<p>An apparatus (1) for diagnostic assessment of the set-up of a vehicle (2) comprises: two contact tracks (6) for tyres (4) of the vehicle (2) having two stretches adjacent to corresponding optical measuring devices (11), for detecting image information of a pair of front wheels (3) of the vehicle (2) resting on said stretches of the tracks (6) in a first operating position of the vehicle (2); a processing unit (18) programmed to process the image information and calculate a position in space of the front wheels (3) of the vehicle. The processing unit (18) implements a model of operation of a vehicle on the road, and is programmed to calculate: (i) an ideal trajectory of the vehicle (2) being assessed, depending on a type of vehicle set, the position of the front wheels (3) and the model; (ii) an actual trajectory followed by the vehicle (2) being assessed during a movement from the first operating position to a second operating position, in which the rear wheels (3) of the vehicle (2) rest on said stretches of the tracks (6), depending on the type of vehicle, the position detected for the front wheels (3) and further image information relating to at least one predetermined portion of the vehicle (2) and detected at least when it is in the second operating position. The processing unit (18) is programmed to derive diagnostic indications, depending on a deviation of said actual trajectory relative to said ideal trajectory.</p> |
