AI Technical Summary
Technical Problem
Existing wiper devices face challenges in achieving effective wiping during heavy rain conditions while minimizing power consumption, particularly due to variations in load conditions and vehicle electrification requirements.
Method used
A wiping device with a dual-motor drive system that switches to a narrow wiping range in heavy rain mode, utilizing brushless motors for precise control and reducing power consumption by limiting the wiping area to the minimum required for visibility.
Benefits of technology
The device achieves effective wiping during heavy rain without increasing power consumption by narrowing the wiping range to the legally mandated minimum, ensuring visibility while optimizing energy efficiency.

Abstract
Provided is a wiping device capable of performing wiping suitable for heavy rain without increasing power consumption. The wiping device wipes rainwater from a surface to be wiped by using a prescribed power source to cause a wiper blade to engage in reciprocating motion, in which the wiping device comprises a power source driving unit that sets the wiping range in a heavy rain mode narrower than the wiping range in a normal mode, and sets the wiping range in the heavy rain mode to the minimum wiping area stipulated by law.
