摘要:
A work vehicle and a method of controlling the work vehicle are provided, whereby a braking performance equivalent to that of a conventional torque converter type work vehicle can be exerted when an operator switches between forward movement and rearward movement in a power transmission of an HMT or EMT type. A control unit embedded in the work vehicle includes a clutch controlling unit and a motor controlling unit. The clutch controlling unit is configured to disengage a first clutch in a condition that the first clutch is engaged and a second clutch is disengaged, when a first moving direction inputted through an FR operating device as an instruction of the operator and a second moving direction determined based on a vehicle speed detected by a vehicle speed detecting unit are different from each other, and in addition, when and the vehicle speed falls in a preliminarily set first range. The motor controlling unit is configured to control a motor so as to reduce a relative rotational speed of the second clutch after the first clutch is disengaged.
摘要(中):
提供了一种作业车辆和一种控制作业车辆的方法,由此当操作者在HMT的动力传输中在向前运动和向后运动之间进行切换时,可以发挥与常规变矩器式作业车辆相同的制动性能,或者 EMT类型。 嵌入作业车辆中的控制单元包括离合器控制单元和马达控制单元。 离合器控制单元被构造为当通过FR操作装置输入的第一移动方向作为操作者的指示和确定的第二移动方向时,在第一离合器被接合并且第二离合器被分离的状态下使第一离合器分离 基于由车速检测单元检测到的车速彼此不同,并且此外当车速处于预先设定的第一范围时。 马达控制单元构造成控制马达以在第一离合器分离之后减小第二离合器的相对转速。
