    Preferably the positioning system as per invention includes a representation device that gives a visual display of the actual positions of selected racecars on the racetrack via the track data and the computed vehicle positions. If necessary this task can be taken over by the computation unit so that no additional hardware is needed for the representation device. For example the computation unit could process the collected position information together with the track data Into a video signal that Is transmitted to the television stations transmitting the race. The representation device however may also include one or more large screens or video screens that present the attending public with a visual display of selected vehicle positions. This results in a system that, aside from the advantages related to safety, also has the special benefit that the spectators-irrespective of where they are-can be kept informed about the race situation on the entire track in real time, thereby substantially increasing the attractiveness of a visit to the racetrack.  
           [0018]    The representation unit can also include a data processing device that allows, among other things, a visual display of the actual positions of selected racecars along the racetrack on displaying data processing devices, which for example are networked via a fixed network or a radio connection with the data processing device for the purpose of data transmission. This would allow for example the virtual transmission of the race on the Internet. Also other race data captured by the positioning system per this invention, for example the respective ranking or the actual speed of selected racecars could be called up or displayed through such a data-processing device integrated into the positioning system and the respective networking on the displaying data-processing devices. The data-processing device is integrated into the positioning system in such a manner that the relevant race data contained in the positioning system can be prepared and processed by the data-processing device for the professional input into a data network in a way that an intended audio and/or visual presentation of the race or the desired race data on the respective displaying data-processing device is feasible. Moreover, the respective representations of a plurality of displaying data-processing devices can differ from one another. For example, a cell phone functioning as a displaying data-processing device could show only the respective ranking and the lead of selected racecars, while a computer networked via the Internet with a data-processing device could present a virtual display of the race on the screen, e.g. the actual positions of randomly selected racecars along the racetrack, Preferably the desired mode of representation or the information to be shown is selected by interactive input by the user of the displaying data-processing unit and the data-processing device.  
           [0019]    All or selected components of the positioning system as per this invention are preferably designed with a redundancy to guarantee the functionality of the positioning system even if one or more components fail This is above all true for the safety-related components of the positioning system, for example the computation unit.  
           [0020]    Alternatively the positioning system can be executed in a second embodiment in such a way that the respective vehicle information devices have only a transmitter for sending localizing signals instead of the positioning device and the transmitter. With the help of at least three spatially separated localizing receivers included in the system, position data can therefore be collected outside of the vehicle and transmitted to the control center where they are processed by the computation unit as described above. Since the localizing receivers can be connected to the control center e.g. via cables, there might be no need for a receiver at the control station. All other characteristics of the invention are the same as for the first embodiment.  
           [0021]    It is also possible to use this second embodiment only for selected racecars or that the two embodiments of the invention coexist among the participants in the race.  
           [0022]    The intent of this invention is to make use of the positioning system, which as shown above has special advantages, in a beneficial way for other applications,  
           [0023]    This task is accomplished by the characteristics of claim  1 . Beneficial variants are the subject of the sub-claims.  
           [0024]    According to the invention the data collected by the positioning system pursuant to the preceding proprietary application PCT/EP00/10518, and preferably put in storage or intermediate storage, are used to support computer-aided simulation games. The reference data therefore provide the framework for the computer simulation game. This use of the positioning system and the data collected thereby per this invention opens up the possibility to give such simulation games a degree of reality not achieved until now, for example by inputting the real time axis of the actual race or the real driving conditions and operating data of the racecars during the actually performed or ongoing race as framework for the simulation game, The data can be made compatible with the simulation via a suitable interface software without any problems.  
           [0025]    The data can be input into the simulation game as reference data in unprocessed or also in processed form, whereby a suitable interface or interface software again ensures compatibility of the data set with the simulation game. Within the framework of this data processing the time axis of the data can for example be extended so that the data can be used also quite well for inexperienced users.  
           [0026]    Simply by the fact that the position data taken in by the positioning system normally also include the altitude data of the race course, the simulation game can be made much more real to life. A further improvement can be achieved by allowing the operating data of the vehicles to flow into the simulation, making it possible for the first time in a simulation game to drive a course against other comparable vehicles in real time in such a way that the maneuverability of the vehicle is also taken into account.  
       
    
    
       [0027]    Examples for the embodiment of a positioning system whose data are used as reference data for a computer simulation are described in more detail with the use of drawings. These show:

         [0033]    [0033]FIG. 3C A racecar with a vehicle information device according to a second example of embodiment; 
     
    
       [0034]    [0034]FIG. 1 shows the rendition of a racetrack  2  through track data according to an advantageous embodiment example of a positioning system  1  as per the invention, It shows a plurality of vehicles  3 A,  3 B,  3 C and  3 ×located on a racetrack  2  that are part of the positioning system.  
         [0035]    In order to be able to calculate the position of one or more of the racecars  3  on racetrack  2 , the racetrack  2  is stored in positioning system  1  in the form of track data presented in such a way that a comparison of the track data with the position data received from the respective racecars  3  is possible. This comparison is carried out in a computation unit  9  of the positioning system, for example a digital EDP facility. Accordingly, the track data are stored preferably in a professional manner in a storage device of the computation unit  9 . It is also possible to store the track data in a storage device ( 10 ) connected with the computation unit  9  or to store the track data in a data memory that is read by a reading device taking the place of the storage device ( 10 ).  
         [0036]    According to the example of embodiment shown in FIG. 1, the racetrack  2  is rendered through orderly sequences of points  11  that are measured in a fixed system of coordinates  12  and that function as track data Connection the points  1  in sequence with straight-line segments defines therefore the inner and outer delimitation of the track  2 . In this way it is possible to render any desired two-dimensional track topology. Moreover, with the points  11  or the point sequences individual track segments and also the indicated direction can be defined or recognized. However, other ways to render the track that are known to professionals are of course also possible.  
         [0037]    In the example of embodiment shown in FIG. 1 the racecars  3  are located with the help of the system of coordinates  12 . However, since the comparison of coordinate data between different systems of coordinates requires only a mathematical transformation, the position data of the respective racecars  3  can also be determined on the basis of other systems of coordinates. This could for example occur if some racecars are located via GPS receivers while the position data of other racecars  3 D are determined through localizing receivers of a locally installed localizing system  23 .  
         [0038]    The figure assumes and indicates that the racecars  3  are moving counterclockwise on racetrack  2 . If it is also assumed that the racecar  3 X represents a stalled vehicle then racecar  3 A is very close to the danger spot. The racecar  3 B still has a safe distance to the immediate danger zone while according to the rendition there is no immediate danger for racecar  3 C. A stalled racecar  3  can be recognized by the fact that its position basically does not change anymore. By identifying the affected track segment and the respective positions of the remaining racecars  3 A,  3 B,  3 C participating in the positioning system  1 , the respective individual danger level for the remaining vehicles  3 A,  3 B,  3 C can be determined.  
         [0039]    The FIGS. 2A and 2B show several characteristics of a positioning system  1  according to an advantageous, example of embodiment following the first or second embodiment of the invention. Shown is a racetrack  2  on which are several racecars  3  participating in the positioning system  1  as well as two GPS satellites  24 . Along the racetrack  2  there are several track monitoring posts  22 , a spectator stand  20  and a large video screen  21 , with the former and latter being part of the positioning system  1  of the example. In the figures the positioning system  1  also includes a control center  7 , a transmitter-receiver facility  8  and a computation unit  9 . In FIG. 2B the positioning system  1  also includes three localizing receivers  23 .  
         [0040]    In FIG. 2A according to the first example of embodiment of the invention the racecar  3 D has a GPS receiver as positioning device  5  that receives radio signals from GPS satellites  24 . From these signals the GPS receiver or another suitable positioning device in racecar  3  gets position data through which the actual position of racecar  3  can be determined. The collected position data are transmitted via a transmitter  6  in racecar  3  to a control center  7  that has a receiving device assigned to transmitter  6 . Accordingly the respective transmitters  6  of the racecars  3  and the control station  7  of the preferred embodiment example shown in FIG. 2A form a star-shaped network, Together the positioning device  5  and the transmitter  6  in racecar  3  form a vehicle information device  4 .  
         [0041]    In FIG. 2B according to the second embodiment of the invention the position of the vehicle  3 D is determined through a localizing transmitter  6 B mounted in vehicle  3 D, through the at least three localizing receivers  23  set up close to racetrack  2  and the computation unit included in the control center  7 . The localizing transmitter  6 B emits localizing signals that are received by the localizing transmitters [TN: should probably be receivers], processed and retransmitted as position data to the control center  7 , where they serve to determine the position of vehicle  3 D in the computation unit. The position data can be transmitted in known fashion, for example per cable, from the localizing receivers  23  to the control center. This might obviate the need of a receiver  8  in the control center  7 . In the example of embodiment shown the receiver  8  serves to receive vehicle operating data or redundant position data from a data transmitter  6 A installed in the vehicle, which are preferable used for monitoring the position or the operating condition of the racecar  3 D.  
         [0042]    Per the invention each racecar  3  participating in the positioning system  1  has a vehicle information device  4 , which however may be designed according to different working principles. The steps described above for collecting position data and for calculating the position of a racecar  3  are also carried out mutatis mutandis for other vehicles.  
         [0043]    In a computation unit  9 , which includes a memory  10 , assigned to the control center  7 , the position of the racecar  3  along racetrack  2  is calculated from the position data with the help of the track data stored in memory  10 . The position calculated in this way indicates the ranking of racecar  3  among the racecars  3  participating in the positioning system  1  and also whether the racecar  3  has stalled, is driving dangerously slowly or has left the racetrack  2 .  
         [0044]    The FIGS. 2A and 2B for example indicate that the vehicle  3 ×participating in the positioning system has stalled. Based on the position information collected from computation unit  9  such a stall is determined preferably in control center  7  by the computation unit  9  or a device connected with the computation unit  9 . Subsequently a message is sent via the transmitter-receiver unit  8  to the racecars  3  and/or the track monitoring posts  22 . For security reasons the data per the invention are preferably sent by the transmitter-receiver unit  8  in coded form, Since the position of the stalled racecar  3 X is known, it is possible to send a targeted message to the track monitoring post  22 X closest to the racecar  3 X using an ID code or some other professionally practiced discriminating signal. It is also possible to send a message to racecars  3 C that differs from the message to racecars  3 B or  3 A. As mentioned above, depending on the danger level, vehicle  3 A can be sent a “red light” signal while the racecar  3 B receives a “yellow light” and the vehicles  3 C a “green light” signal, which are then displayed accordingly in the respective vehicles  3 , By the same token the danger could be communicated via display devices at the track margin, for example by a movable flag or a traffic light display.  
         [0045]    The FIGS. 2A and 2B show a large video screen  21  that is part of the positioning system, making a visual display of the actual vehicle positions of selected racecars  3  along racetrack  2  possible. The large video display  21  is fed by signals generated in the computation unit  9  or another representation device using the positions calculated in computation unit  9  and the stored track data as described above. Identical or similar data can also be fed to a television station or other transmission services such as an Internet provider for retransmission, The representation does not have to be limited to a display of the vehicle position but can include information about the respective vehicles  3  or other race or advertising information,  
         [0046]    The position information of the participating racecars  3  collected with the help of the positioning system  1  per the invention can also be used to point or train television or monitoring cameras along track  2  automatically at one or more selected vehicles  3 , It also could show automatically the picture of the camera that has the best view of a selected racecar  3 . A professional will easily recognize several other usable variations of this principle.  
         [0047]    The vehicles participating in the race require only a slight adaptation or upgrade. FIGS. 3A, 3B and  3 C show various design examples of the two embodiments for a racecar  3  equipped per the invention. Per the invention the vehicles  3  have an antenna  30  and a vehicle information device  4 , which are mounted in or on the vehicle in a professionally acceptable manner. The latter is indicated in FIG. 3B with broken lines.  
         [0048]    [0048]FIG. 3A shows a racecar with a stripped-down vehicle information device  4  according to the first embodiment of the invention in which the vehicle information device  4  includes only the essential components. As such the vehicle information device  4  has only a positioning device  5  and a transmitter  6 .  
         [0049]    In the shown embodiment example a GPS receiver  5  functions as a positioning device  5  and a data transmitter  6 A plays the role of the transmitter  6 . GPS radio signals are transmitted by a GPS satellite  24  to the GPS receiver via the antenna  30 , where they are processed into position data. The position data are processed in the data transmitter  6 A and relayed to the antenna  30  from where they are sent to a receiver  8  in the control center  7 . Professionals know that the assignment of tasks to the components  5 ,  6  included in the vehicle information device  4  can, if necessary, also be structured differently, As mentioned above, per the invention other positioning devices  5  and transmitters  6  can also be used.  
         [0050]    [0050]FIG. 3B shows a racecar with a stripped-down vehicle information device  4  according to the second embodiment of the invention in which the vehicle information device  4  includes only the essential components. As such the vehicle information device  4  has only a localizing transmitter  6 B that sends localizing signals via the antenna  30  to the respective localizing receivers  23  where they are analyzed as described above.  
         [0051]    Per the invention, the respective vehicle information devices  4  of the vehicles  3  participating in the positioning system can be connected to or even include one or more other devices  33 - 39  that transmit vehicle operating data or redundant position data to the transmitter  6  directly or via the vehicle information device  4  in order to relay these operating data or position data to the control center  7 . FIG. 3C shows a vehicle  3  equipped with many different additional devices. These additional devices  33 - 39  per the invention can be different for the respective vehicles  3 , The kind of additional devices for the respective racecars  3  depends, among other things, on the weight of the devices  33 - 39  as well as on their cost and need for space.  
         [0052]    The racecar  3  of the embodiment example shown in FIG. 3C corresponds both to the first and second embodiment of the invention as the shown vehicle information device  4  has a localizing transmitter  6  as well as a positioning device  5  and a transmitter  6 . This allows for a redundant positioning of the vehicle through the positioning system per the invention.  
         [0053]    The shown vehicle information device  4  uses an optional GPS receiver  5  as positioning device  5 . Via the antenna  30  or a separate antenna the GPS receiver  5  receives GPS signals  40  from GPS satellites  23  and derives from them GPS positioning signals that are relayed to the data transmitter  6  for retransmission to the control center  7 . Even though it is known that GPS data collected in this fashion are defective, no correction is necessarily needed per the invention since the defect is visited upon all vehicles  3  participating in the positioning system in the same way. If necessary a GPS receiver can be installed in the control center  7  whose GPS data are compared to the fixed, known position of the control center in order to calculate a correction vector for the GPS data derived from the vehicles  3 .  
         [0054]    For the redundant positioning of the racecar  3  the shown vehicle information device  4  has, among other things, additionally a localizing transmitter  6  that sends localizing signals to the localizing receivers  23  set up close to the racetrack  2  via the antenna  30  or a separate antenna. As described above, at that point position data for use in the control center  7  are derived from the localizing signals. If necessary the task of the localizing transmitter  6  is taken an by the data transmitter  6  or the two transmitters  6  are designed as an integral unit.  
         [0055]    The shown racecar  3  includes as additional equipment a engine rotation sensor  33 , a gear sensor  34 , a ground movement sensor  35 , a gyrosensor  36 , an induction loop sensor  37 , a wheel rotation sensor  38  and a position receiver  39 , The gyrosensor  36  measures the speed of the vehicle  3  via a piezoelectric element built into the gyrosensor  36  and provides position data based on the acceleration measurements. The engine rotation sensor  33  and the wheel rotation sensor  38  measure the rotational velocity of the motor or of one of the wheels in the usual manner and yield the respective data, preferably in the form of a pulse information or other digital data. The ground movement sensor  35  uses infrared, ultrasound or radar signals to measure the speed of the vehicle  3  and output it in the respective data form. The gear sensor determines the output speed of the gears and reports it also in data form. The passing of induction loops traditionally embedded in the race surface can be measured via the induction loop sensor  37  in order to collect position data. It is also possible to set up position transmitters with small apertures along the racetrack that send position signals  49  in the respective local area. The position signals  49  are received via the antenna  30  or a separate antenna by the position receiver  39  that processes the position signals  49  into position data and relays them to the data transmitter  6  for retransmission to the control center  7 .  
         [0056]    According to the shown embodiment example the data tom the respective sensors or devices  33 - 38  are relayed to the data transmitter  6  as data signals  43 - 48  for retransmission to the control center  7 . As indicated in FIG. 3C, if necessary selected data signals of the data signals  43 - 48  are relayed to the data transmitter  6  only after having been processed in the vehicle information device  4 . For security reasons the data per the invention are preferably sent to the transmitter  6  in encoded form.  
         [0057]    The shown vehicle information device  4  includes also a data receiver  31  that receives safety and data signals  42  preferably from the control center  7  via the antenna  30  or a separate antenna.  
         [0058]    The signals  42  are processed accordingly in data receiver  31  or in the vehicle information device  4  to implement, if necessary and as mentioned above, a warning display or other display via a display device, for example in the form of a cockpit indicator lamp  32  on the instrument panel.  
         [0059]    Per the invention the respective components of the vehicle information device  4  and/or sensors  33 - 38  are attached on board the vehicle  3  in a suitable place and are connected or networked with each other or with the transmitter  6  in a professionally accepted manner that preserves the intended functionality. Professionals know that the assignment of tasks between the components included in the positioning system per the invention can, if necessary, also be structured differently.  
         [0060]    Aside from determining the speeds, acceleration values, sense of rotation and velocity of movement the data collected by the physical sensors  33 - 38  are also compared as to whether there is a relationship between the calculated values in their mutual interplay that makes sense for an orderly forward movement of the vehicle  3 . If the output speed of the gears for example is disproportionately higher than the wheel speed one can immediately say that there is a differential defect, and if the wheel speed is disproportionately higher than the forward movement speed as measured above ground, one can immediately diagnose that the wheels are spinning. Together with the results of the accelerator sensor  36  and possibly the GPS receiver  5  this allows verifying a deviation from the admissible movement tolerance range not only in absolute values but also with redundant additional information.  
         [0061]    With the collected data of the GPS positioning device  5  and the physical sensors it is possible, with a high degree of assurance, to verify the correct or defective movement of the vehicle  3  on the racetrack  2  in the direction of the course, The data collected with the help of the described sensors or other professionally accepted sensors or devices can be used in the control center  7  to identify a possible stall, the position, speed and other data of a racecar  3  participating in the positioning system.  
         [0062]    In order to use the positioning system described above in an advantageous manner for other applications, the data that were collected through the positioning system described above and were preferably put in storage or interim storage can be used to support computer-aided simulation games. In this case the reference data form the framework conditions for the computer simulation. This use of the positioning system and the data collected with it opens up the possibility to give such simulation games a degree of reality not achieved until now, for example by inputting the real time axis of the actual race or the real driving conditions and operating data of the racecars during the actually performed or ongoing race as reference conditions for the simulation game. The data can be made compatible with the simulation via a suitable interface software without any problems.  
         [0063]    The data can be input into the simulation game as reference data in unprocessed or also in processed form, whereby a suitable interface or interface software again ensures compatibility of the data set with the simulation game. Within the framework of this data processing the time axis of the data can for example be extended so that the data can be used also quite well for inexperienced users.  
         [0064]    Simply by the fact that the position data taken in by the positioning system normally also include the altitude data of the race course, the simulation game can be made much more real to life. A further improvement can be achieved by allowing the operating data of the vehicles to flow into the simulation, making it possible for the first time in a simulation game to drive a course against other comparable vehicles in real time in such a way that the maneuverability of the vehicle is also taken into account.  
         [0065]    The professional has many devices at his disposal to collect, process, transmit and/or analyze the position and operating data within the framework of the claimed invention. For example by using a frequency or time multiplex signal or a corresponding ID code for the transmitted data, the data of the respective racecars  3  can be differentiated.  
         [0066]    Therefore the embodiment and application examples of the invention that are explained in the description serve only as an example for what the professional understands or could understand as equivalent in the respective context and that be could possibly use instead of one of the listed examples. Such equivalents are therefore as much part of the invention as the explicit, not all-comprehensive examples.
