- TITLE METHOD FOR DETECTING PRESENCE INSIDE A LOCKED VEHICLE, ASSOCIATED DETECTION DEVICE
- the invention relates to a method for detecting presence inside a vehicle that has been previously locked, an associated detection device.
- the invention applies particularly to the detection of young children, or a baby who may have been forgotten on the rear seats when the driver has left the vehicle and locked it.
- sensors already existing on the vehicle for example UWB frequency transmitters/receivers, “Ultra Wide Band” or Ultra Wide Band, which are located on the vehicle in order to allow “hands-free” access to the vehicle and/or “hands-free” starting of the vehicle. These sensors are then used to detect the movement of breathing, i.e. the heart rate of a human located in the vehicle.
- UWB transmitters/receivers are used for presence detection inside the vehicle, they are then not reliable enough to distinguish the presence of a child from that of an adult. Indeed, if it is detected that an adult is present in the back seat alone or with a child, it is not necessary to trigger an alert.
- the invention therefore proposes a method for detecting presence inside a vehicle; as well as an associated detection device, making it possible to discriminate the presence of a child from that of an adult in a reliable and inexpensive manner.

Reception of the reflected waves comprising static waves and dynamic waves, and filtering of the static waves representing fixed obstacles, c. Application of a low-pass filter to the received dynamic waves, d. Determination of a distance with a dynamic target from the filtered dynamic waves, e.
- the method further comprises a determination and an amplitude comparison between an amplitude of the first signal and an amplitude of the second signal and in that the detection of a presence of a child or an adult is a function of the result of the phase shift comparison and the amplitude comparison between the two signals.
- the extraction of two oscillating signals is carried out by demodulation of the received dynamic waves.
- the extraction of the two oscillating signals is carried out using a prior spatial scan of the waves emitted towards the target.
- the invention also relates to a device for detecting a presence in a motor vehicle, comprising at least one internal ultra-wideband transmission-reception module capable of transmitting towards the interior of the vehicle, said device being remarkable in that it is also capable of: a.

Determining a distance with a dynamic target, e.
- the detection device is further capable of: a. determining an amplitude of each of the two signals, b. comparing the two amplitudes with each other c. detecting the presence of a child or an adult based on the result of the comparison between the two amplitudes and based on the comparison between the phase shift and the predetermined phase shift value.
- the device is capable of demodulating the received dynamic waves to extract the two oscillating signals.

- Figure 10 is a flowchart representing the detection method according to the invention.
- the device comprises at least one internal module 11 for transmitting and receiving in ultra wide band ULB capable of transmitting towards the interior of the vehicle, that is to say in a multidirectional manner in the passenger compartment of the vehicle.
- the internal module 11 is located centrally in the passenger compartment in order to be able to emit R waves throughout the passenger compartment.
- Ultra Wide Band (ULB) communication is understood to mean radiofrequency communication which is based on the transmission of pulses of very short duration, often less than a nanosecond. Thus, the bandwidth can reach very high values between 250 and 500 MHz.
- the internal transmission-reception module 11 is electronically connected to a central control unit 10 which manages the transmission and reception of data via said module and which also processes this data.
- a central control unit 10 which manages the transmission and reception of data via said module and which also processes this data.
- the central control unit 10 and the internal transmission-reception module 11 may be one and the same and be integrated together in the same unit.

- Means M7 for comparing the phase shift Acp and a predetermined phase shift value AcpS, h.
- M8 means of detecting the presence of a TG2 child or a TG1 adult depending on the result of the comparison.

- the central control unit 10 also comprises a processor 100 and a memory 101 (see FIG. 9) in which instructions are recorded for configuring the processor to execute certain particular processing operations, in particular to implement the steps of the detection method, according to the embodiment as described below.
- the extraction means M5 consist of a demodulation M51 (see FIG. 9) of the reflected waves which make it possible to distinguish between two oscillating signals SAB and SCH.
- the techniques for demodulating signals in phase or out of phase with each other are known to those skilled in the art and will not be detailed further here.
- the extraction means M5 consist of a prior spatial scan of the waves emitted towards the target TG1, TG2 and by a method of spatial distinction M52 of the reflected waves.
- the spatial scan uses the known state-of-the-art technique of beamforming, also called "beamforming" in English. This technique makes it possible to modify the radiation angle of the antenna of the internal module according to a vertical plane.
- the angular resolution depends on the frequency of the emitted waves. In the ultra-wideband frequency band, the minimum resolution to be used is 10°. The angular scan is +/-30 ° to cover the abdomen and torso of a target TG1, TG2.
- the wave emission means M1 emit R waves in phase at 0° and phase-shifted by 90° between them, according to a plurality of frames T1, T2...Tn of duration d of 100 ns each for a predetermined duration At of 10 seconds for example (see figure 5).
- the means for filtering static waves M2 can be presented in different forms, known from the state of the art, said filtering means can consist of the analog ball filter or called “Loopback filter” in English, or the decomposition into singular values, also called “singular Value decomposition SVD” in English, or even averaging filters such as the Kalman filter or methods for calculating averages.
- the low-pass filtering means M3 comprise a low-pass filter with a cut-off frequency of 1 Hz to keep only a signal representative of the movements linked to breathing.
- the means M4 for determining a distance D with a target TG1, TG2, comprise means for determining a time of flight of the waves, thus allowing the calculation of the distance.
- the device D is also capable of determining an amplitude ACH, AAB of each of the two signals SCH, SAB and of comparing the two amplitudes ACH, AAB with each other.
- the device D then also comprises means for determining the amplitude ACH, AAB of the two signals SCH, SAB and for comparing the two amplitudes with each other (not shown in FIG. 9).
- the device D then comprises means M8' for detecting a child TG2 or an adult TG1 depending on the result of the comparison between the phase shift Acp and the predetermined phase shift value Acp S and depending on the comparison result between the two amplitudes ACH, AAB.
- the predetermined phase shift value AcpS is between 30° and 150°.
- a plurality of ultra wide band ULB R waves are emitted into the passenger compartment of the vehicle for a predetermined duration At.
- This plurality comprises in-phase I waves and out-of-phase Q waves, i.e. offset by 90°.
- the R waves are sent in successive frames T1, T2...Tn with a duration of approximately 500 ps and an interval between each frame of 10 ms.
- the duration of emission of the waves to detect a presence is 10 seconds.
- the maximum delay between the emission of a wave and the reception of the corresponding reflected wave is 100 ns.
- a portion of the R waves thus emitted is reflected by any obstacle, whether fixed or dynamic, including any body in the passenger compartment, whether that of an adult TG2 or that of a child TG1 (see figure 3).
- the reflected waves RTG1, RTG2 are received, during the second step E2 by the internal transmission-reception module 11 (see FIG. 3).
- the internal transmission-reception module 11 On the left of FIG. 7, there is a graph illustrating the amplitude A(V) according to the time t(s) of the reflected waves RTG2, RTG1 and received by the internal module 11.
- the waves thus reflected include so-called “static” waves and so-called “dynamic” waves.
- Static” waves are waves reflected by static obstacles and with which the distance between the internal module 11 and the obstacle does not vary.
- “Dynamic” waves are waves reflected by obstacles in motion for example, and with which the distance between the internal module 11 and the obstacle varies.
- a moving obstacle may be the torso or abdomen of an individual who is breathing. Indeed, during breathing the abdomen or torso moves by approximately 4 mm, the torso and abdomen are therefore dynamic targets.
- the detection method according to the invention proposes to filter the static waves with a filter F1 in order to keep only the dynamic waves.
- the filtering method is known to those skilled in the art as specified above: the filter can come in different forms, known from the state of the art, said filtering means may consist of the analog ball filter or called “Loopback filter” in English, or the singular value decomposition, also called “singular Value decomposition SVD" in English, or even averaging filters such as the Kalman filter or methods of calculating averages.
- FIG. 6 This filtering is illustrated in Figure 6.
- FIG. 6 At the top of Figure 6 is a graph representing the amplitude A in volts of the reflected R waves RTG1, RG2 as a function of time t in seconds.
- the waves represented here include static waves and dynamic waves.
- FIG. 6 At the bottom of Figure 6 is a graph representing the amplitude A of the reflected waves according to the time t in seconds after the filtering of the static waves.
- the signal S thus obtained is a sinusoidal signal whose amplitude and frequency are representative of the amplitude and frequency of the movement of the dynamic obstacle.
- a fourth step E4 it is proposed to apply a low-pass filter F2 with a cut-off frequency equal to 1 Hz to this signal, in order to keep only a signal S representative of the movement of a torso or an abdomen during breathing.
- a distance D is determined between the internal module and the dynamic target TG1, TG2.
- the distance D is determined by the time of flight of the UWB waves. This is known to those skilled in the art. Said distance D makes it possible to determine the position of said target TG1, TG2 and to extract the sinusoidal signals coming from the same target.
- a sixth step E6 two oscillating signals are extracted from this signal S; a first signal representing a movement of a torso SCH, and a second signal representing a movement of an abdomen SAB.
- the signal S is demodulated in phase and in phase opposition.
- the demodulation is a method known to those skilled in the art and will not be detailed further here.
- a spatial scan of the ULB emitted waves is carried out towards the target TG1, TG2 detected at the distance D determined beforehand.
- This scan for example at an angle of 10°, makes it possible to send a plurality of R-wave beams towards the target and receive two types of reflected signals. Those reflected by the abdomen AB and those reflected by the torso CH.
- the spatial scanning is illustrated in Figure 8.
- the internal module 11 emits waves R1, R2 spatially offset from each other by a few degrees. For example, by 10 degrees, thus scanning the upper part of the body, i.e. the torso CH, and the lower part, the abdomen AB of the target TG1, TG2.
- the two oscillating signals spatially offset from each other are received, the signal reflected by the torso SCH, representing the breathing signal of the torso CH and the signal reflected by the abdomen SAB, representing the breathing signal of the abdomen AB.
- FIG. 3 includes a graph representing the desynchronized movements of the torso CH and the abdomen AB of a baby TG1 when the latter breathes. It can clearly be seen that when the abdomen AB rises, the torso CH collapses and vice versa. Consequently, the reflected waves RTG1 received from the torso or abdomen of a child TG1 consist of two types of waves, of different amplitude and frequency, a first signal SCH representing the breathing movement of the torso, and a second signal SAB representing the breathing movement of the abdomen.
- the invention therefore proposes to extract these two signals SCH, SAB, representative of the breathing movement of the torso and that of the abdomen, and to compare them in order to determine whether the presence detected in the passenger compartment is that of an adult TG2 or that of a child TG1.
- phase shift Acp is then compared to a predetermined phase shift value AcpS (step E8a), for example greater than 30°.
- phase shift Acp is greater than the predetermined phase shift value AcpS, then it is considered that the presence of a child TG1 in the passenger compartment has been detected (step E10).
- phase shift Acp is less than the predetermined phase shift value AcpS, then it is considered that the presence of an adult TG2 in the passenger compartment has been detected (step E9).
- step E7b it is proposed to compare the amplitude of the first signal ACH with the amplitude of the second signal AAB (see step E7b).
- the invention is therefore ingenious, inexpensive and easy to implement.
- the detection method according to the invention makes it possible to reliably and robustly distinguish the presence of a child from that of an adult in the passenger compartment of the vehicle.
