Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle that improves riding comfort for a driver, for example.
This article relates to 11 devices for controlling posture.

[Prior Art] As a conventional on-vehicle attitude control device of this type, there is one described, for example, in Japanese Patent Application Laid-Open No. 58-33569. That is, it is equipped with an electronic control device that stores and holds the steering wheel attitude information at that point in time in response to the operation of the memory support switch means, and when the driver's getting on and off operation is detected, the steering wheel is positioned at the retracted position and the steering wheel is moved to the retracted position. When it is detected that a person has boarded the vehicle, the steering wheel operating position stored in the electronic control unit (
For example, by positioning the vehicle at the previous driving position of the driver, the driver can easily get on and off the vehicle.

[Problems to be Solved by the Invention] However, in such conventional on-vehicle attitude control devices, in order to make getting on and off operations easier, the steering wheel The evacuation position of the vehicle was set at the furthest position from the driver. For this reason, when you take turns riding,
The latest driving position stored in the electronic control unit cannot be determined just by looking at the retracted position of the steering wheel.
For example, if the previous driver had adjusted the tilt position to the lowest position, or if the driver taking turns is larger than the previous driver, the steering wheel will automatically adjust to the previous driving position. When this change is made, the driving position has to be significantly changed to the lowest position to suit the previous small-sized passenger, and then readjusted to the current driving position to suit the large-sized passenger, making the operation complicated. There will be a lot of unnecessary movement in the device. Furthermore, if the adjustment is made to the lowest position suitable for a small-sized passenger in the previous position, there is a problem in that a large-sized passenger must take an unreasonable posture.

Therefore, the present invention provides an on-vehicle posture in which the retracted posture of on-vehicle equipment is changed by a predetermined amount of displacement with respect to the driving posture, and the on-vehicle posture can predict the driving posture by looking at the retracted posture when getting on the vehicle. The purpose is to provide a control device.

[Means for Solving the Problems] An on-vehicle fixture Q whose position can be changed between a driving position and a retreat position whose settings can be changed, a drive means MO for changing the attitude of this on-vehicle fixture Q, and the above-mentioned on-vehicle fixture Q. posture detecting means SCI for detecting the posture of the passenger, posture storing means ME for storing the posture of the on-vehicle equipment Q detected by the posture detecting means SC1, and riding completion state detecting means SC2 for detecting the riding completion state of the occupant.
and a control means CO for controlling the attitude change of the on-vehicle equipment 0.
The control means CON changes the attitude of the on-vehicle equipment Q from the driving position to the retreat position by a predetermined constant displacement amount, and the control means CON changes the position of the on-vehicle equipment Q by a predetermined constant displacement amount by the detection of the ride completion state detection means SC2. The configuration is configured to control the amount of displacement to change the position from the retracted position to the driving position.

[Operation] According to the above configuration, the attitude change of the on-vehicle equipment from the driving attitude to the retreating attitude is performed by a predetermined constant displacement amount ().

[Example 1 The present invention will be described in detail below.

FIG. 2 is a circuit diagram in which an electronic control device for an on-vehicle attitude control system according to an embodiment of the present invention is constructed using a microcomputer, and FIG. 3 is a flowchart based on the circuit shown in FIG. g52.

A vehicle equipped with such an on-vehicle attitude control device is equipped with a steering wheel 5wff1i shown in FIG. 4 as an example of on-vehicle equipment Q, and this steering wheel SW
The structure is such that the position can be changed between a driving position and a retreating position. In this case, when the microcomputer 1 automatically changes the posture of the steering wheel SW from the driving posture to the retreated posture, the posture is changed by a predetermined displacement amount by the microcomputer 1.

This amount of displacement can be set arbitrarily,
It is also possible to display.

Here, the microcombination L-1 as the control means CON and the attitude storage means ME includes a CPU, ROM, and RAM.
This is a so-called general-purpose microcomputer configured in a one-touch LS1, which reads necessary information according to a program stored in a well-known 1 (OM), performs predetermined processing, and issues an output signal.

An input port of the microcomputer 1 is connected to engine key switches 3 and 5, a manual adjustment switch 7, and a storage instruction switch 9.

Further, the input side port of the microcomputer 1 includes a steering tilt amount detection sensor 11 and a steering tilt amount detection sensor 13 .
and steering wheel drive cancel switch 1
5 is connected.

On the other hand, relays 17, 19, 21, and 23 are connected to the output side port of the microcomputer 1. relay 1
7.19 is a steering wheel 1 to a motor 2 as a driving means MO for changing the attitude of the steering wheel SW.
5, the relays 21 and 23 are connected to a steering telescopic motor 27 as the driving means MO.

The steering wheel SW is as shown in Figure 4.
By driving the motor 25, the shaft 101 is driven back and forth to tilt the steering wheel SW, and by driving the motor 27, the shaft 102 is moved back and forth to telescope the steering wheel SW.

The engine key switches 3 and 5 have the functions of an alighting motion detecting means for detecting a dismounting motion of an occupant, and a boarding completion state detecting means SC2 for detecting a state of completion of aboard the vehicle. That is, the key switch 3 detects the presence or absence of a key,
4-Switch 5 detects whether the ignition is on or not. When the key is removed, both switches 3 and 5 are open, and when the ignition is on, both switches are open.

The manual adjustment switch 7 consists of a movable contact 29.31 and fixed settings 33.35, 37.39. The movable contact 29 can be selectively connected to the fixed setting 33.35, and the movable contact 31 can be selectively connected to the fixed setting 37.39. Fixed contacts 33.35, 37.39 are also responsive to the relays 17.19.21.23, respectively.

The manual adjustment switch 7, the relays 17 to 23, the steering tilt motor 25, and the steering telesco motor 27 constitute driving means for the steering wheel SW.

The storage instruction switch 9 includes a main switch 41 and a first memory position switch 43 . It consists of a second memory position switch 45. The first and second memory position switches 43 and 45 store the vehicle posture such as the steering wheel position during driving.
The configuration is such that the information is stored separately in the memory area and the second memory area.

This first and second memory position switch 43.45
, a momentary open type switch, one end of which is grounded, and the other end connected to the microphone coco computer 1 via an inverter.

Furthermore, apart from the first memory area and the second memory area, the microcomputer 1 stores information on the vehicle after the operation of the steering wheel driving means is completed in response to the operation of the manual adjustment switch 7 without the operation of the storage instruction switch 9. It has a third memory area that stores the posture using pulse signals from the steering tilt amount detection sensor 11 and the steering telescopic amount detection sensor 13, which are the posture detection means SC1. Therefore, this third memory area is the posture detecting means SC1.
An attitude storage means ME is configured to store the attitude of the on-vehicle equipment Q detected by.

The steering wheel drive cancel switch 15 is
When this is turned on, the microcomputer 1 transmits the relays 17 to 23 regardless of the on/off signal of the key switch 5.
The steering tilt motor 25 and the steering telescopic motor 27 are configured to cancel the output of the signal to prevent the steering tilt motor 25 and the steering telesco motor 27 from operating.

Note that the reference numeral 47 in the figure is a power supply circuit.

Next, the driver adjusts the position of the steering wheel SW on the vehicle (
■Explain when to adjust at will.

This is done by turning on the engine key switch 3.5 and then arbitrarily operating the manual adjustment switch 7.

That is, when adjusting the vertical angle position of the steering wheel SW, the movable contact 29 is connected to the fixed contact 33 or 35, for example. Here, when the movable contact 29 is connected to the fixed contact 33, a signal from the fixed contact 33 is input to the microcomputer 1, and this input causes the microcomputer 1 to output an output signal to turn on the relay 17 corresponding to the fixed contact 33. issue. When the relay 17 is turned on by this output signal, the steering tilt motor 25 rotates forward to move the steering wheel SW to the retracted position (
(ascend) to change posture. On the other hand, when the movable contact 39 is connected to the fixed contact 35, a signal from the fixed contact 35 is input to the microcomputer 1, and this input causes the microcomputer 1 to turn on the relay 19. When the relay 19 is turned on, the steering tilt motor 25 is reversely rotated to change the posture of the steering wheel SW to the driving position (downward).

Note that such rotational drive of the steering tilt motor 25 is performed only while the movable contact 29 continues to be connected to the fixed contact 33 or 35, and therefore, the steering wheel SW maintains the same attitude in the neutral state.

In addition, when adjusting the forward/backward position of the steering wheel SW, by connecting the movable contact 31 to the fixed contact 37 or 39, the microcomputer 1 and the relay 2
1 or 23, the steering telescopic motor 27 is rotated in the forward and reverse directions to change the posture of the steering wheel SW between a retracted position (a position away from the driver) and a driving position (a position close to the driver).

In this way, the steering wheel SW position adjusted by the driver (owner-driver, etc.) can be stored in the microcomputer 1 by manually operating the manual adjustment switch 7. That is, for example, after turning the main switch 41 to f'+: L/, the first memory position switch 4 is turned on.
3, the pulse signals from the steering tilt amount detection pin '+J11 and the steering telescopic amount detection sensor 13 are input to the microcomputer 1, and this input causes the first memory position switch 43 to be turned on. It is stored in the memory area as the on-vehicle attitude.

This storage is performed by counting the number of pulse signals from the steering tilt amount detection sensor 11 and the steering telescopic amount detection sensor 13 using a counter, respectively, and storing the counted value of this counter as a reference value.

Further, the on-vehicle attitude of the steering wheel SW can be determined by each sensor 11 even without operating the memory instruction switch 9.
．． The count value of the counter that counts 13 pulse signals is stored in the third memory area of the microcomputer 1 as the current on-vehicle attitude.

Thereafter, when the manual adjustment switch 7 is operated again to select another on-vehicle attitude and this on-vehicle attitude is to be stored, the procedure is as follows. That is, by turning on the main switch 41 of the storage instruction switch 9 and then turning on, for example, the second memory position switch 45, this operation is performed in the same manner as when the first memory position switch 43 is operated. The on-vehicle attitude at that time is stored in the second memory area.

Since the on-vehicle attitude at this time is different from the on-vehicle attitude stored in the third memory area of the microcomputer 1, the on-vehicle attitude at this time is stored in the third memory area as the latest position. .

In this way, each memory position switch 43.4
By operating 5, different postures can be stored in the corresponding memory areas of the microcomputer 1, and the latest on-vehicle posture can be stored in the third memory area of the microcomputer 1. Can be done.

By the above operation, the microcomputer 1. When reproducing the on-vehicle posture stored in the first memory area and second memory area of
By turning on the switch corresponding to the memory area desired to be reproduced, the steering wheel SW can be positioned in a desired position on the vehicle.

The above is about the on-vehicle attitude of the steering wheel SW, but the on-vehicle attitude of, for example, the slide, lift, reclining, lumbar port, side support, thigh support, outside door mirror, or room mirror of Sea 1~ is also controlled in the same way. can.

Next, the control action of the above embodiment will be explained based on the flowchart shown in FIG.

First, the operation of getting off the vehicle will be explained.

With the above configuration, the snowtube S1 determines whether the engine key switches 3 and 5 are on or off. Here, when the engine key switch 3.5 is turned off when the driving position is relieved, the process proceeds to step S2, and it is controlled whether or not the steering wheel SW has changed its position from the driving position to the retracted position. When the driver gets out of the car, the steering wheel S
Since W is in the driving position, the answer in step S2 is No, and the process proceeds to step S3, where it is determined whether the steering wheel drive camphill switch 15 is on. If the steering wheel drive cancel switch 15 is off, the process proceeds to step S4, where the counter value of the pulse signal from the steering tilt amount detection sensor 11 and the same telescopic amount detection sensor 13 and the steering wheel drive cancel switch 15 set in advance by the microcomputer 1 are used. Displacement amount for SW forward/backward posture (for example, 4° for tilt amount, 20° for telescopic foot)
A comparison is made with the counter value n). Step S1
1, it is determined whether the deviation between the current counter value of the tilt/telescope of the steering wheel SW and the counter value for the retracted attitude set by the microcomputer 1 is O. Step 811 is N.

In this case, proceed to step 812 and relays 17 and 21
is turned on, and the steering tilt motor 25 and steering telescoping motor 27 are driven to avoid changing the attitude of the steering wheel SW to the retracted attitude.

Since the microcomputer 1 sets it in step S4 as described above, the retracted posture of the steering wheel SW (
(position away from the driver) is the steering wheel S
With respect to the current position of W, that is, the driving posture, a predetermined constant tilt amount (e.g., 4° rise) and telescopic foot (
For example, the tilt/tele position is shifted by 20 mm (forward movement). If the driving position is changed by a certain amount, the ease of getting in and out of the vehicle can be sufficiently improved without changing to the farthest position.

Further, unnecessary movement of the steering wheel SW is eliminated, and the durability of the device is also improved.

On the other hand, if step 811 is YES, the process proceeds to step 813, where the relays 17 and 21 are de-energized and turned off, an end flag is set in step S14, and the process returns to step S1.

If step S3 is YES, that is, the steering wheel drive cancel switch 15 is on, the process advances to step S5, where the end flag is set to Sera 1~, and step S1
Return to. Note that the switch 15 is almost never turned on when getting off the vehicle.

Next, when the driver gets on the vehicle, the steering wheel SW is positioned in the same retracted position as the riding position. Therefore, if the same driver as the previous driver gets in the vehicle, it can be determined by looking at the retracted posture of the steering wheel SW that the driver's own driving posture will be changed after getting in the vehicle. Then, when engine key switch 3.5 is turned on, step S1 is YFS.
The process then proceeds to step S6, where it is controlled whether or not the steering wheel SW has changed its position from the retracted position to the driving position.

If step S6 is YES, the process proceeds to the normal memory and memory return routine of step S7, and if NO, the process proceeds to step S8, where it is controlled whether or not the steering wheel drive cancel switch 15 is on. and,
If the steering wheel drive cancel switch 15 is off, the process advances to step S10 and the current steering tilt amount detection sensor 11 and the current steering wheel drive amount detection sensor 1 are
The counter value of the pulse signal from t19.3 and the operation of the steering wheel SW stored in the third mail area of the microcomputer 1. The posture (previous driving posture) is compared with the counter value, and it is determined in step S11 whether the deviation is 0 or not. At this time, there is a deviation between the steering tilt position and the same telescopic position, so step 8
12, the relays 19 and 23 are turned on by the output signal of the microcomputer 1, and the steering tilt motor 25 and the telescopic motor 27 are driven until the deviation becomes O. Then, in step 811, if it is determined that the deviation becomes 0 and matches the counter value stored in the third memory area of the microphone [1 computer 1, step 81
3, the energization of the relays 19 and 23 is cleared and turned off, an end flag is set in step 814, and the process returns to step S1. In this way, the Φ upward position (driving position) of the steering wheel SW before getting off the vehicle is regenerated, and riding comfort is significantly improved.

If step S8 is YES, that is, the steering wheel driving camphill switch 15 is on, an end flag is set in step S9, and the normal menu and memory return routine of step S7 is performed. In addition,
When the same person rides the vehicle, the switch 15 is rarely turned on.

Next, when the driver takes turns getting on the vehicle, the current position (retracted position) of the steering wheel SW is a position changed from the previous driving position by moving a certain amount of tilt and telescopic amount. Therefore, the previous driving posture can be easily predicted.

Therefore, if the predicted driving position has sufficient margin for the physique of the driver in question, the engine 4 knee switch 3.5 is turned on, and steps 81 to S are performed.
14 is executed, and the posture is changed to the driving posture. after that,
An appropriate driving posture may be achieved by operating the manual adjustment switch 7.

Furthermore, if the predicted driving position does not have enough room for the physique, first turn on the steering wheel drive cancel switch 15 to cancel output of signals to the relays 17 to 23.

Then, when the engine key switches 3 and 5 are turned on, the process proceeds to step S6, and since step S6 is No at this time, the process proceeds to step S8. In step S8, since the steering wheel drive cancel switch 15 is turned on, the process proceeds to step S9, where the end flag is set to 1~, and the routine returns to the normal memory and memory return routine of step S7.

Therefore, by arbitrarily operating the manual adjustment switch 7, the on-vehicle attitude of the steering wheel SW can be adjusted to suit the driver. This eliminates the need for the steering wheel SW to change its position significantly to suit the driver in front of it, eliminates unnecessary movement, improves durability, and allows manual adjustment by the driver. It becomes easier. Also, the steering wheel SW
There is no need for the occupants to be pinched or forced into an unreasonable position due to large tilt or telescoping movements.

In addition, in the embodiment described above, the steering wheel drive device was configured to operate only in conjunction with the on/off of the engine key switch 3.
It may also be set when both conditions are off. Furthermore, the present invention can also be applied to a vehicle that takes into account only rideability, as described in Japanese Patent Application Laid-Open No. 59-227536. Further, in the above-described embodiment, only the retracted position of the steering wheel has been described, but the invention is of course not limited to this and can be applied to on-vehicle accessories such as seat mirrors.

[Effects of the Invention] As is clear from the above description, according to the configuration of the present invention, when a passenger gets on board, the driving position can be predicted by looking at the retracted position of the onboard equipment, and even when the driver is replaced, the vehicle To improve the durability of upper fixtures without moving them unnecessarily, to reduce the amount of readjustment, and to facilitate operation. Further, the occupant is not forced to take an unreasonable posture.
