Detailed Description
Example 1: road test is an important content for testing the performance of the unmanned automobile. It is also sometimes desirable for an unmanned vehicle to test its ability to pass through different moving target surfaces, and to respond to sudden conditions. As a new technology, driverless vehicle drive test senses road environment and obstacle information through a sensing system to control the steering and speed of a vehicle, so that the vehicle can safely and reliably travel on the road. Technical conditions such as an experimental method and tools in the field are not mature at present, the moving track of a moving target of an existing testing device is mostly fixed, route planning is not systematized, the accuracy of the moving track of the moving target is not high and has no randomness, available vehicle performance data are relatively few, and the actual operation performance of an unmanned automobile cannot be well tested.
The invention discloses moving object equipment close to a real driving environment, which is used for detecting an obstacle avoidance system of an unmanned automobile. Through the mechanical structure design with simplicity, practicability and strong operability, the problems of inaccurate moving target running path and no randomness existing in the performance test of the unmanned automobile at the present stage are solved. The device of the invention provides different driving paths of various moving targets for the unmanned automobile, and can greatly improve the testing efficiency of the unmanned automobile.
A testing device close to reality is composed of an unmanned automobile 1, a sensor 2, a motor 3, a motor track 4, a trolley 5 for bearing the motor, a thin rope 6, a roller trolley 7, a moving target 8, a groove 9 for arranging the rope and a groove 10 for arranging the roller trolley.
The unmanned vehicle 1 is a real vehicle, an obstacle avoidance system for detecting the vehicle, and is placed in a test field. The sensor 2 is mainly responsible for detecting the starting of the unmanned automobile and collecting relevant information of the automobile, is arranged at an entrance of a test road section, and plays a role in enabling the automobile and test equipment to run simultaneously. The motor 3 is mainly responsible for the longitudinal operation of the moving object. The motor is connected to an external power source, acts on the trolley and places it on the track 4. The motor track 4 mainly provides a running track for the motor, so that the motor can run conveniently. This can be assumed in the present invention as the Y-axis. The trolley 5 for carrying the motor is made of steel materials and mainly used for enabling the motor to longitudinally displace. The thin rope 6 is a steel wire rope with the diameter of 5mm, two ends of the rope are respectively connected to the motors on the two sides, and the middle of the rope is connected with the roller trolley. Mainly takes charge of the movement of the moving target in the transverse direction. The steel wire rope has certain weight, high strength, stable work, difficult abrupt whole breakage, reliable work and more regular shape. The roller trolley 7 is made of steel materials, two ends of the roller trolley are partially extended to play a role in connecting the road surface, and 8 small clamping seats which are unevenly distributed and used for connecting a moving target are arranged above the roller trolley, as shown in fig. 7. The rollers of the trolley are distributed in a 3 multiplied by 4 structure, as shown in figure 8, the rollers are round balls, so that friction between the rollers and the road surface is reduced, and the rollers can rotate more flexibly. The moving target 8 is a card cap which is used for connecting the roller trolley and is arranged below the moving target based on the point that the moving target is evenly stressed, wherein the moving target comprises a simulated human, a simulated motorcycle, a simulated electric vehicle, a simulated dog and the like, and the lower part of the moving target is fixed on the roller trolley 7. In order to simulate the environment close to a real traffic road, tin foil paper can be arranged on the equipment according to experimental requirements and is pasted on the inner surface of the equipment, so that the identification of the millimeter wave radar can be met when the equipment is unmanned. The human equipment moving target mentioned in the present invention can set its temperature to 36.5 c, simulating human body constant temperature, so that it can be detected even in the night when the vehicle is not driven by a human. The driving path of the moving target can be adjusted at will, and various test scenes can be conveniently simulated. The groove 9 for arranging the rope is provided with a groove adaptive to the thickness of the rope at the end point of the test field, and the rope is mainly arranged. This can be assumed in the present invention as the X-axis. The right side of the groove 10 for placing the trolley at the end point of the test site is provided with a groove with a proper size, and the groove is mainly used for placing the roller trolley 7 after the experiment is finished. After the experiment, need not dismantle the gyro wheel dolly, convenient use next time. The roller trolley is arranged and protected from being damaged.
The device is arranged in a relatively open field, and the road surface device comprises an unmanned automobile, a sensor, a motor track, a trolley for bearing the motor, a string, a roller trolley, a moving target, a groove for arranging the rope, a groove for arranging the trolley and the like, and is shown in figure 1. The clamp cap of the moving target is fixed on the clamp seat of the trolley, the device is started, the motor starts to operate, the motor on the left side of the road tightens the motor on the right side of the rope to loosen the rope, the motor controls the contraction of the rope in such a way, and therefore the trolley bearing the moving target is controlled to operate on a road surface to be tested. The sensor detects that the driverless vehicle has begun operation, at which time the starter motor also begins operation. If the moving target is displaced longitudinally, the motors at two ends of the road can be controlled to run forwards simultaneously. If the moving target is transversely displaced, the motors at two ends of the road can control the contraction of the ropes. The running track of the motor is regarded as an axis Y, and the transverse running track of the roller trolley is regarded as an axis X. Thus, the moving route of the moving object can be changed at will. And the experimental device can be accurately and effectively tested. The test is ended, and control bears the motor dolly and is the motor, and control road left side motor when moving the road top and relax, the right side motor tightens up, makes the gyro wheel dolly put just in the recess 10 of settling the gyro wheel dolly, because this recess is less than the experiment place, places the in-process of this recess when the gyro wheel dolly, because of the rope is in lax state, so the rope also will fall into the recess 9 of settling the rope just, and the experiment is ended.
The test is assumed to be performed with a bicycle as a moving object, as shown in fig. 2, assuming that the bicycle intends to traverse the road. The front wheel and the rear wheel of the simulation bicycle are respectively provided with a clamping cap which is connected to the clamping seat of the roller trolley. The device is started, and the motor is controlled to enable the roller trolley to bear the left end of the simulated bicycle running to the road. The sensor detects that the unmanned automobile starts to run at a certain speed, and the motor is controlled to control the contraction of the rope, so that the moving target generates transverse displacement, namely the running of the unmanned automobile is simulated to the right front. If the automobile does not detect the simulated bicycle so as to cause collision, the simulated bicycle is made of rubber materials, so that the unmanned vehicle cannot be damaged. For the bicycle, even if the bicycle is crashed to fly, the bicycle can be quickly recovered after the bicycle is deformed due to the elasticity of the rubber. Because the bicycle passes through roads in real life in various conditions, the invention also assumes that the running route of the bicycle is changed suddenly when the bicycle runs linearly, and controls the motor to move on the track and control the motor to contract the rope at the same time, thereby controlling the changed track of the bicycle, and the track and the direction can be set at will. After the test is finished, the roller trolley is put back into the groove, and the roller trolley is convenient to use next time. The test environment is diversified, and systematic detection can be carried out on the obstacle avoidance function of the unmanned automobile.

In a real road environment, the running environment of a vehicle is various. Based on this, a drive test environment is assumed in which a moving object travels toward the unmanned vehicle. And starting the roller trolley to move to the middle position of the road top end when the test is started, detecting that the automobile starts to move by the sensor, and controlling the moving target to move along the Y axis at a certain speed. The number of the moving targets can be increased according to the requirement of a test environment, and the hypothesis can be used for testing whether the unmanned automobile can sense that a plurality of obstacles exist in front or not when a plurality of moving targets exist in the front; whether the running speed of the moving target can be judged so as to decide which obstacle is avoided first; whether the moving target is closest to the unmanned automobile can be judged, so that the driving speed of the unmanned automobile is determined, and the obstacle can be safely avoided.
