  • Method for automatically locating a motor vehicle wheel and corresponding locating unit
    Patent number: 6871157
    Abstract: A method for automatically locating a motor vehicle wheel comprises the following steps: transmission by the wheel unit (12a to 12d) of high-frequency signals representing, at least, the wheel pressure whereon the wheel unit is mounted, and a code identifying the wheel; reception by the central unit (11) of the high-frequency signals transmitted by the wheel unit. The method further comprises the following steps: transmission of low-frequency signals by at least a transmission device (14, 14?) mounted on the vehicle proximate to the wheels along a predetermined position, so as to activate the units arranged proximate; reception of the low-frequency signals by the wheel units and in response, transmission of high-frequency signals by the activated wheels, the signal comprising at least the code identifying the activated wheels, and reception of the high-frequency signal by the central unit (11) associated with the code identifying the activated wheels, at the position of the transmission device(s) 14, 14?).

  • Communication method between a badge and a motor vehicle
    Publication number: 20040174248
    Abstract: The invention concerns 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.

  • Method for automatically determining the position of the front and rear wheels of a motor vehicle
    Publication number: 20040083034
    Abstract: The invention relates to a method for automatically determining the position of the wheels of a motor vehicle (10), characterised in that it consists in:—measuring (21) the temperature of each wheel (12) of the vehicle; and determining (23) the position of the wheels on the vehicle according to the temperature measured. The invention also relates to a corresponding position-finding device. The device is particularly suitable for monitoring the pressure inside tires.
