Abstract: The invention relates to a process of correction for determining, by a central unit that is provided with a receiver and that equips a vehicle, the longitudinal position, either on the front wheel assembly or on the rear wheel assembly, of emitters that are each mounted on a wheel of said vehicle. This process consists of, in a preliminary phase, determining and storing, for each wheel of the vehicle, a reference field level, received by the receiver and having for an origin an emitter that is combined with said wheel and that exhibits a given mean radiated power.

Abstract: Each sensor is provided with an emitter and the vehicle is provided with a corresponding receiver adapted to receive signals emitted by each sensor. The receiver is provided with at least one antenna disposed such that it is not located substantially equidistantly from the sensors, the antennas being located on a same side of the vehicle. The location of the sensors is carried out by analyzing the power of the field received by the receiver of each antenna for each sensor, the field power received by one antenna being the greater, the nearer to the antenna is the sensor that emitted the corresponding signal.

Abstract: A data transmission method for a tire-pressure monitoring system (10) of a vehicle. The data is transmitted by wheel units (12) to a central computer (13) located in the vehicle. The method comprises: a data transmission phase in parking mode, over a first period; and a data transmission phase in running mode, over a second period shorter than the first period. The method is characterized in that a natural time lag between various internal clocks with which each wheel unit (12) is equipped is used to prevent collisions between transmissions from the various wheel units of one and the same vehicle.

Abstract: A communication method between a badge and a vehicle whereby a low range transmitter associated with the vehicle transmits a low frequency signal towards the badge which replies by sending a RF signal of longer range towards the vehicle. A receiver of the badge designed to receive a RF signal is placed in standby mode in accordance with a predetermined rhythm and a transmitter associated with the vehicle sends during a standby phase of the badge a RF signal whereto the badge replies with a RF signal. The invention is applicable to hands-free systems.
