The invention provides a steering braking method, device and equipment under an emergency working condition and a medium. The method comprises the following steps: acquiring a road curvature of a current road and a driving state of a vehicle on the current road; if the road curvature is larger than a preset curvature, the axle load transfer rate of the vehicle is obtained according to the driving state; according to the axle load transfer rate of the vehicle and the driving state, expected longitudinal acceleration and expected transverse acceleration are obtained; and the opening degree of a brake pedal of the vehicle is adjusted according to the expected longitudinal acceleration, and the wheel turning angle of the vehicle is adjusted according to the expected transverse acceleration. According to the method, the transverse acceleration and the longitudinal acceleration are effectively combined to conduct braking control on vehicle running, and the accurate and safe braking effect is achieved.
