Device for processing pillar A blind zones and automatically identifying road conditions

Abstract

The invention discloses a device for processing pillar A blind zones and automatically identifying road conditions. The device can display the road conditions of the pillar A blind zones stereoscopically with a controlled visual angle, and provide the road conditions and a safe driving path for a driver according to road identification and traffic sign identifying information, and comprises blind zone cameras, a pavement camera, a traffic sign camera and displays, wherein each blind zone camera is provided with a visual angle controller; both the visual angle controllers and the blind zone cameras are mounted on the outer sides of a left pillar A and a ring pillar A; the circular arc-shaped displays are mounted on the inner sides of the pillars A; and the blind zone cameras are connected to the displays through video processors. The device further comprises the processors and a ranging sensor, wherein the processors are connected with the visual angle controllers and the ranging sensor, and connected to a communication bus on a vehicle.

Description

technical field [0001] The invention relates to an automobile auxiliary technology, in particular to an A-pillar blind area processing and road condition automatic identification device for automobiles. Background technique [0002] The A-pillar is the pillar between the front windshield and the front door of the car. From the perspective of driver comfort, the smaller the overlapping angle, the better. The pillars, the installation of the front windshield, and the ability to resist sudden impacts should be as thick as possible. It is difficult to achieve a balance in the design of maintaining the rigidity of the A-pillar while reducing the degree of occlusion of the driver's line of sight, so blind spots are inevitable. Due to the existence of the A-pillar blind zone, the driver needs to look left and right to avoid accidents when driving the vehicle into curves, intersections and merging lines, and to observe the road occupancy conditions of pedestrians and vehicles, whic...

Problems solved by technology

[0003] The problem of A-pillar affecting driving safety has always been a problem of widespread concern in the world. Many enterprises and institutions have spent a lot of energy to solve this problem, but none of them can achieve satisfactory results.

For example, opening holes on the A-pillar and installing plexiglass to overcome the impact of the blind zone. The obvious disadvantage is that it affects the stiffness of the A-pillar and affects safety. There is also the use of image recognition to detect obstacles in the blind zone. The disadvantages are that the software implementation is complicated, the calculation process and The control process is complicated and the time delay is large; another example is a patented technology that uses a camera plus a monitor to directly display images outside the A-pillar. Obstacle position judgment is difficult to locate, inconvenient to use, etc.
