Definitions
- Motor vehicle comprising an ADAS system coupled to an augmented reality display system of said vehicle.
- the present invention generally relates to the driving assistance systems also designated by ADAS (English acronym for Advanced Driver-Assistance System) fitted to certain motor vehicles.
- ADAS American acronym for Advanced Driver-Assistance System
- It relates more particularly to a motor vehicle comprising an ADAS system coupled to an augmented reality display system of said vehicle.
- ADAS systems are generally associated with systems for displaying visual information on a display medium present in the field of vision of the driver of the vehicle and in particular, on the windshield of the vehicle. This information is intended for the driver of the vehicle to help him guide the vehicle in its road environment.
- This information is complementary to the basic information presented in particular on the dashboard or on a screen present in the cockpit of the vehicle, in order to improve safety, comfort or navigation.
- augmented reality can present on the windshield which serves as a support or screen for the information, safety information such as a reminder of the signs on the road followed, better visualization of the road at night, materialization at the floor of the routes to follow, ...
- VTH an acronym for "Head Up Display” or HUD in Anglo-Saxon terminology for “Head Up Display”
- HUD Head Up Display
- New generations of so-called “long distance” HUDs make it possible to project images further on the road scene extending to the front of the vehicle (up to 10 m or even more) in order to "superimpose”” virtual" graphic elements on the "real" road scene and to offer an augmented reality service.
- the interest of augmented reality is to be able to superimpose on the road scene taking place in front of the vehicle, floating virtual arrows, a track on the ground or a heading/compass, or any other guidance information indicating the road to follow and/or pointing the direction of the road to follow.
- an augmented reality display system generally cooperates with an on-board ADAS system which uses maps, in particular high definition, and data delivered by sensors on board the vehicle, in particular a multifunction camera which is positioned against the windscreen of the vehicle, at the level of the interior mirror.
- Vehicles equipped with a multifunction camera generally include means of recognizing road signs.
- the images captured by the multifunction camera are processed by software means specialized in the recognition of traffic signs, and which then make the link between the sign that the vehicle has just passed and those present in its database.
- a vehicle display system coupled to the ADAS system then displays the panel thus recognized on the vehicle's instrument panel.
- Recognized signs include speed limit signs, no-entry signs and signs prohibiting turning left or right; these signs indicating to the driver of the vehicle which lanes are prohibited to traffic.
- document US10336190A discloses a method for displaying signs recognized by a sign-reading device, in particular a no-entry sign or a stop sign.
- the present invention proposes an augmented reality display solution of prohibited traffic lane signaling information for the vehicle which is adaptive and intuitive for the driver of the vehicle.
- the present invention has as its first object, a motor vehicle comprising a driving assistance system, and an augmented reality display system coupled to the driving assistance system, said display system displaying in an augmented reality window in the field of vision of the driver of the vehicle, a determined graphic, representative of real information indicating a prohibited lane for the vehicle; the format and position of the graphics in the window being adapted according to the distance between the vehicle and the actual prohibited lane signaling information.
- the driving assistance system includes at least one multifunction camera and high-definition mapping; the driving assistance system receiving information delivered by an activation sensor of a direction change indicator of the vehicle and by a sensor for measuring the angle of rotation of the steering wheel of the vehicle; said sensors being embedded in the vehicle.
- the actual prohibited lane signaling information is a no-entry sign and/or a sign prohibiting turning to the right or to the left.
- the second object of the present invention is a method for activating the augmented reality display system, implemented by the vehicle as described above, characterized in that it consists of:
- the augmented reality display system displays in the augmented reality window, the graphics representative of all the prohibited routes present identified; - in a second stage, from a distance of 30 m up to the junction of the prohibited lane with the vehicle's traffic lane then, if an activation of the direction change indicator is detected by the driving assistance, the augmented reality display system displays a graphic superimposed on the junction otherwise, in the absence of activation of the turn indicator to the left or to the right, and if an entry into a prohibited lane is identified or detected by the driver assistance system, from a recognition of the actual signaling information of the prohibited lane and/or from a map coupled with a rotation angle measurement of the steering wheel of the vehicle, then the augmented reality display system displays
- the real prohibited lane signaling information is a no-entry sign and the augmented reality display system displays the graphics of the no-entry sign in the open field, then the graphic representation of the no-entry sign is displayed in perspective in the window, so that seen from the driver, the no-entry sign does not completely obscure the driver's field of vision.
- the present invention has as its third and final object, a computer program product comprising instructions for the execution of the steps of the method as described above.
- Augmented reality makes it possible to anticipate a driving action on the part of the driver, in particular to avoid entering areas prohibited to traffic, in particular one-way lanes which are numerous in urban areas.
- Augmented reality simplifies the driver's mental workload and decision-making when choosing which lane or which lane to avoid.
- FIG. 1 illustrates a block diagram of a vehicle according to the invention
- FIG. 2 illustrates a flowchart for activating the vehicle's augmented reality display system according to the invention.
- window is meant the area of the windshield on which the graphic information delivered by an augmented reality system on board the vehicle is displayed.
- the window is located in the driver's field of vision.
- the dimensions of the window available in which it is possible to actually superimpose graphic elements on real objects of the road scene are not infinite: they are constrained in particular by the size of the optical system which is integrated in the dashboard and which is used to generate the window.
- a window which is generally rectangular in shape, are therefore limited.
- a window is characterized by a determined maximum width and depth of field in augmented reality, also designated by “Field of View” in English terminology.
- the maximum coverage in depth of field of an augmented reality window is between 20 and 80 m in front of the vehicle; the window is centered on the vehicle's traffic lane which passes in front of the vehicle and which the driver sees.
- This coverage also considers the side lanes adjacent to the vehicle's traffic lane but with a more limited depth of field, typically between 40 and 80 m.
- the rectangle is superimposed on the traffic lanes which take place in front of the vehicle and which, due to the perspective effect, defines the portion of the traffic lane of the vehicle as a trapezoid rectangle inscribed in the window while being centered on the window; the lower edge of the rectangle therefore of the window, corresponding to the large side of the trapezium.
- This object can be, for example, a warning information sign, in particular a sign prohibiting the use of the adjacent lane or another lane prohibited for traffic at an intersection.
- FIG. 1 schematically illustrates in the form of a block diagram, a motor vehicle 100 according to the invention comprising an ADAS driving assistance system 10, and an augmented reality display system 20 coupled to the ADAS system
- the display system 20 displays in an augmented reality window 30 on the windshield 40 of the vehicle 100 in the field of vision of the driver 50 of the vehicle 100, an alert information graphic 60 determined and evolving according to the distance between the vehicle 100 and real signaling information of a lane prohibited to traffic for the vehicle 100; the format and position of the graphics 60 in the window 30 being adapted according to the distance between the vehicle 100 and the actual signaling information, not shown.
- the ADAS system 10 comprises at least one multifunction camera 11 and a high-definition map 12. It also receives information delivered by an activation sensor of the direction change indicators 70 of the vehicle and by a sensor 80 for measuring the vehicle steering wheel rotation angle 100; said sensors 70 and 80 being on board the vehicle 100.
- the ADAS system 10 further comprises means for recognizing panels 13 of the vehicle from the images captured by the multifunction camera
- the present invention considers three situations in which the vehicle 100 according to the invention can be confronted during a journey, preferably but not exclusively, in an urban area, and which are compatible with the performance of an augmented reality display system (Window available in augmented reality).
- Window available in augmented reality augmented reality
- the ADAS system 10 of the vehicle 100 identifies the lanes prohibited to the vehicle 100, at an average distance of between 80 and 100 m in front of the vehicle 100.
- the augmented reality display system 20 of the vehicle 100 displays in the window 30, in a systematic way, a simple and uncluttered graphics 60 locating the forbidden ways (in real superimposition of the forbidden way).
- the ADAS system 10 identifies the prohibited lanes at a short distance of between 20 and 30 m in front of the vehicle 100.
- the augmented reality display system 20 of the vehicle 100 displays in the window 30 a graphic design adapted to the situation, for example, a graphic 60 representing a red cross on one of the side edges of the window 30 or a sign prohibiting turning right or left if the turn indicator (flashing) 70 is activated in the direction of the forbidden lane.
- the ADAS system 10 identifies that the vehicle 100 is already in the prohibited lane or about to be there.
- the augmented reality display system 20 of the vehicle 100 displays a graphic 60 in the open field in the window 30, facing the driver 50.
- the graphic representation (graphics) 60 is adapted and scalable from a simple lateralized indication of a prohibited lane to a copy of the "no entry" sign in large size facing the driver 50.
- the graphic representation of the large no-entry sign is displayed in perspective in the window 30, so that seen from the driver, the latter does not completely mask the field of vision of the driver 50.
- a first step, 200 as soon as at least one no-entry sign has been detected or identified by the map 12 or a "no left or right turn" sign has been recognized by the recognition means of panels 13 of the vehicle 100, has a distance between the prohibited lane and the vehicle of between 100 m and 50 m, then the augmented reality display system 20 displays in the augmented reality window 30, the graphics 60 representative of all the forbidden ways present in the window.
- a second step, 201 from a distance of 30 m up to the junction of the prohibited lane with the vehicle traffic lane (the prohibited lane is not visible in the augmented reality window) then , if an activation of the direction change indicator (flashing) 70 is detected by the ADAS system 10 then the augmented reality display system 20 displays a determined graphic 60 superimposed with the junction.
- the augmented reality display system 20 displays the representative graphics 60 of a no-entry sign in the open field in the driver's field of vision 50.
- the display activation method implements a computer generated program with instructions for performing the steps of the method described above.
- This program is implemented by one or more processors of the vehicle's ADAS system (ADAS supervisor) in conjunction with one or more processors of the IVI (In-Vehicle Infotainment) system, which is the vehicle's central unit dedicated to data processing and communication with the driver.
- ADAS supervisor ADAS supervisor
- IVI Intelligent Vehicle Infotainment
- Such a program can be updated with the possibility of adding functions by using an update by OTA "Over The Air” type waves.
