Embodiment 1

[0034] see figure 1 , In this embodiment, a backlight test field for an automatic driving vehicle is provided, and the test field includes a road 2, a tunnel 3, a backlight emission device 6 and a controller 7.

[0035] The tunnel 3 is erected on the road 2, and the two ends of the tunnel 3 are set as the tunnel entrance 4 and the 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 and the backlight emitting device 6 is electrically connected 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 .

[0036] The process of conducting tests using this test ground is:

[0037] The vehicle 1 to be tested is placed on the road 2 at a distance from the tunnel entrance 4. Before the vehicle 1 to be tested starts the backlight test, the controller 7 controls the backli...

Embodiment 2

[0050] refer to figure 2 On the basis of the test field and the test method described in Embodiment 1, the test field and the scene arrangement 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.

[0051] The operation test management center 8 is connected to the controller 7 . When starting the backlight test module of the operation test management center 8, the operation test management center 8 sends a start instruction to the controller 7, and the controller 7 controls the backlight transmitter 6 to turn on after receiving the start instruction. Wherein, the activation of the backlight test module can be the operation of the tester to the operation test management center 8, such as a 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...

Embodiment 3

[0055] refer to figure 2 , further, on the basis of the test field and the test method of embodiment 2, the test field and scene arrangement also include:

[0056] The operation test management center 8 includes the following different backlight test modules: a sunlight backlight test module, a passing vehicle low beam test module, and a passing vehicle high beam test module.

[0057] The backlight emitting device 6 includes a variable-brightness floodlight and a car headlight, and the car headlight has a low beam adjustment function and a high beam adjustment function.

[0058] When starting the sunlight backlight test module, the operation test management center 8 sends a variable-brightness floodlight starting instruction to the controller 7, and the controller 7 controls the variable-brightness floodlight to turn on after receiving the variable-brightness floodlight starting instruction. Among them, the brightness of the variable brightness flood light when it is turned ...

Abstract

The invention relates to an automatic driving vehicle backlight test field and a test method. The test method comprises the steps of performing scene arrangement on the test field and responding to ato-be-tested vehicle. The scene arrangement is as follows: the test field comprises a road, a tunnel, a controller and a backlight emitting device. The tunnel is erected above a road; the two ends ofthe tunnel are set as a tunnel entrance and a tunnel exit respectively; the backlight emitting device is fixed in the tunnel and emits backlight towards the tunnel entrance; the controller controls the backlight emitting device to be turned on and turned off; and a backlight scene is formed when the backlight emitting device is turned on. The response of the to-be-tested vehicle is that the to-be-tested vehicle normally drives into the tunnel forming the backlight scene, finally safe driving in the tunnel provided with the backlight scene is completed, and it is ensured that the driving track,the driving speed and the lane of the to-be-tested vehicle are all kept within a set safety range. When the backlight test field is used for backlight test, a target vehicle does not need to consumetest field resources, the backlight test can be performed at any time, and the test cost is low.

Description

technical field [0001] The present invention relates to the technical field of automobile intelligent test field, in particular to a backlight test field and a test method for automatic driving vehicles. Background technique [0002] For a manned vehicle, when driving in the backlight, the driver's line of sight is affected due to the strong light, and the driver cannot see the road ahead or distinguish the color of the traffic lights. Instantaneous strong light exposure may also cause blindness in a short period of time for the driver, and in severe cases, rear-end collisions, accidental driving into the opposite lane, etc. may endanger the life safety of oneself or others. [0003] Therefore, for autonomous vehicles, backlight test is to detect the functions of vehicle lane recognition and lane keeping, and it is one of the important basis for the formulation of safety strategies for intelligent driving vehicles. The backlight mainly includes sunlight and the lights of ca...
