Definitions
- the present invention relates to a method for determining interference contacts on a door handle contact detection sensor.
- the invention applies in this case to the automotive field.
- the door handles of vehicles are equipped with capacitive sensors for approach detection and / or contact of a user.
- the approach and / or contact detection of a user coupled with the recognition of an electronic badge "free hand" remote access control it carries, allows the locking and unlocking of remote sashes of the vehicle.
- the user wearing the corresponding electronic badge and identified by the vehicle
- touches the door handle of his vehicle the opening of the vehicle is automatically unlocked.
- the door handle By pressing a specific point on the vehicle's door handle, called the “unlocking zone”, the door opens without the need to unlock it manually.
- the user still wearing the necessary badge and identified by the vehicle, wants to lock his vehicle, he closes the door of his vehicle and momentarily presses on another specific place of the handle, called “locking zone”. This action automatically locks the opening of the vehicle.
- Some more efficient locking / unlocking systems allow the user to close all the power windows of his vehicle when he leaves his vehicle before locking it. For this, once the door closed, it remains the hand resting on the locking zone of the door handle a few more seconds, the time required (about 30 seconds) to close the windows of his vehicle.
- the on-board electronic system of the vehicle receives this lock command and then coordinates the closing of the windows of the vehicle and locks the vehicle. This mode is called comfort lock or also called "comfort lock" in English.
- the capacitive sensors most often integrated in the driver's door handle of a vehicle in the precise areas of locking and unlocking, operate by counting the number of charge transfers N of a detection capacitor C e , a detection electrode, to a storage capacity C s of much higher capacity (see Figure 1). Via a supply voltage V C c and two switches S1 and S2, the detection electrode C e is charged, then discharges in the storage capacity C s until a voltage threshold value V s across the storage capacitor C s is reached.
- the number of charge transfers N of these detection sensors is therefore continuously compared with a threshold number of charge transfers N th below which approach and / or contact detection is performed. It is important to note that apart from the detection phases, the value of the number of charge transfers N can also vary. This is due to the impact of ambient conditions such as temperature or humidity in the sensor which disturb the capacity of the detection electrode C e .
- the threshold number of charge transfers N t h is not a fixed value, and is determined from the number of charge transfers N measured outside the detection phases, to which a tolerance ⁇ is removed.
- This tolerance ⁇ is a number of fixed charge transfers (for example equal to 4, for a value of the number of charge transfers N equal to 900) and has been calibrated beforehand to allow rapid and effective detection of approach and / or or contact.
- the threshold number of charge transfers N th is determined from this number N, it follows that the number load transfer threshold N th is not fixed either and varies according to the ambient conditions. However, during detection phases, the threshold number of charge transfers N th is not adapted and remains throughout the detection phase equal to the last value recorded before the detection, that is to say before the decrease. the number of load transfers N.
- This variation also known as the adaptation of the load transfer threshold number N t h is beneficial, since it avoids false approach and / or contact detections due for example to the ambient temperature which would reduce the number of load transfers N below the load transfer threshold number N th if the latter was not adapted.
- the load transfer threshold N th is adapted, that is to say calculated from the last 32 values of the number of charge transfers N. These being measured at a recurrence of 60 ms, this amounts to an adaptation occurrence of the charge transfer number N th of approximately 2 seconds.
- the particular mode of the comfort lock also functions as follows:
- This mode of comfort locking is limited in time; it is considered that the windows are closed in the space of a few tens of seconds (approximately 30 seconds), in other words, they have plenty of time to close if the user remains pressed for a maximum of 30 seconds on the locking zone.
- This maximum duration is calibrated in the contact detection sensor and the load transfer threshold N th is not adapted during these detection phases which may have a maximum duration equal to this maximum duration of 30 s (in our example ). Once this duration has elapsed, even if the user remains pressed on the locking zone, the detection sensor resumes the adaptation of the load transfer threshold number Nth.
- FIG. 2 This phenomenon occurs when water of a certain density, especially salt water mixed with ice or slush mixed with salt, is introduced into the water. handle.
- a vehicle 1 equipped with windows 7, door 2 (in this case the door on the driver's side of the vehicle) having a handle 3 equipped with a sensor. contact detection 4. It also comprises an on-board electronic locking / unlocking system 6, connected to the windows 7, to the door 2 and to the detection sensor 4.
- the detection sensor 4 defines the locking zone L around this sensor 4.
- the handle 3 is also equipped with drainage holes 8a and 8b of the infiltrated water. When water E infiltrates into the handle 3, it stagnates in the lower part of the handle 3, as shown in FIG. 2, and then flows slowly through the evacuation holes 8a and 8b provided for this purpose. effect. When the user closes the door 2 or slams it violently, water E is thrown onto the detection sensor 4 (see Figure 3).
- the detection sensor 4 is at the rear of the handle 3 and by displacement of the water E due to the closure of the door 2, the water E is found projected in the direction from the front of the vehicle F towards the rear of the vehicle R, that is to say that it is projected against the detection sensor 4 and triggers a contact detection on the locking zone L.
- These false contact detections frequently occur .
- the majority of the handles 3 of doors 2 are not waterproof.
- the evacuation holes 8a and 8b provided for evacuating the infiltrated water E does not evacuate fast enough a high density water of the type salt water mixed with ice. This type of water E can therefore remain long enough in the handle 3 on the detection sensor 4 and trigger false contact detections.
- a contact detection occurs even before the door 2 is closed, and without the user has requested.
- the information concerning this detection of contact on the locking zone L is sent to the on-board electronic locking and unlocking system 6 of the vehicle 1 but even before the door 2 is closed.
- the on-board electronic system 6 ignores this information, arrived too early, and does not proceed to any locking, even when the door 2 is finally closed.
- the detection sensor 4 In the case of vehicles 1 equipped with the comfort locking mode, if the water E persists on the detection sensor 4 for a sufficiently long duration, then the detection sensor 4 remains in detection mode during this period and the threshold of the number of charge transfers N th is not adapted; this duration may be equal to the maximum duration of this mode of comfort locking 6 that is to say 30 s in our example. No contact detection by the user is therefore possible during this maximum duration. If the user, once the door 2 closed, touches the locking zone L, the detection sensor is already in detection mode (that is to say that the number of load transfers N is already below the threshold N, h ), this contact by the user on the sensor will not be detected.
- FIG. 4 graphs as a function of the time tps, the number of charge transfers N of the detection sensor 4 as well as a detection indicator D ,, for the following cases:
- case A the door 2 is closed at time P1, the user touches the lock zone L for a short time corresponding to the duration of engagement of the simple locking mode.
- the number of charge transfers N goes below the threshold N th and therefore a contact detection is performed.
- the detection indicator D A has the value 1.
- the detection information and its duration are sent to the on-board electronic locking / unlocking system 6 of the vehicle 1 which deduces a simple lock request and then controls this lock.
- case B the door 2 is closed at time P2.
- This duration t 2 triggers the comfort locking mode.
- the number of charge transfers N falls below the threshold of the number of charge transfers N th and therefore a contact detection is performed.
- the detection indicator D B has the value 1.
- the contact detection information and the contact time are sent to the on-board electronic locking / unlocking system 6 of the vehicle 1 which then controls the comfort lock.
- the threshold of the number of charge transfers N t h is not adapted during this period t 2 and it retains its value (which is the last value recorded before the detection).
- This duration t 2 may be equal to the maximum duration of the lock mode of
- the contact of the water E on the detection sensor 4 momentarily lowers the number load transfers N below the threshold of the number of load transfers N t h and therefore a contact detection on the locking zone L is carried out while the door 2 is not yet closed, that is to say say before the moment P3 door closing 3.
- the detection indicator D c takes the value 1.
- the water E can flow through the evacuation holes 8a and 8b for a period of time t 3 . Even if this duration is relatively short, it is disadvantageous for the user, since the latter can not lock his vehicle 1 from the moment P3 and until the duration t 3 has elapsed,
- the detection indicator D D takes the value 1.
- the water E stagnates on the detection sensor 4 and can not flow sufficiently quickly, that is to say that it persists on the detection sensor 4 for the duration t .
- this duration t 4 is equal to the maximum duration of the comfort lock mode, the user can no longer lock his vehicle as long as the maximum duration t max of this mode has not passed, which is relatively long (30 seconds in our example).
- the number of load transfers N is already below the threshold number N t h, and since the latter is not adapted during this maximum duration t max , no other contact detection (in this case that from the user) is not possible.
- the object of the present invention is therefore to propose a method for determining parasitic contacts on a door handle contact detection sensor making it possible to distinguish a contact on the sensor originating from a parasitic phenomenon, in this case due to the presence water, a contact from the user. This is to allow the user to lock his car even when there is water on the sensor. This method is particularly applicable to vehicles equipped with the comfort lock mode.
- the method for determining interference contacts on a door handle contact detection sensor of a motor vehicle said detection sensor defining a lock control area and being connected to an on-board electronic locking and unlocking system, said method comprising:
- the method further comprising the steps of:
- the method for determining interference contacts proposes, during step b, that the evaluation of the number of charge transfers is carried out as follows:
- the invention proposes, during step c, to adapt the threshold number of charge transfers as follows:
- the first value of the load transfer threshold number is calculated from the average of the number of charge transfers calculated over the predetermined evaluation period from which a first tolerance is removed; , The following values of the threshold number of load transfers are calculated from a moving average of the number of load transfers to which a second tolerance is removed.
- the first tolerance and the second tolerance are equal.
- the evaluation time is less than the lock mode's lock time.
- steps a, b and c are performed by the detection sensor. Alternatively, they can be performed by the on-board electronic system for locking / unlocking the vehicle.
- the invention also relates to a motor vehicle incorporating a device embodying the method of determining unwanted contacts described above.
- FIG. 1 represents a schematic view of a capacitive sensor for approach and / or contact detection and has already been explained
- FIG. 2 represents a schematic view of water infiltration in a vehicle door handle equipped with an approach and / or contact detection sensor and has been explained previously,
- FIG. 3 represents a schematic view of the phenomenon of false contact detections due to the projection of the water infiltrated onto the approach and / or contact detection sensor during the closing of the door and has already been explained previously.
- FIG. 5 graphically represents the method for determining the spurious contacts on the contact detection sensor, according to the invention.
- the method for determining interference contacts on the detection sensor 4 located in the door handle 3 of the vehicle 1, illustrated in FIG. 5, proposes: • to evaluate the evolution of the number of load transfers N A , N D 'during a detection, in order to distinguish the contact detections coming from the user of the "parasitic" contact detections coming from the infiltrated water E then ,
- the invention proposes to adapt the load transfer threshold N D l h in order to be able to detect any next contact coming from the user on the locking zone.
- the first value of the load transfer threshold number Name once the evaluation period t has elapsed, is calculated from the average of the number of load transfers N D MOY calculated over the predetermined duration of evaluation t at which we remove a first tolerance ⁇ 1.
- the value of the first tolerance ⁇ 1 may be equal to that of the prior art ⁇ (that is to say equal to 4 in our example), or may be redefined,
- the following values of the load transfer threshold number N D th are calculated from a moving average of the number of load transfers ⁇ 0 ⁇ measured at which a second tolerance ⁇ 2 is removed.
- the first and second tolerance ⁇ 1 and ⁇ 2 are equal.
- the predetermined duration of evaluation t of the average value of the number of charge transfers ⁇ ⁇ ⁇ , N DM OY is of course much less than the duration to engage the comfort lock mode t 2 .
- the predetermined evaluation time t is less than the duration of engagement of the simple lock mode ti; this is to detect as quickly as possible any false contact detection due to infiltrated water without the user being penalized.
- FIG. 5 illustrates the process according to the invention as well as its advantages:
- the minimum value of the number of load transfers N D MIN reached at time t DM iN is much lower than the average value of the number of load transfers N D MOY calculated from this instant t DM iN during the evaluation period t. Therefore, the contact detection comes from the action of water E projected on the detection sensor 4 when closing the door 2 by the user.
- the threshold of the number of charge transfers N D th is then adapted, using the average of the number of charge transfers N D MOY calculated since the beginning of the detection.
- the adapted load transfer threshold number N D th is below the threshold number of charge transfers N D th (see FIG. 4) of the prior art and is of course below the number of charge transfers ⁇ 0 ⁇ measured during detection.
- the detection sensor does not have sufficient electronics to integrate the invention, for example in the case where the detection sensor only transmits the number of charge transfers N to the on-board electronic system (the latter being equipped to compare this value with a threshold number of charge transfers N t h that it has in memory and thus determine the detection phases), then the invention will be realized in the software of the on-board electronic system of the vehicle itself.
- the invention therefore proposes to determine the contact detections on the locking zone resulting from the action of water on the detection sensor and then to adapt the threshold number of charge transfers during this detection, so that the latter is less than the number of load transfers measured and thus be able to detect any next contact from the user on the lock zone.
- the threshold of contact detection is thus lowered even in the presence of water on the sensor, the user can at any time lock his car and is no longer in the presence of a car whose doors are closed and it does not can no longer lock, as in the prior art.
- the invention is not limited to the problem of the projection of water on the detection sensor inside the handle and can also be applied to any other parasitic phenomenon which creates a false detection of contact by the sensor, for example ice projected on the locking zone on the outside of the handle when the user closes the door.
