WORKING VEHICLE CONTROL APPARATUS |
摘要 |
A working vehicle control apparatus includes: a selection device that selects one of a power mode and an economy mode; a determination device that determines whether or not a speed restriction condition in which a speed ratio detected by the speed ratio detection device is equal to or less than a predetermined value and a load pressure detected by the load pressure detection device is equal to or greater than a predetermined value has been established; an engine rotational speed restriction device that restricts a maximum rotational speed of the motor upon selection of the economy mode to a lower speed side than a maximum rotational speed of the motor upon selection of the power mode when it is determined by the determination that the speed restriction condition has been established; and a vehicle speed restriction device that restricts a maximum vehicle speed upon selection of the economy mode to a lower speed side than a maximum vehicle speed upon selection of the power mode when it is determined by the determination device that a speed restriction condition has not been established. |
