The driver's seat 106 is provided with an accelerator lever 107, a lift lever 108, a reach lever 109, a tilt lever 110, a headlight switch 111, an emergency stop switch 112, an insertion port 113, a display unit 114, and a key switch 115.

  The accelerator lever 107 is a lever for controlling the forward / backward movement of the vehicle main body 101. The lift lever 108 is a lever for lift control. The reach lever 109 is a lever for reach control. The tilt lever 110 is a lever for tilt control. The headlamp switch 111 is a switch for switching ON / OFF of the headlamp 105. In order to reduce power consumption, when a power plug is connected to the insertion port 113 (during charging), the headlamp 105 is not turned on even if the headlamp switch 111 is turned on. The emergency stop switch 112 is a switch for stopping the entire operation of the forklift 100. When the emergency stop switch 112 is pressed, the entire operation of the forklift 100 is stopped regardless of whether the forklift 100 is traveling and whether it is being charged. The insertion port 113 is a plug receptacle that accepts insertion of a power plug connected to an external power source.

  The display unit 114 is an input / output component that includes a display unit 141 and an input unit 142.

There are three key positions, an OFF position, an ON position, and a start position, in order from the counterclockwise side of the rotatable range of the key. By setting the key position to the OFF position, power supply to the motor and each electrical device is interrupted. In addition, by setting the key position to the ON position, the electric power from the battery 118 is supplied to each electric device, and the electric device becomes operable. Further, when the key is further rotated clockwise from the ON position and the key position is set to the start position (the clockwise end of the rotatable range of the key), a motor (not shown) can be started. Then, after the motor is started, if the rotational force on the key is loosened (the key is released), the key returns to the ON position, and the motor continues to rotate and the forklift 100 can be operated. The key switch 115 is structured such that the key can be removed only when the key position is the OFF position. To prevent malfunction, when a charging plug is connected to the outlet 113 (during charging), even if the key position of the key switch 115 is changed to the ON position or the start position, Power supply is not started.

The auxiliary machine control device 221 includes a connection determination unit 222, a communication determination unit 223, a charge mode determination unit 224, a charge control unit 225, and a behavior control unit 226.
The connection determination unit 222 determines whether or not a power plug is connected to the insertion port 113. For example, the connection determination unit 222 can determine whether or not the power plug is connected by detecting the voltage of the insertion port 113.
The communication determination unit 223 determines whether communication with the display unit 114 is continued. For example, the communication determination unit 223 can determine whether or not communication is continued based on whether or not a response signal is received from the display unit 114 by transmitting a survival confirmation signal to the display unit 114. Further, for example, the communication determination unit 223 can determine whether or not the communication is continued by receiving a survival notification signal that the display unit 114 periodically transmits.
The charging mode determination unit 224 determines whether to start charging control based on whether a signal indicating the charging mode is received from the display unit 114. The charging mode determination unit 224 receives a signal indicating the charging mode from the display unit 114, and determines the charging mode of the battery 118 by the charging control unit 225 as the charging mode indicated by the received signal. In addition, the charging mode determination unit 224 controls the charging based on the state of the headlight switch 111 and the key switch 115 when a power plug is connected to the insertion port 113 and communication with the display unit 114 is interrupted. It is determined whether or not to start.

Further, the behavior control unit 226 controls the lighting of the headlamp 105 according to the operation of the headlamp switch 111 when the power plug is not connected to the insertion port 113.

Next, a charging control method for the forklift 100 according to the present embodiment will be described.
FIG. 4 is a flowchart illustrating a forklift charging control method according to an embodiment.
When the key position of the key switch 115 is switched to the OFF position, the connection determination unit 222 of the auxiliary machine control device 221 determines whether or not a power plug is connected to the insertion port 113 (step S1). When the power plug is not connected to the insertion port 113 (step S1: NO), the auxiliary equipment control device 221 repeats the determination of step S1. On the other hand, when the power plug is connected to the insertion port 113 (step S1: YES), the communication determination unit 223 determines whether communication between the auxiliary machine control device 221 and the display unit 114 is continued. (Step S2).
When communication between the auxiliary machine control device 221 and the display unit 114 is continued (step S2: YES), the charging mode determination unit 224 waits for reception of a signal indicating the charging mode from the display unit 114 (step S3). . When no signal is received from the display unit 114 (step S3: NO), the auxiliary equipment control device 221 returns the process to step S1, and determines whether or not the power plug is connected. On the other hand, when receiving a signal from the display unit 114 (step S3: YES), the charging mode determination unit 224 determines that charging control is started, and the charging mode indicated by the received signal indicates the charging mode of the battery 118 by the charging device 117. (Step S4).

On the other hand, when communication between the auxiliary machine control device 221 and the display unit 114 is interrupted (step S2: NO), the charging mode determination unit 224 determines whether the key position of the key switch 115 is continuously on for 5 seconds. It is determined whether or not (step S5). If the key position of the key switch 115 remains in the ON position for 5 seconds (step S5: YES), the charging mode determination unit 224 determines that charging control is started, and determines the charging mode of the battery 118 by the charging device 117. The normal charging mode is determined (step S6). On the other hand, if the key position of the key switch 115 is not in the ON position for 5 seconds (step S5: NO), the charging mode determination unit 224 determines whether the key position of the key switch 115 is in the start position for 5 seconds. It is determined whether or not (step S7). When the key position of the key switch 115 is continuously at the start position for 5 seconds (step S7: YES), the charging mode determination unit 224 determines that charging control is started, and the charging mode of the battery 118 by the charging device 117 is determined. The uniform charge mode is determined (step S8). On the other hand, if the key position of the key switch 115 is not at the start position for 5 seconds (step S7: NO), the charging mode determination unit 224 determines whether or not the headlamp switch 111 is ON ( Step S9). When the headlamp switch 111 is ON (step S9: YES), the charging mode determination unit 224 determines that charging control is started, and determines the charging mode of the battery 118 by the charging device 117 to the reserved charging mode ( Step S10).
On the other hand, when the key position of the key switch 115 is in the OFF position and the headlamp switch 111 is OFF (step S9: NO), it is determined that the charging control is not started, and the auxiliary equipment control device 221 performs the process. Returning to S1, it is determined whether or not the power plug is connected.

  When the charging mode determination unit 224 determines the charging mode in step S4, step S6, step S8, or step S10, the charging control unit 225 controls the charging device 117 in the determined charging mode (step S11).

Thus, according to the present embodiment, the charging mode determination unit 224 controls the charging control based on the operation received by the headlamp switch 111 and the key switch 115 when communication with the display unit 114 is interrupted. It is determined whether or not to start. Further, the charging control unit 225 controls charging of the battery 118 based on the determination result. As a result, the vehicle control device 116 can control the charging of the battery 118 even if the auxiliary device control device 221 loses communication with the display unit 114. The display unit 114 is an example of an operation unit that receives an input of a charging instruction for the battery 118. The headlight switch 111 and the key switch 115 are an example of an operation unit that receives an operation related to the behavior of the forklift 100 during non-charging.
In the present embodiment, the charging mode determination unit 224 determines the charging mode in addition to the determination of whether to start the charging control, but in other embodiments, the present invention is not limited to this. For example, the charging mode determination unit 224 according to another embodiment may determine only whether to start charging control. In this case, the charging control unit 225 starts charging control in a predetermined charging mode (for example, normal charging mode).

Moreover, the vehicle control apparatus 116 determines a charging mode by operation received by the operation part which receives operation which concerns on the behavior at the time of non-charging among the various operation parts provided in the forklift 100. As a result, the vehicle control device 116 can control the charging of the battery 118 without interfering with the original operation of the operation unit. For example, when the emergency stop switch 112 for stopping the entire operation regardless of the state of the forklift 100 is used for the charge control, the emergency stop process cannot be performed during the charge control.
In other embodiments, an operation unit other than the headlamp switch 111 and the key switch 115 may be used as an operation unit that receives an operation related to the behavior during non-charging. For example, other operation units such as a direction indicator switch and a horn switch may be used as an operation unit that receives an operation related to the behavior during non-charging.

Thus, according to the present embodiment, the charging mode determination unit 224 determines the charging mode based on the operation received by the headlight switch 111 and the key switch 115 when communication with the display unit 114 is interrupted. To decide. In addition, the charging control unit 225 controls charging of the battery 118 based on the determined charging mode. As a result, the vehicle control device 116 can control the charging of the battery 118 even if the auxiliary device control device 221 loses communication with the display unit 114. The display unit 114 is an example of an operation unit that receives selection of a charging mode of the battery 118. The headlight switch 111 and the key switch 115 are an example of an operation unit that receives an operation related to the behavior of the forklift 100 during non-charging. Moreover, the vehicle control apparatus 116 determines a charging mode by operation received by the operation part which receives operation which concerns on the behavior at the time of non-charging among the various operation parts provided in the forklift 100. As a result, the vehicle control device 116 can control the charging of the battery 118 without interfering with the original operation of the operation unit. For example, when the emergency stop switch 112 for stopping the entire operation regardless of the state of the forklift 100 is used for the charge control, the emergency stop process cannot be performed during the charge control.
In other embodiments, an operation unit other than the headlamp switch 111 and the key switch 115 may be used as an operation unit that receives an operation related to the behavior during non-charging. For example, other operation units such as a direction indicator switch and a horn switch may be used as an operation unit that receives an operation related to the behavior during non-charging.

  In addition, according to the present embodiment, the charging mode determination unit 224 determines the charging mode of the charging device 117 regardless of the operation of the headlight switch 111 and the key switch 115 when communication with the display unit 114 is not interrupted. Is determined as the charging mode accepted by the display unit 114. Thereby, when the operation | movement of the display unit 114 is normal, it can prevent that the malfunctioning by the headlamp switch 111 or the key switch 115 arises. As an example of the malfunction caused by the headlight switch 111 or the key switch 115, the power plug is connected while the headlight switch 111 or the key switch 115 is turned on, so that charging in a charging mode not intended by the user is performed. Is made. Note that the charging mode determination unit 224 according to another embodiment may determine the charging mode by operating the headlamp switch 111 and the key switch 115 even when communication with the display unit 114 is not interrupted.

Further, according to the present embodiment, the vehicle control device 116 includes the main board 201 and the sub board 202 connected to each other. Further, the key switch 115 and the headlamp switch 111 are directly connected to the sub board 202 provided with the auxiliary machine control device 221. Thus, the vehicle control device 116 can control the charging mode by the headlamp switch 111 and the key switch 115 even if the power supply of the main board 201 is shut off at the time of key-off for power saving.
For example, when the accelerator lever 107 connected to the sub board 202 via the main board 201 is used for charging control, it is necessary to continue supplying power to both the main board 201 and the sub board 202 at the time of key-off. Note that the charging mode determination unit 224 according to another embodiment may perform charging control using an operation unit connected via another control board such as the main board 201. Moreover, although this embodiment is provided with the two bases of the main board 201 and the sub board 202, other embodiment is not restricted to this. For example, the vehicle control apparatus 116 according to another embodiment may include three or more control boards or one control board.

  Further, according to the present embodiment, the vehicle control device 116 includes the connection determination unit 222 that determines whether or not the power plug is connected to the forklift 100, and the headlight switch only when the power plug is not connected. 111 and a behavior control unit 226 that controls behavior based on an operation received by the key switch 115. In addition, the charging mode determination unit 224 determines the charging mode based on the operation received by the headlamp switch 111 and the key switch 115 when communication with the display unit 114 is interrupted when the power plug is connected. To decide. Thereby, the behavior of the headlamp switch 111 and the key switch 115 can be switched depending on whether or not the power plug is connected. That is, when the key position of the key switch 115 is started when the power plug is not connected, the behavior control unit 226 supplies the electric power of the battery 118 to each electric device. On the other hand, if the key position of the key switch 115 is fixed at the start position for 5 seconds when the power plug is connected, the charging control unit 225 charges the battery 118 in the equal charge mode. In addition, the vehicle control apparatus 116 which concerns on other embodiment may switch the function of the headlamp switch 111 and the key switch 115 by events other than the presence or absence of the connection of a power plug. For example, the vehicle control device 116 according to another embodiment may switch the functions of the headlight switch 111 and the key switch 115 based on ON / OFF of the deadman brake.

  As described above, the embodiment has been described in detail with reference to the drawings. However, the specific configuration is not limited to that described above, and various design changes and the like can be made.
