• a control unit having a memory to store program instructions and a processor to execute the stored program instructions and configured to control an operation of one or more wipers equipped in the vehicle according to information sensed by the multifocal rain sensor,
• wherein the multifocal rain sensor includes:
• at least one light emitting unit configured to output light;
• a first reflective plate corresponding to the at least one light emitting unit and disposed at a position spaced apart from the at least one light emitting unit by a predetermined distance;
• a glass part reflecting light after the light is reflected by the first reflective plate and forming a sensing region;
• a second reflective plate re-reflecting the light reflected by the glass part;
• and
• a light receiving unit configured to receive the light reflected by the second reflective plate,
• wherein the second reflective plate includes a multifocal reflective plate having a plurality of focuses based on a vertical height of incident light that varies according to a change in thickness of the glass part.
