摘要:
A control unit in a work vehicle executes a brake control. The control unit determines whether the vehicle speed is equal to or greater than a predetermined threshold when the parking brake operating member is operated under the brake control. The control unit decreases the displacement of the hydraulic pump and increase the displacement of the first hydraulic motor without activating the parking brake when the vehicle speed while the vehicle is traveling is equal to or greater than the predetermined threshold. The control unit then activates the parking brake when the vehicle speed is less than the predetermined threshold.
摘要(中):
作业车辆的控制单元执行制动控制。 当驻车制动操作构件在制动控制下被操作时,控制单元确定车速是否等于或大于预定阈值。 当车辆行驶期间的车速等于或大于预定阈值时,控制单元减小液压泵的排量并增加第一液压马达的排量而不激活驻车制动器。 当车速小于预定阈值时,控制单元启动驻车制动器。
