Patent ID: 7677350

Claim:
A construction vehicle, comprising: an engine; an accelerator configured to control a rotation speed of the engine; a hydraulic pump configured to be driven by the engine; first and second hydraulic motors configured to be driven by pressured oil discharged by the hydraulic pump, the first and second hydraulic motors being configured to respectively generate a driving force for traveling; a driving shaft configured to receive the driving force from the first hydraulic motor and the driving force from the second hydraulic motor; a clutch configured to selectively switch between a transmission state and a non-transmission state of the driving force from the second hydraulic motor to the driving shaft; an accelerator opening degree detection unit configured to detect an accelerator opening degree; a vehicle velocity detection unit configured to detect a vehicle velocity; and a control unit configured to determine a switchover velocity depending on the accelerator opening degree detected by the accelerator opening degree detection unit, the control unit being configured to control the clutch to switch between the transmission state and the non-transmission state when the vehicle velocity detected by the vehicle velocity detection unit reaches the switchover velocity.
