Summary: | The invention discloses a bulldozer working device automatic control method. The method includes: acquiring the input rotation speed of a torque converter; acquiring the output rotation speed of the torque converter; calculating according to the input rotation speed and the output rotation speed to obtain the transmission ratio i of the torque converter; judging whether the transmission ratio i is in the range of i1-i2 or not, wherein i1-i2 is the transmission ratio range corresponding to the efficient working area of the torque converter; if so, keeping the current load of a working device, if i is smaller than i1, controlling the working device to reduce the load until the transmission ratio i falls into the range of i1-i2, and if i is larger than i2, controlling the working device to increase the load until the transmission ratio i falls into the range of i1-i2. By the method, the bulldozer working device can automatic ascend or descend according to different working conditions, labor intensity of operator |
