The method includes: a pre-braking slope estimated value is determined according to a specified cycle, where a current pre-braking slope estimated value is determined and is used as a first slope estimated value a, and a pre-braking slope estimated value of a previous cycle that is latched prior to the establishment of brake pressure is used as a second slope estimated value a; an instantaneous vehicle speed vprior to the establishment of the brake pressure is latched, a vehicle traveling distance land time tare accumulated, and an in-braking slope estimated value ais determined based on the instantaneous vehicle speed v, the vehicle traveling distance l, and the time t; and pre-braking pressure p and in-braking pressure p are determined based on the second slope estimated value aand a third slope estimated value a, respectively, initial brake pressure p is determined based on the pre-braking pressure p and the in-braking pressure p, and final brake pressure p is determined based on the initial brake pressure p. According to the invention, the brake pressure can be accurately determined.",
