Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention belongs to the technical field of industrial vehicles.

[0002]

2. Description of the Related Art Generally, a forklift is a vehicle characteristic that affects response characteristics to an operation amount and an operation speed of a lever or the like, such as speed limit, traveling power, accelerator level, cargo handling lift speed, tilt speed, cargo handling power. Can be set, and each operator usually sets a vehicle characteristic that suits his / her preference and uses the vehicle.

[0003]

However, when a plurality of operators use a single forklift, each operator sets vehicle characteristics according to his or her own preference. For example, operator A
Operator B after setting and using vehicle characteristics (A)
When the vehicle is used, the vehicle characteristic (B) is set again. That is, each operator needs to reset the vehicle characteristics each time it is used. Such a problem is not limited to forklifts, but is a problem common to industrial vehicles whose vehicle characteristics can be set.

[0004]

Means for Solving the Problems and Effects of the Invention An industrial vehicle according to claim 1 for solving the above problems comprises an input means for inputting data and the like, and an input operation via the input means. In an industrial vehicle including vehicle control means for controlling vehicle operation based on set vehicle characteristics, a password storage means for storing a password set by an input operation via the input means, and the input means Vehicle characteristic storage means for linking and storing the vehicle characteristic set in correspondence with the password by an input operation via the password, and when the password is input via the input means, The determined password matches any of the passwords stored in the password storage means,
Operation permitting means for permitting the operation of the industrial vehicle on the condition that the two coincide with each other, and when the operation is permitted by the operation permitting means, the industrial vehicle is based on the vehicle characteristic linked to the entered password. And the vehicle control means for controlling the operation of.

In this industrial vehicle, when the password is set by the input operation through the input means (for example, key switch, ten-key panel, etc.), the password is stored in the password storage means. Since this storage must be maintained even when the main switch of the industrial vehicle is off, it is desirable to use a non-volatile storage element such as an EEPROM. Note that the configuration may be such that the storage is maintained by a backup power source or the like.

When the vehicle characteristic is set in association with the password by the input operation through the input means, the vehicle characteristic storage means stores the vehicle characteristic in association with the password. Similarly to the password storage means, the vehicle characteristic storage means is required to be able to maintain the storage even when the main switch is off. The individual storage elements (for example, EEPROM) can also be used as the vehicle characteristic storage means and the password storage means.

After the password is set once, when the password is entered through the input means, the operation permitting means determines whether the entered password matches any one of the passwords stored in the password storing means. Then, the industrial vehicle is allowed to operate on the condition that the agreement has been made. Note that the password may be matched as an essential condition because the operation may be permitted when the AND condition with some other condition is satisfied.

The vehicle control means, when the operation is permitted by the operation permission means, controls the operation of the industrial vehicle based on the vehicle characteristic linked to the inputted password. In this way, first, a password for identifying the operator is set, and then the vehicle characteristics are set corresponding to each password and linked with the password and stored. When a password is entered when operating the industrial vehicle, the operation permission means collates the password to permit the operation of the industrial vehicle, and the vehicle control means determines the industrial vehicle based on the vehicle characteristic linked to the entered password. Control movements. Therefore, when a plurality of operators use one industrial vehicle, if vehicle characteristics are set according to their passwords and their own preferences, there is no need to reset the vehicle characteristics each time they are used.

An industrial vehicle according to a second aspect is the industrial vehicle according to the first aspect, further comprising password reading means for obtaining the password from a portable storage medium storing the password, and the operation permitting means, It is determined whether or not the password acquired by the password reading means matches any of the passwords stored in the password storage means, and permitting the operation of the industrial vehicle on the condition that the password is matched. And

Examples of the portable storage medium include a magnetic card, an IC card having a communication function such as radio, and an equivalent remote control device. The password reading means is a reading device or the like corresponding to such a portable storage medium. According to this structure, the operator does not need to operate the input means to input the password.

By the way, depending on the usage pattern of the industrial vehicle, it may be inconvenient to decide whether or not the industrial vehicle can be operated by the password. In that case, as described in claim 3, a password use presence / absence setting means for setting whether or not to use the password is provided, and when the password is not used, the operation permission means permits the operation. It suffices to adopt a configuration that enables operation without the need.

Also, each operator (use of the vehicle)
Since it can be identified by a password, it can be used for vehicle management and work management. A preferred configuration therefor is the configuration of claim 4. An industrial vehicle according to a fourth aspect is the industrial vehicle according to any one of the first to third aspects, in which clocking means for measuring the current time and vehicle data generated or changed with the operation of the industrial vehicle are acquired. Since the timekeeping means includes a data creating means for creating management data associated with the time counted by the timekeeping means and the password, and a data storing means for storing the created management data, management is performed for each password, that is, for each operator. Can create and store data.

This management data is displayed on, for example, the display device according to claim 5, or is output to an external device (for example, a personal computer) by the external output means according to claim 8 to be displayed or printed on the display. be able to. This makes it extremely easy to manage for each operator, such as who uses how many vehicles.

An industrial vehicle according to a fifth aspect is the industrial vehicle according to any one of the first to fourth aspects, wherein the industrial vehicle is equipped with a display device for displaying information regarding an operating state of the industrial vehicle. Means, password storage means, vehicle characteristic storage means and operation permission means are included in the display device.

Since many industrial vehicles are equipped with a display device for displaying information on the operating state of the vehicle, the display device has an input means, a password storage means,
It can be made compact by including the vehicle characteristic storage means and the operation permission means. It is also convenient for displaying the management data on the display device as described above.

Therefore, as described in claim 6, it is more preferable if the clocking means, the data creating means and the data storing means according to claim 4 are included in the display device. The industrial vehicle according to claim 7 is the industrial vehicle according to claim 5 or 6, wherein the display device displays the content of the input when an input operation is performed through the input means, and thus the input content is displayed. It can be confirmed, and for example, erroneous input can be prevented. When the input operation is performed via the input means, the display device displays the data instructed by the input operation, so that the necessary data can be displayed at any time.

The industrial vehicle according to claim 8 is the industrial vehicle according to any one of claims 5 to 7, wherein the display device stores information stored in the password storage means, vehicle characteristic storage means or data storage means. Since it has an external output means for outputting to the outside, as described above, the data is taken out to an external device (for example, a personal computer),
It can be displayed or printed on the display. This makes it extremely easy to manage for each operator, such as who uses how many vehicles.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to an example in which the present invention is applied to a forklift.

[0019]

Embodiment 1 As shown in FIG. 1A, a display device 3 is provided on an instrument panel 2 of a forklift 1.
Is installed. This display device 3 is shown in FIG.
As shown in (b), the liquid crystal panel 14 and the selection switch 15
And so on. The liquid crystal panel 14 displays various information of the forklift 1, for example, traveling speed, traveling distance, fuel remaining amount of engine vehicles, battery remaining amount of electric vehicles, and the like. Although the liquid crystal panel 14 is used in this example,
It is also possible to employ another type of display means, such as CRT or EL (electroluminescence). The selection switch 15 corresponds to an input unit, and various inputs can be performed by operating the selection switch 15.

As shown in FIG. 2, the display device 3
Is mainly composed of a control unit 11 which is a microcomputer (one-chip microcomputer) including a well-known CPU, ROM, RAM, input / output circuit and the like. The above-mentioned selection switch 15 is connected to the control unit 11, and the driver 18
The liquid crystal panel 14 is also connected via. That is,
The control unit 11 can input the ON signal of the selection switch 15 and can control the display of the liquid crystal panel 14.

Further, the control unit 11 has a real time clock (RTC) 12 corresponding to a time measuring means, a password storing means, a dedicated memory 13 serving as a vehicle characteristic storing means and a data storing means, a communication circuit 16 and an input / output (I / I). O) The interface 17 is also connected.

The RTC 12 can measure the date (including the day of the week) and the time, and the control unit 11 sends these data to the RTC 1
It can be obtained from 2. The dedicated memory 13 is an EEPROM,
It is divided into a storage area (password area) for storing passwords and vehicle characteristic settings and a storage area (data area) serving as data storage means. The storage of the password area is not overwritten (updated) unless overwriting is instructed, but when the storage capacity of the data area is full, new data is overwritten on the oldest data. In the case of the present embodiment, the storage capacity of the data area is such that the management data for approximately one month can be stored in the usage state assumed to be standard.

A connector 16a is attached to the communication circuit 16, and communication with an external device (for example, a personal computer) 20 connected via the connector 16a can be executed. Therefore, the control unit 11 can acquire data and commands from the external device 20, and can send the information stored in the RAM of the control unit 11, the dedicated memory 13, or the like to the external device 20.

Explaining the case of an engine vehicle, the input / output interface 17 has an engine controller (not shown).
Are connected, and the control unit 11 can communicate with the engine controller. The input / output interface 17 includes a key switch (key SW), an accelerator switch (accelerator SW) that is turned on when the accelerator is depressed,
A cargo switch (cargo SW) such as a lift switch that is turned on when the lift lever is operated or a tilt switch that is turned on when the tilt lever is operated, and various sensors and switches are connected, and a switch on / off signal is connected. , Traveling pulses from a rotary encoder that outputs a pulse signal corresponding to the amount of rotation of the wheels (that is, traveling distance), and signals from other sensors and switches are input.

The control unit 11 is based on the time data from the RTC 12 and the input information from the above switches and the like.
Data relating to traveling and cargo handling operations is created and stored in the dedicated memory 13 as part of the management data. For example, the control unit 11 can recognize the start and stop of the traveling from the input state of the traveling pulse, can identify those times by referring to the time data from the RTC 12, and calculate the traveling distance by counting the traveling pulses. it can. Further, the cargo handling time can be calculated from the on / off times of the cargo handling switch. The control unit 11 sequentially accumulates the operation time and traveling distance of traveling, cargo handling, etc. calculated in this way and stores them in the dedicated memory 13. This integrated value is recorded in the dedicated memory 13 in units of an appropriate time, such as a half day or a day. In this embodiment, the working time of one day is divided into morning and afternoon, and is recorded on a half-day basis.

The management data recorded in the dedicated memory 13 is displayed on the liquid crystal panel 14 in the form of, for example, today's, yesterday's, past one week, etc. by operating the selection switch 15 to instruct. . Further, when the external device 20 is connected to the display device 3, the dedicated memory 1
The desired data in 3 can be requested and acquired from the external device 20.

Further, a start control circuit 60 is connected to the input / output interface 17. Start control circuit 60
Are a starter switch 61, a battery 62, a starter switch 63a and a key switch 63b, a key switch unit 63 including a microcomputer input (key switch operation confirmation), a start prohibition relay 65, a start prohibition relay (B) contact 6
6, the starter relay 64 and the starter relay (A) contact 67 are configured as illustrated. With this circuit configuration, if the starter switch 63a is turned on when the start inhibition relay (B) contact 66 is closed, the starter relay 64 operates and the starter relay (A) contact 67.
Is closed, electric power is supplied to the starter motor 61 to start the engine. On the other hand, if the start prohibiting relay (B) contact 66 is open, the starter relay 64 does not operate even if the starter switch 63a is turned on, so that electric power is not supplied to the starter motor 61. Since the start prohibition relay (B) contact 66 is driven by the start prohibition relay 65, the controller 11 causes the start prohibition relay 65 to start.
The engine start can be permitted or prohibited by controlling the engine. The control unit 11 starts each control only after confirming that the key switch 63b is turned on (key on). When the starter switch 63a is turned on and the start prohibition relay 65 is not operating, the starter motor is operated for the first time to start the engine.

The management process performed by the control unit 11 will be described in detail with reference to a flowchart and the like. In the present embodiment, the password for specifying each of the plurality of operators has already been set by operating the selection switch 15,
It is assumed that the password is stored (registered) in the password area.

First, the management process started by the control unit 11 due to the turning on of the key switch will be described with reference to the flowchart of FIG. In the management process, first password process 1
Execute (S101). Here, the control unit 11 displays a password input screen on the liquid crystal panel 14 and prompts the user to enter the password. When the operator operates the selection switch 15 to input a password, it is determined whether or not the password is stored (registered) in the password area of the dedicated memory 13. Incidentally, in response to the operation of the selection switch 15, for example, the movement of the cursor, blinking, change in brightness at the time of confirmation, etc. are displayed on the liquid crystal panel 14, so that the selection operation can be performed while watching this. The same applies to input operations in other situations.

If the input password is registered, the control unit 11 operates the start prohibition relay 65 to close the start prohibition relay (B) contact 66. As a result, the starter switch 63a is turned on, the starter motor 61 is rotated, and the engine is started. However, if the entered password is not registered, the control unit 11 does not operate the start prohibition relay 65. Therefore, the engine cannot be started.

When the engine can be started, the control unit 11 proceeds to the next password process 2 (S102). However, if it is impossible to start the engine, the process does not proceed to the next process. For example, the password is incorrect, so a message prompting the liquid crystal panel 14 to re-enter is displayed, and then the password entry screen is displayed again. Let In addition, if the re-input is accepted up to three times, but the registered password is still not input, the liquid crystal panel 1
Display the error in 4 and stop the operation.

As shown in FIG. 4, in the password processing 2, the password data is confirmed, the vehicle characteristic data corresponding to the password is read from the dedicated memory 13 and the vehicle characteristic setting is changed (S105). When the vehicle characteristic data corresponding to the password is not stored, the vehicle characteristic is set as the default value. The control unit 11
The operation of the forklift 1 is controlled based on the updated vehicle characteristics in cooperation with the engine controller.

As illustrated in FIG. 5, password data is stored in the password area in a data structure including a password rank, a password, initials and characters indicating an operator, and the like. Next, work start data, for example, a password confirmation number, various data at the work start time including date and time, data at key-on, etc. are stored (S106). Then, an initial display (for example, refer to FIG. 6) indicating that the person has been confirmed is displayed on the liquid crystal panel 14 (S107), and the process returns. The initial display in FIG. 6 is “Good morning” because it is an example in the morning, but it may be appropriately displayed according to the time zone and the like.

Then, as shown in FIG. 3, the management data stored up to the previous time in the dedicated memory 13 is read into the RAM (S120), and the detection time is read by the forklift 1.
(S130). Actually, the time is calculated by the pulse count of the internal clock (1 Hz), and therefore, the count value of the pulse is stored as “time”. Hereinafter, the same applies to the time. It should be noted that it is possible to store the actual time with reference to the RTC 12, and this may be done.

Subsequently, it is determined whether or not the accelerator switch is turned on (S140), and if the determination is affirmative, the detection time is stored as the start time of the operator's acceleration request (S150), and S160 is executed. move on. When the accelerator switch ON is not detected (S140: NO), S
Move to 160.

In S160, it is determined whether or not the cargo handling switch is turned on. If the determination is affirmative, the detection time is stored as the start time of the cargo handling work (S170) and S18.
Go to 0. On the other hand, when it is not detected that the cargo handling switch is turned on in S160 (S160: NO), the process proceeds to S180.

In S180, it is determined whether or not the input of the traveling pulse is started. When the input of the traveling pulse is started (S180: YES), the time when the input of the traveling pulse is started is set as the traveling start time. It is stored and the counting of running pulses is started (S190). On the other hand, when the traveling pulse is not detected in S180 (S180: N
O), jump S190.

At S192, it is determined whether or not there is an input for changing the vehicle characteristic, and if the input for changing the vehicle characteristic is made (S192: YES), the current vehicle characteristic is updated to the changed value (S192). S194). If a negative determination is made in S192, the process jumps to S194.

Subsequently, it is determined whether or not the accelerator switch is turned off (S200), and if the determination is affirmative, the time when the accelerator switch is detected to be off is stored as the end time of the acceleration request (S210). On the other hand, when the accelerator switch OFF is not detected in S200 (S2
00: NO), jumps to S210 and proceeds to S220.

The process of S200 is a process on the premise that the accelerator switch is switched on in S140, and detects the switching operation of the accelerator switch from on to off. Therefore, if the accelerator switch is not switched on and remains off in S140, it is not a change from on to off because it is not in S200.
Then it becomes a negative judgment.

Subsequently, it is determined whether the cargo handling switch has been turned off (S220), and if the determination is affirmative, the time at which the switch to off is detected is stored as the finish time of the cargo handling work (S230). On the other hand, when the switching of the cargo handling switch to off is not detected in S220 (S22
0: NO), and proceeds to S240.

Similar to S200, this S220 detection process is a process that is premised on that the cargo handling switch is switched on in S160, and detects the switching operation of the cargo handling switch from on to off. Therefore, S160
If the cargo handling switch is not turned on and remains off in step S220, it means that the change from on to off does not occur.
Then it becomes a negative judgment.

Subsequently, it is determined whether or not the state in which no traveling pulse is input continues for a certain time or more (the forklift 1 is stopped for a certain time or more) (S240).
If the state in which the traveling pulse is not input continues for a certain time or longer (S240: YES), the traveling pulse counting process is temporarily terminated, and the time at that time is stored as the traveling end time (S250). On the other hand, a negative determination is made in S240 (whether the traveling pulse is input or the interruption time is less than the set value)
When (S240: NO), the process proceeds to S260.

The detection process of S250 is also a process premised on the detection of the start of the running pulse input in S180. Therefore, if the traveling pulse is not detected in S180 and the forklift 1 is stopped, S240 and S250 are not executed. Then, it is determined whether or not the key switch is turned off (S260), and if the determination is affirmative (S260).
260: YES), and the time when the off state is detected is stored as the work end time of the forklift 1 (S270).

When it is not detected that the key switch is off in S260 (S260: NO), the process returns to S140 and the above-described processes of S140 to S250 are repeated. Following S270, the password work management process (S
271) is executed. As shown in FIG. 7, in the password work management process, first, each work data of today is totaled for each password (for each operator) (S273). The total content is, for example, B: vehicle operating time stored when key is off, B1, B2 ... Bx is each working time, A: vehicle operating time stored when key is on, A1, A
2 ... Ax is each work time.

Next, it is judged whether or not the work data or vehicle data (for example, vehicle characteristics) has been changed since the key was turned on (S274). If there is a change, each work data of today is calculated based on the calculation result of S273. Integrated value (1Total,
2Total ...) is updated. The integrated value (1Total etc.) of each work data for today is cleared due to the date change of the RTC 12.

Subsequently, the data calculated in S275 is stored in the work map, the date is stored, the vehicle characteristics are updated and stored, and each work data is stored in the dedicated memory 13 for each password (S276). Then, a work completion processing display (see, for example, FIG. 8) is displayed on the liquid crystal panel 14 (S2
77), then return.

Returning to the processing of FIG. 3, the ON and OFF times of the key switch, the ON and OFF times of the accelerator switch, the ON and OFF times of the cargo handling switch, and the travel pulses stored in the RAM so far are stored. A dedicated memory that calculates the key switch on time, accelerator switch on time, cargo handling switch on time, travel time, travel distance, etc. based on the count start time and count end time, the number of travel pulses counted, etc. 13 (S2
80). These data are password (operator)
Irrespective of the above, it becomes various data of the forklift 1, for example, on a daily basis.

The work data and the like recorded in the dedicated memory 13 as described above can be displayed on the liquid crystal panel 14 by operating the selection switch 15 to instruct the display device 3. For example, by designating a password (operator), as shown in FIG. 9A, the work record of each operator is displayed, or without designating the password (operator), as shown in FIG. 9B. Work data on the forklift 1 can be displayed. To specify the password, select switch 1
The password data shown in FIG. 5 may be displayed on the liquid crystal panel 14 and selected from among them, which is simple.

If the same operation is performed by the external device 20 connected to the display device 3, the data recorded in the dedicated memory 13 can be fetched and stored in the external device 20, or displayed on the display of the external device 20, It is possible to print with a printer connected to the external device 20.

As described above, in the forklift 1 of this embodiment, the password for each operator set by the input operation via the selection switch 15 is set and stored in the dedicated memory 13, and also via the selection switch 15. The vehicle characteristic set corresponding to the password by the input operation is stored in the dedicated memory 13 in association with the password.

When the selection switch 15 is operated and a password is input after the key is turned on, the control unit 11 determines whether or not the input password is stored in the dedicated memory 13, and the corresponding password is stored. Sometimes (when registered) allows the engine to start, otherwise it prevents the engine from starting.

Then, the control unit 11 reads out the vehicle characteristic corresponding to the password from the dedicated memory 13 and changes the setting, and controls the operation of the forklift 1 based on the vehicle characteristic, so that a plurality of operators use one forklift. When 1 is used, if the vehicle characteristic is set according to each password and one's preference, it is not necessary to reset the vehicle characteristic each time it is used.

Further, the vehicle data generated or changed with the operation of the forklift 1 is acquired, and the control unit 11 creates the management data associated with the time and the password measured by the RTC 12, and the management data is stored in the dedicated memory. 1
3, the management data can be created and stored for each password, that is, for each operator.

This management data can be displayed on the liquid crystal panel 14 of the display device 3, or can be output to the external device 20 to be displayed or printed on the display, so who can utilize how much the vehicle. This makes it extremely easy to manage each operator.

When the purpose is only to manage the work time of each operator, collation of passwords and correspondence between passwords and vehicle characteristics are unnecessary. In this case, if the operator operates the forklift 1 by displaying a list of operator names and characters identifying the operator on the liquid crystal panel 14 of the display device 3 by key-on and selecting the operator from this list. Good.

Second Embodiment Although the first embodiment is an example in which the present invention is applied to a forklift configured as an engine vehicle, the present invention can also be applied to a forklift configured as an electric vehicle. 2 will be described. Since there are many parts in common with the first embodiment, the same reference numerals as those in the first embodiment are used for the common parts and the description thereof is omitted.

As shown in FIG. 10, in the case of the present embodiment, the vehicle control device 30 that comprehensively controls the traveling of the forklift 1 and the cargo handling operation by controlling various drive units such as a traveling motor and a cargo handling motor. And is connected to the control unit 11 via the input / output interface 17. Key switch, accelerator switch, cargo handling switch,
A signal such as a traveling pulse is input to the input / output interface 17 of the display device 3 via the vehicle control device 30.

The input / output interface 17 is also connected to a charging unit 40 for charging a battery (not shown), a key switch and the like. Vehicle control device 30
Is the well-known C as in the control unit 11 of the display device 3.
It is a microcomputer (one-chip microcomputer) including a PU, a ROM, a RAM, an input / output circuit, and the like. The vehicle control device 30 operates in accordance with a program stored in the ROM, and controls each drive device based on signals from these switches and sensors to control traveling and cargo handling operations. Input information such as signals from switches and sensors is displayed on the display device 3 (more precisely, the control unit 1).
It is sent to the display device 3 in response to the request from 1).

The charging unit 40 is a device for controlling and managing the charging time of the battery mounted on the forklift 1 and the charging modes such as automatic charging and rapid charging. The charging unit 40 starts charging to the control unit 11. , A signal indicating termination and charging mode is sent. Therefore, the control unit 1
1 is the time data from the RTC 12 and the charging unit 40.
It is possible to recognize the charging start and end times, the charging time, the number of times of charging, etc. based on the signal from, and write such data in the dedicated memory 13 as a part of the management data. This data is also recorded in the dedicated memory 13 in units of, for example, half a day or one day, like the data of traveling and cargo handling.

The management process started by the control unit 11 of this embodiment is as shown in FIG. 11, and the password process 1 (S
101) is executed. Similar to the first embodiment, this process is a process that enables the forklift 1 if the entered password is registered, and disables the forklift 1 if it is not registered.

The difference from the first embodiment is that the mode of the vehicle control device 30 is switched instead of the process for permitting or prohibiting the engine start. Specifically, the control unit 11
Sends an operation permission signal to the vehicle control device 30 if the entered password is registered, and sends an operation disapproval signal if not registered.

When the vehicle control device 30 receives the operation permission signal, the vehicle control device 30 validates the inputs of the accelerator switch, the cargo handling switch, and the like, and controls each drive device based on those input signals, that is, the traveling and cargo handling operations. Becomes a runnable mode. However, when the operation permission / prohibition signal is received, the mode in which the input of the accelerator switch, the cargo handling switch or the like is invalid and is not accepted, that is, the mode in which the traveling or the cargo handling operation is not executed is performed.

The subsequent password process 2 (S102), the process of reading each data from the dedicated memory 13 (S120), and the storage of the key-on time (S130) are the same as those in the embodiment. Next, the control unit 11 determines whether or not it is a data input timing (S133), and if the determination is affirmative, the control unit 11 requests the vehicle control device 30, and the vehicle control device 30 adds and stores the mileage, the total cargo handling time, Data such as total running time and total key-on time is acquired and stored (S
135). This data acquisition is S15 in the first embodiment.
0, S170, S190, S210, S230, S25
Although it corresponds to 0, since the data has already been calculated by the vehicle control device 30, the control unit 11 does not need to perform the calculation process of the traveling distance and the like again, and the load on the control unit 11 is small.

Of course, as in the first embodiment, the time when the accelerator switch is turned on, the time when the cargo handling switch is turned on, the time when the input of the traveling pulse is started,
The control unit acquires data such as the time when the accelerator switch is turned off, the time when the cargo handling switch is turned off, the time when the travel pulse input is stopped, and the travel pulse count or travel distance at that time. The calculation processing may be performed at 11.

Next, as in the first embodiment, steps S192 and 194 are executed. However, if there is an input for changing the vehicle characteristic (S192: YES), the current vehicle characteristic is updated to the changed value and transmitted to the vehicle control device 30 (S1).
