摘要： A wiper control device includes a wiper switch having a variable resistor which is switched to the respective resistance value corresponding to the respective operation mode of the wiper apparatus. An interface circuit is provided with a reference resistor and a capacitor. A microcomputer is provided with a reference charging port for changing the capacitor through the reference resistor, a detective charging port for changing the same capacitor through the variable resistor switched into various resistance values corresponding to the respective operation modes and a reading port for reading as to whether the capacitor is changed up to a predetermined potential level. The microcomputer determines the selected operation mode on the basis of a relative value calculated from the time required for charging the capacitor through the reference resistor by the reference charging port and the time required for charging the capacitor through the variable resistor of the wiper switch by the detective charging port.

摘要： A raindrop detector comprises a vibration detection unit, a signal converter unit for converting the electrical signal output from the vibration detection unit into a data signal, a memory for storing data of the data signal converted by the signal converter unit and for outputting a signal to a wiper motor, and a cancel circuit for cancelling the data. According to this invention, it is possible to improve the control accuracy of the wiper motor because the distance to send the data signals to the memory from the signal converter unit shortens and the data signal is independent of radio interference.
