Problems solved by technology

[0004] 1. Renovate the structure of the A-pillar of the car, and design the A-pillar into a Y-shaped hollow design, so that the area where the driver is blocked by the A-pillar is reduced. Although this method solves the problem of the blind area of ​​the A-pillar of the car to a certain extent, it changes the The appearance and structure of the A-pillar reduce the bearing capacity and firmness of the A-pillar, and reduce the safety performance of the A-pillar. When the car is hit, there are serious safety hazards, and the effect is limited, and the blind spot cannot be completely eliminated;
[0005] 2. Install a camera on the outside of the vehicle, embed an electronic display on the A-pillar, and present the angle of view of the blind spot on the internal display of the car through the camera. This method of electronic display will stimulate the driver's eyes, which will cause light pollution in the cab and affect Improve the driver's sight and safe driving;
[0006] 3. Set up small triangular windows on the left and right front windshields of the vehicle to expand the field of vision. This method has no obvious effect in the actual driving process and has not completely solved the problem of A-pillar blind spots
[0007] Therefore, the existing technologies for eliminating the A-pillar blind area of ​​automobiles all have negative effects such as changing the structure of the A-pillar or producing light pollution, and the effect of eliminating the A-pillar blind area is not good, which affects the safety performance and safe driving of the car.

Embodiment 1

[0067] Embodiment one, as figure 1 Shown, a kind of elimination device that is used to eliminate the blind spot of automobile A pillar, comprises blind spot image collector 1, driver's face image collector 2, controller 3, display 4 and negative refractive index lens 5;

[0068] The blind spot image collector 1 is arranged on the outside of the car, and is used to collect the blind spot image of the A pillar of the car;

[0069] Described driver's face image collector 2 is arranged on the inside of the car, for collecting the driver's face image;

[0070] The controller 3 is arranged inside the car and is used to obtain the turning signal of the car, judge whether the car is turning according to the turning signal of the car, if so, send the image of the blind spot to the display 4, and if not, identify the Facial image, get the recognition result, and judge whether the driver is looking at the A-pillar of the car according to the recognition result, if so, send the blind sp...

Embodiment 2

[0115] Embodiment two, such as Figure 4 As shown, a method for eliminating the blind area of ​​the A-pillar of an automobile is applied in a device for eliminating the blind area of ​​the A-pillar of an automobile in Embodiment 1, comprising the following steps:

[0116] S1: Collect the blind spot image of the A-pillar of the car, and obtain the turn signal of the car;

[0117] S2: Judging whether the car is turning according to the turning signal of the car, if so, display the image of the blind spot and execute S3; if not, collect the facial image of the driver, and recognize the facial image to obtain the recognition result, according to the described The recognition result judges whether the driver is looking at the A-pillar of the car, if so, then display the blind spot image and execute S3, if not, then do not display the blind spot image;

[0118] S3: performing light refocusing on the blind spot image, and forming an air image in the air within the driver's field of ...

Embodiment 3

[0126] Embodiment three, as figure 1 Shown, a kind of automobile comprises the elimination device for eliminating the blind spot of automobile A pillar among the embodiment one, also comprises vehicle body 10, automobile A pillar 20, front windshield 30, left rearview mirror 40 and right rearview mirror 50.

[0127] Preferably, as figure 1 As shown, it includes two eliminating devices for eliminating the blind area of ​​the A-pillar of the automobile, and the two eliminating devices for eliminating the blind area of ​​the A-pillar of the automobile are arranged symmetrically.

[0128] Since the car includes two A-pillars, it is more convenient for the two eliminating devices to eliminate the blind spots of the corresponding A-pillars without interfering with each other through the symmetrical arrangement of two eliminating devices for eliminating the blind spots of the A-pillars of the car, thereby completely solving the problem of A-pillar blind spots. The problem of the ...

Abstract

The invention relates to an automobile, and an eliminating device and method for eliminating an A-pillar blind area of the automobile. The device comprises a blind area image collector, a driver faceimage collector, a controller, a display and a negative refractive index lens. The controller acquires an automobile steering signal, whether the automobile steers or not is judged according to the automobile steering signal, if yes, a blind area image collected by the blind area image collector is sent to the displayer, and if not, a face image collected by the driver face image collector is recognized, a recognition result is obtained, whether the driver looks at the automobile A pillar or not is judged according to the recognition result, and if yes, the blind area image is sent to the displayer, and the negative refractive index lens is used for carrying out light refocusing on the blind area image displayed by the display and forming an air image in the air within the visual field range of the driver. On the premise that the appearance and the structure of the automobile A pillar are not changed, the blind area problem of the automobile A pillar is effectively solved, light pollution is avoided, the automobile driving safety coefficient can be effectively increased, and the traffic accident rate is reduced.

Description

technical field [0001] The invention relates to the technical field of safe driving of automobiles, in particular to an automobile and an eliminating device and method for eliminating the blind area of ​​an A-pillar of the automobile. Background technique [0002] Generally, there are three columns on each side of the car body. Among them, the connecting columns connecting the roof and the engine compartment in the left and right fronts of the car are called A-pillars. The A-pillars of automobiles are an indispensable part of the current mainstream frame structure. However, the existence of the A-pillar will inevitably form a visual blind spot, which will block the driver's line of sight and bring potential safety hazards. According to statistics, 20% of traffic accidents are caused by car blind spots. Therefore, eliminating the blind spot of the A-pillar of the automobile is very important in the field of safe driving of the automobile. [0003] Existing methods for solvi...
