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...
