  • the predetermined positions can be provided to the personnel in charge directly from the car manufacturers, thus ensuring the reliability and accuracy thereof
  • the phase of repairing is carried out when the position of the auxiliary reference points P is substantially different from their respective predetermined positions and is not carried out when the position of the auxiliary reference points P is substantially corresponding to their respective predetermined positions.
  • the fact of analyzing the location of the auxiliary reference points makes it possible to preliminarily determine whether the chassis of the motor vehicle V is damaged to the extent that it requires repair (and, therefore, to implement the phase of repairing), or whether, on the contrary, the damage suffered by the motor vehicle V does not require that the chassis be repaired (and, therefore, that the phase of repairing be implemented).
  • the phase of analyzing allows the process of identifying and estimating the damage suffered by the motor vehicle itself to be significantly accelerated, while also lowering the associated costs.
  • the personnel in charge should not perform any work on the motor vehicle V in case of matching the auxiliary reference points P with the predetermined positions, thus lowering the probability of unintentional damage to the coverings of the motor vehicle V. That being said, it is specified that some of the predetermined positions are where at least one sensor S of the motor vehicle V is located and identify a common plane of lying G.
  • the term “sensor” specifically refers to the face visible from the outside (see Figures 3 and 4 in this regard) of the position sensors typically employed on modem motor vehicles and usually arranged at their bumpers.
  • the fact of detecting comprises at least one step of verifying the belonging of the corresponding auxiliary reference points P to the plane of lying G.
  • sensors S are components of the motor vehicle V which are particularly sensitive to impacts and the proper functionality of which can, therefore, be altered in the face of even minor impacts.
  • the fact of verifying comprises at least one step of acquiring a plurality of first auxiliary reference points Pl on the sensor S and a plurality of second auxiliary reference points P2 in an area A surrounding the sensor S.
  • At least one of the first auxiliary reference points Pl is misaligned from the other first auxiliary reference points Pl; and/or at least one of the second auxiliary reference points P2 is misaligned from the other second auxiliary reference points P2.

  • the present invention also relates to a system 1 for the identification and repair of structural damage in crashed motor vehicles, illustrated by way of example in Figure 1.
  • the system 1 comprises, first of all, at least one measuring device 2 adapted to detect the position of a plurality of auxiliary reference points P placed where an overbody O is located of a crashed motor vehicle V placed on the ground.
  • the measuring device 2 comprises at least one supporting base 3 for resting on the ground and at least one measuring arm 4 associated with the supporting base 3 in a movable maimer.
  • the measuring arm 4 is associated in a rotatable manner with the supporting base 3, e.g. by providing special joints positioned between the two.
  • the measuring device 2 comprises movement means 5 onto the ground associated with the supporting base 3.
  • the movement means 5 comprise, in turn, a plurality of wheels 5 a or of functionally similar bodies that enable the transportation of the measuring device 2.
  • the fact of providing movement means 5 associated with the supporting base 3 enables the use of the measuring device 2 with particular profit, thus allowing, in particular, the easy and intuitive movement thereof for the acquisition of the auxiliary reference points P.
  • the measuring arm 4 conveniently comprises a plurality of rigid bodies 4a having an elongated conformation and mutually connected where their own ends are located.
  • Each rigid body 4a is associated in a rotatable manner with adjacent rigid bodies 4a, such as by means of the interposition of special joints.
  • the measuring arm 4 preferably comprises at least one distal end 4b adapted to be placed in contact with the auxiliary reference points P.
  • the distal end has a substantially rounded conformation.
  • Such a conformation of the distal end 4b proves to be particularly effective in performing the acquisition step with high accuracy, thus allowing the personnel in charge to accurately determine whether the position of the sensor S differs even slightly from the correct one.
  • the distal end 4b has a pointed/conical conformation.
  • this verification mode makes it possible to assess rather quickly whether the sensor S has been damaged and whether, therefore, repair measures aimed at restoring the proper functionality thereof are necessary.
  • the distal end 4b is, therefore, deputed to acquire the measurements that, when processed, allow the state of the crashed motor vehicle V to be determined.
  • the system 1 comprises at least one electronic unit 6 connected to the measuring device 2 and programmed with a plurality of predetermined positions of the auxiliary reference points P on the overbody O.
  • the electronic unit 6 is configured to: compare the position of the auxiliary reference points P with the respective predetermined positions; and to return a first/second result depending on whether the position of each of the auxiliary reference points P is substantially different/corresponding from/to the respective predetermined position and whether the chassis of the motor vehicle V should/should not be repaired.
  • the predetermined positions can be directly provided by the car manufacturers and then uploaded into the electronic unit 6; in this way, the personnel in charge are assured of the correctness of the predetermined positions themselves and can, therefore, determine with certainty whether the position occupied by the auxiliary reference points P is correct or not.
  • the electronic unit 6 returns the second result, then the auxiliary reference points P are substantially where the predetermined positions are located and the phase of repairing may, therefore, not be carried out.
  • the special expedient of analyzing the position of the auxiliary reference points with respect to the predetermined positions makes it possible to determine whether the motor vehicle has suffered any structural damage that requires further inspection and possible repair, or whether, on the contrary, the damage received by the motor vehicle does not require adjusting the chassis.
  • this expedient makes it possible to greatly expedite the diagnosis of damage sustained by the motor vehicle as well as to lower the associated costs.
