  "textContent": "A wiper control apparatus includes a combination switch 2, awipermotor 7, an autostop (AS) switch 8, a first semiconductor switch element 4 for on/off controlling energization of the wiper motor, a second semiconductor switch element 5 for turning on a closed circuit which passes a reverse current through the wiper motor 7 while the energization for the wiper motor 7 is off, a controller for ON/OFF controlling the first and the second semiconductor switch element, and a current limiting resistor R1 for limiting the current flowing the second semiconductor switch element 5. In this configuration, a wiper control apparatus can be provided which can solve the problem when the abnormality of short-circuiting downstream of the wiper motor occurs, is compact, reliable and surely operable using semiconductor switches and a digital-controlled controller.",
