Automobile A pillar perspective vehicle-mounted display device

Abstract

The invention discloses an automobile A pillar perspective vehicle-mounted display device which reflects dynamic changes of driver sight angles. Cameras are arranged both inside an automobile and outside the automobile, the cameras outside the automobile are used for collecting surrounding sight information of a road ahead, and the cameras inside the automobile are used for obtaining driver vision information; according to driver sight concerning angles, images concerned by a driver are cut from images obtained by the cameras outside the automobile; flexible liquid crystal display screens are arranged on the inner side of an A pillar in an attaching mode according to the radian of the A pillar to display images; the images displayed on the flexible liquid crystal display screens inside the automobile are changed in real time according to driver sight angle change information collected by the cameras inside the automobile; the angle and the size of a driving scene image, collected by the cameras outside the automobile, at the position of a blind region are changed in real time, and an A pillar display system can be adjusted in a self-adaption mode according to sight needing regions detected through sight tracking. Therefore, external road traffic environment information which is more complete, more accurate and good in driver acceptability is provided for the driver, and the safety and the convenience of automobile driving are improved.

Description

technical field [0001] The invention relates to an automobile safety device, in particular to an on-vehicle image display system which reflects the dynamic change of the driver's sight angle and makes the A-pillar transparent. Adaptively adjust the angle and size of the screen in real time according to the needs of the driver's attention area, so that it is more convenient and quick to obtain driving surround view information. Background technique [0002] The pillar between the windshield and the front door of the car is called the A-pillar. Because the A-pillar will block the driver's part of the line of sight during driving, it will cause a visual blind spot, such as figure 1 shown. The existence of the A-pillar blind spot is one of the important causes of traffic accidents. The inconvenience of sight blocking is more obvious especially when the driver is turning or changing lanes. Therefore, we hope that the narrower the A-pillar, the better, and the A-pillar supports t...

Problems solved by technology

[0003] Most of the existing A-pillar visual barrier elimination devices install the display on the inner side of the A-pillar and mostly use a liquid crystal display, which cannot completely fit the A-pillar, and cannot intelligently adjust the observation screen, or manually press the display button to adjust the outside of the vehicle. Scene images, not only distracting and time-consuming during debugging, but also pose safety hazards in emergency situations

Someone proposes to use the distance sensor to detect the distance between the driver's body and the screen to adjust the display screen. Although it solves the potential safety hazard without manual operation, the prediction effect is not good, the accuracy drops, and it is impossible to correctly estimate the direction the driver is really looking at.
