Abstract
The present disclosure relates to a blockage performance evaluation device, and more particularly, to a blockage performance evaluation device in which a jig unit, a spray unit, and a collection unit may move and rotate independently of one another to evaluate the performance of various blockages, thereby minimizing an evaluation time, performing an accurate test, and improving evaluation reliability.
Claims6
A blockage performance evaluation device, which performs a performance assurance test on an environment recognition sensor of an autonomous vehicle, the blockage performance evaluation device comprising:
- a housing unit;
- a base unit installed in the housing unit;
- a jig unit installed on the base unit and configured such that an environment recognition sensor, which is to be subjected to the performance assurance test, is mounted on the jig unit;
- a spray unit installed on the base unit, disposed adjacent to the jig unit, and configured to spray a fluid to the environment recognition sensor mounted on the jig unit;
- a supply unit configured to supply the fluid to the spray unit;
- and
- a collection unit installed in the housing unit and configured to collect evaluation data and record a performance assurance test evaluation process of the environment recognition sensor mounted on the jig unit,
- wherein the blockage performance evaluation device performs blockage performance evaluation on the environment recognition sensor by moving and rotating the jig unit, the spray unit, and the collection unit independently,
- wherein the jig unit comprises:
- a support part installed on an upper portion of the base unit;
- a turning part turnably coupled to the support part and configured to turn about a turning axis, which is disposed in a longitudinal direction, at a predetermined angle in a width direction;
- and
- a column part installed on an upper portion of the turning part and configured to rotate in conjunction with the turning operation of the turning part,
- wherein the column part comprises:
- a body part installed on the upper portion of the turning part, extending in a vertical direction, and configured to rotate at a predetermined angle about the vertical direction on the upper portion of the turning part;
- and
- a clamping part disposed on the body part, extending in the vertical direction, and configured to clamp or unclamp the environment recognition sensor, and
- wherein a position of the environment recognition sensor clamped by the clamping part is adjusted by the turning operation of the turning part and the rotational operation of the body part.
