A kind of automobile rearview mirror and control method
Technical field
The present invention relates to automobile technical fields, more particularly to a kind of automobile rearview mirror and control method.
Background technology
Currently, the rearview mirror of automobile is plane, visible angle is little, and there are certain blind areas.Driver is expert at
When sailing vehicle, usually the situation of road can be confirmed by changing door mirror angle, but driven rearview mirrors control device at present
It is generally located near door handle, driver is not difficult to drive on one side in the process of moving, after being adjusted on one side according to driving condition
Mirror angle, driver cannot flexibly grasp the field range of rearview mirror and generate rear view mirror blind zone, so to a certain extent
It can influence traffic safety.
In the prior art, it to overcome rear view mirror blind zone, is typically employed in outside rear-view mirror and installs spherical mirror additional or take blind spot
The work of vehicle in check frequency.Using on the former minute surface of outside rear-view mirror, convex mirror, spherical mirror or prism etc. are installed additional
Additional mirror sheet mode is insufficient to make up the visual field, the disadvantage is that additional eyeglass makes observed scene that gross distortion, convex mirror, ball occur
Face mirror or prism etc. also can not flexible modulation to cope with the complex road condition in driving process, and the small sight of minute surface of additional eyeglass
Difficulty is examined, while but also former eyeglass usable area becomes smaller and influences normal use, additional eyeglass is also easy to fall off.Using blind spot
Detection technique, has detected whether vehicle in blind area, but when vehicle traveling tunnel or it is closer from metope when, system
It can be mistakenly considered car, and cried wolf.
Therefore, how to solve in the prior art rearview mirror can not in driving flexible modulation position and generate asking for blind area
Topic, is those skilled in the art's question of common concern.
