Abstract

The embodiment of the invention discloses a steering adjustment method, system, device and storage medium of an exterior rearview mirror. When it is determined that the driver is driving the current vehicle, collect the driver's eye point position, obtain the current steering information of the current vehicle, and determine whether the current vehicle is in the active steering state according to the current steering information and eye point position, if the current vehicle is in the active steering state , calculate the target position of the exterior rearview mirror according to the eye point position and the current steering information, and adjust the position of the exterior rearview mirror to the target position, which solves the problem of the exterior rearview mirror in the process of turning and changing lanes in the prior art. The position of the lens remains unchanged, resulting in the problem of visual blind spots for the driver, and achieves automatic calculation of the target position of the exterior rearview mirror based on the eye point position and current steering information, and automatically adjusts the position of the exterior rearview mirror to the target position The purpose is to achieve the effect of increasing the driver's visual field observation range when the vehicle is turning, so as to improve driving safety.

Description

technical field [0001] Embodiments of the present invention relate to automobile intelligent technology, and in particular to a steering adjustment method, system, device and storage medium of an exterior rearview mirror. Background technique [0002] In recent years, with the development of automobile technology, automobiles have become a very common means of transportation. During the driving process of the car, the user often performs operations such as turning, changing lanes, and turning around by observing the rearview mirror. [0003] In the field of traditional automobiles, the position of the exterior rearview mirror lens remains unchanged relative to the exterior rearview mirror housing when the car is turning and changing lanes. During the process of turning and changing lanes, the driver needs to use the exterior rearview mirror to observe the rear field of view to further increase. If the position of the exterior rearview mirror lens remains unchanged, the driv...
