  "textContent": "A wiper motor control circuit controls a drive circuit such that an actual speed of a wiper speed computed based on change in a rotation angle of an output shaft of the wiper motor detected by a rotation angle sensor that detects the rotation angle becomes a target speed corresponding to a position of a wiper blade indicated by the rotation angle detected by the rotation angle sensor. The wiper motor control circuit also controls the drive circuit so as to apply a braking current in the wiper motor when the actual speed has exceeded a threshold value when the rotation angle detected by the rotation angle sensor indicates a return position of the wiper blade.",
