摘要:
The invention relates to a method for operating a direct wiper drive having a motor, in particular for a windshield wiper. The method comprises reading out at least one characteristic curve from a memory and operating the wiper direct drive at an angle- and direction-dependent torque, corresponding at a maximum to a value of the angle- and direction-dependent characteristic curve, wherein the characteristic curve comprises at least the following values: a first, maximum value for upward wiping at a first wiping angle between a lower turning location and an upper turning location; a second value for upward wiping at a second wiping angle between the first wiping angle and the upper turning location, wherein the second value for upward wiping at the second wiping angle is less than the first, maximum value for upward wiping at the first wiping angle; a first, maximum value for downward wiping at a wiping angle between the upper turning location and the lower turning location, wherein the first, maximum value for downward wiping is greater than the first, maximum value for upward wiping; and a second value for downward wiping corresponding to a wiper position at the second wiping angle, wherein the second value for downward wiping is greater than the second value for upward wiping.
