Embodiment 1

[0011] Embodiment 1: road test is a very important content in the driverless car performance test. For unmanned vehicles, sometimes it is necessary to test its performance through different obstacle roads and the ability to deal with emergencies. As an emerging technology, unmanned vehicle road test controls the steering and speed of the vehicle by sensing the road environment and obstacle information through the sensor system, so that the vehicle can drive safely and reliably on the road. At present, the technical conditions such as experimental methods and tools in this field are not mature, and most of the existing obstacle assistance devices do not have a blind zone test link, and are directly exposed to the test environment. When a moving target suddenly appears in front of the driving vehicle, the car cannot adjust its driving route in time, so it cannot avoid collision with the test equipment, and the accuracy of the moving target's driving trajectory is not high and ra...

Embodiment approach 1

[0029] To further illustrate the device of the present invention, the following two assumptions are made. Embodiment 1: Assume that the driving trajectories are the same, but the driving speeds of the test equipment are different. Embodiment 2: Assume that the traveling speed of the surveying and designing equipment is the same, but the traveling paths are different. Embodiment 3: different test equipments, different forms of paths and the test equipments run towards each other.

[0030] Embodiment 1: Assume that the driving trajectories are the same, but the moving speeds of the moving objects are different. The test equipment of the device of the present invention is various, and the specific implementation process is described in detail by mainly taking human equipment as an example. The human equipment runs at speeds of 0.5m / s, 0.8m / s, 1m / s, and 1.2m / s respectively, and is placed on the same driving route for testing each time. When the test starts, the unmanned vehicle...

Embodiment approach 2

[0031] Embodiment 2: Assume that the traveling speed of the surveying and designing equipment is the same, but the traveling paths are different. The device of the present invention offers four driving routes for the test equipment, such as figure 2 shown. Further illustrate the device of the present invention with the example of simulated motorcycle, assuming that the motorcycle runs at a constant speed of 8m / s, it is placed on route 1, route 2, route 3, and test on route 4, because the driving route of the real motorcycle has different Stability, the four routes set up in the present invention are all representative routes. Because the motorcycle runs faster, the test time should be shorter. In order to prevent unmanned vehicles from detecting moving targets, some tinfoil can be pasted inside the test equipment to enhance its ability to transmit signals. The test starts, the unmanned vehicle 11 is started, and when the sensor senses the vehicle, the moving target on the ...

Abstract

The invention discloses a method for testing a driverless automobile by using a moving target, belongs to the field of driverless automobile road test experiments, and aims to present road test sceneswith various different running tracks during the simulation of the running state of an obstacle in the running process of a driverless automobile. A device is arranged an open site; the moving targetcan be a simulated pedestrian or a motorcycle or an electric vehicle or a dog; the moving target is vertically placed beside a road initially; tin foil paper is pasted to the inner surface of the moving target and used for enabling a millimeter-wave radar to recognize the moving target in an unmanned driving test; a real vehicle is arranged on one side of the moving target, parks on the roadsideand is fixed in situ without moving; a blind area environment with a certain range is provided for the moving target, the blind area is similar to a triangular area; and as many test scenes as possible are provided for the driverless automobile.

Description

technical field [0001] The invention belongs to the field of unmanned vehicle road test experiments, in particular to a controllable road surface moving target close to reality, which is used to detect the obstacle avoidance system of the unmanned vehicle. Background technique [0002] In recent years, the development of unmanned vehicles and their corresponding detection technologies have become hot issues. The driverless car perceives the road environment through the on-board sensor system, automatically plans the driving route and controls the vehicle to reach the predetermined target. Steering and speed so that the vehicle can move safely and reliably on the road. With the continuous integration of various technologies in unmanned vehicle technology, and the increasing intelligence and complexity of unmanned vehicles, more efficient and comprehensive detection devices are required. Road testing is an important means to comprehensively verify the functions of unmanned v...
