- the CAN of the tractor 1 is connected to a communication control unit 73 that performs communication control in the network.
- the communication control unit 73 may be included in the control device 3 (see FIG. 11).
- the communication control unit 73 is configured to be able to control the engine rotation speed, the transmission gear ratio of the transmission 13, and the like by communicating with each component (engine 12, transmission 13, etc.) of the tractor 1. For example, the communication control unit 73 acquires the operation amount of the shift lever 172 and communicates with the engine 12 to change the engine rotation speed to a rotation speed corresponding to the operation amount of the shift lever 172. Thus, the operator can obtain a desired engine rotation speed by operating the shift lever 172. At this time, the communication control unit 73 changes the engine rotation speed so as not to exceed the rotation speed set by the speed dial 169.
- the communication control unit 73 acquires the operation amount of the shift lever 163 and communicates with the transmission 13. Then, the communication control unit 73 changes the inclination angle of the movable swash plate of the hydraulic pump in the continuously variable transmission of the transmission 13 according to the operation amount of the shift lever 163 by communication with the transmission 13. As a result, the operator operates the shift lever 163 to change the rotational speed of the transmission output shaft (not shown) of the transmission 13 steplessly.

- the communication control unit 73 can communicate with each configuration of the tractor 1 such as the engine 12 and the transmission 13 so as to be interlocked with the operation of the front loader 80. That is, the communication control unit 73 communicates with the engine 12 and the transmission 13 so that the engine rotation speed, the transmission gear ratio of the transmission 13, and the like are automatically changed according to the operation amount of the front loader 80.
- the communication control unit 73 automatically increases the engine rotation speed when the load on the front loader 80 is increased during the operation of the front loader 80 such as the raising / lowering of the arm 82 or the rotation of the bucket 83. It is configured as follows. According to this configuration, when the load on the front loader 80 increases, the amount of hydraulic oil supplied to the elevating cylinder 84 and the rotating cylinder 85 (both see FIG. 11) can be automatically increased. Therefore, the work by the front loader 80 can be carried out smoothly.
- the operation of increasing the load of the front loader 80 includes a case where the height position of the arm 82 is raised and a case where the bucket 83 is operated in a squeeze posture.
- the communication control unit 73 When the joystick 8 of the front loader 80 is operated by the operator, information on the operation amount is transmitted to the communication control unit 73.
- the communication control unit 73 detects that the operating load of the front loader 80 increases based on the acquired operation amount information of the joystick 8, the communication control unit 73 increases the engine rotation speed by communicating with the engine 12.
- the communication control unit 73 When the communication control unit 73 detects that the joystick 8 of the front loader 80 has been returned to the neutral position, the communication control unit 73 communicates with the engine 12 to automatically increase the engine rotation speed to the rotation speed immediately before increasing the rotation speed. To return. Thereby, after the operating load of the front loader 80 is eliminated, the engine rotation speed automatically returns to the original rotation speed, so that the load on the engine 12 can be prevented from continuing.
- the communication control unit 73 automatically changes the transmission ratio of the transmission 13 by communicating with the transmission 13 (specifically, the movable control unit 73 is movable). Automatically change the tilt angle of the swash plate).
- the communication control unit 73 controls the transmission 13 so that the rotational speed of the speed change output shaft of the continuously variable transmission is kept constant by such exchange of information. That is, the communication control unit 73 communicates with the transmission 13 so that the transmission gear ratio of the transmission 13 is automatically changed.
- the engine speed cannot be changed at all timings intended by the operator.
- the communication control unit 73 does not automatically increase the engine rotation speed.
- the speed change lever 172 can be changed at an arbitrary timing.
- the operator must release his / her hand from the joystick 8 when trying to operate the shift lever 172 while operating the steering handle 164 with one hand, for example.
- the traveling speed also changes.
- the tractor 1 is configured such that when the engine rotation speed up button 70 provided on the joystick 8 is operated, the rotation speed increases to the maximum rotation speed while maintaining the traveling speed.
- the engine speed up button 70 is operated from the joystick 8, information to that effect is transmitted to the communication control unit 73.
- the communication control unit 73 detects that the engine rotation speed up button 70 has been operated, the communication control unit 73 communicates with the engine 12 and the transmission 13 so as to keep the rotation speed of the transmission output shaft of the continuously variable transmission constant ( While changing the gear ratio of the transmission 13 (to keep the running speed constant), the engine speed is increased to the maximum speed.
- the operator can increase the engine rotation speed while maintaining the traveling speed at an arbitrary timing.
- the engine speed up button 70 when the engine speed is increased by operating the engine speed up button 70, the neutral operation of the shift lever 163 and the depression of the clutch pedal 167 are not conditioned.
- the communication control unit 73 increases the engine rotation speed to the rotation speed set by the speed dial 169. This is convenient because the engine rotation speed can be increased to the rotation speed desired by the operator by a simple operation of operating the engine rotation speed up button 70. In addition, since the upper limit of the engine rotation speed is provided as described above, it is possible to prevent the engine 12 from unnecessarily rising to a high rotation.
- the joystick 8 is provided with a maximum travel speed up button 71 and a maximum travel speed down button 72 for changing the maximum travel speed (see FIG. 6).
- the maximum traveling speed can be changed by operating the joystick 8.
- the communication control unit 73 detects that the maximum traveling speed up button 71 has been operated, the communication control unit 73 changes the set value so that the maximum traveling speed increases.
- the communication control unit 73 changes the set value so that the maximum travel speed decreases.
- the “maximum traveling speed” is to set the traveling speed when the shift lever 172 is operated to the maximum. For example, by setting the maximum travel speed to be low, the change in travel speed with respect to the operation amount of the shift lever 172 is reduced. On the other hand, by setting the maximum traveling speed high, the variation in traveling speed with respect to the operation amount of the shift lever 172 becomes large. Therefore, such a setting is effective when the tractor 1 is traveling at a relatively high speed, such as when traveling on the road.
- the setting of the maximum travel speed when the setting of the maximum travel speed is changed, the correspondence between the operation amount of the speed change lever 172 and the travel speed changes, and as a result, the travel speed corresponding to the current operation amount of the speed change lever 172 changes. Accordingly, when the setting of the maximum travel speed is changed, the current travel speed changes without operating the speed change lever 172. As described above, the setting change of the maximum traveling speed can also be used to change the current traveling speed without operating the shift lever 172.
