Cleaning devices for vehicles, cleaning system for vehicles, and control method for cleaning system for vehicles

A vehicle cleaning device that removes an extraneous object collected on a cleaning subject of a vehicle, the vehicle cleaning device comprising:

• a cleaning liquid supply device mounted on the vehicle;
• and
• a wiper device including a wiper driver and a wiper blade that is arranged to be contactable with the cleaning subject, wherein:
• the wiper driver includes
• a linear movement portion that produces a linear movement based on supply of a cleaning liquid that is pressure-fed from the cleaning liquid supply device, and
• a movement converter that converts the linear movement into a pivoting movement, the movement converter and the linear movement portion being arranged beside each other at a pivot point of the wiper blade;
• the wiper device is configured to cause the wiper blade to perform a reciprocal wiping operation based on the pivoting movement of the movement converter;
• the linear movement portion includes:
• a piston that receives a pressure of the cleaning liquid that is pressure-fed from the cleaning liquid supply device and performs linear movement, and
• a shaft member that is coupled to the piston (i) for linear movement with the piston and (ii) to be rotatable relative to the piston;
• and
• the movement converter includes
• a conversion member that converts the linear movement of the shaft member into a rotation movement of the shaft member, and
• a drive member that is coupled to the wiper blade and is rotatable integrally with the shaft member.
