Abstract
Système d'entrée commandé à distance conçu pour un véhicule, tel qu'une automobile. Un processeur de signaux (18) peut couper l'alimentation des sections de traitement du processeur, tel qu'un amplificateur de données (12.6), afin de préserver le courant de la batterie. La séquence de coupure a lieu après la mise en application d'une fonction en réponse à une instruction provenant d'un émetteur manuel (10). La séquence de mise sous tension est déclenchée par la transmission au processeur d'un signal codé (N) lui commandant d'effectuer la mise sous tension. Un signal de données (DB) suit le signal de mise sous tension et provoque le déclenchement d'une fonction du processeur, telle que le déverrouillage des portes. Le processeur ne déclenche cette fonction qu'après la disparition du signal de mise sous tension. Le signal de mise sous tension est constitué par une pluralité d'impulsions codées de tonalité (TP). Un décodeur de tonalité décode lesdites impulsions, ainsi qu'un signal d'instruction (DB) depuis un signal électromagnétique démodulé.Remote controlled entry system designed for a vehicle, such as an automobile. A signal processor (18) can cut power to the processor processing sections, such as a data amplifier (12.6), to conserve battery current. The shutdown sequence takes place after the application of a function in response to an instruction from a manual transmitter (10). The power-up sequence is triggered by the transmission to the processor of an encoded signal (N) commanding it to carry out the power-up. A data signal (DB) follows the power-on signal and triggers a processor function, such as unlocking the doors. The processor does not activate this function until the power-up signal disappears. The power-on signal consists of a plurality of tone coded pulses (TP). A tone decoder decodes said pulses, as well as an instruction signal (DB) from a demodulated electromagnetic signal.
