FIG. 3 is a flowchart showing a left and right rearview mirror selection program, and FIG. 4 is a flowchart showing a reverse interlocking rearview mirror control program. The operation of the embodiment will be described with reference to these flowcharts. The microcomputer 31 starts executing the program shown in FIG. 3 when the left / right selector switch 2 is switched from the neutral position to the right or left. Step S1 after execution starts
In, it is determined whether the left / right mirror switch 3 or the up / down mirror switch 4 has been operated. If either switch is operated, the process proceeds to step S2, and if not, the process proceeds to step S3. In step S2, the drive circuit 35 is controlled according to the operated switch to drive the motor (6, 8, 13, 15) of the selected right or left rearview mirror (5, 12) to adjust the mirror surface angle. Go and return to step S1. On the other hand, when the left / right mirror switch 3 and the up / down mirror switch 4 are not operated, the flag F permitting the reverse interlocking rearview mirror control is set in step S3, and the process proceeds to step S4.

In step S4, it is determined by the door switch 25 whether the open / closed state of the driver's door has changed, that is, whether the driver of the vehicle has been changed. As described above, the reverse interlocking rearview mirror control must always be performed according to the driver's intention, and when the driver is changed, the permission state of the reverse interlocking rearview mirror control is temporarily canceled. If the replaced driver desires reverse interlocking rearview mirror control, the left / right selector switch 2 is once returned to the neutral position, and then switched to the right or left again to repeat the left and right rearview mirror selection operation.

Here, the change in the open / closed state of the driver's door means the change of the driver's door from the closed state to the open state or from the open state to the closed state. Some drivers lean out from the door with the driver's door open to check the rear of the driver's side, and use the outside rearview mirror on the passenger's side to check the rear of the passenger's side. If the reverse interlocking rearview mirror control is canceled when the seat door is opened, it will not be possible to move backward with the driver seat door open.

If it is determined in step S4 that the open / closed state of the driver's door has changed, the process proceeds to step S7, and if not, the process proceeds to step S5. In step S7, the flag F is cleared to cancel the permission of the reverse interlocking rearview mirror control, and the execution of the program ends. On the other hand, when the open / closed state of the driver's door has not changed, step S5
The vehicle speed sensor 24 determines whether the vehicle speed is equal to or higher than a predetermined value. Here, the predetermined value of the vehicle speed is set to, for example, 24 km / h, which is capable of distinguishing between normal forward traveling and reverse traveling. Even if the driver does not change, once the normal forward traveling is performed, the driver may forget that the left / right selector switch 2 remains set to the right or left position. In such a case, when the vehicle is retracted next time, the reverse interlocking rearview mirror control is automatically performed regardless of the driver's intention, which is inconvenient. Therefore, once normal forward traveling is performed, the permission state of the reverse interlocking rearview mirror control is canceled even if the left / right selector switch 2 remains set to the right or left position, and the reverse operation is performed when the vehicle retreats next. When the interlocked rearview mirror control is desired, the left / right selector switch 2 is once returned to the neutral position, and then switched to the right or left again to restart the left / right rearview mirror selection operation.

If it is determined in step S5 that the vehicle speed is 24 km / h or more, the process proceeds to step S7, and if not, the process proceeds to step S6. In step S7, the flag F is cleared to cancel the permission state of the reverse interlocking rearview mirror control, and the execution of the program ends. On the other hand, in step S6, it is determined whether the left / right selector switch 2 has been returned to the neutral position. When the left / right selector switch 2 is returned to the neutral position, the process proceeds to step S7, the flag F is cleared to cancel the permission state of the reverse interlocking rearview mirror control, and the execution of the program ends. If the left / right selector switch 2 remains set to right or left, step S4
Return to and repeat the above process.

When the reverse switch 18 is closed and a backward signal is input, the microcomputer 31 operates as shown in FIG.
The execution of the reverse interlocking rearview mirror control program shown in is started. In step S11 after the start of execution, it is determined whether the flag F is set, that is, whether the reverse interlocking rearview mirror control is permitted. If the flag F is permitted, the reverse interlocking rearview mirror control after step S12 is performed, and the permission is permitted. If not, the program execution ends. In step S12, the sensor 9 detects the current vertical angle of the mirror surface of the right rear-view mirror 5, and the sensor 16 detects the current vertical angle of the mirror surface of the left rear-view mirror 12, which are stored in the microcomputer 31. Store in memory. In a succeeding step S13, the drive circuit 35 is controlled to direct the mirror surfaces of the left and right rearview mirrors 5, 12 downward by a predetermined angle by the motors 8, 15. This tilting angle may be set so that the road surface near the rear wheel is reflected in the center of the mirror. Step S14
In step S15, it is determined whether the reverse switch 18 has been opened, that is, whether the shift lever has been switched to a position other than reverse.
Go to. In step S15, the drive circuit 35 is controlled to return the mirror surfaces of the left and right rearview mirrors 5 and 12 to the original angles stored in the memory by the motors 8 and 15, and the execution of the program ends.

When the left and right rearview mirrors are selected after the shift lever is in the retracted position, the reverse switch 18 is closed first, so that the microcomputer 31 executes the reverse interlocking rearview mirror control program shown in FIG. To start. However, since the permission flag F is not set, the reverse interlocking rearview mirror control is not performed. Next, when the left / right selector switch 2 is switched from the neutral position to the right or left, the microcomputer 31 starts executing the left / right rearview mirror selection program shown in FIG. 3, and when the above-described permission condition is satisfied, the permission flag F is set. To be done. Since the reverse switch 18 is already closed at this time, the microcomputer 31 thereafter executes the control program shown in FIG. 4 again, and performs the reverse interlocking rearview mirror control according to the set permission flag F. That is, even if the left and right rearview mirrors are selected after the shift lever is moved to the retracted position, the above-described reverse interlocking rearview mirror control is consequently performed.

As described above, until the change of the open / closed state of the driver's door is detected or the vehicle speed equal to or higher than the predetermined value is detected after the selection operation of the left and right rearview mirrors is performed,
When the vehicle is moved backward, the reverse-linked rearview mirror control is performed, and once the change in the open / closed state of the driver's seat door is detected or the vehicle speed above a predetermined value is detected, the vehicle is moved backward. Since the reverse linked rearview mirror control is also not performed, the driver does not notice that the left and right rearview mirror selection operations have already been performed, or the normal left and right rearviews are performed after the normal forward running. Even if it is forgotten that the mirror selection operation has already been performed, the occupant's intention is confirmed again, the reverse interlocking rearview mirror control is performed according to the occupant's intention, and operability is improved.

In the above embodiment, the left and right rearview mirrors are directed downward during the reverse interlocking rearview mirror control, but only the passenger side rearview mirrors may be directed downward.

Further, in the above-described embodiment, the operation of the left / right selector switch 2 is set as the condition for the reverse interlocking rearview mirror control. However, a dedicated operation switch for setting the reverse interlocking rearview mirror control is provided, and the operation of the operation switch is performed. May be used as a condition for reverse interlocking rearview mirror control.

Further, in the above-mentioned embodiment, although the reverse operation of the vehicle is detected by the reverse switch for detecting the reverse position of the shift lever, a switch or sensor for detecting the setting of the reverse gear is provided inside the transmission. The reverse operation of the vehicle may be detected.

In the structure of the above embodiment, the left / right changeover switch 2 serves as the operating member, the reverse switch 18 serves as the backward movement detecting means, the door switch 25 serves as the open / close detecting means, and the drive circuit 35 and the motors 8 and 15 serve as the mirror driving means. The microcomputer 31 controls the vehicle speed sensor 2
4 respectively constitute vehicle speed detecting means.

[0025]

As described above, according to the first aspect of the present invention, the reverse setting of the transmission is performed from the selection operation of the left and right rearview mirrors until the change in the open / closed state of the driver's door is detected. Is detected, the mirror surface of the rearview mirror is directed downward, and after the change of the open / closed state of the driver's door is detected after the selection operation of the left and right rearview mirrors, even if the reverse setting of the transmission is detected. Since the mirror surface of the rearview mirror is not turned downward, the occupant's intention is confirmed again and the occupant's intention is confirmed, even if the driver does not notice that the left and right rearview mirrors have already been selected. The reverse interlocking rearview mirror control is performed according to, and operability is improved. According to the second aspect of the present invention, after the selection operation of the left and right rearview mirrors is performed, a change in the open / closed state of the driver's door is detected, or after a vehicle speed equal to or higher than a predetermined value is detected, the gear shift is performed. Even if the reverse setting of the machine is detected, the reverse interlocking rearview mirror control is not performed, so the driver does not notice that the left and right rearview mirror selection operation has already been performed, or once the normal forward movement is performed. Even after forgetting that the left and right rearview mirrors have already been selected after driving, the occupant's intention is confirmed again, and the reverse interlocking rearview mirror control is performed according to the occupant's intention, and operability is improved. improves.
