The invention relates to the technical field of bulldozer steering and braking control, and discloses a bulldozer steering and braking control method. The bulldozer steering and braking control methodcomprises the following steps: in the steering process, a steering proportional valve is electrified at t0 time, and the current value is gradually increased to a first preset value along with time between the t0 time and t4 time; the current of a braking proportional valve is gradually reduced to a second preset value between t2 time and t5 time; a braking clutch comprises a braking combinationbeginning point t3 between the t2 time and the t5 time; and a steering clutch friction plate is totally separated before the braking combination beginning point t3, wherein t0 is not more than t2 lessthan t3 less than t5. The problem of influence on the steering operation comfort by high steering and braking impact due to high combination speed of the steering clutch friction plate and a brakingclutch friction plate in the electric control steering and braking process of a bulldozer is solved.
