Systems and methods for clamping force estimation are provided. In one example, operations include generating a displacement-torque curve based on displacement data and motor torque data of an electric motor of the EMB system for a braking episode having a switchover time. The operations also include determining a high torque value and a low torque value at the switchover time from the displacement-torque curve. The operations further include calculating a friction coefficient based on the high torque value and the low torque value. The operations yet further include determining a non-linear coefficient from the displacement-torque curve. The operations include estimating a clamping force for a constant speed based on the friction coefficient and the non-linear coefficient.
