Abstract: A radio control system for a multi-controller, multi-vehicle, independently controlled toy vehicle system provides proportional steering and speed control without mutual interference. Each of a plurality of control sets repetitively transmits low-duty-cycle command bursts containing an identity code and steering and speed commands. The control sets transmit their command bursts asynchronously and, due to the low duty cycle of all transmissions, a high probability exists for non-inteference even when four or more control sets are simultaneously operated to control four or more toy vehicles. Each toy vehicle attempts to match any incoming command burst with a standard including an identity code unique to that vehicle. When a command burst is received which is correct in every respect, including the identity code, the steering and speed commands contained therein are stored and are executed until a new decodeable command burst is received.
