Claim:
1. A method for determining an electromechanical clamping force generated by an electric brake motor of a parking brake of a vehicle, comprising: measuring current values of a motor current of the electric brake motor using a current sensor; determining a standard deviation from a current curve of the electric brake motor of the parking brake using a control device of the parking brake, the current curve being based on the measured current values; and determining the electromechanical clamping force based on motor parameters of the electric brake motor using the control device, wherein the control device is configured to calculate the motor parameters based on the measured current values when the standard deviation does not exceed a limit value, wherein the control device is configured to calculate the motor parameters based on a correcting current when the standard deviation exceeds the limit value, the correcting current being a product of (i) a measured current value obtained prior to the standard deviation exceeding the limit value and (ii) a scaling factor.
