Abstract:
A construction vehicle includes a control unit configured to shift gear after performing pre-shifting to couple a target speed-change gear that corresponds to a target speed with a target speed-change shaft in non-transmitting state of rotation of the input shaft when the gear shift is performed from a current speed to the target speed, in a state in which the current speed gear that corresponds to the current speed step and the current speed-change shaft that corresponds to the current speed gear are coupled. When the vehicle speed detected by the vehicle speed detecting section is zero, the control unit is configured to perform pre-shift auxiliary control prior to the pre-shifting control to input the rotation of the input shaft to the target speed-change shaft in a state in which the target speed-change shaft is not coupled to the plurality of speed-change gears.
