Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an automobile, and more particularly to a control device capable of changing a control characteristic by a driver.

[0002]

2. Description of the Related Art Conventionally, for example, in an automatic transmission control device for an automobile, a shift control is performed according to a preset shift diagram. See JP-A-61-274155. The shift diagram is set in several modes and can be used by switching between them. However, these shift diagrams are written in advance in a memory in the control device. For this reason, the driver's intention cannot be reflected on the driving characteristics.

[0003]

Conventionally, it was possible to select one of the preset shift modes, but the number of selectable modes was small and unsatisfactory. For example, even if you select one mode,
Due to individual differences in driving manners, differences in road conditions, and the like, the pattern of the shift diagram set as the mode is not always satisfactory to the driver.

In addition to the shift control, it is desirable that, for example, the assist amount of the power steering reflects the driver's intention. Conventionally, such as a motorized mirror and a seat, which are not controlled during driving and are completely unrelated to other controls, can be adjusted.

However, it has been difficult to reflect the driver's will on the characteristics of engine control and vehicle operation control.

An object of the present invention is to provide a control device capable of changing a set value or an operation characteristic by a driver, and to provide a control device having a backup function even when the control device is abnormal. The aim is to ensure drivability and safety that reflect the will of the driver. Another object of the present invention is to provide a device that can easily perform data setting for each driver.

[0007]

In order to achieve the above object, the present invention has a rewritable storage means for storing characteristic data including a set value in the storage means so that the storage can be rewritten by a driver's instruction. It was made. Furthermore, the storage area of the storage means is divided for each driver, and the storage area corresponding to the driver can be selected by the driver identification means. The diagnosis means for diagnosing the control means and the backup means in the event of an abnormality are provided to the backup means. It is configured to be switched.

[0008] In addition, the characteristic data storage means for each driver is separated from the control device and mounted when necessary, whereby the data setting for each driver can be easily performed.

The rewritable storage means is, for example, an EEPROM.
This is storage means that uses a power-backed RAM, NVRAM, or magnetic memory as a storage medium, and can store data that defines the operation state and operation characteristics of the control means.

The control means controls the control target based on data stored in the storage means, sensor signals from sensors or a control state monitor signal for monitoring the control state of the control target as required. Control signal can be output.

The input means by the driver includes, for example, a keyboard, a switch, an operation lever, and the like. With this input means, the driver's favorite set values, control characteristics, and the like can be input as necessary.

The rewriting of the memory is performed based on a setting / change instruction signal from the input means.
The stored contents can be rewritten based on the control state monitor signal or the current stored contents stored in the storage means.

The driver identification means identifies the driver and selects a storage area corresponding to the driver according to the result. For example, the driver may input or select his / her own registration number by using a keyboard or a switch, or the storage means may be separated from the device and made portable so that the driver can use his / her own storage means. By owning and attaching the storage means to the device, the driver can be automatically identified and the data to be used can be automatically selected. By this means, setting of favorite data for each driver can be easily performed.

The diagnosis means diagnoses whether or not the driver identification means, the rewritable storage means, etc., can operate properly. If the operation cannot be performed properly, the data used by the control means is stored in another storage device set in advance. Switch to read from the means. Thereby, stability at the time of device failure can be enhanced.

The display means indicates whether or not the memory can be rewritten based on the driver's intention (for example, a result of checking whether the rewriting is out of the allowable rewriting range), whether or not the rewriting has been correctly completed, or And whether or not a failure has occurred based on the diagnostic result by the diagnostic means, etc., thereby improving operability and safety.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment will be described below with reference to the drawings.

FIG. 2 is an external view showing a part of the driver's seat.
The front display units 22 and 24 display vehicle speed and engine speed, the display units 26 and 28 display cooling water temperature and gasoline remaining amount, and the display unit 30 displays instructions and alarms. These constitute a display unit 110, which displays the operating state of the engine and the instruction / alarm, the operating state of the power steering and the instruction / alarm, the state of the transmission, and the indication / alarm. The status of the vehicle and warnings can also be displayed on the front. That is, the display unit displays necessary information for the operation of the engine, the powertrain system, the vehicle body, and the like.

On the right side, a card reader 32 constituting the card unit 116, operation keys 34, and a display unit 36 are provided. A card that holds personal data such as personal desired characteristic data and a personal encryption is inserted into the card reader, and these data are read and written. The system can be started up by operating not only the key switch but also the card unit, and the car can be moved without using the key switch by operating the card unit as described later.

On the left side, an operation key 42, a display section 44, and an external communication device 46 such as a telephone are provided. The system is connected to an external organization via the communication device 46. This makes it possible to diagnose the system based on an instruction from an external organization, to input data from the external organization, for example, to input navigation data, and to transmit data from the system to the external organization. This makes it possible to diagnose a vehicle using an external engine and various instructions accompanying the instruction, instructions regarding road information, automatic payment of an expressway, and the like.

The disk drive 48 constitutes a disk unit 114, which not only allows storage of necessary data, but also enables input and output of a program of a control unit open to individuals in this system. It is also used for writing a data communication program with an external institution via a communication unit, holding data based on the communication, and reading a sales program created in a software house.

At the center of the handle 58, there are provided a display unit 50 constituting an operation unit 118 for operating the system, operation switches 52 and 54, and an input unit 56 such as a key switch. Each unit constituting the system can be operated by its own input means, but after the system has started up, each unit can be controlled via this operation unit separately from the input means of each unit. In addition, each unit can be organically connected via a communication unit to have various new functions. In addition, operation by connection with an external engine becomes possible.

The start-up of the system itself will be described later.
The starting can be performed by two methods, starting by a key switch and starting by operating a card unit. There are also multiple types of systems, and R
There are systems based on OM programs and systems based on disk drives. If a system that has already started up is restarted with another type of system, only the operation unit can be used without the key switch or card unit operation described above. Can be restarted.

In FIG. 2, a select lever 60 constituting a transmission unit is provided on the left side of the driver's seat. By operating this lever, automatic shifting and parking can be performed. Although not shown, a television, a radio, a telephone and other units are provided.

FIG. 3 is a block diagram of the system. The engine control unit 102, transmission unit 104, air conditioner unit 106, power steering unit 108, display unit 110, communication unit 112, disk unit 114, card unit 116, and other units 12
0, the operation unit 120 is an optical transmission line 124
And an electric transmission line 126. Further, power is supplied from a battery to each line via a power supply line. Engine control unit 102, transmission unit 10
4. Air conditioner unit 106, power steering unit 108
Are closely connected and are interconnected separately from the transmission lines 124 and 126. This is shown as line 128 for the time being. However, these are not multiplex transmissions but are connected by dedicated lines.

FIG. 4 is a diagram for explaining the operation mode of the system. Each of the control units in FIG. 3 partially receives data from other units, but operates in principle independently for each unit. In addition, diagnosis is performed as a system. In principle, self-diagnosis is performed for each unit, and switching to backup means is performed as necessary. The backup means is provided for each unit.

(A) shows the operation of the operation unit. When the key switch or card unit is operated in the stopped state, the system starts up and enters the operation mode. A start command A is issued to another unit in the operation mode, but when the system does not start, the other unit can be started (operated) by operating a key switch. At this time, it is also possible to switch to the backup means as abnormal and issue a start-up command A by the backup means. When the operation is completed, a stop command B is issued by operating the key switch or a command from the driver to the operation unit. Even when the system is abnormal, the necessary control unit operates by operating the key switch, and the vehicle can be moved.

FIG. 4B shows an operation mode of the engine control unit. This unit shifts from the stop mode to the standby mode by the command A. That is, the system is started up by the card unit, and by issuing a start-up command from the system, power is supplied to the engine control unit, and the system enters the standby mode. In this mode, the control unit itself is already in an operating state, but is in a state without an engine start command. The control unit starts the engine in response to the engine start command,
Move to engine operation mode. During the start of the engine, a signal C indicating that the engine is being started is output, while the signal D is being output during operation.

The engine is stopped by receiving a command signal B from the system. However, the operation to each mode can be promoted by a key switch separately from the instruction from the system. This is to provide a backup when the system is abnormal, but to allow the elderly or women to easily drive when they want to drive. When the key switch is turned off, the main power of the engine control unit is turned off, the unit is stopped, and the engine is stopped.

As shown in FIG. 4C, the transmission unit is started up by the signal A from the operation unit, that is, by operating the card unit, and changes from the stop mode to the standby mode. This mode, self-diagnosis, and the like are performed, and the operation mode is set when the operation is completed. Therefore, operation is possible even before the engine enters the start mode. The vehicle stops at a signal B indicating a stop instruction from the driver. If it breaks down, it goes into backup mode. Like the engine control unit and other units, the key switch alone can be operated or stopped, and these are shown as A and B.

FIG. 4D shows the operation of the automatic air conditioner unit. Fig. 4 shows the transition from the stop state to the standby mode.
The process moves under the condition A of (a). In the standby state, display is possible, and temperature setting is also possible. However, the operation of the automatic air conditioner is started under a condition C indicating that the engine is running.

The operation stops at the point where the operation shifts to the backup means due to the failure and at the condition B.

FIG. 4E shows the operation mode of the display unit. The unit is in a stand-by state while the car is stopped, that is, parked. In this state, a minimum display such as a clock is displayed. When a display command is input from an operation unit or the like, a display operation is performed in response thereto.

In the condition C where the engine is in the start mode, the mode becomes the mode 1 for display check. Here, it is checked whether or not display is disabled. Next, the mode shifts to mode 2 under condition D indicating that the engine is running. When a failure occurs, the operation is shifted to the backup means. That is, when it cannot be displayed on the front, it is displayed on the display surface of the operation unit. The process returns to the standby mode under the condition B.

FIG. 4F shows the communication unit, which is in the standby mode when the vehicle is parked and the engine control unit is stopped. In this state, since the need for in-vehicle transmission is low, the electric transmission line that consumes less power is activated, and the optical transmission line is stopped. Next, the operation state is set based on the condition A. That is, transmission via the optical transmission line is performed. In the event of an abnormality, a backup operation is performed.

FIG. 4G shows the operation of the card unit and the disk unit. When the power switch is turned on, the apparatus enters a standby state, and shifts to an operating state by self-diagnosis. However, when the engine is started, the power supply voltage is reduced, so that when the engine is started, a standby state in which the reading and writing operations are not performed.

FIG. 5 is a flowchart showing system startup. System startup is divided into two parts. One is to start up from the stop state of the system and is called a cold start. The other is to change a system that has already been started up to another system, which is called a hot start.

The cold start includes a start 502 by a key switch and a start 504 by a card. Use of a key switch to prevent theft of a car or input of a card code is a condition for startup. Although details of step 504 will be described later, if it is confirmed that the encryption input is correct, the process proceeds to step 508 even if there is no key switch.

In the hot start, when there is a system change instruction, the process proceeds to step 508 in step 506.
However, step 506 is executed on the condition that the vehicle is stopped, that is, the engine is idle or the select lever 60 is at the parking position.

At steps 508 and 510, an abnormality of the communication unit or the disk unit is diagnosed. When an error occurs in the communication unit, a backup is determined according to the content of the error. For example, in the event of a failure of an internal optical transmission line, it operates with reduced capacity using an electrical transmission line. If the communication line with the outside is abnormal, the internal transmission operates normally. When neither the optical transmission line nor the electric transmission line can be used, the system does not start. At this time, each unit operates independently by operating the key switch.

When the disk is abnormal, the disk is not used and starts up in the system using the internal memory. At this time, step 514
Use to display the disk error.

At step 516, it is determined whether to start up in the system stored in the disk or in the internal memory. When the power of the disk is turned off or the system floppy is not set in the disk, the system starts up in step 520 with the system stored in the internal memory. On the other hand, when the system is set on the disk, the disk is read in step 518, and the system starts up with the system program held on the disk. This makes it easy to improve the system, and enables the creation of a system even in a software house.

At step 520, the signal A of FIG. 4 is transmitted to each unit. In addition, each unit receives a model report and a diagnosis report. At step 522, it is determined whether or not the unit is normal. If the unit is normal, the process proceeds to step 524. If it is abnormal, the process proceeds to step 526.

FIG. 6 is a display surface table used in the use determining steps 524 and 526, and the driver determines the specifications. For example, change the engine characteristics to one that suits you,
When using this, put 2 in the parentheses of the characteristic. The same applies to the transmission. In the case of an air conditioner or a disk unit, indicate whether to use or not. In addition, depending on the model, when the characteristic is only standard and is not open to the individual, it is forcibly set to 1 and cannot be changed. Lastly, if you want to give priority to the results of the system specification determination from the beginning, the parentheses in item 10
Insert The result is set on the card, the result already selected is displayed in parentheses from the beginning, and the operation is completed only by operating the execution key. Step 5 when the unit is abnormal
Abnormality is displayed on the abnormal unit on the screen of FIG. 6 displayed at 26, and the use of that unit is forcibly determined. For example, when the air conditioner unit is abnormal, the non-use is forcibly selected.

When the specifications of steps 524 and 526 are determined, they are transmitted to each unit, and the start-up of the system is completed.

Steps 524 and 526 for danger prevention
Indicates that the engine is idle or the select lever 60 is in a parking condition, but the menu display step 530 after the system is started up is also the idling operation or the select lever 6
0 is only when parking. The menu disappears as soon as the car is running. When the specification is to be changed, steps 524 and 526 are executed again according to the instruction.

In the above-described apparatus configuration, an operation unit including a button and a lever shown in FIG. 8 is further provided at, for example, a steering central portion 56 shown in FIG. 2 to change the shift pattern of the automatic transmission according to the driver's will. It is designed to be easily rewritten (changeable).

FIG. 9 shows the configuration of the automatic transmission control system (the transmission unit 104 in FIG. 3) of the present embodiment.
SP) and the throttle angle signal (θ _TH ) from the throttle sensor 203 in accordance with a shift diagram as shown by a characteristic 220a in FIG.
This is executed by controlling a combination of ON and OFF operations of the shift solenoid 211 and the shift solenoid B212. Other inputs to the control device 210 include signals from a shift point selection button 207, a change amount setting lever 204, a determination input button 205, a traveling mode selection button 206, and the like shown in FIG. The change operation is stopped by a signal from the RESET button. Further, the control device 210 includes an A / D converter 208 for taking in an analog amount such as the throttle sensor 203. Arithmetic unit 209
Uses a microprocessor, and the memories connected thereto include a ROM 213 built in the control device 210 and an IC card memory 201 connected via a card reader 32 as shown in FIG. Note that a RAM used when the arithmetic unit 209 executes arithmetic processing is not particularly shown, but is built in the arithmetic unit 209. Further, a display device 50 is also connected so that various displays can be made.

The program and data for the shift control are as follows.
Although the data is stored in the ROM 213, only the data portion or a part thereof is provided with a data area in the IC card memory 201, and when the IC card memory is normally connected and can operate normally, the IC The program is configured so that the card memory side is selected and used.
FIG. 14 shows the switching operation of the memory between the ROM and the IC card memory. The IC card memory 20
NVRAM is used for one memory element. NVR
AM is a non-volatile RAM, and is a RAM in which the contents are stored even when the power is turned off.

Next, referring to FIGS. 10 and 11, a description will be given of a method of changing the shift pattern when stopping. In this case, the operation procedure of the device viewed from the driver side is as shown in FIG. 11, and the processing procedure viewed from the control device side is as shown in FIG. This will be described below.

First, in step 301, it is confirmed whether or not the driver has a will to change. This is determined based on whether any one of the shift point selection buttons 207 has been pressed. If this button is not pressed, there is no change intention and the data is not rewritten. This is a signal for starting the change. The change start may be input from a dedicated switch. If at least one button has been pressed, it is determined that there is a will to change, and the procedure proceeds to step 302 and subsequent steps.
If the subsequent operations are not executed within the predetermined time even if the shift point selection button is pressed, the intention to change is canceled in step 303 and the process ends. In step 304, the contents of change are input. This is for inputting the travel mode, shift point, and change amount set by the buttons and levers shown in FIG. In this case, the change amount set by the change amount setting lever 204 is determined by pressing the shift point selection button 207 and the traveling mode selection button 206 which are pressed at the time when the finalization input button (SET button) 205 is pressed.
As a set of data.

Next, in step 305, it is checked whether or not the input change amount is within the allowable range. If the change is out of the range, the change is displayed on the display device 50 in step 306, and the driver is re-inputted. Prompt. This is performed in order to allow the driver to make a drastic change and prevent the safety and the drivability from being impaired. Next, when the input value is within the allowable range, the shift pattern (shift diagram) is changed in step 307.
In this case, the position of the change amount setting lever 204 is “lowered”.
If it is on the side, the vehicle speed at the shift point (shift-up point) for the same throttle opening is changed to a lower speed side, and if it is on the "increase" side, it is changed to a higher speed side. In this embodiment,
Although only the shift-up side can be changed, the shift-down side can also be changed by providing shift-up / shift-down selecting means.

FIG. 13 shows a specific example of the pattern change in step 307. In both cases, the change amount setting lever is set to the “lower” side, and 220 b
The one that has been translated with respect to the original pattern, 220c has the change amount proportional to the throttle opening θ _TH ,
Reference numeral 220d designates a portion in which the amount of change is maximized at a certain throttle opening. Other ways of changing the pattern are also possible.

Next, in step 308, the changed shift pattern is set as the shift pattern of the designated mode,
Write to the shift pattern data area on the card memory. Step 309 indicates that all the above change procedures have been completed.
The information is displayed on the display device 50 to inform the driver.

The above procedures 301 to 309 are all performed in ROM2
13 programmed. In the ROM 213, a procedure 310 of the shift control program is also programmed. In this procedure 310, the shift control is performed based on the shift pattern data written in the IC card memory in the step 308.

However, as already described in the description of FIG. 14, when the IC card memory 201 does not operate normally, the shift control is performed with reference to the initial data set in the ROM 213 in advance. The data change procedure from 301 to 309 is not performed. At this time, the display device 50 also indicates that fact.

Next, a method of changing the shift pattern during traveling will be described with reference to FIG.

Steps 330, 331 and 332 are the same as steps 301, 302 and 303 in FIG. Step 333
Then, the shift point selection button is checked, and if the (1 → 2) button is pressed, the procedure from step 334 is executed, and if not, the procedure shifts to steps 343 and 345.
4 and subsequent steps 346 and subsequent steps, steps 334 to 34
The description is omitted because it is the same as that described above.

In step 334, the shift operation is prohibited and the range 1 is fixed. Acceleration is performed in this state. Thereafter, the vehicle speed data (VSP) and the throttle opening data (θ _TH ) shown in step 335 are always taken in a predetermined cycle. At this time, if the vehicle speed reaches the upper limit allowed for the throttle opening at that time in the shift range 1 before the confirmation input button is pressed, the upper limit value is set to a set value for safety, and the shift pattern is changed. Rewriting, and further permitting a shift operation, and shifting up to range 2. This procedure is shown in steps 336, 337, and 34.
1,342.

If the confirmation input button is pressed before the vehicle speed reaches the upper limit, the lower limit is checked in the same manner.

If the vehicle speed at the time when the confirmation input button is pressed is within the range of the upper and lower limits with respect to the throttle sensor opening at that time, the shift is performed in step 341 using the vehicle speed data and the throttle opening data. The pattern is written to the IC card memory. That is, rewriting is performed on a shift diagram that passes through a point determined by the vehicle speed and the throttle opening. In this case, several rewriting methods as shown in FIG. 13 are possible.

By the method described above, the shift pattern of the automatic transmission can be changed to a characteristic suitable for the driver's preference. In this embodiment, since the IC card memory is used as the rewritable storage means, each driver owns this IC card one by one, and the card is automatically set by setting the card in the card reader during driving. In another embodiment, a large-capacity memory (e.g., a hard disk device) built into the device is used as rewritable storage means, and a driver ID No. It is also possible to identify the driver by entering. And thereby change the data storage area.

In this embodiment, an example of an automatic transmission control device is shown. However, it is possible to easily set a driver's favorite characteristic in any other control device in the same way. Become.

FIG. 1 is a functional block diagram showing one embodiment. When the driver identification code is input from the input means 1, it is confirmed by the identification means 3 and the storage rewriting means 8 having the first storage means.
Send an identification signal to The first storage means holds characteristic data. The match with the driver identification display in the first storage means is checked, and if not, the mismatch is displayed on the display means 9. The driver's display and stored data in the first storage means can be changed by an operation from the input means 7. Memory rewriting means 8
The data read from the first storage means by the selection means 4
To the control means 5, and controls the control target 6 with the control characteristics based on this data. The control means 5 uses output signals of the sensor 11 and the monitor means 12 for control as needed. The operation of the memory rewriting means 8 is inspected by the diagnosis means 10, and when abnormal, the selection means selects the second storage means, and the control means 5 controls the control target 6 with the read data. The display of the abnormality is performed by the display means 9. The control target includes an automatic transmission, power assist means for power steering, engine control, and the like. In this case, the data from the first or second storage means are the up-shift and down-shift conditions of the transmission, the assisting force of the power steering, and the fuel supply characteristics during acceleration / deceleration of the engine control, respectively.

The functional block diagram of FIG. 1 can be realized by a computer program. FIG. 14 is a flowchart of the operation of the selection unit 4 and the diagnosis unit 10.

First, an IC card as the first storage means is preferentially selected at step 350. Next, step 351
To check reading and writing of the IC card. At step 352, it is determined whether or not it is normal. If abnormal, standard characteristic data, which is the second storage means, is selected in step 353.

FIG. 15 shows a flow when reading data stored in an individual memory by a reader (reading device). In step 801, it is checked whether the memory read operation by the reader has been performed a specified number of times.
Step 80 if the prescribed circuit read operation has been completed.
In step 9, the reader or memory determines that an error has occurred, and notifies the error by the notification means. If the number of memory read operations has not reached the specified number, the process proceeds from step 801 to step 802 to perform the memory read operation. Put the read data into the buffer memory. In step 803, the contents of the buffer memory read and the contents read from the memory are compared again. If the two are equal, the process returns to step 804. If they are not equal, the process returns to step 801 as a read error.

In step 804, the control data selected from the menu is selected in the reader ( _DS1 to _DS1 ).
D _Sn ). In step 810, the reader or memory to generate the data to be initial value of the control data when an error occurs (D _S1 ~D _Sn). In step 805, the an initial value of the control data D _S1 to D _Sn, is transmitted to each controller C ₁ -C _n. In step 806, the data each controller C ₁ -C _n is received is read by the reader. In step 507, it is checked whether or not the data transmission operations in steps 805 and 806 have been executed a specified number of times. In step 808, D _S1 to
If it is confirmed that D _Sn and D _{R1 to} D _Rn are the same value,
The data reading from the memory and the transmission are terminated. In step 811, the controller C _i that _satisfies D _Si ≠ D _Ri and its transmission system are specified, classified into CEs, and the error is stored and displayed.

FIG. 16 shows a flow when the control data selected by the driver and the control data self-corrected while the vehicle is running are stored in the memory. Step 90
At step 1, it is determined when the ignition key is turned off. At step 902, it is checked whether the memory is protected. If it is not protected, the final control amount data of each controller is stored in step 903.
No control amount data is stored from the controller and its system determined to be an error in 1. Step 90
In step 4, the power supply of the reader for writing and reading the contents of the memory is turned off, and the process ends.

FIG. 17 is an external view showing a part of the driver's seat. On the front, there are instruments 704 for displaying the state of the vehicle such as the vehicle speed and the number of engine revolutions and various kinds of warnings, and a card unit 701 is provided on the right side thereof. In addition, a memory unit 702 and an operation unit 703 at the center of the handle are provided.

In addition to a plurality of personal information, initial values which are standard setting values of each specification are also stored in the memory unit, and can be transmitted to each unit when a system abnormality occurs or when necessary. Changes after setting personal information or initial values in each unit, such as while driving a car, are performed by inputting to the operation unit. When the ignition key is turned off, personal information is stored in the memory unit except when initial values are set for all units.

FIG. 19 shows a process performed when an abnormality is detected during system startup. When the ignition key is turned on, the card unit starts the control in step 720 and proceeds to step 7
At 22, a self-diagnosis is performed, and when an abnormality is detected, a card unit abnormality is displayed on the operation unit display section, a personal memory system warning light in the instruments 704 is turned on, and an alarm sound is emitted at the same time. After that, the operation unit display unit displays in step 723 that each specification is set to the initial setting.

If the card unit is normal, step 72
It is checked in step 4 if a card is inserted, and if not inserted, in step 726 it is indicated in step 728 on the card unit display unit and the operation unit display unit whether initial settings are acceptable for each specification. Here, when the driver inputs to the card unit or the operation unit to select the initial setting and when the ignition key is set to the START position, the specifications of each unit are set to the initial setting. If the user inputs an instruction to select personal information setting to the card unit or the operation unit, an instruction to insert a personal card is issued in step 727.

When the personal card is inserted, the personal number stored on the card is read in step 730,
It is determined in step 732 whether the data has been read correctly. If it cannot be read correctly and there is no personal information corresponding to the read personal number, step 73
In step 4, an alarm sound is generated at the same time as displaying on the display unit of the card unit and the operation unit that the personal card is invalid. Then, in step 736, it is displayed that each specification is set to the initial setting. Let it.

If it is determined that the card is valid, step 7
At 40, personal information is transmitted to each unit.

The system startup is completed when personal information or initial values are transmitted to each unit.

At the start of the system, when an input of a specification change is made from the operation unit, it is determined whether or not the input value is within the specification limit range. Is displayed and an alarm sounds. The specification setting retains the value before the change value was input.

According to the present embodiment, when an abnormality is detected in the system, each specification is set to a standard value required for operation, and operation is enabled. By issuing an alarm, it is possible to urge the driver to perform maintenance of an abnormal location. In addition, setting can be changed for each specification by inputting from the operation unit, so that it can be adjusted to the driver's orientation.

According to this embodiment, when an abnormality is detected in the system, each specification is set to a standard value required for operation,
Enable driving. In addition, since the driver can be notified of the fact that there is an abnormality by issuing an alarm, the necessity of maintenance can be prompted.

[0079]
