The tilt motor 57 and the telescopic motor 75 constitute driving means, and are connected to the control box to control their driving.

FIG. 5 shows the passive belt 7. The passive belt 7 has a webbing 87 having one end wound around a retractor 83 and the other end connected to a slider 85. The slider 85 can slide along a rail 89 provided in the cockpit 1. That is, for example, the rail 89 is disposed along the edge of the vehicle door. One end of a wire (not shown) is connected to the slider 85, and the other end of the wire is connected to a drive motor 91. and,
By driving the drive motor 91, the slider 85 moves between the front and rear parts of the rail 89. Such movement of the passive belt 7 is controlled by a control unit 93, and the control unit 93 is connected to a control box (not shown) serving as υ control means.

The console box 95 is provided with an A/T device 97 for operating the vehicle and an operation panel 99 for setting the postures of the seat 3 and steering column 5. The A/T device 97 is in parking mode (
P), neutral mode (N) and driving mode (1,
2, D, etc.).

As shown in FIG. 6, the operation panel 99 includes a reclining switch 101, a slide switch 103, a front lift switch 105, and a rear lift switch 107. Further, the operation panel 99 includes a tilt switch 109 and a telescopic switch 111. Further, the operation panel 99 includes a memory switch 113 and a stop switch 115.

The reclining switch 101 and the slide switch 103 can be operated to the front side (F) or the rear side (B). In addition, the rear lift switch 105
, the rear lift switch 107, the tilt switch 109, and the telescopic switch 111 can be operated to the up side (U) and down side (1).

An operation panel 99 is connected to the control box. While the reclining switch 101 is being operated, the reclining motor 43 is driven, and the seat back portion 11 is tilted at a predetermined angle with respect to the seat cushion portion 9. By operating the slide switch 103, the slide motor 29 is driven, and the seat 3
moves forward and backward relative to the vehicle body.

In addition, by operating the front lift switch 105 or the rear lift switch 107, the front lift motor 3

By operating the telescopic switch 111, the telescopic motor 75 is driven, and the steering column 5 moves telescopically.

When the memory switch 113 is operated, the postures of the seat 3 and the steering column 5 whose postures have been changed by being moved by the respective switches can be stored on an IC card, which will be described later. Further, when the stop switch 115 is operated, the automatic setting operation, which will be described later, is stopped.

The instrument panel 117 has an IC card panel 1.
19 and a speaker 121 are provided. The IC card panel 119 is an IC card as a portable posture memory means.
A card insertion hole 125 for inserting or ejecting a card 123, a position switch 127, and an indicator lamp 12
9 is missing.

The IC card 123 stores, for example, driving posture information of the seat 3 and the steering column 5 in four memory positions. That is, for example, driving posture information for an individual during high-speed driving, low-speed driving, and city driving, or driving posture information for four people during normal times, etc., is set separately.

The card insertion hole 125 is located near the right lateral direction of the steering wheel 56. Therefore, the IC card 123
When the driver's right hand is inserted, the driver's right hand is in an extended state, and the webbing 87 of the passive belt 7 moving from the front of the rail 89 is prevented from interfering with the right hand, and can be securely placed on the driver.

Since the card insertion slot 125 is located on the extension of the driver's right shoulder,
Insertion and ejection of the C card 123 are performed naturally. The IC card panel 119 is provided with a known reading means (not shown) for reading the information stored in the IC card 123.

The position switch 127 is set to N8.1 to positive 4, and by turning on the position switch 127, the posture information stored in the memory position of the IC card 123 corresponding to the pedestal can be read.

The display lamp 129 includes, for example, an engine lamp 131, a position set lamp 133, and a warning lamp 135.
and a card error lamp 137. and,
Engine lamp 131 and position set lance 13
3 is lit in yellow, for example, and the warning lamp 135 and card error lamp 137 are lit in red, for example.

Such reading means, position switch 127 and display lamp 129 are connected to the control box 93.

The speaker 121 is located above the steering column 5, for example, and is configured to emit audio, warning sounds, and the like.

Further, 139 is a brake pedal, and when the brake pedal 139 is operated, a brake detection switch (not shown) is turned on.

Next, the operation will be explained based on flowcharts not shown in FIGS. 8 to 15. The program shown in this flowchart is repeated at predetermined intervals.

First, while the driver is in the car, sitting on the seat 3 and the seating sensor is on, insert the IC card 123 into the card insertion hole 1.
25, the card error lamp 137 turns on and a voice saying "Please set the card" is heard from the speaker 121 (step 3101).
to step 8107).

Then, such sound is repeated for two seconds (steps 5109 and 5111).

When the tC card 123 is set in the card insertion hole 125, the card error lamp 137 is turned off (step 8).
113).

When riding, the engine is off and the shift lever 98 is also in parking, so the shift lever 98 is locked and the timer is reset to O (step 511).
5 and steps 5119 to 5121).

In this state, when any of the position switches 127 is turned on, the driving posture positions of the seat 3 and steering column 5 corresponding to the positive state of the turned-on position switch 127 are read from the memory positions of the IC card 123 (steps 5121 to 512). 8135).

Note that when none of the position switches 127 is operated, it is assumed that the high 1 position switch 127 has been operated, and the process proceeds. Also, position set lamp 1
33 is turned on, and a warning sound is generated from the speaker 121 (steps 5137 and 5139).

Then, in step 5141, the driving posture of the seat 3 is automatically set. That is, as shown in the subroutine in FIG. 12, when the current position of the seat 3 is not at the driving position read from the IC card 123, the slide motor 29, front lift motor 33, and The rear lift motor 34 and the reclining motor 43 are turned on (step 8301 and step 8303).

At this time, when the stop switch 115 on the operation panel 99 is operated, the motor is turned off (steps 5305 and 311). Thereafter, the current position of the seat 3 and the driving posture position are compared, and each motor is turned on until the deviation becomes 0 (steps 5307 to 8303).

Next, 2.2 seconds after the IC card 123 is set, the driving posture of the steering column 5 is automatically set (step 5143 and step 8145). At step $145, as shown in the subroutine in FIG. 13, the tilt motor 57 and the telescopic motor 75 are driven as in the case of the seat 3 (steps 5401 to 8411). In this way, by shifting the attitude change of the steering column 5 by two seconds from the attitude change of the seat 3, it is possible to suppress the current flowing at one time and protect the battery.

Then, in step 5147, the slide 85 slides from the front to the rear of the rail 89, and the passive belt 7 is changed to the driving position.

In addition, even if the stop switch 115 is operated to change the posture of the passive belt 7, the operation will not be stopped midway.

When the seat 3, steering column 5, and passive belt 7 are changed to the driving position in this way, the position set lamp 133 is turned off (step 5149).
, the warning sound from the speaker 121 is turned off (step 8151), and the end flag is set (step 81
53).

Here, if the key is not set, a voice saying "Please set the key" is heard from the speaker 121 (steps 5155 and 5159).

Then, when the engine is turned on, the engine light 13
1 is turned on and the IC card 123 is locked (steps 8160 to 8175). Therefore, the IC card 123 cannot be removed when the engine is on.

Then, when the brake switch is turned on, the shift lever
98 is unlocked and it is possible to switch from parking mode to driving mode.

(Step 8165 and Step 3167). after that,
The program ends. Therefore, after the seat 3, steering column 5, and passive belt 7 have been changed to the driving position, the switching becomes possible by operating the brake, and the vehicle can be driven.

Therefore, while changing the position to the driving position, the shift lever 98
For example, it is possible to prevent the shift lever 98 from malfunctioning while the seat 3 is being moved, thereby ensuring the safety of the A/T device 97 in an automatic vehicle.

Here, the brake switch is off and manual switch 1

57 and 75 are driven (step 5171 and step S'173). Thereafter, by operating the memory switch 113, the memory lamp (in this embodiment, the corresponding position set lamp 133 blinks) is turned on, and the current positions of the seat 3 and steering column 5 are stored in the IC card 123. (Step 5175
to step 197).

Note that such memory operations can be performed using position switch 1.
27 to each memory position of the IC card 123. After that, the memory lamp turns off after 2 seconds (steps 8181 to 8185).
), the program ends in the same manner as when the memory switch is turned off in step 5171.

Then, when the program starts, step 511
At step 7, the shift lever 98 is in the running mode, so the process advances to step 8118. Then, when the position switch 127 is operated again, the process proceeds to step 5123, while
The program will terminate if no action is taken.

Thereafter, in step 5119, the shift lever 98 is switched from the driving mode to the parking mode or neutral mode, and if the IC card 123 is not removed from the card insertion hole 125 in step 5191, the process proceeds to step 8101.
Once taken out, the timer becomes 0 (step 8193). The slider 85 moves from the rear of the rail 89 to the front, and the passive belt 7 is automatically set to the retracted position (step 8195). In step 5197, the seat 3' is automatically set to the retracted position. That is, as shown in the subroutine in FIG. 14, the slide motor 29.
The front lift motor 33, the rear lift motor 34, and the reclining motor 43 are driven in the reverse direction from those in step 5141 (steps 5501 to 8511).

For example, the seat 3 slides to the rearmost position, lifts to the lowest position, and reclines to the neutral position.

Thereafter, the steering column 5 is automatically set to the retracted position after 2 seconds (steps 5199 and 8).
201). That is, as shown in the rib routine in FIG. 15, the tilt motor 57 and the telescopic motor 75 are driven in reverse from step 5145 (step 5601).
to step 8611). For example, the tilt moves to the highest position and the telescope moves to the front.

If the engine is on, the process proceeds to step 5191, and if the engine is off, the engine lamp 131 is turned off and the I
The C card 123 is unlocked, a voice saying "Please take the card" is heard from the speaker 121, and the shift lever 98 is unlocked (steps 8205 to 5213).

The key remains locked when the shift lever 98 is not in the parking mode, and is unlocked when the shift lever 98 is in the parking mode. Then, when the driver gets off the seat 3 without removing the key, a warning sound for forgetting to use the key is heard from the speaker 121 (steps 5223 to 8227).

At this point, unless the driver gets off the seat 3, the ``Y'' message for forgetting to use the key will not be played (step 8229). Furthermore, when the driver removes the key and gets off the seat, the program ends (step 8231>).

As described above, according to this embodiment, simply by the driver sitting on the seat 3 and inserting the IC card 123 into the card insertion hole 125, the seat 3, steering column 5, and passive belt 7 can be easily adjusted to the driving position. Change your financial resources. Therefore, in addition to being able to start quickly, riding comfort is also good because the driver's posture is changed after getting on the vehicle. On the other hand, since the steering column 3, steering column 5, and passive belt 7 are changed to the retracted position when the driver gets off the vehicle, a space for the driver to get out of the vehicle is secured and the ease of getting out of the vehicle is good.

Note that the present invention is not limited to the above-mentioned embodiments, and for example, an optical card, a laser card, a magnetic card, etc. may be used instead of the IC card 123 as the posture memory means.
It goes without saying that there may be a single memory position or four or more memory positions.

Further, the motors for lifting the seat 3 do not necessarily need to be provided independently in the front and rear, and may be provided only in the front or the rear.

Further, the seat 3, the steering column 5, and the passive belt 7 do not need to be changed to the retracted position when the driver gets off the vehicle, as long as the driving position is set when the driver gets on the vehicle.

Moreover, the same effect can be obtained even with a configuration in which, for example, only the seat 3 and the steering column 5 or only the seat 3 are changed in posture, without changing the posture of all of the seat 3, the steering column 5, and the passive belt 7.

[Effects of the Invention] As explained above, according to the present invention, the posture information stored in the portable posture storage means is read after the driver gets into the vehicle, and the posture of the seat etc. is changed to the driving posture based on this posture information. What was the configuration? Therefore, although the configuration allows the driving position of the seat etc. to be easily obtained, riding comfort can also be improved because the driver's position is changed after getting on the vehicle.
