- the control of the opening of one or more doors (also called opening or doors) of a vehicle comprising one or more object detection sensors (for example one or more radars and/or one or more cameras) comprises the detection of the opening of a door of the vehicle according to a first opening position.
- the first opening position is for example defined by a first opening angle, for example equal to a few degrees or a few tens of degrees maximum.
- the detection of the opening of the door is advantageously associated with the determination of the presence of an object (for example a bicycle, a motorcycle, a scooter or a car) in the vicinity of the vehicle, that is to say approaching the vehicle (for example from the rear), such presence or absence of an object being determined from data received from the object detection sensor(s) fitted to the vehicle.
- a door opening blocking system fitted to the vehicle is advantageously controlled according to the result of the determination of the presence (or absence) of an object approaching the vehicle to authorize or prohibit the opening of the door from the first open position to a second open position.
- the second opening position is defined by a second opening angle whose value is greater than the first opening angle.
- the control of a door opening blocking system makes it possible to block the opening of the door in an opening position presenting a danger for the approaching object, increasing the safety of road users in the environment close to the vehicle, in particular users approaching the vehicle who could collide with the door if the latter were fully open.
- FIG. 1 schematically illustrates a vehicle 10 in a road environment, according to a particular and non-limiting embodiment of the present invention.
- the vehicle 10 corresponds for example to a vehicle with a heat engine, an electric vehicle or a hybrid vehicle (combining heat engine and electric motor).
- the vehicle 10 also corresponds to a land motor vehicle, for example a motor vehicle, a truck or a bus.
- the vehicle 10 is parked on the edge of the roadway of a traffic lane, for example to the right of the roadway in the direction of traffic.
- the vehicle 10 is parked to the left of the roadway in the direction of traffic, for example on a one-way traffic road.
- the implementation example described with reference to FIG. 1 corresponds to the control of the opening of a left door 101 of the vehicle 10, for example the left rear door 101.
- the invention applies from same way to the opening control of each of the doors of the vehicle 10, that is to say the left front door (or driver's door), the left rear door, the right front door and/or the right rear door.
- the opening control as described in the present description applies to only part of the doors of the vehicle 10.
- a door is also called a door and corresponds to the opening and closing device allowing the descent and the ascent of the driver and/or passenger(s) in the vehicle 10.
- a door opens from inside the vehicle or from outside the vehicle 10, for example by means of a handle.
- the invention as described in the present description applies advantageously when the driver or a passenger tries to open the door 101 from inside the vehicle 10.
- the invention also relates to a door opening control 101 when the driver or a passenger tries to open the door 101 from outside the vehicle 10.
- the vehicle 10 advantageously embeds one or more object detection sensors, for example one or more sensors of different types or of different natures.
- This or these object detection sensors correspond for example to sensors of one or more driving assistance systems, called ADAS (from the English "Advanced Driver-Assistance System” or in French “Système d'aide to advanced driving”).
- ADAS Advanced Driver-Assistance System
- This or these sensors are advantageously configured to supply a set of information to the ADAS systems of the vehicle 10 on the environment of the vehicle 10, in particular on the presence of moving or fixed objects in the environment of the vehicle 10, for example another vehicle, a bicycle, a motorcycle, a moped, a scooter, a pedestrian, etc.
- the sensor(s) associated with these object detection systems correspond, for example, to one or more of the following sensors:
- One or more millimeter wave radars 102 arranged on the vehicle 10, for example at the front, at the rear, on each front/rear corner of the vehicle 10; each 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 obstacles and their distances vis-à-vis the vehicle 10; and or
- a LIDAR sensor corresponding to an optoelectronic system composed of a laser transmitter device, a receiver device comprising a light collector (to collect the part of the light radiation emitted by the emitter and reflected by any object located on the path of the light rays emitted by the emitter) 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 light beam emitted and to measure the distance between the sensor and each object detected; and or
- one or more cameras associated or not with a depth sensor for the acquisition of one or more images of the environment around the vehicle 10 located in the field of vision of the camera or cameras;
- one or more blind spot detectors corresponding for example to a millimeter wave radar, a sonar or a camera.
- the data, or types of data, obtained from this or these sensors vary according to the type of sensor.
- the first data correspond for example to distance data between points of the detected object and the sensor.
- Each detected object is thus represented by a cloud of points (each point corresponding to a point of the object receiving the radiation emitted by the sensor and reflecting at least part of this radiation), the cloud of points representing the envelope (or a part of the envelope) of the detected object as seen by the sensor and ultimately by the vehicle 10 carrying the sensor.
- the first data correspond to data associated with each pixel of the acquired image or images, for example gray level values coded on for example 8, 10, 12 or more bits for each color channel, for example RGB (from English “Red, Green, Blue” or in French “Rouge, vert, blue”).
- the sensor(s) are for example associated with one or more of the following ADAS systems: - parking assistance system; and or
- BLIS from the English “Blind spot Information System” or in French “system of information from blind spot”
- BSM from the English “Blind Spot Monitoring” or in French “surveillance of dead angle”
- ACC Adaptive Cruise Control
- the vehicle 10 advantageously embeds one or more door opening blocking systems, for example one door opening blocking system per door whose opening is controllable, that is to say whose opening can be permitted or prohibited (or blocked) by the control of the blocking system.
- a door opening blocking system is described with reference to Figures 3 and 4.
- a process for controlling the opening of a door of the vehicle 10, for example the door 101, is advantageously implemented by a computer or a set of computers of the on-board system of the vehicle 10.
- the opening of door 101 is detected.
- An opening of the door is advantageously detected when the door 101 opens according to a first open position.
- the first opening position corresponds to an opening of the door according to a first opening angle, called a-i.
- This first opening angle advantageously corresponds to an angle less than a threshold, for example to an angle less than 5, 10 or 15°.
- the detection of the opening of the door 101 is for example obtained from a door opening sensor associated with the door 101, such a sensor transmitting a signal to the computer in charge of controlling the opening of the door. when an opening of door 101 is detected.
- An opening angle corresponds to an angle formed between a longitudinal axis of the vehicle 10 and a longitudinal axis of the door 101.
- the presence of an object approaching the vehicle is sought or determined.
- a determination is advantageously obtained at from data received from one or more object detection sensors, for example data received from one or more radars 102 and/or data received from one or more cameras (not illustrated in FIG. 1).
- the analysis of the data received from this or these sensors makes it possible to determine whether an object, for example a bicycle 11 as in the example of FIG. 1, is present or not in the spatial zone covered by this or these sensors.
- the analysis of these received data thus makes it possible to determine whether an object such as the bicycle 11 is approaching the vehicle 10, for example from behind and/or from the front of the vehicle 10, depending on the area covered by the the sensors providing the data.
- the determination of the presence or absence of an object is obtained from data received from a single sensor or from several sensors of the same type or of the same nature, by example from the data received from one or more radars 102.
- the determination of the presence or absence of an object is obtained from data received from sensors of different natures or of different types, for example from data received from one or more radars 102 and data received from a camera, for example a reversing camera of the vehicle 10.
- the determination of the presence or absence of an object is obtained from data received from one or more radars and data received from a blind spot detector arranged on or at the level of an exterior mirror of the vehicle.
- the determination of the presence or absence of an object is obtained from data received from one or more radars, from data received from a camera and from data received from a detector of blind spot arranged on or at the level of an exterior mirror of the vehicle 10.
- a fusion of the data received from the various sensors is carried out before determining whether or not an object is present in the zone covered by these sensors.
- Such a fusion makes it possible to aggregate data of different natures, relating to the same spatial zone, to refine the result of the detection of the presence of an object or to improve detection by increasing, for example, the confidence associated with the determination.
- the presence of a bicycle 11 approaching the vehicle 10 is determined during this second operation, for example from the data received from a rear left radar 102, or from the merged data received from left rear radar 102 and rear view camera (not shown).
- a door opening blocking system 101 such as system 3 of FIGS. 3 and 4, is checked according to the result of the determination implemented in the second operation.
- Such a door opening blocking system is advantageously configured to block or authorize the opening of the door 101 from the first position to a second opening position, the second opening position corresponding to an opening of the door according to a second opening angle greater than the first opening angle a-i.
- the blocking system is controlled so as to block (or prevent or prohibit) the opening of the door 101 to the second open position.
- the door 101 is thus blocked in the first open position so as not to encroach on the roadway and not to cause a collision with the object approaching the vehicle 10.
- Such a scenario corresponds to that illustrated by the Figure 1, according to which a bicycle 11 is detected approaching the vehicle 10, the door 101 then being blocked in the first open position by the door opening blocking system 101.
- the blocking system is then in a position or state of blocking or prevention of opening, such a state being illustrated by figure 4.
- the blocking system is controlled so as to authorize (or release) the opening of the door 101 towards the second opening position, that is that is to say to authorize an opening of the door 101 greater than that corresponding to the first opening position.
- the complete opening of the door 101 is authorized to allow a passenger of the vehicle 10 to leaving the vehicle 10 (or entering it, if applicable).
- Such a scenario corresponds to the example illustrated in figure 2.
- the process further comprises an operation of detecting a force applied to the door 101 after the first operation, that is to say after the detection of the opening of the door 101 in the first open position.
- the detection of the application of an opening force on the door 101 triggers the second operation corresponding to the determination of the presence (or absence) of an object approaching the vehicle 10.
- the opening blocking system is controlled so as to block the opening of the door 101 and prevent the opening of the door towards the second opening position when:
- a presence of an object 11 approaching the vehicle is determined; and - a force applied to the door 101 is detected.
- FIG. 2 schematically illustrates the vehicle 10 in its road environment, according to another particular and non-limiting embodiment of the present invention.
- figure 2 illustrates the absence of an object approaching the vehicle 10 during the second operation of the process described above with regard to figure 1.
- the door 101 opening blocking system is released so as to allow a greater opening of the door 101, that is to say a passage of the door 101 from the first opening position to a second opening position in which the opening angle of the door, called the second opening angle a 2 , is greater than the first opening angle cq (a 2 > ai).
- the second opening angle advantageously corresponds to an angle greater than the threshold defined above with regard to FIG. 1. No object approaching the vehicle 10 being detected, the opening of the door 101 so as to allow a passenger of the vehicle 10 to exit (or enter) is authorized by the blocking system which is then in a position or an open or released state, such a state being illustrated by Figure 3.
- FIG. 3 schematically illustrates a vehicle door opening blocking system 3 of the vehicle 10 in a first configuration, according to a particular and non-limiting embodiment of the present invention.
- FIG. 3 illustrates a door opening blocking system 3 on board the vehicle 10, the control of which makes it possible to authorize or block the opening of the door 101 (and of any door equipped with this system 3).
- System 3 in FIG. 3 corresponds to a so-called ratchet and pawl system.
- a ratchet wheel corresponds to a non-return device comprising a wheel provided on its periphery with notches or teeth.
- the ratchet wheel is associated with a pawl, one end of which is adapted or configured to fit into a notch or between two teeth to block the ratchet wheel in one of the directions of rotation of the wheel.
- the system 3 comprises two ratchet wheels 301, 302 identical and aligned coaxially along an axis of rotation 303 which advantageously corresponds to the axis of rotation of the door 101 with respect to the structure.
- the ratchet wheels 301, 302 are in recessed connection with the door 101.
- the ratchet wheels 301, 302 are advantageously arranged at a determined distance from each other.
- the system 3 also comprises two pawls 31, 32 cooperating respectively with the ratchet wheels 301, 302.
- the pawl 31 is provided to block the rotation of the ratchet wheel 301 when the pawl 31 is in a blocking position and the pawl 32 is provided to lock the rotation of the ratchet wheel 302 when the pawl 32 is in a locking position.
- the pawl 31 and the pawl 32 are fixed on a shaft or an axis 33 and arranged at a determined distance from each other corresponding to the distance provided between the ratchet wheels 301, 302.
- the ratchet wheel 301 and the pawl 31 are aligned in the transverse plane so that the pawl 31 can cooperate with the ratchet wheel
- FIG. 3 shows the system 3 in a non-blocking or release position allowing the free rotation of the ratchet wheels 301, 302 vis-à-vis the pawls 31, 32, that is to say that the pawls 31, 32 are not engaged in the ratchet wheels 301,
- the rotation of the pawls 31, 32 is controlled by controlling the rotation of the axis 33 (around its transverse axis 330), the axis 33 being driven in rotation for example by a servomotor connected to one end of this axis 33
- the servomotor advantageously receives command or control signals from the computer of the vehicle's on-board system 10 in charge of the process for controlling the opening of the door 101 described with reference to FIGS. 1 and 2.
- the invention is not limited to such an example and extends to any number of ratchet wheels, for example 1 wheel ratchet and 1 pawl.
- the locking system is not limited to a ratchet and pawl system but extends to any system, for example a system with chamfered index finger(s) fitting into a groove. of a disk so as to block the rotation of the disk.
- FIG. 4 schematically illustrates the vehicle door opening blocking system 3 of the vehicle 10 in a second configuration, according to a particular and non-limiting embodiment of the present invention.
- Figure 4 illustrates the system 3 in a so-called blocking position to prevent any rotation of the door 101, for example to prevent the door 101 from moving from the first open position to the second open position.
- the passage or the transition from the non-blocking or release position illustrated in FIG. 3 to the blocking position is obtained by driving the axis 33 in rotation around the transverse axis 330 in the anti-clockwise direction illustrated by the arrow 430, this rotation driving the pawls 31, 32 in rotation, the pawls 31, 32 blocking the rotation in the clockwise direction illustrated by the arrow 403 of the ratchet wheels 301, 302 by fitting into the notches or teeth of each wheels 301, 302.
- the clockwise rotation illustrated by the arrow 403 corresponds to the direction of opening rotation of the door 101.
- the shaft or axis 33 is rotated clockwise, driving the pawls 31, 32 in rotation which emerge from the notches or teeth of the ratchet wheels 301, 302 and thus release the ratchet wheels 301, 302 which can again turn freely around their axis of rotation 303.
