Description

  The present invention relates to an operation parameter setting device for a battery-powered vehicle or the like, and more particularly to an operation parameter setting device suitable for a battery-driven forklift or the like.

  Conventionally, in a battery-powered vehicle represented by a forklift, operation parameters related to traveling power (acceleration force), cargo handling performance, etc. have been set according to the operator's driving technology and on-site operating conditions (Patent Document 1, Patent) Reference 2).

  When working with a battery-driven forklift, it is necessary to adjust the reaction speed of various levers and the like according to the driving skill of the driver. In other words, when adjustments are made to increase the reaction speed of various levers for those who are unskilled in driving skills, the response of the forklift cannot catch up with the skills of the driver, and smooth operations cannot be performed. there were. On the other hand, when adjustment is made so that the reaction speed of the response lever or the like is slowed for a person with excellent driving skills, work efficiency may not be good.

  In addition, it is necessary to adjust the reaction speeds of various levers and the like so that the work efficiency is optimal according to the operating conditions at the site. Thus, safe and efficient work can be performed by setting reaction speeds of various levers, that is, operation parameters to appropriate values.

  Further, in order to prevent theft of a battery-powered vehicle or the like and allow only a person with proper driving qualification to perform driving, it is necessary to perform vehicle management by inputting a password or the like. For this reason, various civil engineering machines equipped with a security system have been proposed (see Patent Document 3).

  However, in order to set an operation parameter in a conventional battery-powered vehicle, it has been necessary to operate a volume installed on the dashboard or an operation switch provided in the meter panel.

  For example, an operation switch arranged in a meter panel of a general forklift has an up key for inputting a setting value, a shift key for moving and selecting a setting item having a hierarchical structure, and a selection change of the setting item. There are only three mode keys, and setting a plurality of types of operation parameters using only these three switches requires a complicated operation procedure, and it is difficult to say that the operability is good.

  In particular, the up key for entering the set value has only the function of cyclically increasing the numerical value.To set a smaller numerical value, after passing a large numerical value, the numerical value from the minimum value is changed again. It was necessary to raise it, and the operation was troublesome. In order to cope with such inconvenience, it is sufficient to provide a down key. However, the space in which the operation switch can be arranged in the meter panel is not so large, and the cost increases if the number of parts is further increased. Since it rises, it is not a good idea to provide a separate down key that is not used frequently.

  The operation parameters are not frequently set, and may be set only when the driver is changed or when the on-site operating status is changed. Therefore, if a volume or operation switch that is not so frequently used can be omitted, the number of parts can be reduced, the number of assembly steps can be reduced, and the cost can be reduced.

  The present invention has been proposed in view of the above-described circumstances, and an object thereof is to provide an operation parameter setting device that is excellent in operability and can reduce manufacturing costs.

The operation parameter setting device of the present invention has the following features in order to achieve the above-described object.
That is, the operation parameter setting device of the present invention relates to input means for inputting data relating to the operation parameters, display means for displaying data relating to the operation parameters input by the input means, and operation parameters input by the input means. In an operation parameter setting device comprising storage means for storing data, and mode transition instruction means for instructing transition to an operation parameter adjustment mode by the input means,
The input means includes rotation detection means for detecting the rotation of the driving handle, and increases or decreases data values related to driving parameters in accordance with the rotation of the driving handle detected by the rotation detection means. is there.

  Further, the input means includes movement detection means for detecting movement of the operation lever, and according to the movement of the operation lever detected by the movement detection means, the data value related to the operation parameter is increased or decreased. To do.

  Here, each means and the like will be described in detail. The display means is composed of, for example, a meter panel having a liquid crystal display device, the storage means is composed of, for example, a rewritable EEPROM, and the mode transition instruction means is For example, it is comprised by the operation switch arrange | positioned in the meter panel.

  Further, the rotation detection means is constituted by, for example, a pulse encoder provided on the rotation shaft of the driving handle, and the movement detection means is constituted by a limit switch provided on the operation lever. The operation lever refers to a forward / reverse lever or a lift lever.

  The operation of each means constituting the operating parameter setting device of the present invention is controlled by a control device including a microcomputer having a CPU, a ROM, a RAM, an I / O interface, and the like.

  The operation parameter setting device of the present invention having the above-described configuration can be input by the input means when the mode shift instruction means instructs to shift to the operation parameter adjustment mode.

  Here, when the input means is constituted by the driving handle, for example, when the driving handle is rotated to the left, the rotation detecting means detects the rotation, and decreases the data value related to the driving parameter. Is rotated, the rotation detecting means detects the rotation and increases the data value related to the operating parameter.

  When the input means is constituted by an operation lever (forward / reverse lever), for example, when the forward / backward lever is tilted backward (backward), the movement detection means detects the tilt, and data values related to operation parameters are obtained. On the contrary, when the forward / reverse lever is tilted forward (forward), the movement detecting means detects the tilt and increases the data value related to the operating parameter.

At this time, the display means displays data related to the operation parameter being adjusted by the input means, and the operator can adjust the operation parameter while confirming the data value.
When the operation parameter setting is completed, the set value is stored in the storage means, and the operation state of the vehicle is controlled based on the stored set value.

  Since the driving parameter setting device of the present invention uses a driving handle or an operating lever as means for inputting data relating to driving parameters, the operation is easy and understandable for the operator, and the driving parameters can be adjusted easily. .

  In addition, since the data value of the driving parameter is increased / decreased by using the rotation detecting means for detecting the rotation of the driving handle or the movement detecting means for detecting the movement of the operation lever, the existing parts provided in the vehicle are used. Thus, it is possible to input data relating to operation parameters, and it is possible to reduce costs by reducing the number of parts and the number of assembly steps.

That is, if the shift key 83 provided on the meter panel 80 is operated or the brake pedal is depressed twice within a short time, the setting is completed (S15) and the mode is shifted to the normal mode (S16).
On the other hand, when the setting end operation is not performed, the setting operation is continued (S15).

  When setting the cargo handling system parameter (S9), depending on the form of the input means 10, the operation handle 61 is rotated left or right, or the forward / reverse lever 71 is tilted forward or backward to set a desired set value. Is input (S10).

In order to confirm the input set value, for example, a mode key 84 provided on the meter panel 80 may be operated or a brake pedal may be depressed. That is, when the mode key 84 is operated or the brake pedal is depressed, the input set value is confirmed (S11).
Subsequent setting end operations and the like (S15, S16) are the same as in the case of travel system parameter setting.

  When setting a password (S12), depending on the configuration of the input means 10, the driving handle 61 is rotated left or right or the forward / reverse lever 71 is tilted forward or backward to input a desired password. (S13). At this time, in order to change the digit position of the password, for example, a shift key 83 provided on the meter panel 80 is operated, or an operation such as a so-called double click is performed such that the brake pedal is depressed twice in a short time. Good.

In order to confirm the input set value, for example, a mode key 84 provided on the meter panel 80 may be operated or a brake pedal may be depressed. That is, when the mode key 84 is operated or the brake pedal is depressed, the input set value is confirmed (S14).
Subsequent setting end operations and the like (S15, S16) are the same as in the case of travel system parameter setting.

  If security management using a password is not performed, steps S12 to S24 are not necessary.

Further, the number of setting items and the order of changing the setting items are not limited to those described above, and can be appropriately changed according to the function of the forklift.
In addition, the pedals, keys, and the like used for the setting item changing operation, the setting value confirming operation, and the setting ending operation can be appropriately changed according to the equipment provided in the forklift.
