DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an automatic adjusting device for a vehicle seat.

[0002]

2. Description of the Related Art Conventionally, as an automatic seat adjusting device for a vehicle, for example, as disclosed in Japanese Patent Application Laid-Open No. 61-205523, an automatic seat adjusting device for storing and reproducing a desired seat condition of a driver, A keyless entry device that unlocks the door lock device without a key from outside the vehicle is provided, and when the driver operates the keyless entry device when getting into the vehicle by linking the two devices, the door lock is released. By automatically unlocking and inputting the entry signal to the automatic seat adjustment device, the driver's seat is automatically adjusted to the desired seat state before entering the vehicle,
There has been known one that facilitates sitting in a driver's seat.

[0003]

However, in the above-described conventional apparatus, the driver's seat may be inadvertently activated after sitting on the driver's seat. For example, in an automatic seat adjusting device that stores and reproduces a plurality of desired seat states, and selects and reproduces a desired seat state corresponding to the received keyless entry signal according to the type of the received keyless entry signal, After sitting in the desired seat state, if another person operates the keyless entry device to get on,
The driver's seat moves to the seat state according to the entry signal. Even when the plurality of desired seat states are not stored in this way, even when another person uses the keyless entry device when the user rides without using the keyless entry device and sits in the driver's seat, the driver's seat remains in the driver's seat. It works independently of the intention of the person. In such a case, the driver may feel uncomfortable or uncomfortable.

[0004] The present invention has been made in view of such a point, and an object of the present invention is to allow a driver to sit down when the automatic seat adjustment device is operated in conjunction with the operation of the keyless entry device as described above. The rest is to prevent inadvertent operation of the driver's seat that does not depend on the driver.

[0005]

In order to achieve the above object, according to the present invention, the interlocking of the automatic seat adjusting device is permitted or prohibited depending on whether or not the driver's seat is seated.

Specifically, as shown in FIG. 1, the specific solution of the present invention is to provide an automatic seat adjusting means 6 for storing and reproducing a desired seat state of a driver and a door lock device from outside the vehicle without a key. A vehicle seat automatic adjusting device comprising keyless entry means 8 for locking and control means 16 for controlling the automatic seat adjusting means 6 based on the operation of the keyless entry means 8 to adjust the driver's seat to a desired seat state. Is assumed. The seat detection means 12 detects the presence or absence of the driver's seat. The keyless entry means 8 detects the presence of the driver's seat detected by the seat detection means 12.
And a prohibiting means 17 for prohibiting a new automatic adjustment of the driver's seat by the control means 16 based on the new operation.

[0007]

With the above arrangement, according to the present invention, while the driver is seated in the driver's seat, even if the keyless entry means 8 is newly operated, the control means 16 automatically controls the seat based on the keyless entry signal. An attempt is made to control the adjusting means 6, but this control is prohibited by the prohibiting means 17 and new automatic adjustment of the driver's seat is prevented, so that the driver's seat does not change to another seat state.

[0008]

As described above, according to the vehicle seat automatic adjustment device of the present invention, even if the keyless entry device is newly operated while the occupant is seated in the driver's seat, the operation of the automatic adjustment device is not affected. Control of the driver's seat to a desired seat state based on the prohibition of the driver's seat based on the intention of the person sitting in the driver's seat is prevented. Pleasure can be eliminated.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 2 shows the overall schematic structure of the present invention, wherein 1 is a motor for adjusting the front / rear position or height position of the driver's seat, 2 and 3 are a pair of relay devices for rotating the motor 1 forward and backward, Reference numeral 4 denotes a position sensor for detecting the rotation angle of the motor 1, that is, the front / rear or height position of the driver's seat.

Reference numeral 5 denotes a control unit having a CPU and the like therein. The unit 5 stores therein a plurality of desired seat states of a driver's seat in advance, and issues a command for position adjustment of the driver's seat. Sometimes the position sensor 4
Has a function of controlling the operation of the motor 1 in the normal rotation or the reverse rotation by using the pair of relay devices 2 and 3 based on the signal, and controlling the driver's seat to the desired seat state. The devices 1 to 5 constitute an automatic seat adjusting means 6.

Reference numeral 8 denotes keyless entry means. The entry means 8 includes a transmitter 9 held and operated by an occupant, and a receiver 10 for receiving an output signal of the transmitter 9.
And an actuator (not shown) for unlocking or locking (door locking) the door lock in response to a door unlocking signal or a door locking signal output from the receiver 10.

Further, reference numeral 12 denotes a seating detection switch as seating detection means for detecting the presence or absence of an occupant in the driver's seat.
3 is a door open detection switch for detecting the open state of the vehicle door, 14 is a door close detection switch for detecting the closed state of the door of the vehicle, and 15 is disposed around the driver's seat to determine the front / rear or height position of the driver's seat. These are position adjustment switches for manual adjustment, and the states of these switches 12 to 15 are input to the control unit 5. Further, a door unlock signal (keyless entry signal) of the receiver 10 of the keyless entry means 8 is also input to the control unit 5.

Next, the automatic adjustment of the driver's seat by the control unit 5 will be described with reference to the control flow of FIG. Starting, in step S1, it is determined whether or not the keyless entry operation of the keyless entry means 8 by the transmitter 9 has been performed based on the presence / absence of a predetermined door unlock signal from the receiver 10, and if the keyless entry operation has been performed. In step S2, it is determined whether or not the occupant is seated in the driver's seat based on the output signal of the seating detection switch 12.
Since the driver is not seated at first, it is determined in step S3 whether or not the driver's seat is at a set position of a desired seat state corresponding to the type of the received door unlocking signal. Therefore, in step S4, the relay devices 2, 3
, The motor 1 is controlled to rotate forward or reverse to start moving the driver's seat. Then, in step S5, it is determined whether or not the door has been opened. If the door has been opened, it means that the driver has stepped in, and the position adjustment of the driver's seat is temporarily stopped in step S6. Then, in step S7, it is determined whether or not the door is closed. If the door is kept open, the position adjustment is temporarily stopped. If the door is closed, the process returns to step S4 to return to the driver's seat. Is resumed, and if the driver's seat reaches the set position in step S3, the position adjustment of the driver's seat is ended in step S8.

On the other hand, if it is determined in step S1 that the transmitter 9 has not been operated and the keyless entry means 8 has not been operated, it is determined in step S9 whether or not the manual switch 15 for adjusting the position of the driver's seat has been operated. If there is no operation, the process immediately returns without adjusting the position of the driver's seat in step S8. However, if there is a manual operation, the motor 1 is appropriately driven according to the manual operation in step S10 to adjust the position of the driver's seat. I do.

Then, for example, when another occupant operates the transmitter 9 to newly activate the keyless entry means 8, the determination in step S1 becomes YES, but the seating is detected in step S2. Since the switch 12 detects the seating of the driver's seat, the process proceeds to step S8 unless the manual switch 15 for adjusting the position of the driver's seat is manually operated in step S9, and the process returns without performing the position adjustment of the driver's seat.

Therefore, in the control flow of FIG.
By the steps S1 to S8, the keyless entry means 8
The control means 16 controls the automatic seat adjusting means 6 based on the operation of the control means and adjusts the driver's seat to a desired seat state with the door closed. In addition, by the steps S2 and S8 of the control flow, the seating detection switch 1
Prohibiting means 17 for prohibiting a new automatic adjustment of the driver's seat by the control means 16 based on a new operation of the keyless entry means 8 while the driver's seat detected by step 2 is seated.
Is composed.

Therefore, in the above embodiment, FIG.
When the driver operates the transmitter 9 to operate the keyless entry means 8 at the point a, the motor 1 is driven to rotate in conjunction therewith, and the position adjustment of the driver's seat is started. This position adjustment is temporarily stopped when the door in which the driver gets in is open, but is resumed when the door is closed and the occupant sits in the driver's seat.
The drive control of the motor 1 is stopped at the point where the process is completed.

Now, when the occupant is seated in the driver's seat as described above, as shown by point c in FIG. 4, another person newly operates the transmitter 9 to activate the keyless entry means 8. If you do, the driver's seat is already occupied,
For this reason, the prohibiting means 17 is actuated, and the drive control of the motor 1 is prohibited and the position of the driver's seat is not adjusted. No discomfort or discomfort.
