Abstract:
A control device for a wiper device (10) of a window wiper apparatus (2), said control device (1) comprising means for controlling a cyclic oscillation of at least one wiper arm (5) of the wiper device (10) over a wiping angle (&agr;) defined by two turning points (O, U), wherein the control device (1) performs an adjustment of a set value of the wiping angle (&agr;) to changing operating conditions by means of a monitoring-assisted process and a mathematical trajectory model (6) of dynamic properties of the window wiper apparatus (2) formulated in the control device (1), wherein the wiper device (10) includes at least one motor (3) for driving said at least one wiper arm (5) and said dynamic properties include a characteristic of said at least one motor, elasticity of the control device and inertial moments of the control device and a load moment, said load moment being defined as a perturbing variable of the trajectory model (6).
