In order to clearly understand the technical means of the present application, first, the means of the prior art will be described in detail. In the prior art, the driver usually adjusts the angle of the rearview mirror manually, but many drivers do not meet the specifications when adjusting manually, for example, only considering reducing the blind spot. However, if excessive attention is paid to the blind spot area, it may not be possible to determine the relative position of the vehicle behind and the vehicle. Therefore, if the driver manually adjusts the rear-view mirror, the rear-view mirror cannot be adjusted accurately and quickly to the proper angle, which may raise some safety concerns while driving, and the driver.

The mirror control device 11 is used to control the rear-view mirror 12 of the automobile, and the rear-view mirror control device 11 is an electronic control unit (ECU) of the automobile or a separately provided control device. The positioning device 10 may be a sound source positioning device based on a microphone array, a positioning device based on image acquisition, an ultrasonic positioning device, or the like. The rear-view mirror control device 11 determines the driver's head position information via the positioning device 10, and further determines the driver's eye position information based on the head position information and the acquired five-government ratio parameter. Finally, the target angle of the rear-view mirror is determined, and the rear-view mirror 12 is adjusted based on the target angle. The rearview mirror 12 may include an inner rearview mirror and / or an outer rearview mirror.

Hereinafter, the rearview mirror adjustment procedure will be described in detail by combining specific examples.

The first embodiment of the present application provides a method of adjusting the rear-view mirror, and FIG. 2 is a flowchart of the method of adjusting the rear-view mirror provided in the embodiment of the present invention.

In addition, since many positioning devices such as a microphone array and an ultrasonic positioning device cannot directly determine the eye position of the driver like an image collecting device, the head position of the driver and the five officials are followed according to the above procedure. After determining the ratio parameter first, it is necessary to further determine the driver's eye position information based on the head position information and the five-government ratio parameter, but the driver's eye position is directly determined using the image acquisition device directly. It is possible to save a great deal of cost and ensure high accuracy.

In S204, the target angle of the rear-view mirror is determined based on the eye position information and the rear-view mirror adjustment model set in advance.
