Description

Intelligent combined type vehicle-mounted rearview mirror system Technical Field The utility model relates to the technical field of automobile accessories, in particular to an intelligent composite vehicle-mounted rearview mirror system. Background The vehicle rearview mirror is taken as an important component of an automobile safety system, and the performance quality of the vehicle rearview mirror directly influences the driving safety. The traditional external rearview mirror adopts a single-curvature spherical mirror structure, and realizes rear view observation based on a physical optical reflection principle, but the basic framework of the external rearview mirror gradually shows various technical limitations when dealing with complex traffic environments. In terms of optical performance, conventional rearview mirrors have a significant field of view blind area due to the fixed curvature design. This blind area coverage covers the critical area of the adjacent lane, making it difficult for the driver to directly observe the side rear vehicle when changing lanes or turning. The existing improvement scheme is mostly dependent on frequent turning of a driver or additional installation of auxiliary devices, but the former influences the concentration degree of driving, and the latter is easy to cause visual information interference. Although some vehicles employ electronic auxiliary systems, the usability of the electronic auxiliary systems is still limited by the problems of high false alarm rate, information feedback delay and the like. In terms of environmental adaptability, the traditional mirror reflection mechanism has the defects that 1) the glare reflection phenomenon of a rear vehicle high beam is serious during night driving, particularly the visibility is obviously reduced in a rainy and foggy weather, 2) the mirror surface fog forming speed is high in a low-temperature and high-humidity environment, the response of the traditional defogging scheme is delayed, and 3) the imaging definition is influenced by mirror surface residues in the rainy and snowy weather. The existing electronic improvement scheme attempts to integrate the sensing module, but often damages the original structure of the rearview mirror or reduces the effective observation area of the mirror surface. The prior art scheme mainly has the contradiction that the mechanical rearview mirror is difficult to be compatible with the modern electronic sensing technology, and the pure electronic scheme cannot keep the reliable optical observation function. Particularly in the event of abnormal power supply to the system, failure of the electronic device may cause a safety hazard of completely losing the rearview capability. These technical drawbacks lead to the driver facing multiple operational burdens under complex road conditions, both to process conventional specular reflection information and to cope with interactive feedback of electronic devices, and this multitasking mode is prone to distraction. Research shows that the operation load can obviously prolong the stress response time of a driver, and directly influence the driving safety in a high-speed driving scene. Therefore, development of a novel rearview mirror system with optical observation reliability, electronic perception accuracy and environmental adaptability has become an important research direction for improving the active safety technology of vehicles.
