Definitions

  • the present invention refers generally to a multifunctional unit for the analysis and calibration of devices and components present in a vehicle and, in particular, in a motor vehicle.
  • the invention relates to a multifunctional unit, which allows solving the problem of replacement, activation, control and calibration of advanced driver assistance systems (A.D.A.S); some specific systems are listed below, as a non-limiting example:
  • the multifunctional unit provides the dialogue with the electronic systems, responsible for the control of the functions listed above through a wireless connection with a device connected to the OBD diagnostic port of the vehicle; this is to allow a dialogue, in the operating phase, between the multifunctional unit and the onboard electronic systems.
  • the multifunction unit is also equipped with a removable display module to proceed with greater convenience to the adjustments to be made.
  • Till now headlight beam setter devices are known to control the orientation and light intensity of the headlights of a motor vehicle.
  • a headlight beam setter device essentially comprises a height-adjustable optical group and mounted on a vertical translatable support, which is aligned with the headlight of the motor vehicle, so as to receive the collimated light beam coming from the headlight, without introducing any distortion during the procedures of translation of the support and/or alignment of the optical group.
  • the above said optical group is formed by a series of lenses suitably shaped in a way to focus the light beam of all types of headlights.
  • the vertical support brings to its top a mirror or a laser alignment system, which allows the alignment of the device with the longitudinal axis of the motor vehicle.
  • the light beam coming from the headlight of the motor vehicle is directed, through a suitable optical preparation path, towards a digital camera integrated in the headlight beam setter module available to the user and the image processed in a specific way and in graphic format shows the exact pointing position and the shape of the light beam, which can then be verified and possibly regulated.
  • the orientation of the vehicle headlight can thus be directed to the correct pointing position.
  • the headlight beam setter devices also include a measuring device of the light beam intensity emitted from both the low beam headlight and high beam headlight of the motor vehicle.
  • the aforesaid devices are designed only for the control and the passive regulation of the headlights, without the possibility of communicating with the control units of the new intelligent optical systems.
  • the object of the present invention is therefore to provide a multifunctional unit for the analysis and calibration of devices and components of a vehicle and in particular of a motor vehicle, which allows to perform various operations of regulation and control of the various systems present in the present vehicles, such as, among others, digital optical group and vehicle driver assistance systems (ADAS systems), using a single multi-purpose structure.
  • ADAS systems digital optical group and vehicle driver assistance systems
  • Another object of the present invention is to provide a multifunctional unit for the analysis and calibration of devices and components of a vehicle, which is able to communicate with the vehicle electronic systems to guarantee a simplification of the repair activities, replacement and regulation, for example of optical groups, cameras, radar and infrared and other sensors; the dialogue with the vehicle takes place through an interface inserted in the OBD socket and connected wirelessly to the multifunctional system, so as to allow the reading of useful data (e.g. tire pressure, steering position, etc.) to the adjustments in progress and to allow the activation of special functions necessary to make the adjustments themselves (e.g. switching on a specific area of the LED matrix of the vehicle headlights, activation of the configuration and learning procedure, etc.).
  • useful data e.g. tire pressure, steering position, etc.
  • special functions necessary to make the adjustments themselves e.g. switching on a specific area of the LED matrix of the vehicle headlights, activation of the configuration and learning procedure, etc.
  • a further object of the present invention is to provide a multifunctional unit for the analysis and calibration of devices and components of a vehicle, which allows proceeding more comfortably to the adjustments to be made, by means of a mobile display unit with wireless connection.
  • 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
  • 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.
  • the multifunctional unit 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.
  • 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 .
  • 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 .
  • a system of pointing and alignment to the vehicle known per se such as a laser alignment system
  • 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 .
  • 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”.
  • 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 .
  • 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.
  • A.D.A.S. systems Advanced Driver Assistance Systems
  • radar infrared sensors
  • the headlight beam setter device 12 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 .
  • 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.
  • 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.
  • 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 .
  • 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.
  • 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.).
  • 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.
