Abstract

One form of a driving test system for a moving object includes: an unmanned aircraft configured to fly at a set distance from the moving object that is configured to drive along a set route in a set zone and has a vision sensor disposed on one side that is configured to detect the moving object'"'"'s motion;

and a controller configured to control the flight of the unmanned aircraft to follow the moving object and to transmit to the vision sensor and to receive from the vision censor, detected motion characteristics of the moving object.

Claims

1. A driving test system of a moving object comprising:

an unmanned aircraft configured to fly at a set distance from the moving object which is configured to drive along a set route in a set zone and has a vision sensor disposed on one side that is configured to detect a motion of the moving object; and

a controller configured to control the flight of the unmanned aircraft to follow the moving object and to transmit to the vision sensor and to receive from the vision center, detected motion characteristics of the moving object.

2. The driving test system of claim 1, wherein the unmanned aircraft is configured to control the moving object to implement a driving function including an advanced driver assistance system (ADAS), wherein the advanced driver assistance system comprises autonomous emergency braking (AEB), a lane departure warning system (LDWS), a lane keeping assistance system (LKAS), blind spot detection (BSD), or smart cruise control (SCC), and

wherein the vision sensor is configured to detect lanes that the moving object is traveling in and an obstacle near the moving object during implementation of the driving function.

3. The driving test system of claim 2, wherein the moving object is controlled by the unmanned aircraft and the moving object comprises a detector configured to detect surroundings of the moving object.

4. The driving test system of claim 3, wherein the detector is configured to detect lanes, an obstacle near the moving object, and a distance to the obstacle.

5. The driving test system of claim 1, wherein the moving object is controlled by the unmanned aircraft and has an autonomous driving function for automatically controlling a steering device, an accelerator, and a braking device.

6. The driving test system of claim 1, further comprising:

a conveyor with landing and takeoff spots for the unmanned aircraft set therein, the conveyor configured to move the unmanned aircraft from the landing spot to the takeoff spot;

a landing marker formed on one side of the landing spot;

a proximity sensor disposed on the other side of the landing spot and configured to detect the unmanned aircraft; and

photosensors disposed on one side of the takeoff spot that are configured to detect the unmanned aircraft.

7. The driving test system of claim 1, wherein the controller is configured to determine information, speed, and travel distance of the moving object based on information detected by the vision sensor.
