ある。2. Description of the Related Art A working machine is a carrier used for cargo handling, a cultivator and a tractor used for farming, a lawn mower for cutting grass with a blade,
This is a general term for snowplows that remove snow. For example,
In the case of a cultivator, since it turns at the end of the cultivated land, a non-cultivated land called a headland is generated there. The less cultivated land is better, the better the cultivator is, the smaller the turning radius is, and ideally, the cultivator should turn as if it turns on the spot. Turning on the spot in this way is called "Shinchi-Senkai". Considering a transport vehicle that moves so as to sew between luggage, it is preferable to change the direction by pivoting. As described above, the working machine has a special situation that it is desirable to make a pivot turn at the work place.

ST01: First, it is checked whether or not the left turning switch is ON. If ON, the process proceeds to ST02, and if NO, the process proceeds to ST06. ST02: If YES in ST01, it is confirmed that the vehicle speed is zero or very slow. V0 means a very slow speed that does not interfere with a sharp turn. If the vehicle speed is V0 or higher,
Since it is NO, the process proceeds to ST03. ST03: The control section performs deceleration control to reduce the vehicle speed. This deceleration control is continued until ST02 is cleared. ST04: Since the two conditions that the left turning switch is ON (ST01) and the vehicle speed is lower than V0 (ST02) are satisfied, the control unit rotates the left electric motor in the reverse direction and the right electric motor in the normal direction. This starts a sharp left turn of the electric vehicle. ST05: When the left turning switch is turned off, the turning control is interrupted to return to the normal operation state.

を中断して通常運転状態に戻す。ST06: If NO in ST01, it is checked whether the right / left turning switch is ON. If it is ON, ST07, and if it is NO, the process exits from this control. That is, since neither the left or right turning switch is ON, the turning control is not performed. ST07: If YES in ST06, it is confirmed that the vehicle speed is zero or very slow. If the vehicle speed is equal to or higher than the very low speed V0, the process proceeds to ST08 since it is NO. ST08: The control unit performs the deceleration control to reduce the vehicle speed. This deceleration control is continued until ST07 is cleared. ST09: Since the two conditions that the right turning switch is ON (ST06) and the vehicle speed is lower than V0 (ST07) are satisfied, the control unit rotates the left electric motor forward and the right electric motor reversely. . This starts a sharp right turn of the electric vehicle. ST10: When the right turning switch is turned off, the turning control is interrupted to return to the normal operation state.

Then, a turn corresponding to the work mode of turning sharply at high speed during work at high speed and turning at low speed during work at low speed can be performed.

In (a), when the driver presses the right turn switch 25R as shown by the arrow, the left electric motor 13L rotates forward, and the left crawler 16L enters the forward state, and at the same time, the right electric motor 13L moves forward.
R reverses, and the right crawler 16R enters the retreat state.
If the center of the front and rear and left and right of the left and right crawlers 16L and 16R is the turning center G and the distance to the left corner of the bed 20 is R,
The electric vehicle 10 starts turning right with the turning center G as the center and the turning radius R as the center.

(C) shows a state where the vehicle has turned 180 ° to the right. It can be seen that the turning area falls within a circle having a radius R. Minimizing the turning area in this way is the aim of pivot turning. By arbitrarily operating the right turning switch 25R, the driver can start and end the right turning base turn. The same applies to a left turn type pivot turn.

According to the first aspect, in order to make a pivot turn, a left turn switch or a right turn switch always provided on the operation panel may be operated. By operating the left turning switch, the left electric motor rotates in the reverse direction and the right electric motor rotates in the forward direction, so that the left turning type pivoting can be executed. Similarly, if the right turn switch is operated, the left electric motor rotates forward and the right electric motor rotates reversely, so that a right turn pivot turn can be executed. Therefore, according to the present invention, the pivot operation is extremely easy, and the work efficiency can be improved.
