Description

[Detailed description of the invention] Technical field of the invention This invention relates to a control device for an electric car seat that has a function of storing and reproducing the seat position, and in particular prohibits anyone other than the owner from storing the seat position on the owner key. It concerns the improvement of means.

Prior Art and Problems Conventional devices of this type employ the following two storage operation procedures. First, if you want to memorize a certain seat position, use the manual switch to move the seat to the seat position you want to memorize.
While pressing the pattern select switch memory key in the console box, press the pattern select switch keys you want to memorize ([1], [2], [3],
[Owner]) until the buzzer ends, the current seat position is stored in the corresponding key (simultaneous press memory operation method). Then, within 5 seconds after releasing the memorization key, press the key you want to memorize until the buzzer stops sounding, and the current seat position will be memorized in the corresponding switch (separate press memorization method).

By the way, since the owner key in the pattern select switch is assigned exclusively to the owner, it would be a problem if another person were to use this key and store a different seat position. Therefore, in conventional control devices of this type, if you want to prohibit new storage after the storage of the owner key is completed, turn on the secret switch located under the seat.
Even if you tried to store data using the above storage method, the buzzer would not sound even if you pressed the owner key, and a function (secret function) was added that prohibited the storage operation. Of course, at this time, it is possible to store data in other keys [1] to [3].

However, since a secret switch is required in terms of hardware, the number of parts increases, which increases costs and causes of failures.

Purpose and structure of the invention This invention aims to solve these conventional problems, and the gist of this invention is to create an electric Front and rear of type car seats,
Control of an electric vehicle seat that stores a position in a vertical direction, reads corresponding position information from a position storage means when an owner key and other keys are pressed, and positions the electric vehicle seat at that position. In the apparatus, a first detection means detects that the owner key and the storage key are operated in a predetermined first procedure, and a key other than the owner key is operated in a predetermined second procedure other than the first procedure. a second detection means for detecting that the electric vehicle seat has been operated in the first step; and a second detection means for detecting that the electric vehicle seat has been operated in the first step; a first control means capable of storing the position of the electric vehicle seat in correspondence with a key other than the owner key when the second detection means detects that the electric vehicle seat has been operated in a second procedure; 1. A control device for an electric motor vehicle seat, characterized by comprising a second control means for controlling the vehicle seat. Therefore, since there is no need to provide a special secret switch, the number of parts can be reduced and the above problems can be solved.

Embodiment of the invention FIG. 1 is a schematic diagram of an electric seat system to which this invention is applied. In the figure, 1 is a driver's seat of a car, which is moved back and forth along a guide 3 by the rotation of a motor 2, and is moved back and forth by a motor 4.
moves up and down by rotating. 5 is a controller which inputs signals from a manual switch 6 provided on the side of the seat 1, position detectors 7, 8 for detecting the rotational positions of the motors 2, 3, and a pattern select switch board 9, and controls the motors 2, 3. Send a drive pulse to 3. The pattern select switch board 9 is provided with a memory key 9a, an owner key 9b, and keys 9c to 9e for storing seat positions of persons other than the owner. Further, 10 is a buzzer provided in the controller 5.

FIG. 2 is a block diagram of the main part of the controller 5. Reference numeral 20 denotes a microcomputer, which is connected via a bus 21 to peripheral circuits. 22 is a ROM for storing programs, etc.; 23 is a RAM; 24 is an interface circuit with the pattern select switch board 9, the manual switch 6, and the buzzer 10;
26 and 27 are drivers, the output of the driver 26 is sent to the motor 2, and the output of the driver 27 is sent to the motor 3.
guided by each. Further, 28 and 29 are counters that count output pulses from the position detectors 7 and 8.

When the seat movement key of the manual switch 6 is pressed, the microcomputer 20 causes the motor 2,
The current position of the seat 10 is stored in the RAM 23 by reading the values of the counters 28 and 29 that count output pulses from the position detectors 7 and 8 in parallel. When a predetermined storage operation to be described later is performed, the microcomputer 20 stores the current seat position in the RAM 23 in accordance with the pressed keys 9b to 9e of the pattern select switch board 9. Then, when any of the keys 9b to 9e on the pattern select switch board 9 is pressed, the microcomputer 20 stores the seat position information stored in correspondence with the pressed key.
The seat is read from the RAM 23, and the motors 2 and 3 are driven to move the seat to the pre-stored position so as to be equal to the seat position. Such an operation has been well known.

FIG. 3 is a flowchart showing an example of a software configuration for realizing the secret function of this invention, and S1 to S14 indicate each step. In this example, storage to the owner key 9b is performed using the storage key 9.
It is valid only when a is pressed a plurality of times, for example, three times, within a predetermined time, and the memorization in the owner key 9b is invalid other than that number of times, and the other keys 9c to 9
The storage in e is valid regardless of the number of times the storage key 9a is pressed. Memory operations other than the operation of the memory key 9a are the same as in the conventional method.

FIG. 4 is a flowchart showing another example of the software configuration for realizing the secret function of this invention, and S20 to S31 indicate each step.
In this example, the memory to the owner key 9b is valid only when the conventional simultaneous press memory operation method is performed, and the memory to the other keys 9c to 9e is valid only when the conventional separate press memory operation is performed. That is. Note that the memory to the owner key is stored using the memory key 9a.
Memories after releasing are invalidated, and when both are pressed at the same time, they are valid for a certain period of time, and are invalidated at other times.

Effects of the invention As explained above, in this invention, the operation of storing the seat position in the owner key 9b is different from the operation of storing the seat position in the other keys 9c to 9e. By keeping the storage operation for the owner key secret, it is possible to reliably prevent someone other than the owner from accidentally storing a different seat position to the owner key. Furthermore, the secret function is improved compared to the conventional case where a hardware secret switch is provided, and the number of parts can be reduced, making it possible to lower costs and improve reliability.
