AUTO GUIDE VEHICLE

In the present invention, an auto guide vehicle (20) for transporting a cart (10) is characterized by being provided with: vertically extendable/retractable hydraulic cylinders (22) for causing exerting an upwardly thrusting push-up force to act upward on a floor the bottom surface of the cart (10); a hydraulic pressure supply device (70) for supplying a fluid to the hydraulic cylinders (22); pressure adjustment means (50) for adjusting the hydraulic pressures of the fluid supplied from the hydraulic pressure supply device (70) to the hydraulic cylinders (22); a control board (40) for outputting a hydraulic pressure command values to the pressure adjustment means (50); and a pressure sensors (100) for detecting the hydraulic pressures of the fluid supplied to the hydraulic cylinders (22),wherein the control board (40) calculates the command values by calculating a differential value the derivatives of the hydraulic pressures detected by the pressure sensors (100), estimating a point in time point at which the
