Casement e.g. motorized lateral sliding door, controlling system for e.g. coupe cabriolet, has estimation and measurement block for supplying obstacle detection signal on output according to fault on controlled movement of actuator

摘要

The system has an actuator e.g. electrical gear motor, for opening/closing a casement, and a command block (52) for controlling a movement of the actuator with respect to a speed set point. An estimation and measurement block (55) supplies an obstacle e.g. infant finger, detection signal on an output (39) according to a fault of predetermined value on the controlled movement of the actuator, where a residual effort threshold is considered as the predetermined value of the fault.
