Description

AUTOMATIC APPARATUS FOR ADJUSTING THE DIRECTION AND ANGLE OF THE SIDE MIRRORS IN A VEHICLE ACCORDING TO THE ROTATIONAL DIRECTION AND ANGLE OF THE STEERING WHEEL
The present invention relates to an automatic apparatus for adjusting the direction and angle of the side mirrors in a vehicle according to the rotational direction and angle of the steering wheel wherein a sensor that senses the direction or angle of the steering wheel, a motor that adjusts the rotational angle of the mirror, and a controller that drives and controls said motor based on the input of the direction and angle sensed by said sensor are included.
Generally the side mirrors that are attached to vehicles help the drivers recognize easily the vehicles or people approaching from the vehicle’s side or rear by providing the drivers with the vehicle’s side or real view.
Here, by combining a motor into said side mirror and installing a control switch inside the vehicle in order to adjust the reflection angle of the side mirrors that are attached to the vehicle’s outside, it has been possible to adjust freely the reflection angle of the side mirror also from the vehicle’s inside according to the driver’s condition and the length or width of a vehicle.
Therefore, it has been possible to reduce the causes of accidents because the driver of a vehicle could easily recognize the vehicles in other lanes approaching from the rear.
However, for those vehicles with a fixed reflection angle of the side mirror, when making a lane change, turning to the right or left, or negotiating a curve, a blind spot where a vehicle approaching into the inner lane cannot be recognized occurs, which has been a problem to cause frequent fender benders when said blind spot is not recognized.
The present invention has been made in view of the above described problems, and it is an object of the present invention to minimize the occurrence of the consequential accidents by preventing the blind spot that occurs when making a lane change, turning to the right or left, or negotiating a curve.
The automatic apparatus of the present invention for adjusting the direction and angle of the side mirrors in a vehicle according to the rotational direction and angle of the steering wheel includes a sensor that senses the direction or angle of the steering wheel, a motor that adjusts the rotational angle of the mirror, and a controller that drives and controls said motor based on the input of the direction and angle sensed by said sensor, and has a feature that, when the rotational angle of the steering wheel is referred to as A and the rotational angle of said mirror is referred to as B, the ratio of B to A for an angle not exceeding a predetermined angle is bigger than the ratio of B to A for an angle exceeding the predetermined angle.
According to this configuration, the side mirror is automatically adjusted according to the rotational direction and angle of the steering wheel.
Furthermore, the automatic apparatus of the present invention for adjusting the direction and angle of the side mirrors in a vehicle according to rotational direction and angle of the steering wheel includes an additional switch that can select a rotational angle of the mirror for a predetermined rotational angle of the steering wheel.
According to this configuration, the driver of a vehicle can conveniently adjust the rotational angle of the side mirror that rotates in response to the rotational direction and angle of the steering wheel according to the length or width of a vehicle, or the driver’s condition.
The above-explained automatic apparatus for adjusting the direction and angle of the side mirrors in a vehicle according to the rotational direction and angle of the steering wheel has the following advantages.
An advantage of the present invention is that the occurrence of the consequential fender benders can be minimized by preventing the blind spot that occurs when making a lane change, turning to the right or left, or negotiating a curve because the side mirror of a vehicle is automatically adjusted according to the rotational direction and angle of the steering wheel.
Furthermore, because the present invention includes an additional switch that can select a rotational angle of the mirror for a predetermined rotational angle of the steering wheel, the driver can adjust conveniently the rotational angle of the side mirror that rotates in response to the rotational direction and angle of the steering wheel according to the length or width of a vehicle, or the driver’s condition.

Hereinafter, the preferred embodiment of the present invention will be explained in detail with reference to the accompanying drawings.
For reference, please refer to the aforedescribed conventional art for those configurations of the present invention that are the same as in the conventional art and the separate detailed explanation for such configurations is to be omitted herein.
FIG. 1 is a general configuration diagram of an automatic apparatus of the present invention for adjusting the direction and angle of the side mirror of a vehicle according to the rotational direction and angle of the steering wheel.
FIG. 2 is a drawing showing the state in which the mirror is operated when the steering wheel rotates to the right in the present invention.
FIG. 3 is a drawing showing the state in which the mirror is operated when the steering wheel rotates to the left in the present invention.
FIG. 4 is a graph showing the ratio of the rotational angle of the mirror to the rotational angle of the steering wheel.
The automatic apparatus for adjusting the direction and angle of the side mirror in a vehicle according to the rotational direction and angle of the steering wheel of the present invention comprises; a sensor(200) that senses the direction or angle of the steering wheel(100), a motor(300) that adjusts the rotational angle of the mirror and a controller(400) that drives and controls said motor(300) based on the input of the direction or angle that is sensed by said sensor(200).
Here, it is desirable to make said sensor(200) comprise a sensor sensing the direction of the steering wheel and a sensor sensing its angle.
The description of the operation of the present invention with the aforesaid configuration is as follows.
First of all, after the rotational direction or rotational angle of the steering wheel(100) is sensed by the sensor(200), the signal is sent to the controller(400) through the output cable(210).
Said controller(400) sends the control signal that determines the adjustment amount of the angle of the right or left side mirror(520,510) through the power cable(302,301) to the motor(300) that rotates said right or left side mirror(520,510) respectively.
It is desirable for said motor(300) to be of a step motor with gear formed on the circumference of the rotating shaft that rotates in both directions.
Here, the adjustment plate(310) that is engaged with the gear of said motor(300) and moves back and forth as said motor(300) rotates forward or backward is connected to one end of the right or left side mirror(520,510).
It is desirable that said right or left side mirror(520,510) and said adjustment plate(310) are connected to each other by a separate connection means(not shown) such as a rotating shaft.
Therefore, if said motor(300) rotates forward or backward according to the rotational direction or rotational angle of the steering wheel(100) that is recognized by the controller(400), said side mirror(520,510) that is connected to said adjustment plate(310) rotates forward or backward on the support shaft(550) that supports said side mirror(520,510) as the adjustment plate(310) that is connected to the gear of said motor(300) moves back and forth.
Hereinafter, the reference numeral(102) in the drawing is the center line in the state that the right and left tires(610,620) of a vehicle are in perfect parallel with the right and left sides of the vehicle body(600) while the reference numeral(101) in the drawing is the upper center point of the steering wheel(100) of a vehicle.
As shown in Fig. 2, if the driver of a vehicle rotates during driving the steering wheel(100) to the right with reference to the center line(102) in order to make a lane change to the right or turn to the right, the left side mirror(520) does not rotate, but the right side mirror(510) rotates to the left i.e. counterclockwise.
For the explanation of the above with some examples, assuming the position ⑥ as the state that said center line(102) is in line with the center point(101) of the steering wheel(100) so that the right and left tires(610,620) of a vehicle are in parallel with the right and left sides of the vehicle body(600), the position ⑦ as the state that said steering wheel(100) rotates 5°to the right, the position ⑧ as the state that said steering wheel(100) rotates 30°to the right, the position ⑨ as the state that said steering wheel(100) rotates 90°to the right, and the position ⑩ as the state that said steering wheel(100) rotates 180°to the right, and also assuming in the state that the right and left tires(610,620) of vehicle are in parallel with the right and left sides of the vehicle body(600), the position ① as the state that the driver of a vehicle has adjusted the right or left side mirror(520,510) through a separate switch (not shown) according to the length or width of a vehicle, or the driver’s condition, the position ② as the state that the mirror rotates 10°to the left from said state ①, the position ③ as the state that the mirror rotates 15°to the left, the position ④ as the state that the mirror rotates 20°to the left, and the position ⑤ as the state that the mirror rotates 25°to the left, the right side mirror(510) is at the position ① if the center point(101) of the steering wheel(100) is at the position ⑥.
Furthermore, if the center point(101) of the steering wheel(100) rotates to the right with reference to the center line(102) and is at the position ⑦, the right side mirror(510) is at the position ②.
Furthermore, if the center point(101) of the steering wheel(100) rotates to the right with reference to the center line(102) and is at the position ⑧, the right side mirror(510) is at the position ③.
Furthermore, if the center point(101) of the steering wheel(100) rotates to the right with reference to the center line(102) and is at the position ⑨, the right side mirror(510) is at the position ④.
Furthermore, if the center point(101) of the steering wheel(100) rotates to the right with reference to the center line(102) and is at the position ⑩, the right side mirror(510) is at the position ⑤.
Here, it is desirable to make the right side mirror(510) rotate no more even when said steering wheel(100) rotates to the right over 180°past the position ⑩.
On the other hand, in the state that both right and left tires(610,620) have turned to the right(i.e. the state that the center point(102) of the steering wheel(100) is positioned at ⑩), if said steering wheel(100) rotates in the reverse direction i.e. to the left, the right side mirror(510) rotates to the position ① from the position ⑤, and if the center point(101) of the steering wheel(100) reaches the position ⑥ and the center point(101) is in line with the center line(102), the right and left tires(610,620) are in the state to be in parallel with the sides of the vehicle body(600).
Here, again if the steering wheel(100) rotates to the left and the center point(101) moves to the left past the center line(102), the right side mirror(510) is fixed at the position ① and the left side mirror(520) rotates to the right i.e. clockwise.
On the other hand, because the operation principle of the left side mirror(520) is identical to the one of the right side mirror(510) which has been explained in the above, the detailed explanation for the left side mirror is to be omitted herein.
As described in the above, the rotational angle of said right side mirror(510) is proportional to the rotational angle of said steering wheel(100) and produced in accordance with the angle that is pre-programmed in the controller(400).
In other words, as shown in Fig. 4, for the rotational angle (A) of the steering wheel and the rotational angle (B) of said mirror, the ratio of B to A for the rotational angle (A) of the steering wheel not exceeding 30°is bigger than the ratio of B to A for the rotational angle (A) of the steering wheel exceeding 30°as the rotational angle (A) of said steering wheel increases.
In other words, for the rotational angle (A) of the steering wheel not exceeding 30°, the rotational angle (B) of the side mirror is made bigger than the rotational angle (A) of said steering wheel while for the rotational angle (A) of the steering wheel exceeding 30°, the rotational angle (B) of the side mirror is made much less than the rotational angle (A) of said steering wheel.
In the above, 30°was mentioned as a reference for the rotational angle of the steering wheel(100) because the lane change is fully possible with the adjustment of the rotational angle of the steering wheel(100) within 30°when making a lane change during driving on the normal road with no steep curve or negotiating a relatively smooth curve.
On the other hand, in case of very small rotation of the rotational angle of the steering wheel(100) with less than 5°(for example, a little trembling that occurs while driving on the straight road), it is desirable to make the side mirrors(520,510) not rotate.
Here, the rotational angle of the right and left side mirrors(520,510) can be adjusted to the same rotational angle of the right and left tires(610,620) that turn as said steering wheel(100) rotates.
On the other hand, in the present invention, an additional switch(450) is installed, which the driver of a vehicle can use to select a phase that can reduce the rotational angle of the side mirrors(520,510) for a rotational angle of the steering wheel(100) and a phase that can increase the rotational angle of the side mirrors.
Therefore, when said steering wheel(100) rotates 30°to the right or left, the driver of a vehicle can reduce or increase the rotational angle of the right or left side mirror(520,510) to 10°or 30°.
For example, using said switch(450), the driver of a vehicle can reduce or increase selectively the corresponding rotational angle of the side mirror(520,510) for a predetermined rotational angle of the steering wheel(100) after selecting a range of the rotational angle of the right or left side mirror(520,510) that can be various angles such as 10°to 30°.
Here, it is desirable to form said switch(450) inside the vehicle so that the driver of a vehicle can operate it conveniently from the inside of the vehicle.
Therefore, it is possible to make the rotational angle of the side mirror relatively bigger for a small rotational angle of the steering wheel or make the rotational angle of the side mirror relatively smaller for a big rotational angle of the steering wheel.
For example, when the steering wheel(100) rotates comparatively small to the right to the position ⑦, the driver of a vehicle can make the right side mirror(510) rotate to the left so much to the position ⑤, and relatively when the steering wheel(100) rotates comparatively big to the right to the position ⑩, the driver of a vehicle can make the right side mirror(510) rotate to the left so little to the position ②.
On the other hand, the switch(450) makes it possible to simply reduce or increase the corresponding rotational angle of the side mirror for a predetermined rotational angle of the steering wheel(100), and also can be configured in such a way that the rotational angle of said side mirror can be selected to be one of the positions ① to ⑤ according to the rotational angle of said steering wheel(100).
Therefore, using said switch(450), the driver of a vehicle can conveniently adjust the corresponding rotational angle of the side mirror(520,510) in response to the rotational angle of the steering wheel(100) according to the length or width of a vehicle or the driver’s condition.
Thus, the apparatus of the present invention for automatically adjusting the direction and angle of the side mirrors in a vehicle according to the rotational direction and angle of the steering wheel can minimize the occurrence of the consequential fender benders by preventing the blind spot from occurring when making a lane change, turning to the right or left, or negotiating a curve because the side mirrors in the vehicle are automatically adjusted according to the rotational direction and angle of the steering wheel(100).
Although the present invention herein has been described in the above with reference to the preferred embodiment, it will be apparent to those skilled in the art that various changes and modification may be made to the above described embodiments, without departing from the scope and spirit of the present invention as disclosed in the accompanying claims.
As described above, it is appropriate to use the automatic apparatus for adjusting the direction and angle of the side mirrors in a vehicle according to the rotational direction and angle of the steering wheel in accordance with the present invention in order to sense easily and quickly the side and rear views of a vehicle through both right and left side mirrors that are attached to the vehicle especially when making a lane change, moving or turning to the right or left, or negotiating a curve during driving, thereby improving the safety and preventing fender benders.
