Description

[Detailed description of the invention] [Industrial application field]

This invention uses a controller switch inside the vehicle to
The present invention relates to a remote control fender mirror configured to remotely adjust the angle of the mirror body of the fender mirror.

[Conventional technology]

With this type of remote control fender mirror,
The angle of the mirror body, which is driven downwards by a driving means such as an electric motor built into the fender mirror case, can be adjusted using a controller switch installed in the driver's seat, etc. When reversing the car into a garage or parking it on the roadside, it is especially difficult to check the position of the rear wheels on the opposite side of the driver's seat, and there is sometimes a risk of the wheels falling off or colliding with each other.Remote control type In cars equipped with fender mirrors, it is possible to operate the mirror body while remaining inside the car so that the position of the rear wheels at the rear of the side of the car can be seen, but it is still difficult for inexperienced people to operate the mirror body. It is very important to operate the mirror body 1.
When backing up, you have to turn the controller switch on. Also, the next time you drive normally, The mirror body, which has been turned downward so that the wheels can be seen, must be returned to its original normal state. Japanese Utility Model Application No. 58 56646 discloses a side mirror equipped with a side mirror that allows people to see through the mirror when a person is involved, but even with this, the rear wheel part cannot be seen. In order to do this, the driver must adjust the position of the mirror body one by one.

[Problem to be solved by the invention]

This invention was devised under the above circumstances, and the problem to be solved is to improve the vehicle body. When the driver attempts to move, the mirror body automatically assumes a preset reverse position, that is, a position where the rear wheels can be seen, without the driver having to operate the mirror body. Under normal conditions, the mirror body is automatically set to a preset normal position, making it safer to back into a garage or drive a car on the roadside. .

[Means to solve the problem]

In order to solve the above problems, the remote control type fender mirror of the present invention includes the following means. a mirror body, a drive means for tilting the mirror body vertically and horizontally, a position sensor for detecting the tilted position of the mirror body; a first storage means for storing the normal position of the mirror body detected by the position sensor; a second storage means for storing the position of the mirror body during reversing detected by the position sensor; a reversing detection means for generating a reversing signal when the vehicle is running in reverse; a normal state; control means for controlling the driving means so that the mirror takes the position stored in the second storage means; and the mirror takes the position stored in the second storage means in response to a backing signal from the backing detection means. As a drive means for tilting the mirror body downward and left and right, a known electric drive means such as a one-motor or two-motor type is used. For the position sensor 1, the tip of the axially moving detection body is brought into contact with the rear retracted part of the mirror body. It is possible to choose to use a potentiometer or a wire-wound potentiometer whose output varies depending on the number of rotations of the motor. The first and second storage means are
ROM or non-volatile RAM is used. The reverse detection means can be realized by a switch that is turned on when the shift lever of the transmission is put into reverse. Furthermore, the control means is realized by a microcomputer.

[Effect]

Normally, the control means controls the drive means for the mirror body so that the mirror body assumes a position previously stored in the first storage means. This first storage means stores data obtained by digitizing signals from the position sensor. The control means compares the signal from the position sensor indicating the current position of the mirror with the data read from the first storage means, determines how to move the drive means, and moves the drive means according to this determination. control. When the mirror body is moved, a change in its position is fed back via the position sensor, and the drive means is controlled until the fed back signal matches the data read from the first storage means. On the other hand, when a signal indicating that the vehicle body is in the reverse state is input from the reverse detection means, the control means compares the signal from the position sensor indicating the current mirror position with the data read from the second storage means. Then, it decides how to move the drive means and controls the drive means according to this decision. When the mirror is moved, a change in its position is fed back via the position sensor, and the driving means is controlled until the fed-back signal matches the data retrieved from the second storage means.

【effect】

In the remote control second rear rear mirror of the present invention,
When backing up a heavy object, the mirror body automatically allows the driver to visually see the rear wheels from the driver's seat without the driver having to operate the control lever.
The 4Cs ensure that driving into a garage or parking on the roadside is as safe and secure as possible.

In the figure, reference numeral 20 is a vehicle speed sensor, 21 is a Hanoksu inch as a back detecting means, and 22 is a position sensor 14, 15.
The position signal from Section II! is used as the normal position indicating the normal position of the mirror. A normal position memory switch 24 is used to store the position signals in the means 23, and a back position memory switch 24 stores the position signals from the position sensors 14 and 15 in the second storage means 25 as a back signal indicating the rearward position of the mirror. It is. Note that the above-mentioned 19th means 23 and 2nd i, O means 25 are made of non-volatile R so that their contents will not be erased even if the ignition switch is turned off.

Step 106) Return to step 101. If the left mirror controller 17 is off, it is determined in step 107 whether the right mirror controller 18 is on, and if it is on, the drive means 7 is controlled according to the command from the second controller 18. Now, adjust the mirror body 9 to the position desired by the operator (step 108), and return to step 101). If the right mirror controller 18 is off, the process advances to step 109. That is, steps 105 to 108
is a step in which the operator remotely controls the mirror body 8.9 according to the left and right controllers 17.18. In step 109, it is determined whether the back switch 21 is on or not. If it is on, the drive means 6.7 moves the mirror body 8.9 to the position indicated by the position data read from the second storage means 25 (i/ , "Fl, i.e. -5, is adjusted and controlled to take the expected position when reversing. More specifically, the control means CP tJ 25 uses the current mirror input from the position sensor 14.+5. Position signal and 1

The control by 25 is such that the signal from the position sensor 14-15, which is sequentially fed back as the mirror body 8.9 moves, is equal to the back 4I'I position data read out from the second storage means 25 in 1-. I can keep going until I get it. In addition, if interrupt permission is granted in step 111 and the signal from the vehicle speed sensor 20 indicates that the speed is 15 km/h, for example, the mirror body 8.9, which was in the reverse position, is changed to the normal position. Adjustment control is performed to adjust the amount of force (step 112). This control is also controlled by CP [
J25 is carried out in the same manner as step 110 in -1-. If the back switch 21 is off in step +09, the process returns to step +01. In addition, in this flowchart, the condition for returning the mirror after reversing is that the vehicle speed must exceed a certain speed.
However, for example, the condition may be that the back switch 21 is off. The remote control type fender mirror of the embodiment shown in FIG. 2 is used in the following manner. First, operate the left mirror controller 7 and the controller 18 for the left and right mirrors 8.9.

The drive means 6.7 each include one motor 6a. 7a and electromagnetic solenoids 6b and 7b. The table on the left in FIGS. 5a and 5b shows the direction of movement of the mirror body 8.9 and the connections and connections between the respective terminals in the switch group 30. For example, the left mirror body 6 is If it does not move in either direction, it indicates that terminal B is electrically connected to terminal 1, and terminal E is electrically electrically connected to terminal M2 and terminal SL. The switch circuit 27 of the present invention is shown in FIGS. 5a and 5b.
The relationship equivalent to the conduction relationship between the terminals in the table on the left side of the figure is expressed by the six transistors Tri to Trfi and the relays Rel to Re1 controlled by the microcomputer 3.
It is composed of a combination of O. The table on the right side of FIGS. 5a and 5b shows how the transistors Tr1 to Tr6 should be controlled when the mirror body 8.9 does not move horizontally or downwardly by -L. For example, when moving the left mirror body 8 in the L direction, it is understood that the l transistors Tr2, Tr3, and Tr6 should be turned on. When the transistor is in this state, the result is the same as if the terminal B was electrically connected to the terminal m1 and the terminal E was electrically electrically connected to the terminal M2 and the terminal St. To move the left mirror body 8 downward, use Tri,
Tr4 and Tr6 may be turned on. Karini,
When it is determined that the back 4ib should not move, the CPU 26 automatically controls the above Trl and Tr4 until the signal from the position sensor 14 matches the data read out from the second storage means 25.
And the Hass voltage is applied to Tr6. In addition,
The operation and usage of this example are essentially the same as those of the first example, so a description thereof will be omitted. As explained above, in the remote control type fender mirror of the present invention, the mirror body automatically assumes a position that facilitates reversing operation when reversing, and automatically returns to the normal state during normal driving. Alternatively, it becomes easier and safer to drive a vehicle on the roadside. Note that the scope of the present invention is of course not limited to the above-described embodiments. For example, in the embodiment, the driver is able to set the normal position and reverse position that suit him/her by the first and second storage means consisting of a normal position memory switch, a reverse position memory switch, and a non-volatile RAM. , one or both of the normal position and the back position may be stored in the ROM in advance. In this case, the normal position memory switch and/or the back position memory switch are not required.
