Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic rear-view mirror adjusting device for a vehicle, which automatically adjusts the angle of the mirror according to the inclination of the vehicle body.

[0002]

2. Description of the Related Art Conventionally, in vehicles such as passenger cars and trucks,
Since the visibility in the rear mirror changes depending on the seat height and the seating position of the driver, the angle of the mirror is changed each time the driver is seated to adjust the position so that it is easy to see.

[0003]

However, even if the vehicle is adjusted to a position that is easy to see, if the vehicle body tilts in the front-rear direction due to cargo being loaded on the vehicle, the field of view in the mirror, which was previously easy to see, also changes. The angle of the mirror has to be adjusted each time, and the side mirrors, which are sometimes provided on both sides of the vehicle body, have to be adjusted from the driver's cab, which makes the adjustment troublesome.

The present invention has been made in order to solve such a problem, and an object of the present invention is to provide an automatic rear mirror adjusting device for a vehicle, which automatically adjusts the angle of the mirror according to the inclination of the vehicle body. It is a thing.

[0005]

In order to achieve the above-mentioned object, the present invention provides a tilt sensor for detecting a tilt of a vehicle body which changes due to a change in a load or an occupant, and a tilt of the vehicle body before the change and a rear mirror. A control that stores the angle as an initial setting value, determines the lean of the vehicle body by comparing it with the lean of the vehicle body that is input from the lean sensor after the change, and changes the angle of the rear-view mirror according to the lean when the lean body is tilted. It is provided with a controller that outputs a signal and a mirror direction control motor that automatically adjusts the rear mirror to an optimum position by a control signal output from the controller.

[0006]

With the above configuration, when the inclination of the vehicle body changes with respect to the inclination of the vehicle body and the angle of the rearward mirror stored as the initial setting value due to loading and unloading of luggage, the rearview mirror of the rear body mirror is changed according to the changed inclination of the vehicle body. Since the angle is automatically adjusted to the optimum position, it is not necessary to adjust each time.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an automatic rear mirror adjusting device for a vehicle, and FIG. 2 is a flow chart showing the same operation.

In FIG. 1, reference numeral 1 denotes an inclination sensor (not shown) for detecting an inclination of a vehicle body, and a displacement sensor 2 for each suspension (not shown) elastically supporting each wheel.
Is provided, and the inclination of the vehicle body is detected from the displacement position of the suspension detected by these displacement sensors 2.

Reference numeral 3 in FIG. 1 is a controller composed of a computer. The inclination sensor 1 indicates the inclination of the vehicle body, the vehicle speed sensor 4 indicates the vehicle speed, and the mirror direction detecting sensor 5 is provided.
The angle of the rear-view mirror 6 is input, and a mirror direction control motor 7 for driving the rear-view mirror 6 is connected to the output side of the controller 3.

The controller 3 includes a storage unit for storing the relationship between the inclination of the vehicle body before the change and the angle of the rear mirror as an initial setting value, and the inclination and inclination sensor 1 of the vehicle body stored as the initial setting value. Based on the signals from the comparison control unit that compares the inclination of the vehicle body and the comparison determination unit, a control signal is sent to the mirror direction control motor so that the angle of the rear mirror is at the optimum position according to the changed inclination of the vehicle body. A control output unit for outputting is provided.

Further, in FIG. 1, 8 is a battery mounted on the vehicle body, 9 is a power switch, 10 is a mirror adjustment switch for adjusting the rearview mirror 6 by remote control, and 11 is a switch for activating an automatic adjustment device, which is normally automatic adjustment. The device is operated only when stopped to prevent malfunction, but the angle of the rear-view mirror 6 can be automatically adjusted by turning on the switch 11 even while traveling.

The operation will now be described with reference to the flow chart shown in FIG.
When the power switch 9 is turned on in step 1, step 102
Then, when the power switch 9 is turned off last time, the inside of the controller 3 is initialized to the angle of the rear-view mirror 6 stored in the memory of the controller 3. For example, if the car is stopped in an empty state,
The inclination of the vehicle body in the empty state and the angle of the rear mirror according to the inclination are stored as the optimum position and initialized.

Next, at step 103, it is judged if the mirror adjustment switch 10 is turned on.

That is, when a load is loaded while the vehicle is stopped, the driver notices that the vehicle body is tilted due to the load and the field of view of the rear-view mirror 6 is changed, and the mirror adjustment switch 10 is used to make an adjustment. It is determined whether the rear mirror 6 is adjusted by the mirror adjustment switch 10 because the driver has changed, and if so, the process proceeds to step 104, where the current angle of the rear mirror 6 is the sensor for detecting the mirror direction. 5 detected and read by the controller 3, then step 1
05, the inclination sensor 1 reads the inclination of the vehicle body at the time of loading. When the mirror adjustment is performed in step 103, the process proceeds to step 106.

In step 106, the vehicle speed is read by the vehicle speed sensor 4, and in step 107 it is determined whether or not the current vehicle speed is "0". This judgment is to prevent malfunction,
It is performed after detecting the vehicle speed for a certain period of time. When the vehicle speed is "0", the process proceeds to step 109, and when it is other than "0", the process proceeds to step 108.

In step 108, it is determined whether or not the switch 11 is on. If it is on, the process proceeds to step 109,
If it is off, the process returns to step 103.

At step 109, the inclination sensor 1 reads the inclination state of the vehicle body and the routine proceeds to step 110. In the case of YES in step 103, the inclination of the vehicle body read in step 105 is equal to the inclination in step 109.

In step 110, it is determined whether or not the inclination of the vehicle body before the change, that is, the initial set value in step 101 is compared to determine whether the inclination of the vehicle body has changed. If the vehicle body tilt has changed, the optimum angle of the rear mirror is calculated according to the vehicle body tilt that has been fluctuated based on the relationship between the vehicle body tilt stored as the initial setting value and the position of the rearview mirror. A control signal is output to the mirror direction control motor 7 based on the obtained value. In Step 111, Step 1
The rear mirror 6 is automatically adjusted to have an optimum angle by a control signal output from 10.

As a result, even if the inclination of the vehicle body changes due to the load, the position is automatically adjusted to a position that is easy to see, so that the driver does not have to adjust the load each time it is loaded and unloaded, so that the driver can concentrate on driving the vehicle. become.

The vehicle speed sensor 4 may be configured such that a magnet cable is rotated by a rotating cable for a vehicle speedometer and a change in the magnet is taken out as a voltage signal by a coil. The mirror direction detecting sensor 5 is a rear mirror 6 The change in angle may be detected by the stroke sensor. In this case, since the mirror case provided with the stroke sensor is fixed to the vehicle body, the direction of the mirror case indicates the traveling direction of the vehicle body.

[0022]

As described above in detail, according to the present invention, even if the angle of the rear-view mirror adjusted in advance changes due to the load, the tilt sensor detects the tilt of the vehicle body caused by the load, and the optimum position is obtained. Since the angle of the rear-view mirror is automatically adjusted, it is not necessary to adjust the angle of the rear-view mirror each time the luggage is loaded and unloaded.

This eliminates the need for troublesome adjustment work and prevents the vehicle from being driven with the rear-view mirror having a wrong angle, thereby improving safety.
