Ces consignee vent interpretees par le vehicule en fonction de sa position instantanee, I'utilisateur doit prendre en compte cette contrainte pour parvenir a piloter le jouet. Cette contrainte est peu acceptable pour un enfant. Tourner a droite est intuitif quand le vehicule s'eloigne du pilote, quand le vehicule revient These wind instructions interpreted by the vehicle as a function of its instantaneous position, the user must take this constraint into account in order to manage to control the toy. This constraint is hardly acceptable for a child. Turning right is intuitive when the vehicle moves away from the driver, when the vehicle comes back

Le spot genere par cette commande designe la zone que le vehicule motorise doit o atteindre. Le vehicule pour-quit le spot, I'enfant definit According to the invention, the child has a manual command in FIG. 1. This command emits collimated optical beams which projects a spot. The spot generated by this command indicates the area that the motorized vehicle must reach. The vehicle leaves the spot, the child defines

La cite electronique commande les moteurs: - pour avancer le vehicule si le spot s'eloigne dans l'axe du vehicule; o - pour tourner le vehicule dans la direction laterale This electronics receives information about the relative position of the spot. The electronic city controls the motors: - to advance the vehicle if the spot moves away from the center line of the vehicle; o - to turn the vehicle in the lateral direction

L'ambiance lumineuse artificielle est caracterisee par une frequence propre de 50 Hz ou 60 Hz, celle du reseau electrique domestique. L'ambiance lumineuse naturelle est quasi constante. Si les capteurs vent a reponse frequentielle rapide, o comme les diodes notamment, alors un filtrage peut etre effectue pour masquer l'effet de la lumiere ambiante et de la modulation 50 Hz ou 60 Hz et discriminer ainsi le spot. Aussi, une modulation de ['amplitude du faisceau du spot par exemple a 3 kHz est particulierement adaptee pour un filtrage en According to a version of the invention optimized for its sensitivity and the detection distance of the spot, the artificial and natural light environment is eliminated by electronic filtering. The artificial light environment is characterized by a natural frequency of 50 Hz or 60 Hz, that of the domestic electrical network. The natural light atmosphere is almost constant. If the wind sensors have fast frequency response, o like the diodes in particular, then filtering can be carried out to mask the effect of the ambient light and the 50 Hz or 60 Hz modulation and thus discriminate the spot. Also, a modulation of the amplitude of the spot beam for example at 3 kHz is particularly suitable for filtering in
reception a la meme frequence de 3 kHz. reception at the same frequency of 3 kHz.
Selon ['invention, un tel filtrage assure une grande sensibilite de la detection du spot dans le champ des capteurs, According to the invention, such a filtering ensures a high sensitivity of the detection of the spot in the field of the sensors,

o Dans une version encore plus evoluee seule la lumiere modulee a la frequence de modulation du spot est amplifiee, par exemple 3 Khz si telle est la frequence de modulation de la telecommande. La discrimination est realisee par un filtre accorde a cette frequence en 63, un filtre en structure cite 'de Rauch' dont la bande et les gains vent regles par R1 en relation avec C1, C2, R6 et enfin l'amplificateur operationnel U1. Dans une version encore plus evoluee, un deuxieme etage o de filtrage 64 rejecte la frequence de la lumiere artificielle, par exemple le 50 Hz, par un simple filtrage passe haut realise par R15 et C6; redresse les signaux a la seule frequence de 3 kHz, grace a la diode D2; et enfin en compare la tension Vs a un seuil Vref. De cette comparaison resulte un signal carre dit PWM proportionnel, signal traditionnel de commande d'un o In an even more advanced version, only the light modulated at the modulation frequency of the spot is amplified, for example 3 Khz if this is the modulation frequency of the remote control. The discrimination is carried out by a filter tuned to this frequency at 63, a filter in the cited 'Rauch' structure whose band and gains are adjusted by R1 in relation to C1, C2, R6 and finally the operational amplifier U1. In an even more advanced version, a second stage of filtering 64 rejects the frequency of artificial light, for example 50 Hz, by a simple high-pass filtering performed by R15 and C6; rectifies the signals at the only frequency of 3 kHz, thanks to the diode D2; and finally compare the voltage Vs with a threshold Vref. From this comparison results a square signal called proportional PWM, traditional signal for controlling a
variateur moteur sans perte de charge. motor variator without pressure drop.
Le principe est mieux compris a l'examen de la figure 7 qui illustre le signal de commande PWM ( VM1 g) dont les o creneaux augmentent en largeur en fonction du depassement de ['amplitude du signal module amplifie et filtre (VD2:2) par The principle is better understood on examining FIG. 7 which illustrates the PWM control signal (VM1 g) the slots of which increase in width as a function of exceeding the amplitude of the signal of the amplified and filtered module (VD2: 2) through

dissipation par perte thermique dans le transistors M1. heat loss dissipation in the M1 transistors.
