DISPOSITIF ANTIVOL DE COMMANDE A DISTANCE ESSENTIELLEMENT DE VEHICULES AUTOMOBILES

摘要

The present invention relates to a security device of the type comprising a portable emitter and a fixed receiver interrupting the supply of the motor of a vehicle when the distance between the portable emitter and the fixed receiver exceeds a certain value. The emitter advantageously emits coded sequences and comprises a clock controlling the supplying of the power stage. The receiver advantageously comprises a time-delay circuit maintaining the output for a period at least equal to the period separating two coded sequences.
