Title:
作業車両及び作業車両の制御方法
Document Type and Number:
Japanese Patent JP6444301
Kind Code:
B2
Abstract:
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.
