Abstract

PURPOSE:To make it unnecessary to do any adjustment of a side mirror by providing a function to automatically adjust the inclination of the side mirror based on the result of detecting the horizontal/vertical distances of an eye point to the mirror. CONSTITUTION:A distance Xa is detected by a slide position detector 25, and an angle theta1 is detected by an angle detector 26. These signals are sent to a control device 27 to obtain the horizontal distance L of an eye point 3. Next, an inclination angle theta2 of a room mirror 28 is detected by an angle detector 30, and a signal from this detector 30 is arithmeticaly processed by the control device 27 to obtain a vertical distance H. Based on the horizontal and vertical distances L and H, the control device 27 controls an angle adjust mechanism 31 for a side mirror 1 to set the horizontal angle a and the vertical angle b of the side mirror. In this way, for adjustment of the mirrors, the driver has to adjust the room mirror only, with no need to adjust the side mirror.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side mirror control device, and particularly to an 1ilJ control device that can automatically adjust the side mirror based on the seated position and inclination angle of the driver and the angle of the rearview mirror. It is something.

Conventionally, the side mirrors were electrically driven, and by manually operating the operating member of the control panel installed on the inside of the vehicle, the angle of inclination of the side mirrors could be set to the state that best suited the driver. has been proposed.

However, with this type of side mirror control device, the driver has to operate each of the operating members one by one when seated in the seat, which requires time and effort, and it is difficult to perform such operations while driving. This has the disadvantage of compromising driving safety.

The purpose of the present invention is to detect the driver's eye point based on the front and back position of the seat, the inclination angle of the seat back, and the angle of the rearview mirror, and to determine the horizontal and vertical angles from the reference position of the side mirror according to the detection results. The above-mentioned drawbacks are eliminated by making it possible to automatically adjust the angle, and will be described in detail below using examples.

First, the outline of the side mirror control device according to the present invention will be explained. In FIG. 1, the axle axis of the side mirror 1 is adjusted as shown in FIG. For example, in FIG. 2, when the eye point 3 moves toward the rear and the horizontal distance increases from Ll to Ll, the angle a with respect to the line segment 5 perpendicular to 4 is adjusted. is adjusted so that it gradually becomes smaller. This allows light 6 from the left and right rear sides of the vehicle (rear side conditions) to always enter the eye point 3.3a of the driver 2.

Also, the vertical pressure 11 between the eye point 3 and the side mirror 1 is
The angle of inclination of the side mirror 1 in the vertical direction is adjusted in accordance with 1H.

That is, if the eye point 3 changes from a high position to a low position 36 as shown in FIG. t changes so that it becomes smaller. This allows the light 6 from the rear side to always enter the eye point 3 side.

Therefore, the present invention provides the above-mentioned horizontal distance of eye point 3,
This system detects the vertical distance H and automatically adjusts the inclination angle of the side mirrors based on this detection result. , and when the horizontal distance changes greatly from L1, the horizontal angle a is set to become smaller. Also, when eye point 3 becomes lower as shown in Figure 3 and changes from vertical distance III Hl to H&,
The vertical angle of the side mirror 1 is set small.

In FIG. 1, the seat 20 has a seat cushion section 21.
and a seat back portion 22, the angle θ1 of the seat back portion 22 can be adjusted by a reclining device 23. Further, the seat cushion fIB21 can be adjusted in its longitudinal position by the slide mechanism 24. That is, the slide mechanism 24
Thus, the distance Xa between the reference position Ca, which is a predetermined distance C away from the side mirror 1, and the rear end of the seat cushion portion 21 can be adjusted. On the other hand, the horizontal distance Xb between the rear end position of the seat cushion part 21, that is, the position where the reclining device 23 is attached, and the head of the seat back part 20 is approximately h-c03θ1 (h is the length of the seat back part 2o) It is expressed as Therefore, the horizontal distance of eye point 3 is C+Xa+Xb-Cm (
Cm is the distance between the eye point 3 and the head).

The above Xa is detected by a slide position detector 25 built into the slide mechanism 24, and the angle θ1 is detected by an angle detector 26 built into the reclining device 23, and the signals from these detectors 25 and 26 are The horizontal distance of the eye point 3 is calculated by the control device 27, which executes the above equation.

Next, the vertical pressure N between the side mirror 1 and the eye point 3
To determine H, the inclination angle θ2 of the rearview mirror 28 is detected. That is, normally, when the eye point 3 moves downward and the vertical distance H becomes shorter, the angle θ2 between the rearview mirror 28 and the horizontal line segment 29 becomes smaller, and conversely, the eye point 3 moves upward and the vertical pressure MH decreases. The driver adjusts the angle θ2 at the start of work so that the longer the angle θ2 becomes, the larger the angle θ2 becomes. Therefore, the vertical distance H is proportional to the inclination angle θ2 of the rearview mirror 28, and the vertical pressure jlliH changes depending on the magnitude of θ2. Therefore, in the present invention, the angle detector 3o detects the inclination angle θ2 of the rearview mirror 28.
The signal from this detection 830 is processed by the control device 27 to calculate the vertical pressure MH. The control device 27 calculates the horizontal distance and the vertical distance 111.
The angle adjustment mechanism 31 of the side mirror 1 is controlled based on the size of 1H, and the horizontal angle a and the vertical angle of the side mirror 1 are set as described above.

Therefore, when the horizontal distance of the eye point 3 changes due to a change in the longitudinal position of the seat 20 or the inclination angle of the seat bank section 22, the slide position detector 25. Based on the output signal from the angle detector 26, the control device 27 automatically detects the horizontal distance of the eye point 3 at that time,
The angle adjustment mechanism 31 is controlled based on this horizontal distance to adjust the horizontal angle a of the side mirror 1. In addition, by adjusting the inclination angle of the seat bank portion 22, or by having the driver 2 with a different sitting height seated, the driver can adjust the rearview mirror 28 to the most appropriate angle θ2 for the driver.
When the angle θ2 is operated, the angle θ2 is detected by the angle detector 30 and sent to the control device 27.The control device 27 calculates the vertical distance H based on the angle θ2, and adjusts the angle adjustment mechanism 31 based on this vertical distance H. It controls the vertical angle of the side mirror 1. Therefore, the angle of the side mirror 1 can be adjusted by simply adjusting the rearview mirror 28 while the driver is seated on the seat 20, so that no operation is required to adjust the side mirror 1.

The control device 27 includes a storage device 50 as shown in FIG. 4, for example, and stores horizontal angle signals and vertical angle signals of different sizes in a horizontal angle signal storage address 51 and a vertical angle signal storage address 52 of the storage device 50. These signals may be stored and read out in correspondence with the signals from the detectors 25, 26, 30, and output to the angle adjustment mechanism 31. Further, the detectors 25, 26, and 30 may have built-in oscillators to generate pulses having a frequency that corresponds to the position and angle.
