Method for controlling and/or monitoring e.g. electromechanical brake, of motor car by electronic brake system, involves monitoring controller device using actuator position actual value and actuator position estimated value

摘要

The method involves determining an actuator clamping force actual value (F-ist) and an actuator position actual value (psi-ist) by a clamping force sensor (7) and a position sensor (8), respectively. A manipulated variable (U) is produced by a controller device (1) for controlling an actuator (2). An actuator position input actual value (psi-in-ist) is determined and/or the controller device is monitored using the actuator position actual value and an actuator position estimated value that is determined based on the actuator clamping force actual value. Independent claims are also included for the following: (1) a device for controlling and/or monitoring an electrically actuatable brake (2) an electronic brake system comprising a regulating and control unit.
