Definitions
- the invention relates to a method and a device for locating the longitudinal position, either on the front axle or on the rear axle of a motor vehicle, with wheels equipped with an electronic box adapted to transmit, destined for a central unit mounted on the vehicle, signals representative of operating parameters of each wheel including, in addition, an identification code of the latter
- More and more motor vehicles have, for security purposes, surveillance systems comprising sensors mounted on each of the wheels of the vehicle, dedicated to the measurement of parameters, such as the pressure or temperature of the tires fitted to these wheels, and intended to to inform the driver of any abnormal variation of the measured parameter.
- These surveillance systems are conventionally equipped with an electronic box mounted on each of the wheels of the vehicle, integrating, in addition to the aforementioned sensors, a microprocessor and a radiofrequency transmitter (or RF transmitter), and a central unit for receiving the transmitted signals. by the transmitters, comprising a computer integrating a radio frequency receiver (or RF receiver) connected to an antenna.
- a first method of localization consists of integrating an accelerometer into each electronic box, and to implement a locating technique based on statistical methods consisting in comparing the accelerations of the different wheels to obtain information on the position respective of each of said wheels.
- a second location method consists in using three low frequency antennas each positioned near one of the wheels of the vehicle, and in performing a locating procedure of successively exciting each of these three antennas by the emission of a low magnetic field. frequency.
- the electronic unit mounted on the wheel located near the excited antenna transmits, in response and to the central unit, a low frequency signal comprising an identification code of said housing, so that the successive excitation of the three antennas leads to the location of the three electronic boxes mounted on the wheels adjacent to these antennas, and by deduction, to the location of the fourth housing.
- the present invention relates to a third method dedicated to the location of the longitudinal position (front axle or rear axle) of the wheels of a vehicle, and for the main purpose of providing a very efficient locating method in terms of responsiveness and reliability, the implementation of which generates a total cost of production significantly lower than that generated, for the same final result, by the implementation of the two current methods discussed above.
- the invention relates to a method for locating the longitudinal position, either on the front axle or on the rear axle of a motor vehicle, with wheels equipped with an electronic box adapted to transmit, destined to a central unit mounted on the vehicle, signals representative of operating parameters of each wheel further comprising an identification code of the latter.
- this localization method consists of integrating a vibration sensor into each electronic box, and:
- a preliminary phase of characterization to analyze, with the engine running, the signals delivered by the respective vibration sensors of a wheel mounted on the front axle and a wheel mounted on the rear axle, so as to establish a criterion of differentiation of said signals, and to establish a procedure for locating the longitudinal position of the wheels by analyzing the signals delivered by the different vibration sensors, and to derive from this analysis, by application of the differentiation criterion, information on the longitudinal position of each wheel.
- any sensor such as advantageously a piezoelectric type sensor, designed to provide a representative signal, in particular in terms of amplitude and frequency, vibrations or mechanical shocks to which the said sensor is subjected.
- the invention therefore consisted of:
- vibration sensors required for the implementation of the invention consist of sensors of a simple and proven technology and lead, for the same final result, to an overall cost of installation (supply, implementation and adaptation software) lower than that of an installation with accelerometers.
- the vibration sensors used according to the invention lies in their robustness, which is particularly adapted to the severe environment conditions of the electronic boxes.
- the criterion of differentiation is established from the analysis and comparison of the amplitudes of the signals delivered by two vibration sensors equipping respectively a wheel mounted on the front axle and a wheel mounted on the rear axle.
- the location of the longitudinal position of the wheels results from a simple comparison of the amplitudes of the signals delivered by the vibration sensors.
- the invention extends to a device for locating the longitudinal position of wheels of a motor vehicle, comprising:
- FIG. 1a is a schematic top view of a vehicle equipped with a monitoring system associated with a device according to the invention for locating the longitudinal position of the wheels of said vehicle,
- FIG. 1b is a schematic detailed perspective view showing a wheel portion of this vehicle as well as the electronic unit equipping it,
- FIGS. 1a and 1b show the signals delivered by vibration sensors according to the invention respectively mounted on a front wheel ( Figure 2a) and a rear wheel ( Figure 2b).
- the locating device according to the invention shown by way of example in FIGS. 1a and 1b is intended for locating the longitudinal position (front wheel or rear wheel) of wheels of a vehicle.
- This locating device is more specifically intended to be installed on vehicles equipped with a tire pressure monitoring system such as that shown in FIG. 1a, fitted to a vehicle 1 having a motor M equipped with four conventionally road wheels. a tire: two front wheels 2, 3 and two rear wheels 4, 5.
- Such monitoring systems conventionally comprise, firstly, associated with each wheel 2-5, an electronic box 6-9, for example secured to the rim of said wheel so as to be positioned inside the envelope of the tire.
- Each of these electronic boxes 6-9 includes, for example, sensors 1 1 dedicated to the measurement of parameters, such as pressure and / or tire temperature, connected to a computing unit 12 microprocessor electrically powered by means of a button cell 13, and connected to an RF transmitter connected to a high frequency antenna 14.
- the monitoring system also comprises a centralized computer or central unit 10 located in the vehicle 1, comprising a microprocessor and integrating an RF receiver adapted to receive the signals emitted by each of the four electronic boxes 6-9.
- a monitoring system and in particular its central unit 10 are designed to inform the driver of any abnormal variation of the parameters measured by the sensors 11 associated with the wheels 2-5.
- the locating device Associated with this monitoring system and forming an integral part of the latter, serves to associate each signal received by the central unit 10 with information concerning the longitudinal position of the wheel. 2-5 equipped with the electronic box 6-9 at the origin of this signal.
- this locating device comprises a vibration sensor 15, for example of piezoelectric type, integrated in each electronic box 6-9 and adapted to provide a representative signal, in particular in terms of amplitude and frequency, vibrations or mechanical shocks to which the said sensor is subjected during operation of the motor M.
- vibration sensors 15 positioned in accordance with the invention have the following particularities, which are decisive according to the principle of the invention:
- the two sensors 15 fitted to the wheels closest to the engine M are subjected to vibrations (and thus deliver signals of amplitude greater than that of the vibrations to which are subjected the two other sensors 15 equipping the two rear wheels 4, 5.
- the locating method according to the invention described above thus makes it possible, by means of installing a simple low-cost vibration sensor in each electronic box on a vehicle wheel, to locate the longitudinal position very quickly and reliably. of the said wheel.
