Description

Description: TECHNICAL FIELD The present invention relates to a card-type information storage device configured to store information data regarding in-vehicle electrical components mounted on a vehicle by an IC card having a memory function. Is.

(Prior Art) Generally, in a vehicle, in order to set an occupant's driving posture to an optimal posture suitable for the occupant, for example, a seat front-rear position, a tilt position, a mirror tilt, a steering wheel tilt position, etc. are adjusted. However, the seat position, the tilt of the mirror, and the like differ depending on each occupant, and it is troublesome to perform the adjustment each time the occupant changes.

Therefore, conventionally, for example, as disclosed in Japanese Patent Laid-Open No. 58-33546, a seat or the like is an electric component such as an electric seat whose position can be adjusted by driving an electric motor, and control data relating to the electric component is stored on the vehicle body side. There is known a memory device in which the position and the like of the electric seat are automatically adjusted on the basis of the control data stored in the memory device at the same time as getting on the vehicle.

However, for example, when a large number of people use the same car, the control data regarding the above electrical components are various and various,
The need to use multiple memory devices arises. Conversely, from the perspective of one occupant, when the vehicle is different,
Control data must be changed each time, which is troublesome.

(Problems to be solved by the invention) Therefore, in order to avoid storing such a large amount of control data on the vehicle body side and to eliminate the change operation of the control data, the storage capacity is extremely large as compared with a magnetic card and the like. It is conceivable to use an IC card that can also include a CPU having a calculation processing function and store control data relating to electric components such as an electric seat.

However, the allowable number of data updates for IC cards is about 3000.
It is guaranteed only about 5,000 times, so every time the ignition key switch is turned off and the vehicle engine is stopped, the state of electrical components is input to the IC card as the latest control data at that time and that data is updated. If this is done, the number of times the data for the IC card is updated exceeds the originally allowed number of times, and there is a risk that it will not be able to withstand long-term use.

The present invention has been made in view of such points, and an object thereof is to limit the update of data by performing the update of data for the IC card as described above only under predetermined conditions. Therefore, it is to make it possible to reliably use the IC card as the control data storage means for the on-vehicle electrical equipment for a long period of time.

(Means for Solving Problems) In order to achieve this object, the solution means of the present invention adjusts a driving posture of an occupant such as an electric seat, an electric mirror, an electric tilt device, etc., as shown in FIG. In order to achieve this, a card-type information storage device provided with a portable IC card 11 having a storage unit 12 that stores control data relating to vehicle-mounted electric components 4, 6, 8 mounted on the vehicle body is premised.

Then, the operating state detecting means 37 for detecting the operating state of the engine mounted on the vehicle, and the position detecting means 18 for detecting the operating position of the electrical components 4, 6, 8 are provided, and both the detecting means 18, Upon receiving the output signal of 37, when the engine is stopped, the data of the electrical components 4, 6 and 8 detected by the position detecting means 18 are input to the storage section 12 of the IC card 11 and the control data of the storage section 12 is updated. A storage content updating means 38 is provided.

Further, the control data detected by the position detecting means 18 is compared with the control data stored in the storage section 12 of the IC card 11, and the prohibition of prohibiting the operation of the stored content updating means 38 when the both data are the same. The means 39 is provided.

(Operation) With the above configuration, in the present invention, when the IC card 11 carried by the occupant makes electrical contact with a device on the vehicle body side, for example, the control data stored in the storage unit 12 is transferred to the vehicle body side. Electrical components of the car body that are read and based on the control data
4,6,8 are actuated and controlled, whereby the driving posture of the occupant is adjusted to the optimum position.

In addition, the operating state of the vehicle-mounted engine is determined by the operating state detecting means 37.
In addition, the operating positions of the electrical components 4, 6 and 8 are respectively detected by the position detecting means 18, and when the occupant stops the vehicle-mounted engine in order to get off the vehicle, the electrical components detected by the position detecting means 18 at that time point. The data of 4, 6 and 8 are input to the storage unit 12 of the IC card 11 by the storage content updating means 38 and exchanged with the old data stored until then, and the IC card
The control data for 11 is updated.

At that time, prior to updating the control data, the control data detected by the position detecting means 18 is compared with the old data stored in the storage section 12 of the IC card 11, and if both data are the same, the prohibition is prohibited. The operation of the storage content updating means 38 is prohibited by the means 39, and the storage section of the IC card 11 is
Data updates to 12 are suspended. For this reason,
Only the control data changed by resetting the driving posture is updated, and unnecessary data update is prohibited.Therefore, the number of data updates to the IC card 11 is reduced, and the IC card 11 It can be used for a long period of time.

Data update to the storage unit 12 of the card 11 is prohibited, new data P _NEW is not written in the storage unit 12 of the IC card 11, and the old data P _NEW stored in the storage unit 12 is stored.
_OLD is stored and retained as it is.

Therefore, in this case, since unnecessary updating of the data in the storage unit 12 of the IC card 11 is prohibited, the number of times of updating the data becomes extremely small, and the number of updates of the IC card 11 reaches 3000 to 5000 times. It takes a long time to reach it, in other words, the IC card 11 can be used for a long time.

(Effects of the Invention) As described above, according to the present invention, the control data relating to the on-vehicle electrical components for adjusting the driving posture of the occupant is transmitted to the IC.
Stored in the memory of the card,
When updating the actual control data for in-vehicle electrical components to the IC card, by allowing the data update only when the new data is different from the old data, unnecessary data updates are prohibited. As a result, the number of times data is updated to the IC card is reduced, so that the IC card can be used reliably for a long time.
