[0079]

[Table 2]

The control gain coefficients corresponding to the 5 subitems of the A term in the data input item list are as shown in Table 1, and the 3 subitems of the B term, 2 subitems of the C term, and the D term of the D term. The control gain correction coefficients corresponding to the three small items are as shown in Table 2, and the contents of Table 1 and Table 2 are stored in advance in the ROM 61 as a table accompanying the control program of the ROM 61. Basically, the control gain coefficient is set in the range of 0.8 to 1.2, as can be seen from Table 2, from the viewpoint of preventing a large change in the characteristics of the automobile.

Here, regarding the control gains of EGI and EAT, the control gain "small" is in the direction of low fuel consumption and the control gain "large".
Is the direction of increasing power. Regarding the control gain of ACS,
The control gain "small" is the riding comfort increasing direction (soft direction), and the control gain "large" is the steering stability improving direction (hard direction). Regarding the control gain of 4WS, the control gain “small” is in the small turning property increasing direction (reverse phase gain increasing direction), and the control gain “large” is the steering stability increasing direction (in-phase gain increasing direction). Regarding the control gain of P / S,
The control gain "small" is the direction in which the steering force is light, and the control gain "large" is the direction in which the steering force is heavy.

The control gain coefficient of the five small items of the A term of Table 1 is a correction coefficient which is set in common to the respective control devices 14, 16 to 18, and is the control gain correction coefficient (control gain coefficient) of Table 2. It corresponds to a common control gain coefficient for correcting the correction component determined by, and the control gain coefficients of B term, C term, and D term in Table 2 are
Since the correction coefficients are independently set in the respective control devices 14, 16 to 18, they correspond to the individual control gain correction coefficient.

Next, regarding the control gain coefficient illustrated in Table 1, as a general tendency, the gain coefficient "small" is in the direction of decreasing the control gain correction amount, that is, the direction close to the base control gain, and the gain coefficient "large" is in the control gain correction. The control gain coefficient is set to a small value in the direction of increasing the amount, that is, in the direction away from the base control gain, and for women, young people, elderly people, people with less than 1.5 years of car history, etc. Also, for those aged 21 to 30 and those with a car history of 5 years or more,
The control gain coefficient is set to a large value in view of good driving, and when the number of owned vehicles is one or the owner other than the owner also uses it, the control gain coefficient is small in consideration of being used by a plurality of persons. It is set. Next, regarding the control gain coefficient illustrated in Table 2, considering the low μ and the increase in oil viscosity in cold regions, the commuting type enhances the feeling of a saloon car, and the leisure type enhances the steering stability and sports. The control gain coefficient is set from the viewpoints of increasing the car orientation, and improving the fuel efficiency and the small turning ability for shopping and sales.

Here, in the data input item list shown in FIG. 10, the fields for inputting “0” and “1”, that is, the first subitem and the D item of Table 1 item A and Table 2 item B are controlled. One gain coefficient is determined from Table 1 and Table 2 as a1 to a5, b1, and d1 to d3, respectively. However, the column for entering the "rank", that is, the second item of the B term in Table 2 For the sub-item, the third sub-item, and the C term, the values of the control gain coefficient in Table 2 are used.
The control gain coefficient is determined by calculation in consideration of the weight of rank as follows. In this case, 40% weight for 1st place, 30% weight for 2nd place, 20% for 3rd place
Control weighting coefficient is calculated by giving 10% weighting to the 4th place.

For example, in the second subitem of item B, if the ranking is urban (1st), suburbs (2nd), rural (3rd) and mountainous (4th), The control gain coefficient b2 of the two small items is calculated for each control gain coefficient of the control devices 14 and 16 to 18 by weighting b21 to b24. b2 = 0.4 xb21 +0.3 xb22 +0.2 xb23 +0.1 xb24 The control gain coefficient b3 of the third sub-item of B term is also weighted in the same order as above, and EGI, ACS, 4WS, It is calculated for each control gain coefficient of P / S, and the control gain coefficient c1 of the first small item of the C term is also weighted in the same order as above by using the coefficients c11 to c14, and EGI, ACS , 4WS, P / S is calculated for each control gain coefficient, and the control gain coefficient c2 of the second subitem of the C term is also weighted in the same manner as described above using the correction coefficients c21 to c24. , EGI, ACS, 4WS, P / S are calculated for each control gain coefficient.

Next, in S38 of FIG. 31, EGI, ACS, and
Control gain factors b2e, b2a, b2w, b2 for 4WS, P / S
p, control gain coefficients b3e, b3a, b3w, b3p, control gain coefficients c1e, c1a, c1w, c1p, and control gain coefficient c
2e, c2a, c2w, c2p are calculated by adding the weighting of the rank as described above. The suffixes e, a, and
w and p correspond to EGI, ACS, 4WS, and P / S, respectively. Thus, from the input data and the calculation result of S38, EGI, ACS, 4WS,
The control gain coefficients of all items in Table 2 regarding P / S are determined.

As a result of the determination, if it is not the accessory mode, S1
At 52, the setting of the made-to-order characteristic, the setting of the system characteristic, and the device setting for the one-touch SW are prohibited, then a message of prohibition of setting is displayed on the display 71 in S153, and then the process ends.

Here, since all the control programs and data set in the gain changer 20 are transmitted to the control device 90 to be transplanted, when utilizing only the characteristics set in the gain changer 20, the control device 90 is used. It is not necessary to execute the setting of S151 in. However, if it is desired to change the control gain characteristics after actually running after the data is transplanted to the control device 90, the control gain characteristics and the like can be changed through the setting control of the control gain characteristics and the like in S151. Further, the data received from the gain changer 20 can be erased by operating the data erase key,
Also in this case, the control gain characteristic or the like can be set through the setting control of the control gain characteristic or the like.

When the latest flag is reset by operating the return SW, the flag immediately before the latest flag is updated to the latest flag. However, when the mode release key is operated, all the set flags are reset.

In S183 after S182, control signal output processing for outputting control signals corresponding to various flags is executed, and then the process returns. On the other hand, if the result of determination in S181 is that the vehicle speed V is 0, in S184 a flag is set according to the switch operation on the one-touch SW screen 21I. In this case, the start SW is ON

In the above-described control gain changing system for a vehicle control device, EGI, ACS, 4WS, P based on a plurality of driver-specific data relating to driving characteristics and usage conditions of the owner driver.
Since the base control gain of / S can be changed to change the control characteristics of the vehicle so as to match the owner driver, it is possible to obtain the easy-order characteristics desired by the owner driver. Moreover, the owner driver inputs the data relating to the driving of the driver into the gain changer 20 while looking at the screen of the display 22 at home or the like, and obtains the data of the control gain coefficient calculated based on the input data. Since it can be transplanted to the gain changing device 70 of the automobile by wireless transmission, it is a much simpler device as compared with the learning control system, and at a low cost, substantially the same technical effect can be obtained.

Further, in this control gain changing system,
The set control gain characteristics of the control devices can be displayed on the display 21 and can be confirmed, and the control gain characteristics can be appropriately changed if desired, which is excellent in practicality. In addition, the control gain characteristics set for the owner driver are configured to be controlled by the control gain change allowable range set by a specialist by observing the test drive when purchasing a vehicle, so the owner driver sets the control gain characteristics. Even if set improperly, a control gain characteristic suitable for the driving skill of the owner driver can be obtained. The above-mentioned specialist sets the control gain coefficient of the primary characteristic based on the driving skill and wishes of the owner driver, and also selects this control gain coefficient so that it can be applied. It is possible to adopt the primary characteristic in which the change width of the control gain is large.

Further, in this control gain changing system,
Since the "one-touch SW" mode is provided and a plurality of control gain characteristics desired by each of the owner driver and other drivers and the control gain characteristics suitable for the usage state of the vehicle can be appropriately set, the versatility is excellent. Further, in this control gain changing system, a "one-touch SW" mode is provided to set the operation mode of a plurality of devices in each of a plurality of specific operation states (starting, starting inspection, parking, ... Etc.) of the automobile. By storing and operating the one-touch SW, it is possible to simultaneously operate a plurality of devices in their respective operation modes set, so that the operability is excellent and the device is easy to use.

Further, since the data can be transmitted from the gain changer 20 to the control device 90 by the wireless transmission method, the gain changer 20 can be operated inside or near the automobile so that the device from the gain changer 20 can be operated. A command signal such as an operation signal can be supplied to the control device 90. Further, since the data set in the control device 90 can be transmitted to the gain changer 20, the data of the control gain characteristic is transferred to the gain changer 20 after the operation of the automobile is finished, and the gain is changed via the gain changer 20 at home or the like. It is also possible to appropriately change the control gain characteristic. Moreover, since the gain changer 20 can output the display to the TV receiver, it is possible to enjoy the fun while watching the TV screen while enjoying the leisure time, and it is possible to set or change the control gain characteristic. Since information can be output, it becomes easy to input data, change operation settings for changing control gain, change settings, and understand control characteristics. Furthermore, when the vehicle is in a specific state other than the normal running state (vehicle speed is a predetermined value or more, lateral acceleration is a predetermined value or more, low μ road running or bad road running), when the system fails, or when the fuel level is low. In addition, the application of the control characteristic of the primary characteristic and the custom-made control characteristic is prohibited, and the manufacturer-set control characteristic is applied, so that the steering stability can be secured.

Next, various modified examples in which a part of the above embodiment is modified will be described. 1] Instead of the evaluation discrimination control (FIGS. 47 and 48) displayed on the control gain evaluation screen 21R, the following evaluation discrimination control may be applied (see FIGS. 49 and 50). As shown in FIG. 49, when the evaluation determination control is started, first, the data of the corrected control gain coefficient (FKe, FKt, FKa, FKw, FKp) is read (S300), and then in S301, These control gain coefficients (FKe, FKt, FKa, FKw, FKp)
Of each deviation Δ from 1.0 to 1.0 corresponding to the base control gain
e, Δt, Δa, Δw, Δp and the average deviation Δm of these deviations are calculated by the calculation formula shown. Next, in S302, the percentage of the deviation Δe, Δt, Δa, Δw, Δp with respect to the average deviation Δm with respect to the average deviation Δm (this is referred to as deviation degree) is calculated by the illustrated arithmetic expression.

The deviations Δe, Δt, Δa, Δw, Δp indicate the degree of control gain change with respect to the base control gain, and the deviation degree is the average deviation Δm of the deviations Δe, Δt, Δa, Δw, Δp. It indicates the degree of change to the. Next, in S303 to S312, the absolute value of the deviation degree is 10
When it becomes larger than 0, the control gain coefficient (FKe,
FKt, FKa, FKw, FKp) is determined to have been set incorrectly.
In other words, for each control gain coefficient (FKe, FKt, FKa, FKw, FKp), if the deviation degree is larger than 100 or smaller than −100, the change range of the control gain coefficient is For the change width of the control gain coefficient of
The setting is remarkably large or small, and the control gain is changed unbalanced as a whole.

Therefore, in S313, as a desirable value range of the control gain coefficient, a desirable value range of the control gain coefficient is set so that the deviation of each control gain coefficient is a value within 100% of the average deviation. In this case, when the average deviation Δm is negative, the desired value range of the control gain coefficient is calculated as (2Δm + 1.0) to 1.0,
When the average deviation Δm is positive, the desired value range of the control gain coefficient is calculated to be, for example, 1.0 to (2Δm + 1.0). Next, in S314, as shown in FIG. 50, the deviation degree of the currently set control gain coefficient, the name of the control device corresponding to the erroneously set control gain coefficient, and the erroneously set control gain coefficient are desirable. A display control signal for displaying the value range on the display 21 is output to the display controller 22, and then this calculation process ends. Therefore, by referring to this evaluation screen, the control gain coefficient of erroneous setting and its desired value range can be known, and the setting can be changed.

2] Instead of the data input item list shown in the data input item screen of FIG. 10, a data input item list shown in the data input item screen 21T shown in FIG. 51 can be adopted. This data input item list is of a type in which the control gain coefficient is directly input and set, and is suitable for a driver who has a considerable knowledge of automobiles. As shown in the figure, the engine characteristics (intake amount, fuel injection amount, Ignition timing), automatic transmission gear change characteristics, brake characteristics, traction control TCS control characteristics, antilock brake control ABS characteristics, power steering characteristics,
For each of the items such as rear wheel steering characteristics and air conditioning characteristics, 0.8,
All or part of the control gain coefficients of 0.9, 1.0, 1.1, 1.2 are listed, and one control gain coefficient is selectively input for each item.

When inputting data in the state of being displayed on the display, the desired control gain coefficient is designated by the cursor and the execution key is operated to input.
Then, after the data input of the items A to H is completed, the set control gain coefficient is stored in the RAM 62, the data is transmitted and output to the control device 90, and the RA of the control device 90 is output.
Stored in M92. The control device 90 controls the control gain change signals corresponding to the control gain coefficients, respectively.
14 to 18, the braking control device 99, and the air conditioning system control device 103.

When this data input item list is applied, the display contents of the control gain characteristic screen 21G are also changed, and the engine characteristic, the shift characteristic of the automatic transmission, the brake characteristic, the TCS control characteristic of the traction control, and the antilock function are set. It is assumed that the ABS characteristic of the brake control, the power steering characteristic, the rear wheel steering characteristic, the air conditioning characteristic, and the like are displayed in a graph. Then, the data input item list of FIG. 10 and the control gain characteristic screen of FIG.
The data input item list and the control gain characteristic screen corresponding thereto may be selectively utilized.

3] Since the gain changing device 20 is configured to be able to transmit data to the gain changing device 70, it is not necessary to give the gain changing device 70 the same function as the gain changing device 20. , A part of the SW and keys in the gain changing device 70 (keyboard 89, A
VSW76, air conditioning SW77, clock SW78, gain change SW75, etc.) may be omitted.

4] In the method of inputting data of the control gain coefficient allowable range from the gain changing setter 65 to regulate the lower limit value and the upper limit value of the control gain coefficient, each part control is performed based on the purpose of use of the automobile. Set the lower and upper limits of the control gain coefficient of the device, and also set the lower and upper limits of the control gain coefficient of each control device based on the driving history of the owner driver. It is also possible to adopt a method of setting the lower limit value and the upper limit value of the control gain coefficient of each part control device in consideration of the desired characteristics of the owner driver in addition to the driving history and the driving skill.

5] In place of the method of inputting the data of the control gain coefficient allowable range from the gain changing setter 65 and regulating the lower limit value and the upper limit value of the control gain coefficient, the driving history and the driving skill of the owner driver are replaced. In consideration of the above, the correction coefficient αe, α for correcting the control gain coefficient of each part control device
Input a, αw, αp to the gain changer 20 and multiply the correction component of the control gain coefficient (FKe, FKa, FKw, FKp) set in the made-to-order mode or the system mode by the correction coefficient α. Determine the control gain coefficient (FKe, FKa, FKw, FKp) with.

That is, when the control gain coefficient FKe is described as an example, it is set as in the following equation. Control gain coefficient FKe = 1.0 + (FKe −1.0) × αe Furthermore, a specialist of a specific business entity can also adjust the correction coefficient of these drivers based on the driving history and driving skill of drivers other than the owner driver. It is also possible to correct the control characteristics set for these drivers in the one-touch SW mode by setting the input to 20 and using the correction coefficient.

6] In place of the method of inputting the data of the control gain coefficient allowable range from the gain changing setter 65 to regulate the lower limit value and the upper limit value of the control gain coefficient, a relatively large control in a specific business entity is performed. In order to set the gain coefficient, the final control gain coefficient FKi (where i = e, a,
w, p) is set as in the following equation. FKi = 1.0 + (Ki-1.0) × 3 × a1 × a2 × a3 × a4 × a5 × β ×
γ In the above equation, a1 to a5 are control gain correction coefficients shown in Table 1, β is a coefficient shown in the map of FIG. 52, and γ is FIG.
Are the coefficients shown in the map.

Here, although various information described in the data input item list is added to the coefficients a1 to a5 and Ki as described above, the driving skill and personality of each owner driver should be sufficiently added. It has not been. Therefore, a specialist of a specific business entity rides on the test drive of the owner driver for several hours, ranks the driving skill of the driver into five stages of A to E, and applies the rank to the map of FIG. 52. Based on the test driving and the listening information from the owner driver, the personality of the driver is ranked in five stages of A1 to E1,
The rank is applied to the map of FIG. 53 to determine the coefficient γ. Since it is desirable to greatly modify the coefficient β according to the improvement of the driving skill of the owner driver,
It is desirable to change the coefficient β based on a predetermined arithmetic expression or a map every predetermined period or every predetermined traveling distance of the owner driver (for example, 5000 km).

In the lowest rank E, the driver's driving skill is β = 1/3, and in the highest rank A, β = 1.0.
That is, the correction component of the final control gain coefficient is increased as the driver has a higher driving skill. Also,
The rank E1 in which the driver's personality (not only the normal personality but also emotional emotions and emotions due to physiological factors) is the most unstable is γ = 1/3, and the most stable rank A1 is γ = It is 1.0. That is, the more stable the driver, the larger the correction component of the final control gain coefficient. The gain changing setting device 65 is connected to the access port of the control device 60 by the specialist and the coefficients β and γ are input and stored in the memory of the RAM 62.

Further, the one-touch SW screen 21I of the gain changer 20 is provided with a primary characteristic SW for selecting the control gain coefficient (this is the primary control characteristic) determined by the above equation. The primary control characteristic SW is used to select the primary control characteristic so that the control gain of each control device (EGI, ACS, 4WS, ACS) can be changed. Therefore, if the owner driver wants to greatly change the control gain,
When it is desired to select the primary control characteristic with the primary characteristic SW and to change the control gain to a comparatively small value, the custom-made control characteristic can be selected with the custom-made characteristic SW. still,
The coefficients β and γ can be input and stored by connecting the gain changing setting device 65 to the access port of the control device 90 of the gain changing device 70. In this way, the primary control characteristic is corrected by the coefficient β that takes into account the driving skill of the owner driver and the coefficient γ that takes into account the character, so the change range of the control gain can be changed without impairing the steering stability. It can be set large.

7] The gain changer 20 can be provided with a key corresponding to the data input item in the data input item list, in which case the data input is simplified. However, it is desirable to provide a numeric key or a character key for inputting a title and the like. As the gain changer 20, various modes can be adopted, but it is required to have a display function, a data input function, an arithmetic processing function, a data storage function, a wireless transmission / reception function, and the like. Good luck
Not only the TV receiver but also a personal computer or the like may be connectable.

8] The one-touch SW illustrated on the one-touch SW screen is merely an example, and one-touch SW corresponding to the type of road such as an urban area where a car runs, an outlying area, a mountain road, a low μ road, a snow road, etc. SW, one-touch SW corresponding to various purposes of use and use time zones, one-touch SW corresponding to a driving driver, and the like can be appropriately provided. In addition, a plurality of one-touch SW, (a) a specific operating state (starting, starting inspection, parking, refueling, tunnel,
(Visibility improvement, rainy weather, etc.), (b) Types of roads to be traveled (congestion, highways, general roads, urban areas, suburbs, mountain roads, low μ roads, snow roads, etc.), (c) Driving Drivers (owner driver, wife, son, daughter, etc.), etc., and one SW is provided for each group (a) to (c),
The SW name may be cyclically displayed on the display each time the SW is operated. For example, in the (a) group, each time the a group SW is operated, the start,
It is configured to display cyclically in the order of start inspection, parking, refueling, tunnel, visibility improvement, rainy day, and so on.

9] The one-touch SW does not necessarily have to be configured by the screen SW of the display, but may be configured by the gain changer 20 and / or a plurality of SWs attached to the instrument panel of the automobile. Further, among the one-touch SWs, the start SW, the start inspection SW, the parking SW, the refueling SW, the tunnel SW, the visibility improving SW, the device setting SW such as the rainy SW,
It is also possible for a professional to set the operation mode of the operation target device in each of these SW modes based on the wishes of the owner driver.

10] In the above embodiment, the entire system of the control devices (EGI, ACS, 4WS, P / S) of each part is configured to select the manufacturer characteristic, the primary characteristic, and the made-to-order characteristic. You may comprise so that a manufacturer characteristic, a primary characteristic, and a bespoke characteristic may be selected for every control device. In this case, after designating the respective control units by a predetermined command signal, the one-touch SW may be used to select the manufacturer characteristic, the primary characteristic, and the made-to-order characteristic.

11] In the above-mentioned embodiment, the custom-made characteristic is not constituted so as to change the control gain characteristic of EAT, but EGI, ACS, 4WS, P / S
The control gain characteristic of EAT may be changed similarly to the control gain characteristic of. 12] In the above embodiment, the control gain characteristics of the ABS control device controlling the anti-lock braking device and the TCS control device controlling the traction control device are not specially set, but these control gains are not set. The characteristics may be set in the same manner as the control gain characteristics of the respective control devices 14 to 18.
Furthermore, the longitudinal position, height position, and seat position of the vehicle seat device,
It is also possible to provide a seat adjusting device capable of automatically adjusting the inclination of the seat back, etc., and to adjust the seat device according to the setting of each driver via the one-touch SW.

13] In the above embodiment, the gain changer 2
In 0, the control characteristic is calculated by using the input data and the control characteristic data is transmitted and output together with the input data in the order-made mode, but only the input data is transmitted and output, and the gain changing device The control characteristic may be calculated based on the input data. However, even in the gain changer 20,
It is desirable to execute the calculation of the control characteristic in order to display the control characteristic. 14] Various modifications may be added to the control gain changing system of the present invention based on existing techniques and techniques obvious to those skilled in the art without departing from the technical idea of the present invention.
