Patent ID: 8366509

Claim:
A process for operating a digital control system for track-guided toy vehicles on a car race track, comprising: providing at least one digital decoder in each toy vehicle to be controlled; providing several operating devices each including at least one actuating element for controlling a toy vehicle assigned to the operating device, such that digitally encoded data packets are transmitted to the digital decoders, said data packets containing status information of the at least one actuating element of the operating device, and a digital address which creates the assignment between the operating device and the toy vehicle operated by the operating device; storing the digital address of the operating device to which a toy vehicle is assigned in the digital decoder; evaluating the data packets in the digital decoder, in a normal mode,and forwarding to the toy vehicle only data or control commands dependent upon such data packets that contain the same digital address that is stored in the digital decoder; detecting in at least one digital decoder of the digital control system, condition data of at least one actuating element in each case of all operating devices of the digital control system; and switching the digital decoder to a programming mode after disconnecting and reconnecting the at least one digital decoder from and to a power supply, the switching occurring at the time of disconnecting this digital decoder from the power supply when the condition data from the at least one actuating element of an associated operating device includes a first predetermined condition and, upon reconnecting to the power supply, the condition data of the at least one actuating element of this associated operating device includes a second predetermined condition which differs from the first predetermined condition.
