    • The present invention relates to an apparatus and a method for controlling a wiper (85) which smoothly starts to move the wiper (85) at different wiping speeds from an initial position (88) thereof in accordance with the detected amount of rain. The apparatus for controlling wiper (85) includes the sensor (100), a first comparator (200), an actuator (300), a second comparator (400), a memory (600) and a changing device (700). The sensor (100) detects amount of rain. The first comparator (200) compares the amount of rain detected by the sensor (100), with a small predetermined amount of drops of water. When the first comparator (200) determines the detected amount of rain is equal to or greater than the small predetermined amount of drops of water, the first comparator (200) outputs a first actuating signal. The actuator (300) starts to move the wiper (85) in accordance with receipt of the first actuating signal outputted from the first comparator (200). When the actuator (300) receives the first actuating signal the actuator (300) starts to move the wiper (85) at a low wiping speed and the actuator (300) outputs a pulse signal. The second comparator (400) compares the detected amount of rain with a large predetermined amount of drops of water. When the second comparator (400) determines the detected amount of rain is equal to or greater than the large amount of drops of water, the second comparator (400) outputs a second actuating signal. The memory (600) memorizes the second actuating signal outputted from the second comparator (400) and the memory (600) outputs the memorized signal. The changing device (700) for changing the wiping speed of the wiper (85) atthe time when the wiper (85) starts to move from the initial position (88) in accordance with the memorized second actuating signal outputted from the memory (600) at the time when the wiper (85) starts to move from the initial position (88), the changing device (700) changes the low wiping speed of the wiper (85) to the high wiping speed or the high wiping speed of the wiper (85) to the low wiping speed.

    • The present invention relates to an apparatus and a method for controlling a wiper (85) which detects the amount of rain positioned on a rain sensor (100) regardless of the wiping speed of wiper (85) and which smoothly moves the wiper (85) at different wiping speeds in accordance with the detected amount of rain. The apparatus for controlling wiper - (85) includes the rain sensor (100), a first comparator (200), an actuator (300), a second comparator ( 4 00), a timer (500), a memory (600) and a changing device (700). The rain sensor (100) is located on an exterior surface of a front windshield (84) of a vehicle and detects amount of rain which is positioned on the rain sensor (100). The wiper (85) wipes out the exterior surface of the front windshield (84) and moves from and returns to an initial position (88).
      The first comparator (200) compares the amount of rain detected by the rain sensor (100), after the wiper (85) wipes out the rain sensor (100), with a small predetermined amount of drops of water. When the first comparator (200) determines the detected amount of rain is equal to or greater than the small predetermined amount of drops of water, the first comparator (200) outputs a first actuating signal.
      The actuator (300) actuates the wiper (85) in accordance with receipt of the first actuating signal outputted from the first comparator (200). When the actuator (300) receives the first actuating signal the actuator (300) moves the wiper - (85) at a low wiping speed and the actuator (300) outputs a pulse signal.
      The second comparator (400) compares the detected amount of rain positioned on the rain sensor (100) after the wiper (85) wipes out the rain sensor (100) with a large predetermined amount of drops of water. When the second comparator (400) determines the detected amount of rain is equal to or greater than the large amount of drops of water, the second comparator (400) outputs a second actuating signal.
      The timer (500) receives the pulse signal and an output signal outputted from the actuator (300) and a changing device (700). The timer (500) outputs a clock signal having a long time period after the wiper (85) returns to the initial position (88) at the high wiping speed. The timer (500) outputs a clock signal having a short time period after the wiper (85) returns to the initial position (88) at the low wiping speed.
      The memory (600) memorizes the second actuating signal outputted from the second comparator (400) and the memory (600) outputs the memorized second actuating signal after expiration of either the long or short time period after the wiper (85) returns to the initial position (88) in accordance with the clock signal outputted from the timer (500).
      The changing device (700) for changing the wiping speed of the wiper (85) at the time when the wiper (85) returns to the initial position (88) in accordance with the memorized second actuating signal outputted from the memory (600).
    • 无论刮水器(85)的擦拭速度如何,该装置检测雨水传感器(100)上的雨量,并根据检测到的雨量平滑地使刮水器(85)以不同的擦拭速度移动。 用于控制刮水器(85)的装置包括雨水传感器(100),第一比较器(200),致动器(300),第二比较器(400),定时器(500),存储器(600) 装置(700)。 雨量传感器(100)位于车辆的前挡风玻璃(84)的外表面上,检测位于雨传感器(100)上的雨量。 刮水器(85)擦拭前挡风玻璃(84)的外表面并移动并返回到初始位置(88)。 第一比较器(200)比较雨水传感器(100)检测到的雨量,在擦拭器(85)将雨水传感器(100)擦去之后,预先给出少量的水滴。 当第一比较器(200)确定检测到的雨量等于或大于小的预定量的水滴时,第一比较器(200)输出第一致动信号。 根据从第一比较器(200)输出的第一致动信号的接收,致动器(300)致动刮水器(85)。 当致动器(300)接收到第一致动信号时,致动器(300)以较低的擦拭速度移动刮水器(85),致动器(300)输出脉冲信号。 第二比较器(400)比较雨水传感器(100)之后的雨量检测量,雨水传感器(85)将雨量传感器(100)与预定量的大量水滴擦除。 当第二比较器(400)确定检测到的雨量等于或大于大量的水滴时,第二比较器(400)输出第二致动信号。 定时器(500)接收从致动器(300)和改变装置(700)输出的脉冲信号和输出信号。 定时器(500)在擦拭器(85)以高擦拭速度返回到初始位置(88)之后输出具有较长时间周期的时钟信号。 定时器(500)在擦拭器(85)以低擦拭速度返回到初始位置(88)之后输出具有短时间段的时钟信号。 存储器(600)存储从第二比较器(400)输出的第二致动信号,并且存储器(600)在刮水器(85)返回初始位置之后的长时间或短时间段期满之后输出存储的第二致动信号 位置(88)根据从定时器(500)输出的时钟信号。 改变装置(700),用于根据从存储器(600)输出的存储的第二致动信号改变擦拭器(85)返回到初始位置(88)时刮水器(85)的擦拭速度。
