Description

  The present invention relates to a technique for limiting the vehicle performance of an industrial vehicle.

  In industrial vehicles such as forklifts, in order for an operator to achieve fuel-efficient driving and safe driving, it is basically effective to observe driving rules while avoiding sudden driving. Here, although the fuel consumption of an industrial vehicle is reduced by avoiding sudden acceleration or sudden deceleration, it is known that this method causes a reduction in the efficiency of work using the industrial vehicle (for example, Patent Document 1). reference).

JP 2011-37530 A

  As described above, low fuel consumption driving and safe driving can be achieved by limiting the vehicle performance of an industrial vehicle, for example, limiting acceleration to a certain value or less. However, since there are individual differences in the operation method by an operator of an industrial vehicle, there is a possibility that an operator who cannot achieve the work amount to be performed during working hours may appear when the vehicle performance is limited in this way.

  In general, an operator's business can be regarded as the number of packages to be carried during working hours and the time to be processed (carryed). It has been difficult for an administrator who manages this work to grasp the minimum vehicle capability that allows all operators to carry out the work (that is, the amount of work) within working hours.

  For example, if the administrator limits the vehicle performance to a value below the above-mentioned minimum vehicle capacity, some operators carry the number of packages specified by the administrator within the specified time. I can't do that. That is, there is a problem that the efficiency of work using an industrial vehicle is reduced by limiting the vehicle performance.

  The present invention has been made to solve such a problem, and an object thereof is to suppress a decrease in work efficiency while realizing a low fuel consumption driving and a safe driving.

  The vehicle performance limiting device for an industrial vehicle according to claim 1, which has been made to achieve the above object, includes a limiting means for limiting the vehicle performance of the industrial vehicle, and an information value for determining the content of the limitation by the limiting means. Information value acquisition means for acquiring, target value acquisition means for acquiring a target value of the amount of work achieved by an operator of the industrial vehicle within working hours, and the vehicle performance limited by the limiting means based on the information value Within the range, the determination means for determining whether the target value can be achieved within the working hours, and the limit when the determination means determines that the target value cannot be achieved within the working hours Relaxation correction means for performing correction for relaxing the contents of the vehicle performance restriction by the means, and the restriction means restricts the vehicle performance based on a correction result by the relaxation correction means. .

  In the invention according to the first aspect as described above, since the vehicle performance is limited, it is possible to realize fuel-efficient driving and safe driving. By the way, as the information value for determining the limitation contents of the vehicle performance, it may be a preset value, a value based on a work amount collected from a specific operator, or a work amount collected from a plurality of operators. A value based on a leveled value may be used.

  In the invention described in claim 1, the operator achieves the target value within the working hours because the vehicle performance restriction is corrected (relaxed) so that the target value of the workload can be achieved within the working hours. It can be expected that the error between the work amount managed by the administrator and the work amount actually performed by the operator can be reduced.

Therefore, according to the first aspect of the present invention, it is possible to suppress a decrease in work efficiency while realizing low fuel consumption driving and safe driving.
Further, the target value may be number information indicating the number of luggage to be transported by the operator during working hours.

  That is, the number information is information necessary for determining the work amount of the operator. Therefore, the work amount of the operator can be obtained more accurately by using the number information as the target value.

  Also, in the invention described in claim 1 or claim 2, as in claim 3, when the determination unit determines that the target value cannot be achieved within the working hours, a notification operation is performed. It is good to have a reporting means.

  According to this, when it is determined that the target value cannot be achieved within the working hours, the notification operation is performed, and thus the administrator may notice that the target value needs to be corrected by the notification operation. it can.

  According to a fourth aspect of the present invention, there is provided a vehicle performance limiting device for an industrial vehicle, a limiting means for limiting the vehicle performance of the industrial vehicle, and an information value acquiring means for acquiring an information value for determining the content of the restriction by the limiting means. A target value acquisition unit that acquires a target value of a work amount that the operator of the industrial vehicle achieves within working hours, and the target within a range of the vehicle performance limited by the limiting unit based on the information value Determination means for determining whether or not the value can be achieved within working hours, and notification means for performing a notification operation when the determination means determines that the target value cannot be achieved within the working hours. It is characterized by that.

According to this, similarly to the first aspect, since the vehicle performance is limited, low fuel consumption driving and safe driving can be realized.
In addition, when it is determined that the target value of the workload cannot be achieved within the working hours, since the notification operation is performed, the administrator notices that the target value needs to be corrected by the notification operation, and the administrator An error between the amount of work to be managed and the amount of work actually performed by the operator can be suppressed.

Therefore, according to the fourth aspect of the present invention, it is possible to suppress a decrease in work efficiency while realizing low fuel consumption driving and safe driving.
By the way, as described above, when the operator cannot achieve the target value within working hours, it is conceivable to correct the target value.

  Therefore, as described in claim 5, if the notification means prompts the operator to increase the working hours of the operator as the notification operation, the administrator who has received the notification operation increases the operator's working hours, thereby Will be able to achieve the target value within working hours.

  By the way, in invention in any one of Claims 1-5, when it determines with the said target value being achievable within working hours by the said determination means as described in Claim 6, by the said limitation means It is preferable to provide strengthening correction means for performing correction so that the content of restriction becomes more severe.

  In other words, in the invention described in claim 6, when the operator's work amount (target value) has a margin, the restriction content of the vehicle performance is further tightened (strengthened). For this reason, it is possible to realize further fuel-efficient driving while effectively using working hours.

  According to a seventh aspect of the present invention, there is provided a vehicle performance limiting device for an industrial vehicle, a limiting unit for limiting the vehicle performance of the industrial vehicle, and an information value acquiring unit for acquiring an information value for determining the content of the limitation by the limiting unit. A target value acquisition unit that acquires a target value of a work amount that the operator of the industrial vehicle achieves within working hours, and the target within a range of the vehicle performance limited by the limiting unit based on the information value The determination means for determining whether or not the value can be achieved within the working hours, and when the determination means determines that the target value can be achieved within the working hours, the restriction content by the limiting means is more stringent Strengthening correction means for performing correction so that the limiting means limits the vehicle performance based on a correction result by the strengthening correction means.

According to this, similarly to the first aspect, since the vehicle performance is limited, low fuel consumption driving and safe driving can be realized.
Further, in the invention described in claim 7, as in the case of claim 6, when there is a margin in the work amount (target value) of the operator, the restriction contents of the vehicle performance are further tightened (strengthened). For this reason, since the operation with lower fuel consumption can be realized while effectively using the working hours, it is possible to suppress a decrease in work efficiency.

The vehicle performance limiting device 1 is mounted on the forklift. As shown in FIG. 1, the vehicle performance limiting device 1 includes an operation unit 12, a display unit 14, a storage unit 16, a control unit 18, and the like.

The operation unit 12 is for operation by an operator such as a forklift operator or a manager, and the operation unit 12 includes a touch panel, a switch, and the like.
The display unit 14 is for displaying various information, and the display unit 14 is configured by a liquid crystal display or the like.

  The storage unit 16 is composed of a nonvolatile storage medium that can rewrite data. The storage unit 16 stores information values for determining the details of the vehicle performance restriction by the forklift.

  The control unit 18 includes a CPU, a RAM, a ROM, and the like. The control unit 18 includes a lever sensor 2 that detects an operation state of a forklift operating lever, and a weight of a load loaded on the fork of the forklift. A load sensor 3 to detect, a steering sensor 4 to detect the steering angle of the forklift, a vehicle speed sensor 5 to detect the speed (vehicle speed) of the forklift, a key sensor 6 to detect the on / off state of the forklift, and the remaining amount of fuel An output signal from the remaining amount detection sensor 7 or the like for detecting is input.

  The control unit 18 is configured to be able to control the traveling motor 8 used during the forklift traveling operation and the cargo handling motor 9 used during the forklift loading operation. The control unit 18 includes various sensors. A control signal for driving the motor is output to the motor drive unit 10 based on the signals (operations performed by the operator) input from 2 to 7. The motor driving unit 10 to which this control signal is input drives the traveling motor 8 or the cargo handling motor 9 in accordance with the control signal from the control unit 18.

  In addition, the control unit 18 performs a collection process for collecting information necessary for setting information values, a restriction content setting process for setting a restriction content for forklift vehicle performance, a restriction process for limiting vehicle performance, and the like. Do.

2. Flow until an information value is set In the first embodiment, an information value is set based on various types of information collected by the collection process of the control unit 18, but in the following description, this information value is set. The flow up to will be described.

First, in the control unit 18, the collection process is always executed while the forklift is powered on.
In this collection process, based on the output signals from the various sensors 2 to 7, the number of cargo handling operations representing the number of loads carried by the forklift, the cargo handling time representing the time when the cargo handling operation was performed, and the time during which the forklift is traveling Information such as travel time, working hours, working hours, luggage weight, vehicle speed, travel distance, acceleration, turning speed, switchback vehicle speed (speed at the time of forward / reverse switching operation), fuel consumption, etc., are measured. The result is stored in the storage unit 16.

  In the first embodiment, from the time when the power of the forklift is first turned on after the reference time (for example, midnight) to the time when the power of the forklift is finally turned off before the reference time on the next day. The time is defined as “working time”, and the time during which the forklift travel or transport operation is performed within the working time is defined as “working time”.

  Of the information measured by the collection process, the vehicle speed, acceleration, turning speed, and switchback vehicle speed are stored in the storage unit 16 as roughness information that represents the roughness of driving by the operator.

  Then, the control unit 18 substitutes the information stored in the storage unit 16 into the following formulas 1 to 3, so that the average fuel consumption consumed by the forklift to carry one piece of cargo, and one forklift. The average transport time spent for transporting the load and the operation rate indicating the ratio of the forklift actually traveling or handling during the working hours are calculated.

Average fuel consumption = Fuel consumption / Number of cargo handling operations (1)
Average transport time = Operating time / Number of cargo handling operations (2)
Occupancy rate = Operating hours / Working hours (3)
Then, the average fuel consumption, the average transportation time, and the operation rate calculated by the control unit 18 using the above-described equations 1 to 3 are stored in the storage unit 16.

  Further, the control unit 18 measures a rate (acceleration excess rate) in which the acceleration exceeds a reference value per unit time (average transport time in the first embodiment) based on the information on the acceleration. The acceleration excess ratio is stored in the storage unit 16 as roughness information. At this time, the acceleration excess ratio is stored in a state associated with the average transportation time and the average fuel consumption.

  Information (roughness information, average fuel consumption, average transportation time, operating rate, etc.) stored in the storage unit 16 by the collection by the control unit 18 as described above is sent to a management center (not shown). The above information is sent to the management center from all forklifts to be managed.

  Information sent to the management center is managed for each forklift, and this information is accumulated for a certain period (for example, one year). Further, an average value is calculated and stored for each type of information. It has become. In the first embodiment, in addition to calculating the average value for each forklift, the entire average value is also calculated and stored.

  Based on the information sent from all the forklifts (average transport time, average fuel consumption, excess acceleration rate), the management center determines the correlation between average transport time, average fuel consumption, and excess acceleration rate. The relational expression to represent is calculated.

  It is well known that the average transportation time, the average fuel consumption, and the acceleration excess ratio are correlated, for example, “average fuel consumption = coefficient A × acceleration excess ratio + coefficient B” or “acceleration excess ratio”. = Coefficient C × average transport time + coefficient D ”.

  In the first embodiment, the overall average value calculated by the management center and the relational expression are set as information values. The information value set on the management center side in this way is sent to each forklift and stored in each storage unit 16.

  In the first embodiment, among the information values stored in the storage unit 16, roughness information (vehicle speed, excess acceleration ratio, acceleration, etc.), working hours, average fuel consumption, and the like are used as initial values of vehicle restrictions. Is set.

  Note that any means may be adopted as means for sending the information stored in the storage unit 16 to the management center and means for sending the information value set on the management center side to each forklift. For example, a communication unit capable of communication between the forklift and the management center may be provided in the forklift and the management center, and information may be exchanged by data communication, or a removable storage device may be used. . When the storage device is used, for example, an operation may be adopted in which the administrator manually connects the storage device to the management center and the forklift and copies necessary information.

3. Restricted Content Setting Process FIG. 2 is a flowchart showing a process executed by the control unit 18 of the vehicle performance limiting device 1. This process is performed when a limited content setting operation is performed by the operator via the operation unit 12. To be executed.

  When the control unit 18 starts the process shown in FIG. 2, first, in S <b> 110, it is determined whether or not the target value of the work amount that the operator achieves during working hours is input via the operation unit 12. In the first embodiment, for example, the number of scheduled cargo handling operations that represents the expected number of packages to be transported by the operator during working hours, such as the number of packages to be transported planned on a slip or the like, is set as the “target value”.

  The process of S110 is repeatedly executed until it is determined that the target value has been input. If it is determined that the target value has been input (S110: YES), it is determined that the target value has been acquired, and the process proceeds to S120. Migrated.

In S120, information values in the storage unit 16 (transportation time, operation time, fuel consumption, average value such as excess acceleration ratio, and relational expressions) are acquired.
In S130, whether or not the operator can achieve the target value input in S110 within the working hours within the range of the vehicle performance limited by the control unit 18 (that is, input via the operation unit 12). Whether or not the number of packages can be transported by the operator within working hours).

  Here, in S130, the estimated value of the average transportation time is calculated by substituting the target value input in S110 and the average value of the operation time, which is the information value acquired in S120, into the above-described equation 2. When the excess acceleration ratio and average fuel consumption derived by substituting this estimated value into the above relational expression are smaller than the information value acquired in S120, it is determined that the target value can be achieved within working hours. The

  If it is determined in S130 that the target value cannot be achieved within working hours (S130: NO), that effect is displayed on the display unit 14 (S140), and the process proceeds to S150.

  In S150, a restriction relaxation correction process for performing correction for relaxing the restriction content is executed. Specifically, based on the information value acquired in S120, extension of working hours, relaxation of vehicle speed limit, relaxation of average fuel consumption, or so as to achieve the target value within working hours, or Mitigation of excess acceleration rate.

When the restriction relaxation correction process in S150 ends, in S180, the correction content is registered in the storage unit 16 as a new restriction content, and the restriction content registration process in FIG. 2 ends.
On the other hand, if it is determined in S130 that the target value can be achieved within working hours (S130: YES), the process proceeds to S160, and in S160, the end time is estimated from the time when the target value is estimated to be achieved. It is determined whether the time until (that is, the remaining working hours) is a certain time (for example, 1 hour) or more (S160).

  If it is determined in S160 that the remaining working time is less than the predetermined time (S160: NO), the process proceeds to S180, and the current restriction content is maintained in S180.

  On the other hand, if it is determined in S160 that the remaining working hours are equal to or longer than a certain time (S160: YES), it is determined that there is enough time even after the goal is achieved. The restriction strengthening correction process is executed.

  Here, in S170, based on the information value acquired in S120, the vehicle speed limit is strengthened, the average fuel consumption is strengthened, and the acceleration excess ratio is strengthened within a range in which the target value can be achieved within working hours. The process of strengthening the contents of vehicle restrictions such as is performed.

When the process of S170 is completed, in the subsequent S180, the correction content strengthened (corrected) in the process of S170 is registered in the storage unit 16 as new restriction content.
4). Vehicle Performance Limiting Process FIG. 3 is a flowchart showing a vehicle performance limiting process executed by the control unit 18 of the vehicle performance limiting device 1, and this process is executed when the forklift is turned on.

  When the control unit 18 starts the vehicle performance restriction process shown in FIG. 3, first, in S210, the vehicle performance restriction content stored in the storage unit 16 is read, and in the subsequent S220, the restriction content read in S210 is read. Based on this, a restriction process for restricting the vehicle performance is executed.

  Here, the restriction process of the first embodiment outputs a control signal corresponding to the input signals from the various sensors 2 to 7 to the motor drive unit 10, and the forklift vehicle based on the input signals from the various sensors 2 to 7. When it is assumed that the performance exceeds the limit, a process of suppressing the output signal to the motor drive unit 10 to a predetermined limit value is performed.

  The restriction process of the first embodiment is repeatedly executed until the power of the forklift is turned off. If the restriction content is changed in the restriction content registration process, the current restriction content is changed to that after the change. The restriction process continues with the change.

5. As described above, in the first embodiment, since the vehicle performance is limited (S220), low fuel consumption driving and safe driving can be realized.

  In the first embodiment, the vehicle performance limit is corrected (relaxed) so that the target value of the workload can be achieved within the working hours (S150), so that the operator achieves the target value within the working hours. It can be expected that the error between the work amount managed by the administrator and the work amount actually performed by the operator can be reduced.

Therefore, according to 1st Embodiment, the fall of work efficiency can be suppressed, implement | achieving low fuel consumption driving | operation and safe driving | operation.
In addition, since the target value of the first embodiment uses information necessary for determining the operator's workload, the operator's workload can be obtained more accurately.

  Further, in the first embodiment, when it is determined that the target value cannot be achieved within the working hours (S130: NO), a notification operation is performed (S140). Therefore, the administrator corrects the target value by the notification operation. Can realize that is necessary.
