The present invention relates to a method for automatically controlling a transmission of a wheel loader, and more particularly, to an automatic control method for allowing a kickdown to be automatically performed in a specific stage such as excavation operation among a plurality of operational stages in which the wheel loader performs operations, and to this end, the method includes: receiving, by a transmission control unit, various information from a sensor of a transmission; receiving, by the transmission control unit, bucket position information from a boom angle sensor; and performing an automatic kickdown transmission from shift stage 2 to shift stage 1 when the received information satisfies a predetermined condition, and when the wheel loader brakes for an excavation operation, an automatic kickdown transmission is performed according to conditions of low engine RPM, low load and low travel speed and a condition in which the position of a bucket is adjacent to the ground level, and accordingly, the excavation operation starts at the state where the transmission is shifted to the shift stage 1 in advance, thereby improving work efficiency. |
