Motor control device for working vehicle |
摘要 |
A working vehicle motor control device includes: a rotational speed control device that controls a motor rotational speed in accordance with an operation amount of an accelerator pedal; a travel drive device that transmits rotation of the motor to wheels through a torque converter and a transmission; a speed ratio detection device that detects a speed ratio of an input shaft and an output shaft of the torque converter; and a speed restriction device that restricts a maximum rotational speed of the motor in accordance with a speed ratio detected by the speed ratio detection device. In the working vehicle motor control device, the speed restriction device restricts the maximum rotational speed when a detected speed ratio is in an acceleration region of the motor rotational speed to less than the maximum rotational speed when a detected speed ratio is in a non-acceleration region. |
