Patent ID: 8538724

Claim:
An apparatus ( 1 ) for checking the attitude of a vehicle ( 2 ), comprising: at least one target ( 3 a ) defining a spatial reference system; a mobile unit ( 4 ) equipped with measuring means ( 10 ), for measuring the value of parameters representing the geometric characteristics of a vehicle ( 2 ) wheel ( 9 ) and its position relative to the mobile unit ( 4 ), and with means ( 11 ) for viewing the at least one target ( 3 ); a processor ( 13 ) connected to the measuring means ( 10 ) and to the viewing means ( 11 ) for calculating the position and orientation of the wheel ( 9 ) relative to the spatial reference system and to obtain characteristic parameter values for the attitude of the vehicle ( 2 ); an interface ( 23 ) associated with the mobile unit ( 4 ) and designed to make available in real time to the user manually driving the mobile unit ( 4 ) information relating to the position of the measuring means ( 10 ) relative to the wheel ( 9 ), whereby a user is allowed to manually drive the mobile unit ( 4 ) and to position it in the proximity of the wheel ( 9 ) according to said information, wherein the mobile unit ( 4 ) comprises a trolley ( 5 ) equipped with handles or handgrips to make it easier for the user to manually guide the trolley ( 5 ) to the desired position in front of the vehicle wheel ( 9 ), and wherein said interface ( 23 ) comprises a display mounted on the trolley ( 5 ).
