Embodiment Construction

[0115] Referring to the drawings, reference numeral 1 denotes a device for calibrating ADAS sensors of a vehicle 9 .

[0116] Vehicle 9 is located in maintenance area 8 .

[0117] The device 1 comprises a base unit 2 . The base unit 2 includes a plurality of wheels 20 . Preferably, the base unit 2 comprises at least three wheels 20 . In one embodiment, the base unit 2 comprises at least four wheels 20 .

[0118] The plurality of wheels 20 rotate or are rotatable about respective axes of rotation R1, R2.

[0119] The wheels 20 also rotate about respective axes of rotation A1 , A2 , A3 . The axes of rotation are oriented perpendicular to the respective axes of rotation R1, R2.

[0120] In one embodiment, the base unit comprises (at least one) stabilizing foot movable between a raised position and a lowered position. The stabilizing feet can be moved by hand or by actuators controlled by a person or a processing unit. When the structure is moved, the feet remain in a raise...

Abstract

An apparatus (1) for calibrating an ADAS sensor of a vehicle (9) comprises: a base unit (2) including a plurality of wheels (20); a support structure (3) integral with the base unit (2); a vehicle calibration assistance structure (4), mounted on the support structure (3) and including a calibration device (41, 42) configured to facilitate aligning or calibrating the ADAS sensor; a position detector, configured to capture values of a position parameter representing a position of the support structure (3) relative to the vehicle (9); a processing unit, configured to process the values of the position parameter in real time to derive information regarding an actual position of the support structure (3) relative to the vehicle (9).

Description

technical field [0001] The invention relates to a device and a method for calibrating sensors of an advanced driver assistance system of a vehicle. Background technique [0002] In the field of driver assistance systems, target units used in procedures for aligning and calibrating advanced driver assistance systems can be mounted on trolley-like structures. [0003] For example, patent document WO2018 / 067354A1 proposes a trolley structure for supporting an optical target for calibrating a vehicle camera and a metal target for calibrating a vehicle radar sensor. [0004] Other trolley structures for calibrating vehicle sensors are described in patent documents US2018 / 0188022A1, WO2017 / 016541 and WO2004 / 102114A1. [0005] These structures must be arranged at a predetermined distance in front of the vehicle and oriented in a predetermined manner relative to the vehicle. In fact, each vehicle manufacturer specifies the optimal position of the target unit; therefore, for each v...
