Embodiment 1

[0011] Example 1: Road test is a very important content in the performance test of driverless car. For unmanned vehicles, it is sometimes necessary to test their performance through different obstacles and the ability to deal with emergencies. As an emerging technology, driverless vehicle road testing uses sensing systems to sense the road environment and obstacle information to control the steering and speed of the vehicle, so that the vehicle can drive on the road safely and reliably. 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 spot test link and are directly exposed to the test environment. When the moving target suddenly appears in front of the driving vehicle, the car cannot adjust the driving route in time, so it cannot avoid collision with the test equipment, and the driving trajectory of the moving target is not high and random, and the...

Embodiment approach 1

[0029] To further illustrate the device of the present invention, the following two assumptions are made. Embodiment 1: It is assumed that the driving trajectory is the same, but the driving speed of the test equipment is different. Embodiment 2: It is assumed that the driving speed of the testing equipment is the same, but the driving path is different. Embodiment 3: Different test equipments, different form paths and test equipments go toward each other.

[0030] Embodiment 1: It is assumed that the traveling trajectories are the same, but the traveling speeds of the moving objects are different. The testing equipment of the device of the present invention is various, and the human equipment is mainly used as an example to describe the specific implementation process in detail. 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 11 is ...

Embodiment approach 2

[0031] Embodiment 2: It is assumed that the driving speed of the testing equipment is the same, but the driving path is different. The device of the present invention provides four driving routes for the test equipment, such as figure 2 shown. Taking a simulated motorcycle as an example to further illustrate the device of the present invention, assuming that the motorcycle runs at a constant speed of 8m / s, it is placed on the route 1, route 2, route 3, and route 4 for testing, because the driving route of the real motorcycle has different characteristics. 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. To prevent unmanned vehicles from detecting moving targets, stick some tin foil inside the test equipment to enhance its ability to transmit signals. When the test starts, the unmanned vehicle 11 is started, and when the sensor senses the vehicle, the moving target ...

Abstract

An unmanned vehicle test device with a controllable road surface moving target, which belongs to the field of unmanned vehicle road test experiments. In order to solve the problem of simulating the running state of obstacles during the driving of unmanned vehicles, it presents a variety of roads with different driving trajectories. The problem of the test scene. The pulley trolley is a self-driving car with an electromagnet installed on it. The pulley trolley is located between the road surface and the lower surface of the glass road slab. It is running on the road. The sliding board has embedded balls and is placed on the upper surface of the glass road slab. Asphalt road, and located above the corresponding electromagnet of the pulley trolley, so that the electromagnet of the pulley trolley under the glass road slab is powered on, and can attract the metal sliding board above the glass road slab, so that the metal sliding board can pass through Electromagnets move the trolley along with it, and the effect is to provide as many test scenarios as possible for the self-driving car.

Description

technical field [0001] The invention belongs to the field of road test experiments of unmanned vehicles, in particular to an obstacle avoidance system used for detecting unmanned vehicles, which are close to real controllable road moving targets. Background technique [0002] In recent years, the development of driverless cars and their corresponding detection technologies have become a hot issue. The driverless car senses the road environment through the on-board sensing system, automatically plans the driving route and controls the vehicle to reach the predetermined target, and at the same time senses the surrounding environment through the on-board sensor, and controls the vehicle's driving according to the road, vehicle position and obstacle information obtained from the perception. Steering and speed so that the vehicle can be driven on the road safely and reliably. With the continuous integration of various technologies in unmanned vehicle technology, and the increasi...
