A position detection device and a position control device for a work vehicle are provided to detect the tilt angle of the work vehicle properly based on a horizontal base surface even when there are effects of acceleration or pivoting. A position detection device for a work vehicle includes a gravity type tilt angle sensor(24), an acceleration detecting unit(200) and a tilt angle detecting unit(300). The acceleration detecting unit(200) detects acceleration when the vehicle moves in front and rear directions of the vehicle. The tilt angle computing unit(300) obtains a tilt angle of the vehicle based on a horizontal base surface. The tile angle computing unit(300) obtains the tilt angle based on the tilt angle correction information and the detected value of the tilt angle sensor(24) that are obtained based on the acceleration detected by the acceleration detecting unit(200). |
