- the starter (not shown) Immediately start the engine 111 by the motor and start increasing the engine speed. Since the generator motor 113 can quickly shift to a high output state as compared with the engine 111, the delay of the cargo handling work can be suppressed to a small value, or the delay can be made almost zero.
- the clutch 112 is kept in the disconnected state.

- the ECU 135 controls the clutch 112 in a connected state so as to drive the cargo pump 117 with the large output of the engine 111.
- the driving of the generator motor 113 in the motor mode may be stopped, or the driving may be continued to assist the output of the engine 111.
- the engine 111 is idled or stopped in the third mode to improve energy efficiency (fuel efficiency). If the load increases more than (suddenly) beyond a predetermined value, switching to driving of the cargo handling pump 117 by the engine 111 (or driving of the cargo handling pump 117 by the engine 111 and the generator motor 113 in the electric motor mode) enables the large load by the engine 111. It is possible to carry out cargo handling lightly using the output. In addition, it is inevitable that a slight time lag will occur until the engine 112 in the idling state or the stopped state is shifted to the high output state and the clutch 112 is engaged, but during that time, the output of the generator motor 113 is reduced. Since it is possible to respond by increasing the load quickly, the efficiency of cargo handling work will not be reduced without worrying about delays in cargo handling work due to a decrease in operational responsiveness.
- the ECU 135 sets the clutch 112 to the connected state, drives the generator motor 113 in the motor mode, and starts the engine 111. It can also be configured to make it. By doing so, the dedicated starter motor can be eliminated, which contributes to the downsizing of the forklift 101 and reduces the number of parts and the manufacturing cost. Further, since the generator motor 113 in the motor mode is designed to have a larger torque than the starter motor, it is customary to reduce vibration during cranking.
- the engine 111 may be started by cooperation of the starter motor and the generator motor 113.
- the dedicated starter motor can be a small (inexpensive) motor having a small torque, so that the forklift 101 can be made compact and the manufacturing cost can be reduced.
- FIG. 2 is a block diagram showing the configuration of the forklift according to the second embodiment.
- the second embodiment is different from the first embodiment in that a CVT (stepless transmission) 114 is interposed between a generator motor 113 and an engine 111.
- the CVT 114 can control the gear ratio by a control signal from the ECU 135.
- the opening degree of the cargo handling lever detected by the cargo handling lever position sensor 145 during the cargo handling work in the third mode is increased. If the load increases, and the degree of increase in the load is equal to or greater than a predetermined value, the output of the generator motor 113 in the motor mode is increased, and the rotation speed of the engine 111 is immediately increased. Control to start. If the engine 111 is stopped, the engine 111 is started immediately and the engine speed starts increasing.
- the clutch 112 is kept in the disengaged state at the beginning when the control for increasing the engine speed is performed. Even at a stage lower than the rotation speed of the motor 113, if the engine rotation speed increased by the CVT 114 becomes equal to the rotation speed of the generator motor 113, the clutch 112 Is connected to perform control to shift to driving of the cargo handling pump 117 by the engine 111. At the beginning of the rotation speed increase control of the engine 111, since the clutch 112 is in the disengaged state, the power of the engine 111 is not transmitted to the CVT 114.
- the rotation speed after the shift was calculated based on the speed ratio of the detection sensor 152 and the CVT 114, and it was determined that the obtained rotation speed became equal to the rotation speed of the generator motor 113. In this case, the clutch 112 is brought into the connected state.
- the ECU 135 monitors changes in the rotation speeds of the engine 111 and the generator motor 113 by the rotation speed detection sensors 152 and 153, and responds accordingly to the CVT 114 Change the gear ratio. That is, the change ratio of the CVT 114 is controlled so as to maintain the synchronization state between the engine 111 and the generator motor 113. As a result, the driving force of the engine 111 can be transmitted to the loading pump 117 even before the rotation speed of the engine 111 increases to a low state force and becomes equal to the rotation speed of the generator motor 113.
- the engine 111 in the third mode, is set in a stopped state instead of idling, and when a sudden increase in the cargo handling load is detected, the generator motor 113 in the motor mode is detected. And at the same time, the clutch 112 is connected to cause the generator motor 113 to start the engine 111. It is possible.
- the output of the generator motor 113 is started by rotating the output shaft of the engine 111 in a form in which the output of the generator motor 113 is decelerated and the torque is increased by the CVT 114. Therefore, the engine 111 can be started without applying an excessive load to the generator motor 113.
- the dedicated starter motor can be omitted or reduced in size as in the first embodiment, thereby contributing to cost reduction and the like!
- CVT 114 is a force interposed between clutch 112 and generator motor 113.
- the position of CVT 114 is not limited to this configuration, for example, between clutch 112 and engine 111. It may be a configuration in which CVT114 is interposed!
- FIG. 3 shows a forklift according to a third embodiment.
- This forklift 101 is configured such that a one-way clutch 112 ′ is provided between a generator motor 113 and an engine 111 instead of the clutch 112 in the configuration of FIG.
- the cargo handling load increases due to, for example, an increase in the opening of the cargo handling lever detected by the cargo handling lever position sensor 145. If the value is equal to or more than the predetermined value, the output of the generator motor 113 in the motor mode is increased, and control is performed so as to immediately start increasing the rotation speed of the engine 111. If the engine 111 is stopped, the engine 111 is started immediately and the engine speed starts increasing.
- the one-way clutch 112 ′ is automatically connected when the rotation speed of the engine 111 gradually increases and becomes equal to the rotation speed of the generator motor 113. Is transmitted to the cargo handling pump 117.
