CA 2428695

A communication scheme is employed for transmitting control signals from a remote control (210) to a toy vehicle. The remote control includes control switches, an encoder and a transmitter (224) and the toy vehicle in accordance with received control signals. The encoder generates a continuous stream (102) of control signal packets (100) with each of the packets (100) including a predetermined number of biphase encoded bits. Each biphase encoded bit is of the same predetermined width with a 50 % duty cycle, including two transmit elements. For one binary state, both of the transmit elements are the same and for the other binary state both of the transmit elements are opposite. Each packet (100) includes a first predetermined number of flag bits (104), a second predetermined number of data bits (108) and at least one checksum bit (106).

L'invention concerne un schéma de communication mis en oeuvre pour transmettre des signaux de commande à un véhicule-jouet à partir d'une télécommande (210). La télécommande comprend des commutateurs de commande, un codeur et un émetteur et le véhicule-jouet conformément aux signaux de commande reçus. Le codeur génère un train continu (102) de paquets (100) de signaux de commande, chaque paquet (100) comprenant un nombre prédéterminé de bits codés biphasés. Chaque bit codé biphasé est de la même largeur prédéterminée avec un cycle de travail de 50 % et comprend deux éléments de transmission. Pour un état binaire, les deux éléments de transmission sont identiques et pour l'autre état binaire, les deux éléments de transmission sont opposés. Chaque paquet (100) comprend un premier nombre prédéterminé de bits indicateurs (104), un second nombre prédéterminé de bits d'information (108) et au moins un bit de somme de contrôle (106).
