Become.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a functional block diagram of a keyless entry system for a vehicle according to the present invention. In this embodiment, a keyless signal as keyless information is input via a radio wave.

This keyless entry system is mainly composed of a receiving section as a keyless information input section 1, a discriminating section 2 for discriminating a keyless signal received by the receiving section 1, a keyless signal received by the receiving section 1 and discriminated by the discriminating section 2. It comprises a control device 3 for controlling the operation of the door lock system 5 and the power seat system 6 based on signals.

The control device 3 includes a seat position memory 4 as a storage unit, and receives information from a door switch 7 as a door open / close detection unit and an ignition switch 8 as a boarding detection unit.

The receiving unit 1 receives a keyless signal from a transmitter possessed by the driver and outputs it to the determining unit 2. Here, in the present embodiment, the keyless entry is possible by the two transmitters A and B 10A and 10B, and the two transmitters 10A and 10B of the A and B transmit different keyless signals respectively. Things.

The discriminating unit 2 determines that the keyless signal received by the receiving unit 1 is A, B
It discriminates which signal, and outputs the decision result 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 a signal input from the determination unit 2.

The door lock system 5 includes a door lock controller 51
Lock actuator 52 of each door via the servo mechanism
Are driven to lock or unlock the door, and are locked or unlocked by operation of the switch 53 or a signal from the control device 3.

The power seat system 6 is configured such that the position of the seat in the front-rear or up-down direction and the angle of the backrest can be driven by motors 62 serving as actuators.
Each of the motors 62... Is driven through 61 to set an arbitrary seat position.

The door switch 7 outputs a signal to the control device 3 when detecting that the driver's seat side door is opened, 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 the position information of the seat detected by the sensors 41 provided in the seat (power seat system 6). By driving the power seat system 6 based on the stored information, The stored seat position can be reproduced (reproduced). The seat position memory 4 has a capacity capable of storing at least the number of seat positions (the number of keyless signals) of the transmitters 10A and 10B, and corresponds to each of A and B two different keyless signals. To memorize the seat position. The storage of the seat position is performed by operating the switches 4A and 4B.

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

As described above, the control device 3 activates the door lock system 5 according to the signal input from the determination unit 2 to release the door lock, and also activates the power seat system 6 to respond to the input signals (A, B). The operation is controlled so as to reproduce the seat position stored in the seat position memory 4 in advance, but if a signal is input from the door switch 7 during the reproduction of the seat position, the reproduction of the seat position is temporarily interrupted, and then the ignition switch 8 Restarts when a signal is input from.

That is, as shown in the flowchart of FIG. 2, when a keyless signal is input to the receiving section 1 (S1), the discriminating section 2 judges whether the keyless signal is A or B (S2). The reproduction of the seat position corresponding to the keyless signal determined by the step 2 is started (S3). When a signal is input from the door switch 7 during this seat position reproduction (door opening is detected) (S4), the reproduction of the seat position is interrupted (S5). Thereafter, when a signal is input from the ignition switch 8, the seat position reproduction is restarted (S6).

In other words, the driver recognizes that the driver is in the riding state by opening the door, stops the movement of the seat (reproduction of the seat position) during this riding, secures riding comfort, and terminates the riding by turning on the ignition switch 8. It is determined that the reproduction of the seat position is resumed 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, a signal that has been reproduced without a signal input from the door switch 7 during the reproduction of the seat position is shown. The case (1) indicates that the reproduction is interrupted by the signal input from the door switch 7 during the reproduction of the seat position, and the reproduction is resumed by the signal input of the ignition switch 8 to complete the reproduction.

In the above embodiment, the door switch 7 is applied as the door opening / closing detecting means, and the ignition switch 8 is applied as the boarding detecting means. However, the present invention is not limited to this, and it can be changed as appropriate. It is. For example, the door opening / closing detecting means may detect that a hand touches a door lever, and the occupant detecting means may be configured by closing a door or providing a switch on a seat. .

[Effects of the Invention] According to the keyless entry system for a vehicle according to the present invention as described above, even when the seat position is reproduced by a keyless signal, the seat stops when the user gets on the vehicle, so that the rideability can be secured. In other words, by setting the seat position in advance in association with the keyless signal, the seat position is reproduced together with the unlocking of the door, and the reproduction of the seat position does not hinder the ride, which is extremely convenient. is there.
