Embodiment 1

[0030] Embodiment 1: road test is a very important content of driverless car performance test. For unmanned vehicles, sometimes it is necessary to test their performance on different moving target 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 immature. Most of the moving trajectories of the existing test devices are fixed, the route planning is not systematic, and the accuracy of the moving target's trajectory is not high and does not have randomness. The availability of vehicle performance data is relatively small, which is not a good way to test the actual operating performance of self-driving cars.

[0031] The invention records a movi...

Embodiment 1

[0036] 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 moving speeds of the moving objects are different. Embodiment 2: Assume that the traveling speeds of the moving objects are the same, but the traveling paths are different. Embodiment 3: Assume that the moving target and the unmanned vehicle are traveling in the same direction.

Embodiment approach 1

[0037] Embodiment 1: Assume that the driving trajectories are the same, but the moving speeds of the moving targets are different, such as Figure 4 shown. The moving target 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. Fix the human device on the roller trolley, start the test, make the human device run to the left side of the road, control the speed of the motor on the rope to control the moving speed of the human device, the sensor detects that the car starts to run, and controls the moving target at 0.5m / s speed across the road to detect the detection function of the driverless car obstacle avoidance system. Use the same method to detect other speed devices. Even if the unmanned vehicle cannot accurately detec...

Abstract

The method of testing unmanned vehicles with moving targets on the road belongs to the field of unmanned vehicle road test experiments. In order to solve the problem of simulating the running track of moving targets while driving unmanned vehicles, the problem of presenting a variety of road test scenarios with different driving trajectories , fix the cap of the moving target on the deck of the roller trolley, start the device, the motor starts to run, the motor on the left side of the road tightens the rope, the motor on the right loosens the rope, and controls the contraction of the rope, thereby controlling the roller trolley carrying the moving target And make it run on the road test road, the effect is to provide as many test scenarios as possible for driverless cars.

Description

technical field [0001] The invention belongs to the field of unmanned vehicle road test experiments, and in particular relates 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 o...
