Wiper control apparatus

A wiper control apparatus comprising:

• a position calculation section that calculates a position of a wiper blade on a windshield from a turning angle of an output shaft of a wiper motor, the turning angle being detected by a turning angle detection unit;
• a control section that,
• in a case in which an operation signal is inputted, controls the wiper blade to reciprocatingly move between a stop reference position and a reversing position on the windshield and to conduct a wiping movement on the windshield,
• in a case in which a stop signal is inputted, controls the wiper blade to stop on the basis of a calculated position of the wiper blade on the windshield and the stop reference position, and
• in a case in which the operation signal is subsequently inputted, sets a position at which the wiper blade is stopped as a new stop reference position and controls the wiper blade to conduct the wiping movement toward the reversing position from the new stop reference position;
• and
• a memory unit that memorizes the new stop reference position,
• wherein, if a position of the wiper blade on the windshield, that is calculated by the position calculation section in a case in which the operation signal is inputted, is different from the new stop reference position memorized by the memory unit, the control section
• calculates an additional applied voltage to be applied to the wiper motor for moving the wiper blade to the new stop reference position, and
• performs control to apply to the wiper motor both the additional applied voltage and a voltage that is to be applied to the wiper motor for causing the wiper blade to conduct the wiping movement from the new stop reference position.
