A corner sensor for a motor vehicle capable of communicating over a wireless communication link with an authentication device and including: an array of antennae; and an electronic control unit configured to: determine the phase difference between the segments received by the antennae; determine the probability of each angle of incidence over a range of angles that is predetermined on the basis of the determined phase differences and of a predefined table, so as to determine a probability profile; measure the power of the segments received by the antennae of the array of antennae so as to determine a power profile; determine the actual angle of incidence of the signal by multiplying the probability profile with the power profile; and send the value of the determined actual angle of incidence to a central electronic control unit of the vehicle.

A process for detecting a portable user device in a predetermined zone on the inside or outside of a vehicle by a detection device onboard the vehicle. The high-frequency, BLE type communication includes a first signaling mode and a second communication mode, the first mode including: positioning the portable device at a predetermined fixed distance from the detection device, transmitting a signal by the detection device with predetermined transmission power on a channel. As long as the detection device is receiving a response signal from the portable device, repeating transmission of the signal at the same transmission power on other channels, otherwise, repeating transmission of the signal on a channel with reduced transmission power, and if the detection device no longer receives a response signal, comparing the transmission power to a predetermined threshold transmission power, and applying a correction to the transmission power during the second mode.

A system for detecting the operation of the motor or engine of a motor vehicle equipped with at least one tire-pressure-monitoring-system transmitter including: a low-frequency stage including a resonant stage connected in series with an antenna, a processing stage, a first switch and a second switch, the first switch being connected to at least two capacitors so as to control the parallel connection of at least one of the capacitors, the second switch being connected to at least two resistors so as to control the parallel connection of at least one of the resistors, outputs of the low-frequency stage being arranged to receive input from the processing stage, in order to transfer the perceived signal to a processor of the signal, which is configured to compare the level of the perceived signal to a preset threshold level.

A method for detecting and estimating an angle of rotation on itself, about a mounting axis, of a wheel unit with an acceleration sensor, the wheel unit being associated with a tire mounted on a rim, forming a wheel, the sensor detecting a gravitational force during the rotation of the wheel, forming a sinusoid. The wheel unit is mounted on the wheel with the acceleration sensor directly or indirectly inclined with respect to a plane tangential to the rim. The angle of rotation on itself of said wheel unit and therefore of the acceleration sensor at a given instant is estimated by comparing at least one parameter of the sinusoids that are obtained for the wheel unit in an initial mounting position on the wheel and in its position at this given instant, respectively.

A method for identifying at least one emitter for monitoring the tire pressure of a motor vehicle by association with one of the wheels of the motor vehicle. The method includes: for each emitter monitoring tire pressure, reconstructing an intermediate-frequency signal from the radiofrequency signal and a reference signal, determining the FFT of the intermediate-frequency signal, determining whether there is a frequency deviation of the intermediate-frequency signal, determining the side of the vehicle on which the emitter monitoring the pressure of a tire is placed, acquiring a signal from the anti-lock braking system for at least one of the wheels on the side on which it was determined that the emitter for monitoring the pressure of a tire is placed, and determining the position of the emitter for monitoring the pressure of a tire depending on the deviation and on the at least one signal from the anti-lock braking system.

A method for detecting the presence of a human hand on an opening element of a motor vehicle. The method includes determination of a power variation profile and detection of the presence of a human hand on the opening element being performed when the determined profile corresponds to a predetermined reference profile characterized by an increase followed by a first decrease in the power value, characterizing the approach of a human hand, followed by a stagnation and a second decrease in the power value, characterizing contact of a human hand with the opening element of the vehicle.

A method for determining the start of movement of a motor vehicle equipped with a system for monitoring tire pressure of a motor vehicle. Communication between the receiver and each pressure monitoring system emitter being subjected to a Doppler effect so that a periodic component is inserted by the emitter into the signal emitted to the receiver. The method includes: acquiring the intermediate-frequency signal before demodulation by a processor to extract data carried by the radiofrequency signal, determining the FFT of the IF signal, determining the average value of the FFT of the IF signal over a preset duration, and determining whether there is a frequency deviation by comparing the instantaneous value of the fast Fourier transform to the average value of the fast Fourier transform, if so, determining whether the emitter for monitoring the pressure of a tire is moving and that the vehicle is moving.

A method whereby a central unit carried on board a motor vehicle can identify the wheels of a motor vehicle, by locating a radiofrequency black spot for transmissions between a wheel unit with which a wheel of a motor vehicle is equipped and a wheel-monitoring central control unit carried on board the vehicle, a wheel angle encoding independent of the transmission being in any case performed in order to measure the true rotation of the wheel at a given instant. A string of successive frames providing full angular coverage of the wheel is transmitted from the wheel unit, a receive rate for the frames being established and analyzed in order to detect at least one spot of poorer reception corresponding to the at least one black spot, the angle encoding providing an angle of rotation of the wheel at the instant of detection of the at least one black spot.

A self-adaptive method for assisting in the inflation of tires of a vehicle that is stationary in an immobilization mode, the method including continuously measuring at least the pressure of each tire by way of a wheel unit, transmitting signals on the state of the tires between each wheel unit and a central unit, these signals being transmitted by each wheel unit through frequency-shift keying between two first predetermined frequencies defining a first frequency band.
