Abstract
Abstract A model vehicle such as a model railway vehicle includes a control and evaluation device located in the model vehicle, and a plurality of drive devices such as electric motors for moving the vehicle and for operating other movable components on the vehicle. A definable address is associated with the model vehicle, for example by being stored in a memory device connected to the control and evaluation device. The control and evaluation device includes or is connected to a switching network that is operable to selectably connect one of the drive devices to a regulating device in response to control signals from a central control unit. The regulating device is connected to a power supply and is operable to regulate the power supplied to the selected drive device in response to control signals from the central control unit. The control unit sends an address as part of its control signals, and the vehicle responds to the control signals if it has an address matching that sent by the control unit. Thus, a plurality of drive devices on a single vehicle can be selectively operated based on a single address unique to that vehicle.
