Embodiment 1

[0033] See Figure 1 In this embodiment, a backlight test field for self-driving vehicles is provided, which includes a road 2, a tunnel 3, a backlight emitting device 6 and a controller 7.

[0034] The tunnel 3 is erected on the road 2, and the two ends of the tunnel 3 are set as tunnel entrance 4 and tunnel exit 5, respectively. The backlight emitting device 6 is fixed in the tunnel 3 and can emit backlight toward the tunnel entrance 4. The controller 7 is electrically connected with the backlight emitting device 6 to control the backlight emitting device 6 to be turned on and off, wherein when the backlight emitting device 6 is turned on, a backlight scene is formed in the tunnel 3.

[0035] The process of testing with the test field is:

[0036] The vehicle to be tested 1 is placed on the road 2 at a distance from the tunnel entrance 4, and before the vehicle to be tested 1 starts the backlight test, the controller 7 controls the backlight emitting device 6 to be turned on. At ...

Embodiment 2

[0049] refer to Figure 2 On the basis of the test field and test method described in Embodiment 1, the test field and scene layout also include an operation test management center 8 capable of sending and receiving information, and the operation test management center 8 is provided with a backlight test module.

[0050] The operation management center 8 is connected with the controller 7. When the backlight test module of the operation test management center 8 is started, the operation test management center 8 sends a start instruction to the controller 7, and the controller 7 controls the backlight emitting device 6 to start after receiving the start instruction. The start-up of the backlight test module can be the operation of the tester to the operation test management center 8, such as the password given to the operation test management center 8, or the backlight test module is connected with a switch button, and the switch button is pressed to start the backlight test module....

Embodiment 3

[0054] refer to Figure 2 Further, on the basis of the test field and test method of Embodiment 2, the test field and scene arrangement further includes:

[0055] Operation management center 8 includes the following different backlight test modules: sunlight backlight test module, passing low beam test module and passing high beam test module.

[0056] The backlight emitting device 6 includes a variable brightness projection lamp and an automobile headlamp, and the automobile headlamp has a low beam adjusting function and a high beam adjusting function.

[0057] When the sunlight backlighting test module is started, the operation test management center 8 sends the variable brightness floodlight starting instruction to the controller 7, and the controller 7 controls the variable brightness floodlight to start after receiving the variable brightness floodlight starting instruction. Among them, the brightness when the variable brightness floodlight is turned on can be the brightness v...

Abstract

The invention relates to an automatic driving vehicle backlight test field and a test method. The test method includes scene layout on the test field and response of the vehicle to be tested. The scene layout is as follows: the test field includes roads, tunnels, controllers and backlight emitting devices. The tunnel is erected above the road, and the two ends of the tunnel are set to be the tunnel entrance and the tunnel exit respectively. The backlight emitting device is fixed in the tunnel and emits backlight toward the tunnel entrance. The controller controls the backlight emitting device to be turned on and off. When the backlight emitting device is turned on, a backlight is formed. Scenes. The response of the vehicle to be tested is: the vehicle to be tested normally enters the tunnel with the backlight scene, and finally completes the safe driving in the tunnel with the backlight scene, ensuring that the vehicle’s trajectory, speed and lane keeping are all set within the safe range. Using the backlight test field of the present invention to carry out the backlight test does not require the target vehicle to consume the resources of the test field, and the backlight test can be performed at any time, and the test cost is low.

Description

Technical field [0001] The invention relate to that technical field of automobile intelligent test field, in particular to a backlight test field and a test method for self-driving vehicles. technical background [0002] For a manned vehicle, when driving in the backlight, the driver's sight is affected by strong light, and the road ahead can't be observed clearly or the color of traffic lights can't be distinguished. Instantaneous strong light irradiation may also cause the driver to be blind in a short time, and serious situations such as rear-end collision, careless driving into the opposite lane, etc. may endanger the life safety of himself or others. [0003] Therefore, for self-driving vehicles, the backlight test is to detect the lane identification and lane keeping functions of the vehicle, and it is one of the important bases for the safety strategy formulation of intelligent driving vehicles. Backlight mainly includes sunlight and the lights of cars coming from the oppo...
