Embodiment 1

[0048] An embodiment of the present invention provides a method for automatically adjusting the field of view of a rearview mirror, see figure 1 , the method includes: after detecting the door opening signal, obtaining the biological parameters of the driver in real time; judging whether the driver's information is stored, and if the driver's information is stored, obtaining the corresponding adjustment parameters, according to the The rearview mirror is adjusted according to the above adjustment parameters; if the driver’s information is not stored, the general model is called according to the biological parameters to obtain the driver’s pre-adjustment parameters, and the rearview mirror is pre-adjusted according to the pre-adjustment parameters; According to the sitting posture data of the driver after sitting in the driving seat, precise adjustment parameters are generated according to the first predetermined rule according to the sitting posture data, and the rearview mirro...

Embodiment 2

[0071] Generally speaking, after the rearview mirror is adjusted, the driver generally does not adjust it during driving, but under different road conditions, the information that the driver hopes to obtain from the rearview mirror is different. For example, in congested and slow-speed road conditions, The driver pays more attention to the state of the adjacent vehicles on the left and right sides, avoiding accidents such as collision with his own vehicle, and requires an increase in the proportion of the body in the rearview mirror image; while in fast and smooth traffic conditions, there are fewer adjacent vehicles, and the driver pays more attention to it. For distant vehicles in adjacent lanes, the proportion of the body in the rearview mirror image is required to be reduced. Therefore, the embodiment of the present invention also provides a method for automatically adjusting the field of view of the rearview mirror, in which the automatic adjustment of the rearview mirror ...

Embodiment approach

[0074] According to another embodiment of the present invention, when the trigger condition that the driving speed of the vehicle is greater than the threshold is detected, the rearview mirror is automatically adjusted according to the following second preset rules:

[0075] In the left outer rearview mirror, the car body occupies 1 / 5 of the total width of the rearview mirror, and in the remaining 4 / 5 of the left half, the sky above the horizon occupies 2 / 3, and the ground below the horizon occupies 1 / 3; The horizon is at a lower position;

[0076] The body of the right outer rearview mirror accounts for 1 / 5 of the total width of the rearview mirror, and of the remaining 4 / 5 of the right half, the sky above the horizon occupies 2 / 3, and the ground below the horizon occupies 1 / 3; The horizon is lower.

[0077] The field of view of the interior rearview mirror is aligned with the rear window, and the horizon is maintained at the center of the mirror.

[0078] When the vehicle ...

Abstract

The invention discloses a method for automatically adjusting a visual field of a rearview mirror. The method comprises the steps that a biological parameter of a driver is acquired in real time after a door opening signal is detected; whether the information of the driver is stored or not is determined, if the information of the driver is stored, the corresponding adjustment parameter is obtained, and the rearview mirror is adjusted according to the adjustment parameter; if the information of the driver is not stored, a general model is invoked according to the biological parameter to obtain the pre-adjustment parameter of the driver, and the rearview mirror is adjusted according to the pre-adjustment parameter; the sitting posture data after the driver sits in the driving position is obtained, the precise adjustment parameter is generated according to the sitting posture data according to a first predetermined rule, and the rearview mirror is adjusted according to the precise adjustment parameter; and during the vehicle travelling process, the rearview mirror is dynamically adjusted according to at least one of second preset rules according to at least one trigger condition. According to the method for automatically adjusting the visual field, the rearview mirror can be quickly and intelligently adjusted, and the driving safety is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobile intelligent driving, in particular to a method and device for automatically adjusting the field of view of a rearview mirror. Background technique [0002] During the current vehicle driving process, the driver observes the situation of vehicles coming from the rear by observing the three rearview mirrors arranged on the left and right sides of the vehicle body and in the cockpit, so as to safely perform operations such as driving, merging, and turning. Affected by parameters such as the field of view size and angle of the rearview mirror, the driver's height, interpupillary distance and other parameters, as well as the traffic environment and natural environment where the vehicle is driving, the fixed rearview mirror cannot meet the needs of safe driving, and the current automatic The method of adjusting the rearview mirror is too simple to operate, and it is not smart en...
