Description of the implementation examples

A method and a device for controlling the opening of a door of a vehicle trunk will now be described in what follows with reference jointly to Figures 1 to 3. The same elements are identified with the same reference signs while throughout the description which follows.

According to a particular and non-limiting example of an embodiment of the present invention, the opening of the trunk door of a vehicle is controlled so as to prevent an object placed in the trunk from falling when the trunk is opened. For this purpose, first information representative of a trunk door opening command is received, for example by a computer of the vehicle's on-board system. Data representative of the detection of the object falling are also received, following receipt of the first information. These data are advantageously received from at least one sensor arranged in the trunk, which is configured to detect a movement of the object in the trunk or a pressing of the object on an interior wall of the trunk door. The opening of the door is then controlled according to this data, one or more actions to prevent the object from falling being implemented when a fall or a risk of the object falling is detected.

There schematically illustrates a rear view of a vehicle 10, according to a particular and non-limiting embodiment of the present invention.

The vehicle 10 is illustrated with the door 101 (also called tailgate) of the trunk 102 of the vehicle 10 in the open position, thus allowing access to the trunk 102 of the vehicle 10. The door 101 is configured to move from a closed position to the open position and vice versa. The closed position of the door 101 makes it possible to close the trunk 102 and prevent any access to the interior of the trunk 102. Conversely, the open position offers access to the interior of the trunk 102.

The vehicle 10 corresponds for example to a vehicle with a thermal engine, with an electric motor(s) or even a hybrid vehicle with a thermal engine and one or more electric motors. The vehicle 10 thus corresponds for example to a land vehicle, for example an automobile, a van, that is to say any vehicle having a door or a trunk hatch.

The vehicle 10 is equipped with a manual or motorized door opening/closing system 101.

In a manual system, the opening and closing movements of the door 101 are possible with manual intervention by an operator. The opening and closing are for example assisted by one or more cylinders connecting the body of the vehicle 10 to the door 101.

In a motorized system, the opening and closing movements of the door 101 are possible without manual intervention by an operator, when the motorized opening/closing function of the door 101 is activated.

A motorized door opening/closing system 101 comprises for example one or more cylinders (for example two cylinders), each cylinder 102 comprising for example an electric motor driving the movable rod of the cylinder in translation. The body of each cylinder is for example fixedly connected via one of its ends to the body of the vehicle 10 while the free end of the rod emerging from the body of the cylinder is connected to the door 101. The translation drive of the rod of each cylinder by the associated motor thus makes it possible to control the closing or opening of the door 101 depending on the direction of translation of the rod. The rod corresponds for example to a threaded rod of the endless screw type, the electric motor of the cylinder comprising the rod driving the endless screw in rotation according to a determined driving torque, which generates a translation movement of the rod relative to to the cylinder body. The motorized opening/closing system of the door 101 also includes a control circuit driving, controlling or controlling each electric motor of each cylinder. The motorized opening/closing system of the door 101 also includes an electronic computer, for example of the ECU type (from the English “Electronic Control Unit” or in French “Unité de Commande Electronique”), for example called a BCM calculator ( Motorized Trunk Box). The ECU and the control circuit of the electric motor(s) are for example included in a single hardware device or form two distinct hardware devices connected to each other via a data bus.

In the manual system or in the motorized system, unlocking the door 101, when the latter is in a closed state, triggers the opening of the door 101. The unlocking is for example controlled by pressing a control button, by example a control button provided in the passenger compartment of the vehicle 10, a button or a control lever provided on the door 101 outside the vehicle 10 and/or a control button provided on a hands-free key of a system Access and Hands-Free Starting (ADML, or PEPS in English for “Passive Entry Passive Start”) of the vehicle 10. Pressing such a button triggers the unlocking of an electrically assisted lock configured to lock the door 101 of the trunk 102 when the door 101 is in the closed position, preventing any access to the trunk 102.

The box 102 is designed and adapted to receive one or more objects or packages. 3 objects 11, 12, 13 are represented on the by way of illustration and not limitation, the number of objects in the trunk 102 being arbitrary, for example limited by the loading volume of the trunk and the volume of the object(s) transported.

A set of sensors comprising one or more sensors 103 are arranged in the trunk 102 of the vehicle 10.

According to a first embodiment, the set of sensors 103 comprises one or more cameras whose field of vision includes the interior of the trunk 102 or part of the interior space of the trunk 102. For example, one or more cameras are arranged in the trunk 102 so as to acquire images of a space comprising the rear part of the trunk up to the interior wall (or face) 1010 of the door 101 of the trunk 102. The interior wall (or interior face) 1010 of the door corresponds to the wall visible from the interior or the passenger compartment of the vehicle, as opposed to the exterior wall of the door 101 which corresponds to the face exposed to the exterior environment of the vehicle 10. Such a camera 103 is then configured for the acquisition of images of one or more objects coming into contact with the interior wall 1010 of the door, this or these objects being likely to fall when the door 101 of the trunk 102 is opened.

According to a variant, one or more of the cameras of the set of sensors correspond to a depth camera or include a depth sensor in addition to a photosensitive sensor.

According to a second embodiment, the set of sensors 103 comprises one or more wave object detection sensors, for example one or more radars and/or one or more LIDARs (from the English “Light Detection And Ranging”). , or “Detection and estimation of distance by light” in French).

A millimeter wave radar is adapted to emit electromagnetic waves and to receive the echoes of these waves returned by one or more objects, with the aim of detecting this or these objects and their distances from the radar. Analyzing data received from a radar over a time interval makes it possible to determine whether an object is moving, the distance between the object and the radar varying over time when the object is moving.

A LIDAR sensor corresponds to an optoelectronic system composed of a laser transmitter device, a receiver device including a light collector (to collect the part of the light radiation emitted by the transmitter and reflected by any object located in the path of the rays light emitted by the transmitter) and a photodetector which transforms the collected light into an electrical signal. A LIDAR sensor thus makes it possible to detect the presence of objects located in the emitted light beam and to measure the distance between the sensor and each detected object. As with radar, analyzing data received from a LIDAR over a time interval makes it possible to determine whether an object is moving, the distance between the object and the LIDAR varying over time when the object is in motion. movement.

Each object detection sensor 103 is arranged in the trunk in such a way that the wave radiation is oriented towards the interior of the trunk 102, for example towards the rear middle of the trunk 102, in front of the interior wall 1010 of the door 101 so as to detect any object moving towards the space between the rear of the trunk 102 and the interior wall 1010, so as to detect an object falling or likely to fall from the trunk when the door 101 is opened.

According to a third embodiment, the set of sensors 103 comprises one or more pressure sensors arranged on the interior wall 1010 of the door 101. A pressure sensor is configured to measure the pressure or the weight exerted by an object when it rests or presses on the sensor.

The pressure sensor(s) form, for example, a grid of sensors arranged on the interior face of the door. According to a variant, a single sensor forming a surface covering all or part of the interior face 1010 of the door is arranged on the interior wall of the door 1010.

The data obtained from such a pressure sensor makes it possible to determine that one or more objects included in the trunk are resting on the door 101 and likely to fall when the door 101 is opened.

According to a fourth embodiment, the set of sensors 103 comprises a sensor configured to measure the torque generated by an electric motor controlling the opening of the door 101 when the door opening/closing system is motorized.

The torque thus measured is for example compared to a reference torque value (which corresponds for example to the nominal torque supplied by the motor to open the door 101). When a difference appears between the torque measured by the sensor and the reference torque, or when this difference is greater than a threshold, this is representative of the presence of one or more objects in the trunk pressing on the door and disturbing the door. opening. This or these supporting objects are then likely to fall from the box 102.

The exemplary embodiments described above with reference to different sensors 103 that can be implemented can be combined in all possible combinations. For example, sensor set 103 includes a camera and one or more pressure sensors, or sensor set 103 includes one or more object detection sensors and a torque sensor. A combination of sensors of different types has the advantage of detecting more reliably one or more objects likely to fall when the door is opened.

A process for controlling the opening of the door 101 of the vehicle 10 is advantageously implemented by one or more on-board devices in the vehicle 10, for example by a computer of the on-board system of the vehicle 10.

A hardware example of such a calculator is described with reference to the .

The computer implementing the process is for example connected to each sensor 103 of the set of sensors via a data bus, directly or via a computer controlling one or more sensors 103. The computer is for example also connected to a computer controlling the lock of door 101.

The sensors and computers form, for example, a multiplexed architecture for the production of different services useful for the proper functioning of the vehicle 10 and for assisting the driver and/or passengers of the vehicle in controlling the vehicle 10, for example for detection and monitoring. prevention of falling objects from the trunk 102. The computers communicate and exchange data with each other via one or more computer buses, for example a CAN data bus type communication bus (from the English "Controller"). Area Network” or in French “Réseau de controllers”), CAN FD (from the English “Controller Area Network Flexible Data-Rate” or in French “Réseau de controllers à flow flexible data”), FlexRay (according to the ISO standard 17458), LIN (from the English “Local Interconnect Network” or in French “Réseau interconnectée local”) or Ethernet (according to the ISO/IEC 802-3 standard).

The process is for example implemented when the vehicle 10 is stationary or when the speed of the vehicle 10 is less than a threshold, for example less than 2, 5 or 10 km/h.

In a first operation, a first piece of information representative of a command to open the trunk door 101 is received.

This first information corresponds for example to a value (for example '0' or '1') transmitted by the computer controlling the lock when unlocking of the lock is activated, for example following an unlocking command received by the computer controlling the lock. lock.

According to another example, the first information corresponds to the data transmitted by the door opening control button 101, these data being received by the computer controlling the lock which transmits them to the computer in charge of the process.

In a second operation, data representative of a detection of the fall of one or more objects included in the box 102 are received, following receipt of the first information. These data are advantageously received from one or more sensors 103.

The acquisition of data by the sensor(s) 103 arranged in the box 102 is for example triggered by the reception of the first information.

According to a variant, the data is acquired by the sensor(s) 103 as soon as the speed of the vehicle 10 falls below a threshold value, for example as soon as the speed of the vehicle 10 becomes less than 10, 5 or 2 km/h.

Data acquisition is for example implemented for a specific duration, for example for 1, 2, 3 or 5 s after triggering data acquisition.

The data are for example acquired at regular time intervals, for example every 50, 100, 200 or 500 ms.

The type of data varies for example depending on the type of sensor 103.

For example, when the sensor 103 corresponds to a camera, the data received correspond to data associated with each pixel of the acquired image(s), for example gray level values coded on for example 8, 10, 12 or more of bits for each color channel, for example RGB (from English “Red, Green, Blue” or in French “Rouge, vert, bleu”). These data make it possible, for example, to determine the successive positions taken by an object 11, 12 or 13 moving in the box 102, by implementing any image processing method known to those skilled in the art. If the camera corresponds to a depth camera or if the camera includes a depth sensor in addition to a video sensor, then the data corresponds to or additionally includes distance information between the sensor and the object(s) 11, 12 , 13 present in the trunk.

The analysis of the image data received makes it possible to detect a displacement or movement of one or more objects over time in the box 102, such a moving object being likely to fall from the box 102 when the box is opened. door 101.

When the sensor 103 corresponds to a radar, the data received correspond to distance data between each object 11 to 13 present in the box 102 and the sensor 103. The analysis of the distance data received makes it possible to detect a variation in distance for one or more objects over time, a variation in distance being representative of an object moving in the trunk 102, such an object being likely to fall from the trunk 102 when the door 101 is opened.

When the sensor 103 corresponds to a pressure sensor, the data correspond to a pressure value exerted by an object on the sensor or to a binary value, with for example '0' indicating that no object is pressing on the sensor 103 and '1' indicating that an object is resting on the sensor 103. The detection of support is for example detected when the pressure measured by the sensor 103 exceeds a determined threshold value. The detection of a support is representative of the detection of a (potential) fall of an object from the trunk 102 when the door 101 is opened.

When the sensor 103 corresponds to a torque sensor, the data received corresponds to one or more torque values. The detection of an object resting on the door 101 is detected when the torque value or values received are different from a torque reference value associated for example with the electric motor controlling the opening and/or with the corresponding phase at the start of the opening movement (for example the torque provided by the motor is greater at the start of opening of door 101 than at the end of opening of door 101).

The measured torque is different from the reference value when an object presses on the door. In fact, either the object 11, 12 or 13 pushes on the door and facilitates opening, the measured torque then being lower than the reference value; either the object 11, 12 or 13 blocks or hinders the opening of the door 101, the measured torque then being greater than the reference value, the motor having to provide a greater torque to try to open the door 101.

A difference between the measured torque and the reference value is representative of one or more objects resting on the door 101, such an object being likely to fall from the box 102 when the door 101 is opened.

According to a variant, the analysis of the data received from one or the other of the sensors includes the determination of a location of the potential fall of an object. The location corresponds for example to information on the area of the trunk 102 (for example left, middle or right).

In a third operation, the opening of door 101 is controlled based on the data received in the second operation.

Such control includes the implementation, automatically by the computer in charge of the process, of one or more actions accompanying the opening of the door (manual or motorized) when the data received is representative of the detection of the fall (potential) of one or more objects from the chest 102 when the door 101 is opened.

The action(s) implemented correspond to:

- a generation of an alert representative of the detection of falling object, such an alert corresponding to an audio alert (rendered via one or more speakers of the vehicle 10 for example) and/or to a light alert (rendered via a dedicated light source or via a light source such as headlights or indicators). The sound alert corresponds for example to a beep, which is for example located on the side where the object is likely to fall. According to another example, the sound alert corresponds to a voice message rendered by voice synthesis. The light alert corresponds, for example, to switching on the indicators with a particular light intensity and/or a variation in the determined intensity. According to another example, additional LED strip type lighting is provided on the trunk, this additional lighting being activated, with for example a particular temporal or amplitude modulation, when the potential fall of an object is detected; and or

- a transmission of a second piece of information representative of a command to block the opening of the trunk door, in particular when the opening/closing system of the door 101 is motorized. Such second information is for example included in a request generated by the computer in charge of the process and transmitted to the computer controlling the motorized opening/closing system to interrupt the opening of the door 101, an ad hoc command being transmitted to the motor electric controlling the opening.

The generation and rendering of the alert make it possible to warn the person who ordered the opening of the door 101 that one or more objects 11 to 13 are likely to fall from the trunk, the person can then interrupt the opening (manually when the opening is controlled manually or by pressing a control button when the opening is motorized).

The automatic blocking of the opening by the transmission of the second information also makes it possible to avoid a fall without intervention by the person who ordered the opening of the door 101.

When the opening is blocked automatically by command from the computer, a new press on the control button triggering the motorized opening of the trunk is required for the opening to continue.
