Abstract
A telecontrol system for the remote execution of functions comprising actuation of devices in a motor vehicle, for example operation of courtesy lights and locking and unlocking of the doors, comprises a receiver module mounted on the vehicle and an emitter unit carried by the user for transmitting coded radio signals to the receiver module. A data signal configuring circuit of the receiver module has a detection threshold level which is regulated according to predetermined zones of functional ranges between the emitter and the receiver module, around the vehicle, in such a way that a function on the vehicle which is controlled by the emitter is only validated if the emitter is in the appropriate zone of functional range.
