An electromechanical brake includes: a brake disc; a friction block; a pressing unit configured to press the friction block toward the brake disc; the motor is used for providing power for the pressing unit; a current sensor; a position sensor configured to measure a position of the pressing unit; and an initial position calculation unit that calculates at least one of an initial position or a contact point of the pressing unit, in which the pressing unit is configured such that a first current is measured at a first check point and a second current greater than the first current is measured at the second check point through the first check point and the second check point, the initial position calculation unit calculates at least one of the initial position or the contact point based on the first current, the first check point, the second current, and the second check point.
一种机电制动器,包括:制动盘;摩擦块;按压单元,其被配置为朝向所述制动盘按压所述摩擦块;电机,向所述按压单元提供功率;电流传感器;位置传感器,其被配置为测量所述按压单元的位置;以及初始位置计算单元,其计算所述按压单元的初始位置或接触点中的至少一个,其中所述按压单元被配置为通过第一检查点和第二检查点,在第一检查点处第一电流被测量,在第二检查点处大于所述第一电流的第二电流被测量,其中,所述初始位置计算单元基于所述第一电流、所述第一检查点、所述第二电流和所述第二检查点计算所述初始位置或所述接触点中的至少一个。
