Abstract

PURPOSE:To secure boardability by controlling the regenerative movement of a seat so as to suspend it till 'boarding' is detected at a time when a door open state is detected during seat movement regeneration, and solving such a problem that people must wait their boarding until completion of the regeneration of a seat position. CONSTITUTION:A receiving part 1 receives each keyless signal out of transmitters 19A, 10B a driver has, outputting these signal to a discriminating part 2 which discriminates the keyless signal to be which signal of these transmitters 10A, 10B, outputting the discriminated result. A controller 3 controls each operation of a door lock system 5 and a power seat system 6 by means of a signal input out of the discriminating part 2. In this case, seat position regeneration is once suspended when a signal is inputted out of a door switch 7 during this seat position regeneration, then it is resumed when a signal is inputted from an ignition switch 8. According to this method, even in the seat position regeneration, when opening the door and boarding a car, a seat regenerative movement is suspended and thereby boardability is securable while after boarding, the seat regenerative movement is resumed and it is regenerable in a correct position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyless entry system for a vehicle that locks or unlocks a vehicle by inputting keyless information without using a key.

[Prior art and its problems] Recently, some vehicles are equipped with a so-called keyless entry system that allows doors to be locked or unlocked without using a key.

A keyless entry system operates a door lock system by inputting keyless information such as an electric signal or a code number, and is extremely convenient as it can be locked or unlocked without a key. be.

On the other hand, the position of the seat 1~ in the longitudinal or vertical direction and the angle of the backrest can be driven by an actuator such as a motor, and a storage means is provided for storing position information of the stiffness, and the information is stored in the storage means by operating a switch. There is a reproducible auto seat position device in the seat position. (Refer to Japanese Unexamined Patent Publication No. 63-305046, etc.) According to such an automatic seat position device, the seat positions of a plurality of drivers who drive the vehicle are stored in the storage means, so that switch operation can be performed easily. This is extremely convenient, as it allows the driver to instantly adjust the seat position to suit the driver.

Here, it is conceivable to operate an automatic seat position device based on keyless information in the above-mentioned keyless entry system. In other words, a plurality of different pieces of keyless information are prepared, and each piece of keyless information is stored in correspondence with the seat position of the driver who uses it.
It is stored in the first stage, and when keyless information is input, the door is unlocked and the seat is moved to the seat position corresponding to the keyless information (regenerates the seat position of the driver to use). .

However, when configured in this way, the sequence of operations of opening the door and getting into the vehicle after unlocking the door is usually continuous for a short period of time, and when getting into the vehicle, the seat position is still being regenerated (the seat is There was something that could have happened since the train was in transit). It is extremely difficult to get into the vehicle when the seat is moving, and as a result, the problem arises that you have to wait until the seat position has been regenerated before you can get in the vehicle.

[Object of the Invention] In view of the above-mentioned circumstances, the present invention provides a keyless entry system for a vehicle that can stop the seat when getting into the vehicle to ensure ease of riding even when the seat position is regenerated using keyless information. ,With the goal.

[Configuration of the Invention] Therefore, the keyless entry system for a vehicle according to the present invention includes a keyless information input section, a discriminating section that discriminates the keyless information input to the keyless information input section, and a keyless entry system for a vehicle according to the present invention. It is equipped with a power seat system that can move and drive the seat, a door opening/closing detection means for detecting door opening/closing, a seven-stage occupancy detection device for detecting entry, and a memory means for memorizing the seat position. Based on the keyless information inputted to the keyless information input section and determined by the discriminating section, the door lock system is operated and unlocked, and power is supplied to reproduce the seat position corresponding to the keyless information stored in the storage means. and a control device that controls and drives the seat system, and when the door opening/closing detection means detects whether the door is open during seat movement reproduction, the riding detection means detects whether the seat is boarded. The system is configured to control the playback movement of the sheet to be interrupted until the time when the playback movement of the sheet is interrupted.

According to this, even when the seat position is being regenerated, when riding with the seat open, the seat regeneration movement is interrupted to ensure riding comfort, and after the first ride, the seat regeneration movement is resumed to the correct position. It will be played.

[Embodiments of the invention] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a functional block diagram of a vehicle keyless entry system according to the present invention. In this embodiment, a keyless signal as keyless information is manually generated via radio waves.

This keyless entry system mainly consists of a receiving section 1 as a keyless information input section, a discriminating section 2 for discriminating a keyless signal received by the receiving section, a discriminating section 2 for receiving a keyless signal, and a discriminating section 2 for receiving the keyless signal. It is comprised of a control device 3 that controls the operation of a door lock system 5 and a power seat system 6 based on the following.

The control device 3 includes a seat position memory 4 as a storage means, and receives information from a door switch 7 as a door opening/closing detection means and an ignition switch 8 as an entry detection means.

It is becoming more and more powerful.

The receiving unit 1 receives a keyless signal from a transmitter carried by the driver and outputs it to the 1 determining unit 2. In this embodiment, two transmitters 110A and 13, keyless entry is provided by IOB, and two transmitters 10A, A and B.

10B are designed to transmit different keyless signals.

The determining unit 2 determines whether the receiving unit 1 or the received keyless signal is A or B.
It determines which signal it is and outputs the result of the determination to the control device 3.

The control device 3 controls the operation of the door lock system 5 and the power seat system 6 based on the signal input from the discrimination section 2.

The door lock system 5 is a Torrotsuta controller 51.
or lock actuator 5 for each door via servo mechanism
2... are driven to lock or unlock the door, and the door is locked or unlocked by operating the switch 53 or by a signal from the control device 3.

The power seat system 6 is configured such that the position of the seat in the longitudinal and vertical directions and the angle of the backrest can be driven by a motor 62, which is an actuator.
An arbitrary seat position can be set by driving each motor 62 through a power seat controller 61 by operating a switch (not shown).

When the door switch 7 detects that the door of the driver's seat is opened, it outputs a signal to the control device 3, and the ignition switch 8 outputs a signal to the control device 3 by energizing the ignition device of the engine.

The seat position memory 4 stores seat position information detected by sensors 41 provided in the seat (power seat system 6), and drives the power seat system 6 based on this stored information. This allows the stored seat position to be reproduced (reproduced). Further, this seat position memory 4 is at least connected to the transmitter 10A.

It has a capacity that can store 10B seat positions (the number of keyless signals), and can store seat positions corresponding to each of three different keyless signals, A and B. . This seat position is memorized using switch 4A.

This is done by operating 4B.

Next, the operation control of the door lock system 5 and the power seat system 6 by the control device 3 will be explained.

As described above, the control device 3 operates the door lock system 5 to unlock the door based on the signal input from the discrimination section 2, and also operates the power seat system 6.
The operation is controlled to regenerate the seat position previously stored in the seat position memory 4 in response to the λ force signals (A, B), or the seat position is changed when a signal is input from the door switch 7 while the seat position is being regenerated. The reproduction is temporarily interrupted and then resumed when a signal is input from the ignition switch 8.

That is, as shown in the flowchart of FIG. 2, when a keyless signal is input to the receiving unit 1 (≦1), the determining unit 2 determines whether the keyless signal is A or B (S2). Seat position reproduction corresponding to the keyless signal determined in step 2 is started (S3). If a signal is input from the door switch 7 during this seat position regeneration (it is detected that the door is open) (S4), the seat position regeneration is interrupted (S5). Thereafter, when a signal is input from the ignition switch 8, the seat position regeneration is resumed (S6).

In other words, when the door is opened, it is recognized that the driver is in the vehicle, and at this occupancy rate, seat movement (seat position regeneration) is stopped to ensure drivability, and the ignition switch 8 is energized to ensure that the driver is in the vehicle. When it is determined that the regeneration has ended, the regeneration of the seat position is restarted and completed.

A time chart of this operation is shown in Fig. 3, and in the case of a keyless signal indicated by A in the figure, there is no signal input from the door switch 7 during the playback of the seat position, and the regeneration is completed, and it is indicated by B in the figure. In the case of a keyless signal, reproduction is interrupted by a signal input from the door switch 7 during seat position reproduction, and reproduction is resumed and completed by a signal input from the ignition switch 8.

In the above embodiment, the door switch 7 is used as the door opening/closing detection means, and the ignition switch 8 is used as the boarding detection means, but the present invention is not limited to these and may be changed as appropriate. Of course. for example,
The door opening/closing detection means may detect that a hand touches the door lever, and the riding detection means may detect that the door is closed or a switch may be provided on the seat.

[Effects of the Invention] As described above, according to the keyless entry system for a vehicle according to the present invention, even if the seat position is regenerated by a keyless signal, the seat can be stopped when getting into the vehicle to ensure ease of riding. . In other words, by setting the seat position in advance in correspondence with the keyless signal, the seat position will be regenerated when the door is unlocked.
However, this regeneration of the seat position does not interfere with riding and is extremely convenient.
