Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a card-type information storage device in which information data regarding in-vehicle electrical components installed in a vehicle is stored using an IC card having a memory function. be.

(Prior art) In general, in a vehicle, in order to set the driving posture of an occupant to the optimum posture suited to the occupant, for example, the front and back position and tilting position of the seat, the tilting of the mirror, the tilting position of the steering wheel, etc. are adjusted. However, the seat position, mirror tilt, etc. differ depending on each passenger.
It is troublesome to make adjustments every time the occupant changes.

Therefore, conventionally, as disclosed in Japanese Unexamined Patent Publication No. 58-33546, seats and the like have been made electrical components such as electric seats whose position can be adjusted by driving an electric motor, and control data regarding the electrical components has been transferred to the vehicle body. It is known that the electric seat is stored in a memory device, and the position of the electric seat, etc. is automatically adjusted based on the control data stored in the memory device at the same time as riding the vehicle.

However, for example, when many people use the same car,
The control data regarding the electrical components has a wide variety of uses, and it becomes necessary to use a plurality of memory devices. Also, conversely, −
From the perspective of human occupants, the control data must be changed each time the vehicle is different, which is time-consuming.

(Problem to be Solved by the Invention) Therefore, in order to avoid having to store five kinds of control data on the side of the critical body and to eliminate the need to change the control data, the storage capacity is extremely large compared to magnetic cards, etc. Furthermore, it is conceivable to use an IC card that can also incorporate a CPU having an arithmetic processing function, and to store control data regarding electrical equipment such as an electric seat in the IC card.

However, the number of times that IC card data can be updated is approximately 30.
For this reason, each time you turn off the ignition key switch to stop the vehicle's engine, the state of the electrical components at that time is entered into the IC card as the latest control data. If the data is updated, the number of data updates for the IC card will increase to an extent that exceeds the originally permissible number of times, and there is a risk that the IC card will not be able to withstand long-term use.

The present invention has been made in view of these points, and its purpose is to prevent unnecessary data from being updated by updating data on an IC card as described above only under conditions that are practically necessary. To prohibit writing and restrict updating of data, thereby making it possible to use an IC card as a control data storage means for in-vehicle electrical components with good reliability over a long period of time.

(Means for solving the problem) In order to achieve this objective, the solving means of the present invention is as follows:
As shown in the figure, a car is equipped with electric seats, electric mirrors, electric tilt devices, etc. to adjust the driving posture of the occupants! ! Electrical components = 11. , 6.8 Portable IC card 1 having a storage section 12 for storing control data related to
1 is a card type information storage device.

A state detection means 18 for detecting the operating state of the electrical components 4, 6.8 is provided, and the data of the electrical components 4, 6.8 detected by the detection means 18 is stored in the storage section 12 of the IC card 11. A storage content updating means 37 is provided for updating the control data in the storage section 12 by inputting the data into the storage section 12.

Roughly, it detects that the on-vehicle electrical components 4, 6.8 are activated for a purpose other than adjusting the driving posture, such as being activated so as not to disturb the occupants when exiting the vehicle, and at that time, A prohibition means 38 for prohibiting the operation of the storage content updating means 37 is provided.

(Function) With the above configuration, in the present invention, when the IC card 11 held by a passenger makes electrical contact with a device on the vehicle body side, for example, when riding, the control data stored in the storage unit 12 is transferred to the vehicle body side. Based on the read control data, the electrical components 4.6.8 of the vehicle body are operated and controlled, thereby adjusting the driving posture of the occupant to the optimum position.

On the other hand, the operating states of the electrical components 4, 6.8 are detected by the state detection means 18, and for example, when the vehicle engine is stopped in order for the occupant to exit the vehicle, the operating states of the electrical components 4, 6.8 detected by the detection means 18 at that time are The data of 6.8 is input into the storage section 12 of the IC card 11 by the storage content updating means 37, and is replaced with the old data stored until then.
Control data for the IC card 11 is updated.

Further, when the electrical component 4.6.8 is operated for a purpose other than adjusting the driving posture, this is detected by the inhibiting means 38, and the operation of the inhibiting means 38 causes the memory content updating means 37 to be activated. The operation is prohibited, and updating of data in the storage section 12 of the IC card 11 is prohibited. Therefore, only the control data changed by adjusting the driving posture is updated, and unnecessary data unrelated to it is prohibited from being updated, so the number of updates of data to the IC card 11 is reduced accordingly. Therefore, IC card 1
1 can be used for a long period of time.

Control is performed according to the flowchart shown in the figure. That is, first, the controller 13 side waits for the IC card 11 to be inserted into the reader/writer 22 in the first step S1, as shown in FIG. 3(a). Then, the IC card 11 is inserted into the case 23 of the reader/writer 22 to the set position, and the input/output contacts of the IC card 11 are connected to the contacts 35, 35, . When the above determination becomes YES, indicating that the IC card is inserted, the process proceeds to step S2 and the contacts 35, 35 . . . . and an access signal is transmitted to the IC card 11 side via the input/output contacts of the IC card 11 that are in contact with it. This access signal confirms that the contacts 35, 35°, etc. of the reader/writer 22 are in contact with the input/output contacts of the IC card 11, and that the controller 13 and the IC card 11 are securely electrically connected. It is for the purpose of Thereafter, in step S3, it is determined whether or not a response signal from the IC card 11 has been received, and steps Sz and S3 are repeated until the determination becomes YES.

Therefore, in this embodiment, in the above control procedure, when the engine is stopped by receiving the output signal of the position detecting section 18 in step S+a and the ignition key switch 19 is turned OFF, the position detected by the position detecting section 18 is determined. Data on electric seats 4, electric mirrors 6, etc. can be stored on IC card 1.
A storage content updating means 37 is configured to update the old control data stored in the storage unit 12 with new data by inputting the control data into the storage unit 12 of the control unit 12.

Further, in the same step S+s, it is detected that the electric components such as the electric seat 4 and the electric tilt device 8 are operated for a purpose other than adjusting the driving posture, and under that condition, the memory content updating means 37 A prohibiting means 38 is configured to prohibit the operation of the IC card 11, that is, the updating of data in the storage section 12 of the IC card 11.

Next, the operation of the above embodiment will be explained.

When a passenger unlocks the door 2 to enter the car and inserts the IC card 11 into the reader/writer 22 in order to drive the car, the input/output contacts of the IC card 11 are connected to the contacts of the reader/writer 22. 35.35. ... contacts the IC card 11 and the controller 13, and the IC card 11 and the controller 13 are directly electrically connected, and this connection causes the CPU 1 of the controller 13 to
4 and the CPU of the IC card 11 exchange signals,
The control data stored in the storage unit 12 of the IC card 11 is read into the RAM 16 of the controller 13, and each control motor 5 of the electric seat 4, electric mirror 6, and electric tilt device 8 is controlled based on the read control data. 7.10 are operated and controlled via the motor drive unit 17, and the respective positions of the electric seat 4 and the electric mirror 6, as well as the tilt position of the steering wheel 9, are set to the optimum position for the occupant by the operation of each control motor 5, 7.10. is adjusted to

Also, turn off the ignition key switch 19 when exiting the vehicle.
When the engine is stopped by operating F, the input/output contacts of the IC card 11 and the contacts 35, 35. The IC card 11 and the controller 13 are electrically connected by contact with the controller 13, and signals are exchanged between them.
The data regarding the control motors 5, 7, 10 corresponding to the positions of the electric seat 4, electric mirror 6, etc. detected by the position detection unit 18 of the controller 18 is compared with a preset reference range. In that case, when the detected data is within the standard range, it is assumed that the electrical equipment such as the electric seat 4 has been activated to adjust the driving posture of the occupant, and the new detected data is transferred to the IC card. 11 storage unit 12
The old data stored until then is updated with the new data. Therefore, when an occupant changes the optimum position of the electric seat 4 and electric mirror 6 or the optimum tilt position of the steering wheel 9 while driving a car, the changed data is automatically transferred to the I/O.
It can be stored in the C card 11.

On the other hand, electric seats 4 are installed so as not to interfere with passengers exiting the vehicle.
If the position of an electrical component such as a car is changed significantly and its data exceeds the above reference range, the operation of that electrical component is considered to have deviated from the original purpose of adjusting the passenger's driving posture, and the IC Data updating to the storage unit 12 of the card 11 is prohibited, and new data is
1, and the old data stored in the storage unit 12 until then is stored and held as is.

Therefore, updating of unnecessary data unrelated to the adjustment of the driving posture is prohibited in the storage unit 12 of the IC card 11, so the number of times the data is updated becomes extremely small, and the number of times the IC card 11 is updated is the limit. 3000~5
It takes a long time to reach 000 times, and in other words, I
The C card 11 can be used for a long period of time.

The control circuits and movements of the control motors 5, 7 and 10 by the manual switches 39 to 41 described above are constructed in the same manner.
We will explain the control circuit that controls the operation of the electric mirror 6.
Regarding the configuration of the control circuit for the electric tilt device 8, the same parts are given the same reference numerals and the explanation thereof will be omitted.

The first fixed contact 42 is connected to a power source, and is connected to a transistor T via an inverting circuit 45.
When the switch 39 is switched to the first fixed contact 42 side, the output signal of the inverting circuit 45 becomes a Hi-fold signal and the transistor Tr+ is turned on. A relay solenoid 46a of a relay/16 is connected in series to this transistor Tr+, and a relay switch 46b of the relay 46 is connected to one of the above-mentioned seams 1 to 5 to control the rotational position of the motor 5. The connection is made via a changeover switch 47 which is operated accordingly.

On the other hand, the second fixed contact 43 is connected to the first fixed contact 42.
Similarly, it is connected to the power source and to the transistor Tr'z via the inverting circuit 48,
When the switch 39 is switched to the second fixed contact 43 side, the output signal of the inverting circuit/18 becomes H1, and the transistor Tr'2 is turned on. A relay solenoid 49a of a relay 49 is connected in series to transistors 1 to Trz, and a relay switch 49b of the relay 49 is connected to the other connection terminal of the seat control motor 5. or second

By rotating the control motor 5 forward or backward,
The position of the electric seat 4 is manually adjusted.

The output signals of the respective inversion circuits 45 and 48 are input to the CPU 14 via the OR gate circuit 50, and the seat drive manual switch 39 is connected to the first or second
The CPU 14 is configured to detect this when the fixed contacts 42 and 43 are switched.

In general, an output signal from a vehicle speed sensor 51 that detects the traveling speed of the automobile is input to the CPU 14.

In the CPU 14, the processing procedure for writing control data is performed according to the flowchart shown in FIG. Incidentally, since the processing on the IC card 11 side is the same as that in the first embodiment, the explanation thereof will be omitted (see FIG. 4(b)).

First, in the first step Sδ, it is determined whether the vehicle is stopped based on the vehicle speed detected by the vehicle speed sensor 51, and if the vehicle is running, the same step 325 is repeated. When the vehicle is stopped and the determination is YES, the process proceeds to step S26, where it is determined whether each of the manual switches 39 to 41 is turned on;
When this determination is YES due to the ON operation of the manual switches 39 to 41, the F LA
After setting the flag G=1 and storing it in the memory, the process proceeds to step 328, while if the answer is No, the process directly proceeds to step 328. In this step S28, the ignition key switch 19 is turned off. In other words, it is determined whether the on-vehicle engine is stopped, and if the determination is No, the process returns to step S25 and the subsequent steps S, S27. ... is repeated, and when the determination is YES due to the ignition key switch 19 being OFF, the process proceeds to step S29, where it is determined whether the above flag is FLAG=1, and this determination is No, FLAG≠1. The process then proceeds to step S'21, where the IC card 11 is ejected from the reader/writer 22.

Wait for the reception of a response signal from , and repeat steps S'+6°S'17 until a signal is received. If this determination is YES, indicating that the signal has been received, the process proceeds to step S'14, where the current positions of the electric seat 4, electric mirror 6, etc. are detected based on the output signal of the position detection section 18. After this, step S

The end of the write process is determined in step s, and step S'+a is continued until the end of the write process.

Repeat S'+9. When the writing of the control data is completed, a writing completion signal is sent to the IC card 11 in step S'2Q, and then the IC card 11 is sent to the IC card 11 in step S'21.
The card 11 is ejected from the reader/writer 22.

Therefore, in the case of this embodiment, similarly to the first embodiment, the storage content updating means 3 updates the data in the storage section 12 of the IC card 11 in step S'18.
7' is constructed.

Further, in steps Szs to S29, each drive manual switch 39 to 41 is turned ON while the vehicle is stopped,
When the ignition key switch 19 is subsequently turned OFF to stop the engine, it is assumed that the electrical components such as the electric seat 4 were operated for a purpose other than adjusting the driving position, and the memory is stored at that time. A prohibiting means 38' is configured to prohibit the operation of the content processing means 37'.

Therefore, in this second embodiment, based on the idea that the driving posture is not adjusted before turning off the ignition key switch 19 and stopping the operation of the automobile, each of the drive manual switches 39 to 39 is operated while the automobile is stopped.
41, the electric components such as the electric seat 4 are operated and adjusted, and then the ignition key switch 19 is turned OFF.
When the engine is stopped due to the F operation, it is determined that the above-mentioned electrical components were not activated to adjust the driving position, but were controlled so as not to interfere with the passenger's exit from the vehicle, and the IC card 11 Updates to data are prohibited. Therefore, this embodiment can also achieve the same effects as the first embodiment.

(Effects of the Invention) As explained above, according to the present invention, control data regarding in-vehicle electrical components for adjusting the driving posture of an occupant can be transferred to an IC.
When updating the actual control data related to in-vehicle electrical components stored in the card's memory section to the IC card, the data is allowed to be updated only when the electrical component is activated for the purpose of adjusting the driving posture. By doing so, updating of unnecessary data unrelated to adjustment of driving posture is prohibited, so I
The number of times data is updated on the C card is reduced, so the IC card can be used reliably for a long period of time.
