The vehicle includes an interior space (204) delimited by walls (207,208,209,232) and an on-board signal transmission device for communicating with a portable receiver device for putting into play a distance control method, this signal transmission device having an emitting antenna (206). The antenna includes a closed loop conductor for producing a magnetic field (B), this loop configured in a manner to extend from these walls along a detection zone in which the presence of the portable receiver device is to be detected. The conductor loop includes the conducting walls of the vehicle. |
