Problems solved by technology

[0032] In particular, the system described in patent document WO2009056392 has the disadvantage of being complex and expensive, in fact it requires means for enabling the automatic movement of the mobile unit along a predetermined path
[0033] This also entails the other above-mentioned disadvantages, considering that the system can only be used in restricted predetermined areas

Embodiment Construction

[0083] Device 1 includes at least one target 3 ( figure 1 In reference number 3a or 3b), the object 3 defines a spatial reference frame. As known in the prior art, the target 3 comprises, for example, a panel with a surface having optically measurable geometric features.

[0084] The device also comprises a mobile unit 4 which can be positioned manually by a user, ie the operator responsible for checking the attitude of the vehicle 2 .

[0085] The mobile unit 4 preferably comprises a trolley 5 equipped with a plurality of wheels 6 for moving the trolley 5 . At least one wheel 6 is of the rotatable type to make it easier to position the measuring unit.

[0086] It should be noted that the mobile unit 4 comprises a front part 7 (ie, the front of the trolley) and a rear part 8 (ie, the rear of the trolley).

[0087] In view of this, some wheels 6a (two are shown in the example, but they could also be a different number) are rotatably mounted on the trolley 5 frame at the fron...

Abstract

An apparatus (1) for checking the attitude of a vehicle (2) comprises: at least one target (3) 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 wheel (9) of the vehicle (2) 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 reference system and to obtain characteristic parameter values of the attitude of the vehicle (2); an interface (23) designed to make available in real time to the user driving the mobile unit (4) information relating to the position of the measuring means (10) relative to the wheel (9), the mobile unit (4) being able to be driven manually by one user to position it in proximity of (facing) the wheel (9).

Description

technical field [0001] The present invention relates to a device and a method for checking the attitude of a vehicle. Background technique [0002] Examination of vehicle attitude is important to optimize road grip, driving comfort and tire wear. [0003] In fact, road grip and tire wear depend on the adhesion of the vehicle to the road surface, which in turn is mainly due to the following two factors: the contact area of ​​the wheel with the road surface and wheel drift; both of these factors depend on the vehicle's chassis and suspension rack geometry. [0004] The geometry of a vehicle's chassis is precisely defined by characteristic parameters of the vehicle's attitude, including wheel angles, wheel trajectory and slope characteristics, and other parameters such as suspension length. Correct values ​​for these parameters are specified by the vehicle manufacturer and may generally vary according to the type and model of the vehicle. [0005] In view of this, the check ...
