Method for switching points in a digital control system for track-guided toy vehicles

1. A process for operating a digital control system for track-guided toy vehicles, having at least two tracks for toy vehicles on a car race track with at least two guide slots as the tracks, including at least one switch where in the switched condition, optionally connects two tracks to each other in such a manner that a toy vehicle, when passing over the switch, changes from one track to another track, and which, in the unswitched condition, continues to guide the toy vehicle on the same track without changing tracks, where, in each case a switching command issued for a certain toy vehicle to switch a switch which the certain toy vehicle will be the next to cross is transmitted in the switched condition in the digital control system together with a digital address of the certain toy vehicle for which the switching command is valid; including at least one toy vehicle, for which a switching command is transmitted, transmits an identification which represents the digital address or another encoding of said at least one toy vehicle in the digital control system; that each switch receives an identification transmitted by the toy vehicle which is approaching this switch and compares it to the digital address of one or more transmitted switching commands and that the switch changes into the switched condition if the digital address in the identification received from the toy vehicle is identical to a digital address for which a switching command is transmitted in the digital control system.

2. The process of claim 1 wherein a switch which is in the switched condition again receives the identification of vehicles after the switch in the direction of travel and evaluates the identification and changes back from the switched condition into the unswitched condition if the identification received from the toy vehicle contains the digital address for which the switch previously changed into the switched condition.

3. The process of claim 2 including having the identification of the toy vehicle transmitted optically to the switch.

4. The process of claim 1 including for each switching command transmitted in the digital control system, the digital address transmitted with this switching command is stored in each switch.

5. The process of claim 4 including deleting the stored digital address as soon as the associated switch command is no longer transmitted and/or as soon as a predetermined period of time has passed.

6. The process of claim 1 including having the identification of the toy vehicle transmitted optically to the switch.

7. The process of claim 6 wherein the optical transmission is accomplished through an infrared diode in the toy vehicle to at least one infrared detector, especially a phototransistor in the switch.

8. The process of claim 1 including having the identification of each toy vehicle transmitted continuously.

9. The process of claim 1 including having the identification of a vehicle transmitted only for a predetermined time when the vehicle passes a predetermined marking.

10. The process of claim 9 wherein the marking is a segment of track in which the power transmission to the toy vehicle is interrupted.

11. The process of claim 1 including having the identification of a toy vehicle transmitted only when and as long as a switching command is transmitted for this vehicle.

12. A digital control system for track-guided toy vehicles with at least two tracks for toy vehicles on a car race track with at least two guide slots as tracks, where at least one switch is provided which, in the switched condition optionally connects two tracks to each other in such a manner that a toy vehicle, when passing over the switch, changes from one track to another track, and which, in an unswitched condition, continues to guide the toy vehicle on the track without changing tracks, where at least one track has a digital decoder which is connected to a setting device for the switch and the digital control system including at least one switch in addition to the digital decoder having a first receiving unit which is connected to the digital decoder and arranged and constructed in such a manner that the first receiving unit receives an identification transmitted from a toy vehicle, which contains a digital address of the toy vehicle, and forwards it to the digital decoder of the switch before the toy vehicle passes over the switch.

13. The digital control system of claim 12 including having the first receiving unit constructed as a phototransistor.

14. The digital control system of claim 12 including the at least one switch, in addition to the digital decoder and the first receiving unit, having a second receiving unit which is connected to the digital decoder and is arranged and constructed in such a manner that this second receiving unit receives an identification transmitted by the toy vehicle and forwards it to the digital decoder of the switch, after the toy vehicle has passed over the switch.

15. The digital control system of claim 14 including having the second receiving unit constructed as a phototransistor.

16. The digital control system of claim 12 wherein at least one toy vehicle includes a transmitting unit to transmit an individual toy vehicle identification.

17. The digital control system of claim 16 including having the transmitting unit constructed as an infrared diode.

18. A switch for a digital control system for track-guided toy vehicles having at least two tracks for toy vehicles on a car race track with at least two guide slots as tracks, where the switch in the switched position optionally connects two tracks to each other in such a manner that a toy vehicle, when passing over the switch, changes from one track to another track, and, in the unswitched position, continues to guide the toy vehicle on the same track without changing tracks, where the switch includes a digital decoder which is connected to a setting device for the switch and the digital control system including the switch, in addition to the digital decoder, having a first receiving unit which is connected to the digital decoder as well as arranged and constructed in such a manner that the first receiving unit receives an individual vehicle identification transmitted by the toy vehicle, which contains a digital address of the toy vehicle, and forwards it to the digital decoder of the switch before the toy vehicle passes over the switch.

19. The switch of claim 18 including having the first receiving unit constructed as a phototransistor.

20. The switch of claim 18 wherein the switch in addition to the digital decoder and the first receiving unit includes a second receiving unit which is connected to the digital decoder as well as being arranged and constructed in such a manner that this second receiving unit receives an identification transmitted by the toy vehicle and forwards it to the digital decoder of the switch after the toy vehicle has passed over the switch.

21. The switch of claim 20 including having the second receiving unit constructed as a phototransistor.
