BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

(1) The aforementioned objects and advantages will result to a greater extent from the following description, relating to a preferred embodiment of the multifunctional unit of analysis and calibration, which is the object of the present invention, provided by way of example and by way of non-limiting example, and from the attached drawings, also supplied as indicative and illustrative, but not limitative, in which:

(2) FIG. 1 is a perspective view of a multifunctional unit for the analysis and calibration of devices and components of a vehicle, in use, according to the present invention;

(3) FIGS. 2, 3 and 4 are a series of perspective views of some components of the multi-functional unit of FIG. 1, according to the present invention.

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

(4) With reference to the aforementioned figures, the multifunctional unit according to the invention consists of a movable trolley 10, such that, it can be positioned around a vehicle or motor vehicle 13 frontally placed to the trolley 10, which may have a guide 11 supporting a headlight beam setter device 12 (such that the headlight beam setter device can be easily installed and removed); in the case in which the guide 11 and the headlight beam setter device 12 are used, the aforementioned headlight beam setter 12 is able to translate according to a direction (axis X) transverse with respect to the direction (Y axis) of pointing of the headlight of the vehicle.

(5) In other embodiments of the invention, the guide 11 can also support a reflecting element for the electromagnetic waves, which can replace or be combined with the headlight beam setter device 12.

(6) The movable trolley 10 has a system of pointing and alignment to the vehicle known per se (such as a laser alignment system), in a way that the headlight beam setter device 12 and/or the reflecting element, if present, are adjustable and positionable along the X-axis and the pointing system can be aligned along the Y axis with the left and right headlights of the vehicle 13.

(7) In practice, the laser alignment system makes it possible to adjust and position the movable trolley 10 and, optionally, the headlight beam setter device 12; in this way, when the headlight beam setter 12 is present, the aforementioned headlight beam setter 12 and the trolley 10 are aligned with each other and form a known and defined angle with the vehicle or motor vehicle 13.

(8) This makes it possible to align the entire integral structure with the self-propelled trolley 10 and, in this way, all the objects applied to the trolley 10 may have a defined and verified geometrical position, relative to the rear, front or lateral parts of the vehicle or motor vehicle 13.

(9) A base 14 is positioned above the trolley 10, which supports a screen or panel 15, at the top of which a video projector 16 is placed, suitable for projecting the calibration tables of the cameras used in the driver assistance systems of the various vehicles and, in general, of all the systems that need “target panels”.

(10) In particular, the video projector 16 is of the short-range type with vertically adjustable and angularly adjustable arrangement on at least two positions, so as to project such calibration tables onto screen 15 of the trolley 10 and/or on the floor 17.

(11) The trolley 10 also allows the assembly, in a lateral position, of elements 18 of activation, reference and calibration for the regulation and control of Advanced Driver Assistance Systems (A.D.A.S. systems), such as radar, infrared sensors, etc.

(12) The headlight beam setter device 12, if present, can also be connected to the onboard electronic systems of the vehicle 13 by means of an OBD device 19, installed on board of the vehicle in the OBD diagnostic socket present in the vehicles, which is able to generate univocal data of identification of the vehicle or motor vehicle 13 to be transmitted externally and which is provided with a configurable multiprotocol communication system for bi-directional communication with the electronic systems (control units) installed on board the vehicle or motor vehicle 13.

(13) In particular, the OBD device 19 consents to realize a functional dialogue between the headlight beam setter 12 and the electronic headlight control units of the motor vehicle 13, in order to activate the procedures envisaged for the necessary adjustments.

(14) The connection of the headlight beam setter 12 with the onboard electronic systems therefore enables the headlight beam setter 12 to receive specific information necessary to ensure the correct regulation of the optical groups of the vehicle, such as, for example, by way of example, but not limiting, tire pressure, steering position, battery voltage, etc; in this way, it is possible, for example, to adjust the orientation of the headlight of the motor vehicle 13 automatically, quickly and safely, under ideal conditions.

(15) Still according to the present invention, the headlight beam setter 12 can be equipped with a portable display unit 20 which, at rest, is housed in the headlight beam setter itself, meanwhile, operationally, it can be removed and taken near the engine compartment of the vehicle 13 to proceed more comfortably to the regulations to be made; in this way, in fact, one can have an eye on the effect of the adjustments made on the generation of the light image produced by the headlights of the vehicle 13 and shown on the unit 20.

(16) This opportunity makes it easier and more comfortable, thanks to the mobility of the display unit, all the adjustments and controls of the other A.D.A.S. systems, which are carried out from the passenger compartment of the vehicle 13 and in the driving position.

(17) Thus, using the OBD 19 device, a two-way functional communication takes place between the portable display unit 20 and/or the headlight beam setter device 12 and the electronic control units of the A.D.A.S. systems. in general and in particular of the digital optical groups of the vehicle, in order to activate the procedures required for the necessary adjustments and to ensure a correct configuration, control and regulation procedure of the A.D.A.S. on the vehicle based on additional support parameters such as, for example, vehicle tire pressure, vehicle steering position, battery voltage, etc.

(18) Moreover, according to the invention, the video projector 16 allows to simulate road dynamics, at least for what concerns the functions driven by the cameras of the motor vehicle 13; in practice, the projector 16 allows to project simulation images, such as a video on road or an animation, in order to verify that the alert systems work (for example, for the identification of a passer-by, for the recognition of road signs, etc.).

(19) By virtue of the foregoing, it is understood that the multifunctional unit for the analysis and calibration of devices and components of a vehicle, which is the object of the present invention, achieves the objects and realizes the advantages mentioned.

(20) Finally, it is clear that many other variations may be made to the multifunctional unit in question, without departing from the principles of novelty inherent in the inventive idea expressed herein, as it is clear that, in the practical implementation of the invention, the materials, the shapes and the dimensions of the illustrated details may be any according to the requirements and replaced with other technically equivalent ones.
