    • A windshield wiper drive device for driving a windshield wiper (11) in an alternating motion in a range of motion (17) between two turning point positions (A, C) includes a motor (1) for moving the windshield wiper (11), a detector (6) for detecting a time at which the windshield wiper (11) moves past a given position (A, C) in the range of motion (17), a control circuit (8) for reversing the direction of motion of the motor (1) at each turning point position (B, D), and an incremental transducer for detecting the distance traveled by the windshield wiper (11) from the given position (A, C). The control circuit (8) reverses the direction of motion of the motor (1) as soon as it is detected that the windshield wiper (11) has traveled a defined distance.
    • 用于在两个转折点位置(A,C)之间的运动范围(17)中以交替运动驱动挡风玻璃刮水器(11)的挡风玻璃刮水器驱动装置包括用于移动挡风玻璃刮水器(11)的马达(1) 检测器(6),用于检测挡风玻璃刮水器(11)在运动范围(17)内移动经过给定位置(A,C)的时间;控制电路(8),用于反转运动方向 在每个转折点位置(B,D)处的电机(1)和用于检测由挡风玻璃刮水器(11)从给定位置(A,C)行进的距离的增量传感器。 一旦检测到挡风玻璃刮水器(11)已经行驶了一定距离,控制电路(8)就会反转马达(1)的运动方向。
