Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Please refer to figure 1 , which shows a schematic flowchart of a preferred simulation test method for lane departure warning limit recognition ability in the present invention.

[0027] A method for simulating and testing lane departure warning limit recognition ability, comprising the following steps:

[0028] (1) According to the preset running speed, control the marquee with the light source matrix to run to simulate the speed of the car;

[0029] During specific implementation, multiple light source matrix strips are arranged in parallel to simulate lane dividing lines. According to the actual situation, adjust the running speed of the marquee with the light source matrix to simulate the speed of the car.

[0030] (2) According to the preset brightness and gray scale, adjust the brightness and gray scale of the light source matrix strip...

Abstract

The invention discloses a simulation test method for the limit identification capability of lane departure early-warning. The method comprises: (1), according to a preset running speed, a horse race lamp of a light source matrix band is controlled to work; (2), according to preset brightness and gray values, the brightness and gray values of the light source matrix band are adjusted; (3), on the basis of a preset departure speed, a lane departure early-warning device is controlled to make departure movement relative to the light source matrix band and whether the lane departure early-warning device carries out alarming is observed; and (4), if so, the brightness and gray values of the light source matrix band express the limit identification capability of the lane departure early-warning device at the departure speed; and if not, the brightness or gray value of the light source matrix band is adjusted and the step (3) is carried out again. In addition, the invention also discloses a simulation test system for the limit identification capability of lane departure early-warning. With the method, the limit identification capability of the lane departure early-warning device can be tested in a laboratory, so that inconvenience of weather restriction can be eliminated.

Description

technical field [0001] The invention relates to a simulation test method and a test system for lane deviation early warning limit recognition ability. Background technique [0002] Now when testing the limit recognition ability of the lane departure warning device, it is usually only in heavy fog, severe foggy weather or heavy rainy weather. In this case, subject to the limitation of the weather, if there are no weather conditions, it cannot be changed; nor can the limit recognition ability be tested. It can only be tested when the next weather condition permits. This testing method is very invariant and inefficient. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the present invention provides a simulation test method for the limit recognition ability of the lane departure warning, which tests the limit recognition ability of the lane departure warning device in the laboratory, so as to overcome the limitations of ...
