The invention relates to a method for regulating the clamping force (F *) exerted by an electromechanical brake (B) of a motor vehicle, the brake (B) comprising an electric machine provided with a spindle intended to drive a brake mechanical clamping means, said electric machine being controlled by a voltage command of the PWM type, according to the invention, the rotational speed (omega) of the motor is estimated on the basis of an estimated value (R *) of the resistance of the motor and an estimated value (K *) of the constant of the motor, and then the clamping force (F *) is determined on the basis of the estimated value (omega) of the rotational speed of the motor, characterized in that the estimated value (R *) of the resistance of the motor is updated in an inactive phase ("idle phase") without a voltage command.
本发明涉及一种用于调节机动车辆的机电制动器(B)所施加的夹紧力(F*)的方法,该制动器(B)包括设有旨在驱动制动器机械夹紧装置的转轴的电机,所述电机通过PWM类型的电压指令来控制,其中,基于电机电阻的估计值(R*)和电机常数的估计值(K*)来估计所述电机的转速(ω),然后基于所述电机的转速的估计值(ω)来确定所述夹紧力(F*),其特征在于,在没有电压指令的非活动阶段(“空闲阶段”),更新所述电机电阻的估计值(R*)。
