System and method for expanding driver's field of vision

Abstract

The invention discloses a visual field expanding system for a car driver. The visual field expanding system for the car driver comprises a blind area integrating rearview mirror, a flexible display device, a car backing auxiliary imaging device, a wide-angle auxiliary imaging device and a processor, wherein the processor is connected with the car backing auxiliary imaging device and a rearview auxiliary imaging device, is used for controlling the rotation angles of the car backing auxiliary imaging device and the rearview auxiliary imaging device, and is convenient for a car driving driver to expand the observation visual fields of the front original lane, adjacent lanes and the road condition; the problem that a car body frame between frontal car glass and side car glass causes the visual blind area to the driver is solved. The invention also provides a visual field expanding method for the car driver. A fuzzy PID (Proportion Integration Differentiation) control system is adopted for the control method; the direct control on the system is completed by a parameter controllable type PID controller; not only are the visual field expanding system and the visual field expanding method for the car driver simple and practical, but also the response speed is fast, the overshoot is small, and the control effect is good.

Description

technical field [0001] The invention relates to a rear view system of a car door, in particular to a device for expanding a driver's field of vision and a method for expanding a driver's field of vision. Background technique [0002] At present, vehicles running on roads at home and abroad cannot expand and observe the current lane, adjacent lanes and the vehicle conditions in front of the car in traffic light areas at intersections, road traffic congestion areas, and slow-moving traffic sections. and road conditions; some drivers can only rely on turning the steering wheel left and right to observe the road conditions ahead, and try to merge, intersect, and overtake by chance, which will cause unnecessary traffic jams and accidents; some drivers will get off the car in violation of regulations To observe, if the driver cannot get out of the car to observe in bad weather such as wind, rain, snow, etc., some drivers blindly wait in the car for the vehicle to break down, so th...

Problems solved by technology

[0003] The present invention designs and develops a vehicle driver's field of vision expansion system, which is equipped with a horizontal auxiliary mirror and a vertical auxiliary mirror and together with the main mirror forms a blind area and integrates the rearview mirror, which expands the front and rear side vision of the car, and allows the driver to observe more road conditions. A pair of eyes, which effectively solves the problem of blind spots in the driver's field of vision
