Multifunctional unit for the analysis and calibration of devices and components of a vehicle

Abstract

A multifunctional unit for the analysis and calibration of devices and components of a vehicle and, in particular, of a motor vehicle (13), comprising a movable trolley (10) of support; above the trolley (10) there is a base (14), which carries a screen or panel (15), at the top of which a video projector (16) is placed, suitable for projection of the calibration panels used in driver assistance systems of vehicles.

1 . Multifunctional unit for the analysis and calibration of devices and components of a vehicle and, in particular, of a motor vehicle ( 13 ), comprising a moveable trolley ( 10 ) of support, characterized in that, a base ( 14 ) is placed above said trolley ( 10 ), which carries a screen or panel ( 15 ), at the top of which a video projector ( 16 ) is placed, suitable for projecting simulation images and/or graphic images representing panels of calibration used for the regulation and control of driver assistance systems. 
     
     
         2 . Multifunction unit as in  claim 1 , characterized in that said movable trolley ( 10 ) is devoid of a guide ( 11 ), placed parallel to said base ( 14 ), for the support of a headlight beam setter device ( 12 ) and/or of a reflecting element for the electromagnetic waves, adapted to translate in a direction (X) transverse to the direction (Y) for pointing the headlights of a vehicle placed frontally to said movable trolley ( 10 ). 
     
     
         3 . Multifunctional unit according to  claim 1 , characterized in that said movable trolley ( 10 ) has a guide ( 11 ) for supporting a headlight beam setter device ( 12 ) and/or an element reflecting the electromagnetic waves, which is capable of translating in a direction (X) transverse to the direction (Y) of pointing of the headlights of a vehicle placed frontally to said movable trolley ( 10 ) and that, above said guide ( 11 ) of support, a base is placed ( 14 ), which carries a screen or panel ( 15 ), at the top of which a video projector ( 16 ) is placed, suitable for the projection of images of simulation and/or graphic images representing calibration panels used for regulation and control of advanced driver assistance systems ADAS. 
     
     
         4 . Multi-functional unit as in at least one of the previous claims, characterized in that said video projector ( 16 ) is short-range with adjustable disposition on at least two positions, so as to project said calibration panels on said screen ( 15 ) of the trolley ( 10 ) and/or on the ground or on a floor ( 17 ). 
     
     
         5 . Multifunctional unit according to at least one of the previous claims, characterized in that said headlight beam setter device ( 12 ) has a pointing and alignment system to said vehicle, such as a laser alignment system, which allows adjusting and position said headlight beam setter device ( 12 ) and said movable trolley ( 10 ), so that they are aligned with each other and forming a known and defined angle with said vehicle. 
     
     
         6 . Multifunction unit as in at least one of the previous claims, characterized in that said trolley ( 10 ) has lateral fixing systems which support the installation of elements ( 18 ) of activation, reference and calibration for the regulation and control of advanced driver assistance systems ADAS, such as radar and/or infrared sensors. 
     
     
         7 . Multifunctional unit as in at least one of the previous claims, characterized in that it uses a portable display unit ( 20 ) which, when at rest, is housed in the headlight beam setter device ( 12 ), meanwhile operationally, it can be removed and carried near the vehicle to proceed, in a quick and simplified way, to the adjusting to be made, thus displaying directly on said unit ( 20 ) the effect of the adjustments made. 
     
     
         8 . Multifunctional unit as in at least one of the previous claims, characterized in that said portable display unit ( 20 ) and/or said headlight beam setter device ( 12 ) can be connected to the vehicle electronic systems by means of an OBD device ( 19 ).), installed on board of the vehicle in a specific OBD diagnostic socket, so as to allow a two-way functional dialogue between said portable display unit ( 20 ) and/or said 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 envisaged for the necessary adjustments and to guarantee a correct configuration, control and regulation procedure of said A.D.A.S on the vehicle based on additional support parameters, such as, for example, vehicle tire pressure, vehicle steering position and/or battery voltage.
