Embodiment 1

[0053] figure 2 It is a flow chart of an embodiment of a method for checking the visual field regulations of exterior rearview mirrors of automobiles provided by the present application.

[0054] like figure 2 As shown, the field of vision regulation check method provided in this embodiment is used to check whether the lens designed in the design stage to be used as the exterior rearview mirror of a car meets the requirements of the regulations. The specific check method includes the following steps:

[0055] S101: Obtain vehicle hard point parameters of the vehicle.

[0056] The above-mentioned vehicle hard point parameters include the R point and the lens data of the exterior rearview mirror. The R point is specified in GB11562, which refers to the design point specified by the vehicle manufacturer for each seating position, and is determined by the (x, y, z) three-dimensional coordinate system. Lens data includes the radius of curvature r of the exterior rearview mirro...

Embodiment 2

[0096] image 3 It is a structural block diagram of an embodiment of a method for checking the visual field regulations of the exterior rearview mirror of an automobile provided by the present application.

[0097] like image 3 As shown, the field of view regulation check system provided by this embodiment is used to check whether the lens designed in the design stage as the exterior rearview mirror of a car meets the requirements of the regulations. The specific check system includes a parameter acquisition module 10 , a first model building module 20 , a visual area drawing module 30 , a second model building module 40 , a lens area forming module 50 and a compliance determination module 60 .

[0098] The parameter acquiring module 10 is used for acquiring the vehicle hard point parameters of the automobile.

[0099] The above-mentioned vehicle hard point parameters include the R point and the lens data of the exterior rearview mirror. The R point is specified in GB11562...

Abstract

The application discloses a method and a system for checking an outside rear-view mirror of an automobile according to vision regulations. The method concretely comprises the steps of acquiring hard point parameters of a full vehicle of the automobile; building a full vehicle model of the automobile according to the hard point parameters of the full vehicle; drawing a plurality of regulated visual areas according to the hard point parameters of the full vehicle, the full vehicle model and the requirements of the regulations; building a model of the outside rear-view mirror according to the hard point parameters of the full vehicle; acquiring a plurality of reflection points, formed on a lens model of the model of the outside rear-view mirror, of the regulated visual areas according to the model of the outside rear-view mirror, wherein a closed area formed by the plurality of reflection points is a lens area needed by the regulated visual areas on the lens model; if a designed actual lens can completely contain the lens area, determining that the actual lens meets the requirements of the regulations; otherwise, determining that the actual lens does not meet the requirements of the regulations. Under the condition that the actual lens does not meet the requirements of the regulations, the actual lens can be designed again until meeting the requirements of the regulations, so that the problem that the designed outside rear-view mirror cannot meet the requirements of the regulations is avoided.

Description

technical field [0001] The present application relates to the technical field of automobiles, and more specifically, relates to a method and system for checking visual field regulations of exterior rearview mirrors of automobiles. Background technique [0002] The exterior rearview mirror is a necessary tool for the driver to observe the rear road conditions or incoming vehicles while driving a car. It is necessary for safe driving and can provide the driver with the field of view of the exterior rearview mirror. The field of view of the exterior rearview mirror refers to the The indirect view of the rear of the car and the surrounding environment obtained by the mirror can play a role in providing driving assistance for the driver. Among them, the national standard GB15084 has made clear regulations on the field of view of the exterior rearview mirror of the car, such as figure 1 As shown, that is to say, the car's rearview mirror must provide the driver with a standard ex...
