Claim 5:
6. A method of controlling a wheel loader, the method comprising:
receiving shape information data for an object in front of a driver cabin of the wheel loader from an upper sensor installed in the driver cabin;
receiving shape information data for the object in front of a front body of the wheel loader from a lower sensor installed in the front body;
detecting, by a work apparatus position detector installed in the front body, a position of a work apparatus connected rotatably to the front body; and
calculating, by a processor, a distance to the object based on the shape information data of any one selected from the upper sensor and the lower sensor according to the detected position of the work apparatus,
wherein calculating the distance to the object comprises:
calculating the distance to the object based on the shape information data from the upper sensor when the detected position of the work apparatus is lower than a predetermined position; and
calculating the distance to the object based on the shape information data from the lower sensor when the detected position of the work apparatus is higher than the predetermined position, and

the method further comprises controlling the wheel loader to perform loading or unloading operation based on the calculated distance.
