METHOD FOR ACTUATING AN ELECTRICALLY ACTUATED FRICTION BRAKE

摘要

To be able to selectively influence the braking effect of a friction brake (1) in a certain operating point to be able to reliably and easily achieve regulation or control of a required setpoint braking effect of the friction brake (1), it is proposed to determine an actuation energy (EE) of the electric motor (21) for the braking operation, and to determine the ascertained actuation energy (EE) as the actual actuation energy (EE—actual) in the predefined setpoint position of the friction brake (1), and to determine a setpoint actuation energy (EE—setpoint) with respect to the setpoint position or with respect to a setpoint braking effect from known data concerning the friction brake (1), and to compensate for a deviation between the actual actuation energy (EE—actual) and the setpoint actuation energy (EE—setpoint) by actuating the friction brake (1).

1. Method for actuating an electrically actuated friction brake (1) that is driven by an electric motor (21), in which for a braking operation, in order to achieve a predefined setpoint braking effect of the friction brake (1), a brake lining (3, 6) is pressed against a friction surface by setting a setpoint position of the friction brake (1) that is associated with the setpoint braking effect, characterized in that an actuation energy (EE) of the electric motor (21) is determined for the braking operation, and the ascertained actuation energy (EE) is determined as the actual actuation energy (EE_actual) in the predefined setpoint position of the friction brake (1), and a setpoint actuation energy (EE_setpoint) is determined with respect to the setpoint position or with respect to a setpoint braking effect from known data concerning the friction brake (1), and a deviation between the actual actuation energy (EE_actual) and the setpoint actuation energy (EE_setpoint) is compensated for by actuating the friction brake (1).
