Abstract

An inspection device for vehicle driver assistance systems (DASs) mounted on a vehicle may include: i) a frame unit including pillar frames, where vehicles forwardly enter and backwardly exit, at respective corners of a base frame, and an upper frame is coupled to upper end portions of the pillar frames; a correction unit installed at the upper frame such that it is movable in multi-axis directions so as to correct a camera measurement point of a lane departure warning system (LDWS) at a front side of the vehicle and configured to display a correction target with respect to the camera as an image; and an inspection unit installed at the upper frame such that it is movable in multi-axis directions so as to check a normal operation of the LDWS and configured to display a driving lane as an image.

Claims

1. An inspection device of vehicle driver assistance systems (DASs) mounted on a vehicle, comprising:

a frame unit including pillar frames, where vehicles forwardly enter and backwardly exit, at respective corners of a base frame, wherein an upper frame is coupled to upper end portions of the pillar frames;

a lane departure warning system (LDWS) correction unit installed at the upper frame such that it is movable in multi-axis directions so as to correct a camera measurement point of a lane departure warning system (LDWS) at a front side of the vehicle and configured to display a correction target with respect to the camera as an image;

a lane departure warning system (LDWS) inspection unit installed at the upper frame such that it is movable in multi-axis directions so as to check a normal operation of the LDWS and configured to display a driving lane as an image; and

an SCC inspection unit configured to check a normal operation of a smart cruise control (SCC) system at the front side of the vehicle,

wherein the SCC inspection unit is installed at the base frame such that it is movable in multi-axis directions, and includes a first target member including at least one first radar reflector with respect to the SCC,

wherein the first radar reflectors are provided in plural at the first target member, and

wherein the SCC inspection unit further includes a blocking member that is configured to unblock any one of the first radar reflectors and block the remaining ones or to block any one of the first radar reflectors.

2. The device of claim 1, further comprising

a position aligning unit installed at the base frame and configured to align different kinds of vehicles at a predetermined position.

3. The device of claim 1, further comprising

inspection units respectively installed at the frame unit and configured to check normal operations of DASs including a smart cruise control (SCC) system, blind spot detection (BSD) system, and around view monitoring (AVM) system.

4. The device of claim 1, further comprising

a BSD inspection unit installed at the upper frame at a vehicle entry side so as to check a normal operation of a blind spot detection (BSD) system at rear sides of the vehicle.

5. The device of claim 4, wherein

the BSD inspection units are installed as a pair at the upper frame, such that they are movable in multi-axis directions and respectively include a second target member including a second radar reflector with respect to the BSD.

6. The device of claim 5, wherein

the second target member is installed at the upper frame such that it is movable in forward, backward, width, and length directions of the vehicle by a fourth moving unit.

7. The device of claim 6, wherein

the second target member is provided such that it is upwardly and downwardly swingable by the actuating cylinder when vehicles enter or exit.

8. The device of claim 4, further comprising

an around view monitoring (AVM) inspection unit installed at a top surface of the base frame so as to check normal operations of respective AVMs at front and rear sides of the vehicle and both lateral sides of the vehicle.

9. The device of claim 8, wherein

the AVM inspection unit includes a plurality of third target members, which are installed on a top surface of the base frame such that they are movable in the forward and backward directions.

10. The device of claim 9, wherein

the third target members are installed at the base frame such that they are movable in forward and backward directions by an actuating cylinder and a link member.

11. The device of claim 1, wherein

the LDWS correction unit includes at least one first LCD monitor that displays a correction target and is configured to adjust an image position and an image size of the correction target.

12. The device of claim 11, wherein

the first LCD monitor is installed such that it is movable in forward, backward, width, and length directions of the vehicle by a first moving unit including a servo motor and an actuating cylinder.

13. The device of claim 1, wherein

the LDWS inspection unit includes a second LCD monitor that displays a driving lane and is configured to adjust an image position and an image size of the driving lane.

14. The device of claim 13, wherein

the second LCD monitor is installed at the upper frame such that it is movable in forward, backward, width, and length directions of the vehicle by a second moving unit including a servo motor and an actuating cylinder.

15. The device of claim 1, wherein

the first target member is installed at the base frame such that it is movable in forward, backward, width, and length directions of the vehicle by a third moving unit including a servo motor.

16. The device of claim 1, wherein

the blocking member is installed at the first target member such that it is reciprocally movable in width directions of the vehicle by an actuating cylinder.

17. An inspection device for inspecting various kinds of vehicle driver assistance systems (DASs) mounted on a vehicle, comprising:

a frame unit including pillar frames, where the vehicle is moved forward to enter and is moved backward to exit, at respective corners of a base frame, wherein an upper frame is coupled to upper end portions of the pillar frames;

a position aligning unit installed at the base frame and configured to align different kinds of vehicles at a predetermined position;

a lane departure warning system (LDWS) correction unit installed at the upper frame such that it is movable in accordance with a front side of a vehicle in forward, backward, width, and length directions of the vehicle so as to correct a camera measurement point of an LDWS at the front side of the vehicle and configured to display a correction target with respect to the camera as an image;

an LDWS inspection unit installed at the upper frame such that it is movable in accordance with the front side of the vehicle in the forward, backward and length directions and configured to display a driving lane as an image so as to check a normal operation of the LDWS;

a smart cruise control (SCC) inspection unit installed at the base frame such that it is movable in accordance with the front side of the vehicle in forward, backward, width, and length directions of the vehicle so as to check a normal operation of an SCC at the front side of the vehicle;

a blind spot detection (BSD) inspection unit at the upper frame, which connects a pair of pillar frames at a vehicle entry side, such that it is movable in the forward, backward, the width, and the length directions of the vehicle so as to check normal operations of BSDs at the rear side of the vehicle; and

an around view monitoring (AVM) inspection unit installed at a top surface of the base frame such that it is movable in the forward and backward directions so as to check normal operations of AVMs at the front and rear sides of the vehicle and both lateral sides of the vehicle

wherein the SCC inspection unit includes a first target member including at least one first radar reflector with respect to the SCC,

wherein the first radar reflectors are provided in plural at the first target member, and

wherein the SCC inspection unit further includes a blocking member that is configured to unblock any one of the first radar reflectors and block the remaining ones or to block the any one of the first radar reflectors.
