To provide a wiper control unit capable of inspecting conditions of a wiper motor and a drive circuit with a simple configuration.SOLUTION: A wiper control unit includes: a voltage dividing circuit that includes a resistance R2 one end of which is connected to a positive pole of a battery as a power supply and the other end of which is connected to a first terminal 120 as one of motor terminals of a wiper motor 18, and an FET2 one end of which is connected to the first terminal 120 of the wiper motor 18 and the other end of which is grounded, and that reduces a voltage of the battery to an inspection voltage at which the wiper motor 18 does not rotate. A microcomputer 58 detects a voltage output from the voltage dividing circuit through the first terminal 120 of the wiper motor 18 and the wiper motor 18 to a second terminal 122 as the other of the motor terminals of the wiper motor 18 as a detected voltage, and calculates a motor terminal voltage as a difference of voltages between the first terminal 120 and the second terminal 122 from the detected voltage.SELECTED DRAWING: Figure 3

    【課題】簡易な構成でワイパモータ及び駆動回路の状態を検査可能なワイパ制御装置を提供することを目的とする。【解決手段】一端が電源であるバッテリの正極に接続されると共に他端がワイパモータ18の一方側のモータ端子である第1端子120に接続された抵抗R2と、一端がワイパモータ18の第1端子120に接続されると共に他端が接地されたFET2とで構成され、バッテリの電圧をワイパモータ18が回転しない検査用電圧に減圧する分圧回路を有する。マイクロコンピュータ58は、当該分圧回路からワイパモータ18の第1端子120とワイパモータ18とを介してワイパモータ18の他方側のモータ端子である第2端子122に出力された電圧を検知電圧として検出し、当該検知電圧から第1端子120と第2端子122との電位差であるモータ端子電圧を算出する。【選択図】図3
