Description
Technical Field
The invention belongs to the technical field of automobile electronic and control systems, and particularly relates to an electronic rearview mirror visual field display control system and a using method thereof.
Background
With the continuous innovation of automobile technology, the traditional mechanical rearview mirror is gradually unable to meet the requirements of modern driving in terms of functionality and safety. The traditional rearview mirror is limited by the physical structure and the installation position, has a limited visual field range, and is easy to form a blind area particularly in a narrow space or under complex road conditions, so that driving risks are increased. To overcome the limitations of conventional rearview mirrors, electronic rearview mirrors have been developed.
The electronic rearview mirror captures images around the vehicle through the camera and transmits the images to the display screen in real time for the driver to watch, so that the visual field range is greatly expanded, the blind area is eliminated, and the existing electronic rearview mirror visual field display control system still has some defects in the aspects of module integration, data transmission and function perfection. For example, some systems have resulted in delays or distortions in image display due to poor communication between modules or insufficient data processing capabilities; some systems have multiple functions, but are complex to operate and not humanized enough, and the use experience of a driver is affected.
However, existing electronic rearview mirror systems still suffer from a number of deficiencies. For example, some systems are equipped with only a single camera, and cannot provide all-round visual field information, and the problem of blind areas in a narrow road section or in reverse warehouse entry: when a vehicle runs on a narrow road section or needs to be backed up and put in storage, a driver may encounter a problem that a lateral view is blocked due to a fixed position and angle of a conventional rear view mirror. This is because the mirror surface size, shape and installation position of the rear view mirror are fixed, and cannot be flexibly adjusted according to the driving environment of the vehicle and the needs of the driver. The driver may increase the risk of collision when turning, changing lanes or reversing a car because the side and rear conditions cannot be accurately observed; field of view blurring problem in severe weather conditions: under severe weather conditions such as rainy days, foggy days or nights, the mirror surface of the traditional rearview mirror is easily affected by rainwater, fog or insufficient light at night, so that the visual field of a driver is blurred. Rainwater or fog can be attached to the mirror surface to form a water film or fog layer, so that the sight of a driver is blocked; and the light rays at night are insufficient, so that the light rays reflected by the mirror surfaces are weakened, the driver is difficult to see the situation behind, the driving safety is influenced, and the safety accident is easy to occur.
These examples all illustrate the problem of limited field of view and susceptibility to environmental impact in some cases of conventional mechanical rearview mirrors, and electronic rearview mirrors as a new type of car safety device, which can provide a wider field of view, a clearer image display, and more function choices by combining a camera and a display screen, thereby solving these problems and improving driving safety. Accordingly, there is a need for improvements and innovations in electronic rearview mirror field of view display control systems to further enhance the performance and user experience of the system.
The present invention has been made in view of this.
