Aiming at the problem of the failure in maintaining linear pressure-rise in ABS under low tem-perature, a self-stabilization condition for the opening of booster valve is derived through the force analysis of valve core. Numerical simulations on both electromagnetic field and flow field are conducted to analyze the effects of ambi-ent temperature on the electromagnetic and hydraulic forces. The results show that for meeting the self-stabilization condition of valve opening and hence assuring linear pressure-rise in ABS, the controlled temperature range should be -17℃ ~120℃, which is verified by a ABS test on HCU performance tester.
