Assuming that the passenger sits below point C, because the coordinates of point E and point C are known, a right triangle is created, and a trigonometric function is used, where [ EF length ] ═ EC length ] × cos (d) in the figure, and at this time, the horizontal distance between the driver and the passenger from the coordinate E can be calculated, and thus the anteroposterior position of the shoulder can be calculated
Continuing to establish a right triangle, when the length of EF in the graph is known, calculating the FG length in the graph, and using a trigonometric function [ FG length ] - [ EF length ] × TAN (H); the [ CF length ] + [ FG length ] - [ height of the shoulder from the ceiling ], and the height of the shoulder from the ceiling can be determined.
Since the horizontal distance and height of the shoulders are known, the coordinates of the shoulders can be obtained in a coordinate system established with the in-vehicle camera as the origin.
In this embodiment, the shoulder coordinates are obtained and it is known that the belt guide should be fixed at the position 3-5CM directly above the shoulder of the human body as the optimal position, so that the optimal theoretical guide position, i.e. the position 3-5CM directly above the shoulder coordinates of the human body, can be known.
And acquiring the current position of the guide plate, wherein if the current position of the guide plate is just 3-5CM above the shoulder coordinate of the human body, the adjustment is not needed, and if the current position of the guide plate is deviated, for example, if the current position of the guide plate is just 1CM above the shoulder coordinate of the human body, the adjustment is needed to be carried out to 3-5CM above the shoulder coordinate of the human body.
In this embodiment, the guiding plate adjusting mechanism is a motor, referring to fig. 2 and 3, for a fixed vehicle model, the installation position of the seat belt guiding plate and the adjustment of the seat belt guiding plate motor are known, and both factory and motor calibration are already done in software, when a passenger is in the position of fig. 2, the passenger may feel uncomfortable or the guiding plate 1 is not in the optimal position, the guiding plate 1 can be adjusted to the appropriate position, i.e., the position shown in fig. 3, and at this time, the seat belt guiding plate can be adjusted up and down, left and right according to the coordinates of the shoulders, so as to be adjusted to the optimal position.
It can be understood that the guide plate adjusting mechanism can also be an electric push rod, and the moving end of the electric push rod is connected with the guide plate and can push the guide plate to move on the guide rail, so that the position of the guide plate can be adjusted.
